8 Little Known Facts About Sunscreen

Sunscreen should be just one tool in your arsenal. These eight little-known facts about sunscreens will help you spot problem products and avoid getting burned.

1. There’s no proof that sunscreens prevent most skin cancer.

Rates of melanoma – the deadliest form of skin cancer – have tripled over the past 35 years. Most scientists and public health agencies – including the Food and Drug Administration itself – have found very little evidence that sunscreen prevents most types of skin cancer. 

2. Don’t be fooled by high SPF.

High-SPF products tempt people to apply too little sunscreen and stay in the sun too long. The FDA has proposed prohibiting the sale of sunscreens with SPF values greater than 50+, calling higher SPF values “inherently misleading,” but it has not yet issued a regulation that carries the force of law. Ten percent of sunscreens we evaluated this year advertised SPF values greater than 50+.

3. The common sunscreen additive vitamin A may speed development of skin cancer.

The sunscreen industry adds a form of vitamin A to 14 percent of beach and sport sunscreens, 15 percent of moisturizers with SPF, and 6 percent of lip products with SPF in this year’s database.

Retinyl palmitate is an antioxidant that combats skin aging. But studies by federal government scientists indicate that it may trigger development of skin tumors and lesions when used on skin in the presence of sunlight. Other governments warn that cosmetics may contribute to unsafe amounts of vitamin A, and recommend against using vitamin A-laden cosmetics on the lips and over large portions of the body. We recommend that consumers avoid sunscreens, lip products and skin lotions that contain vitamin A or retinyl palmitate, which is also called retinyl acetate, retinyl linoleate and retinol. 

4. European sunscreens provide better UVA protection.

Nearly every sunscreen sold in the U.S. claims to offer “broad spectrum” protection, which suggests they shield against harmful UVA rays. But many products are too weak to be sold in Europe, where standards are higher. In Europe, sunscreen makers can formulate their products with four chemicals that offer stronger protection from UVA rays. American manufacturers have been waiting for years for FDA approval to use these sunscreen ingredients. The FDA has asked for more safety data, but until the FDA approves these ingredients and lifts restrictions on combining certain active ingredients, Americans will not be able to buy sunscreens with the strongest UVA protection.  

5. Sunscreen doesn’t protect skin from all types of sun damage.

SPF measures protection from sunburn, but not other types of skin damage. The sun’s ultraviolet rays also generate free radicals that damage DNA and skin cells, accelerate skin aging and may cause skin cancer. American sunscreens can reduce these damages, but not as effectively as they prevent sunburn. People can run into problems if they pick a sunscreen with poor UVA protection, apply too little or reapply it infrequently. Sunscreen companies commonly add SPF boosters that inhibit sunburn but may not protect from other damages. The FDA should strengthen its regulations to ensure that sunscreens offer the best possible skin protection. 

6. Some sunscreen ingredients disrupt hormones and cause skin allergies.

Sunscreen is designed to be applied to large portions of the body, several times per day. Sunscreen ingredients soak through skin and can be detected in people’s blood, urine and even mothers’ breast milk. Several commonly used ingredients appear to block or mimic hormones, and others cause allergic reactions on sensitive skin. The FDA’s sunscreen rules grandfathered in sunscreen active ingredients that were already on the market. The agency has never reviewed evidence of ill effects of sunscreen ingredients. 

7. Mineral sunscreens contain nanoparticles.

Most zinc oxide and titanium dioxide-based sunscreens contain nanoparticles one-twentieth the width of a human hair, to reduce or eliminate the chalky white tint that larger particles leave on the skin. Based on the available information, We give a favorable rating to mineral ingredients in sunscreens, but the FDA should restrict the use of unstable or UV-reactive forms of minerals that would lessen skin protection.  

8. If you avoid sun, check your vitamin D levels.

Sunshine causes the body to produce vitamin D, a critical function that sunscreen appears to inhibit. Vitamin D, technically a hormone, strengthens bones and the immune system and reduces risks of breast, colon, kidney and ovarian cancers, and perhaps other disorders.

About 25 percent of Americans have borderline low levels of vitamin D, and 8 percent have a serious deficiency. Breast-fed infants, people with darker skin and people who have limited sun exposure are at greatest risk of vitamin D deficiency. Many people can’t or shouldn’t rely on the sun for vitamin D. Check with your doctor to find out whether you should be tested for deficiency, or should take seasonal or year-round supplements. 

Lifelong Tips For Weight Management

1. Eat to fuel your body.

Eating less is a good thing when you’re trying to lose weight, but restricting your calories too low may lead to binges and send you into the evil cycle of yo-yo dieting.

However, if you’re eating to the point of starving your body of necessary calories, your body adjusts by going into protection mode (it wants to preserve stored fuel) and slows down. In most cases, this means muscle loss. If you’re having trouble losing weight, try keeping a food journal and take a close look to see if you’re skimping on fuel.

2. Listen to your body.

This step may take a little time to learn. But I urge you to be patient with yourself, because becoming comfortable understanding your hunger quotient will definitely pay off. Getting used to eating to the point of contentedness, and not fullness, is crucial to long-term weight loss. When you conquer this tool, regardless of what you’re eating, you will never dramatically over consume.

3. Don’t count calories.

Meticulously counting calories will end up being more frustrating than useful. Calories in versus calories out is an old way of thinking. There is much more involved with losing weight (hormones and hydration to name a couple) than calories.

Focus on nutrient-dense, low-calorie foods such as vegetables to bulk up your meals. Also, lean protein (such as fish, poultry or plant protein) and a little bit of healthy fat at every meal.

4. Drink up.

Sip H2O throughout the day. Staying hydrated is majorly important whether you’re looking to lose 5, 10, 20 or 50 pounds. Heard this before? Bet you have. But are you doing it? No better time to start than now. Drinking water is important for all cellular functions, and hydration aids in weight loss. Not only that, the brain easily confuses thirst for hunger.

5. Don’t sweat the small stuff.

One meal will not change your body. It will take a consistent effort of many changes over time. Again, one meal will not change your body. So, don’t get stressed and obsess over every meal or snack gone wrong.

Being in the correct emotional state while trying to lose weight is just as important as what you eat. Throw out the “throw in the towel” mindset and believe that you can and you will lose weight. Even if you slip up and have a chocolate chip cookie.

6. Take control of your environment.

Are there certain snacks you keep around your house that you can’t help but nibble on? Is your desk at work so messy that you have a hard time focusing on a simple task? Cleaning, clearing out and decluttering what you can control will make a big difference in making improvements in your diet. Re-doing your morning routine is also a way to take control of your environment and routine.

7. Indulge consciously.

Losing weight does not mean you have to swear off raw cookie dough forever. You’re working on instilling new practices and habits into your everyday life, and that also means relearning how to indulge. When you indulge you’re actually more likely to stay on track with your new eating plan.

Choose your absolute favorite indulgence when the time is right, and skip the rest. Be conscious about what you’re eating in the moment and take time to enjoy the indulgence. This is different from reaching your hand over and over into a bag of M&Ms until the moment you’re surprised they’re gone. If you’re at your best friend's birthday party, and someone brought cookie dough, have a scoop. And enjoy the indulgence as part of the event and move right back onto your kale salad.

FWAV Is Now Offering Reflexology!

Overview

Reflexology is the ancient art of foot massage which originated in China and which was also known to the Ancient Egyptians. It is believed that energy runs through the body in channels known as meridians and that massage of the feet stimulates these energy channels, promoting healing and relaxation. Every part of the foot corresponds to an area of the body, and massage of the feet stimulates the corresponding part of the body so that receiving a reflexology massage is regarded as the equivalent of a full body massage.

Reduction of Stress

The most obvious effect of reflexology massage is that of stress reduction. The techniques of reflexology include finger or thumb walking--where the reflexologist walks the finger or thumb over different areas of the feet in a set sequence--and massage and kneading of the foot using the whole hand. The experience is generally firm, but gentle, and should never cause discomfort or pain. According to “The Complete Illustrated Guide to Reflexology,” people of any age or sex--the elderly, women, men, teenagers, children and babies--can derive positive benefits from reflexology.”

Although results vary from individual to individual, the soothing action of reflexology generally leaves the recipient feeling deeply relaxed and peaceful afterwards.

Pain Reduction

Reflexologists believe that that illness is caused by blockages in the meridians or energy channels. These blockages inhibit the flow of life enhancing energy, also known as ‘chi,’ causing the accumulation of negative energy, resulting in pain or disease. There are over 7,000 nerve endings in the feet, and these are connected to the whole body through the central nervous system, to the whole body. Massage of the feet, and therefore these nerve endings, stimulates the body, promoting self-healing. The massage is designed to restore the delicate balance between the different body systems and functions, and when this happens harmony is restored. As a consequence of this, and because reflexology is so relaxing, it is also very effective in pain relief, as tension is taken out of the body and stress reduced, so pain is also reduced.

Effects of Reflexology

Reflexology increases the flow of energy, increases the circulation and stimulates the digestive system. It is so effective at this that most people feel a need to pee after a session, and are nearly always thirsty, as toxins are eliminated from the body. It is also recommended that you do not drink alcohol in the 24 hours before or after a session, as the effects of the alcohol can be multiplied. It is also inadvisable to have reflexology if you have a pacemaker fitted, or if you have diabetes.

Movement Improves Brain Function at Any Age

By Cynthia Horner

We have a brain because we move. A sea squirt attaches itself to a rock so it no longer needs to move, then it does an extraordinary thing; it eats its brain, all other body functions continue without its brain. If we have a brain because we move, could movement enhance and improve the function of our brain? You betch ya.

Many animals survived by becoming faster, bigger or meaner but humans have survived by becoming smarter. When the food supply diminished, humans were forced to walk to find food. Before we learned to ride animals and long before the invention of automobiles people walked on average 12 miles a day. The human brain developed, not by sitting around but through movement. Humans grew up moving or they did not grow up at all.

Today with our high tech scanning devises we now understand why. What all this movement did for us was to increase out heart rate and changed our brains to function at its best for the entire time we were alive. Movement that increases heart rate, triggers the brain to make BDNF (brain derived neurotropic factor), which acts like a brain cell fertilizer and helps brain cells stay healthy. A healthy brain cell has a good cell membrane surrounding it. A good cell membrane allows charged particles in and out at just the right time, in turn causing the brain cell to fire on cue, not too early, not to late but right on cue. When a brain cell fires it wires or connects to other brain cells. The more firing and wiring in the brain the healthier and better functioning it is. We all want to think well and remember well even after we have been on earth six, seven or eight decades. Decreased brain function or neurodegeneration does not have to happen as we age.

Just how exercise changes brain function was what they found out at Central High School in Naperville Illinois, where they decided to teach kids how to monitor and maintain their health and fitness and as a direct result improved each participant’s academic performance. Each student was required to run a mile, three times a week, keeping at their target heart rate. What they saw in the first year was those who participated were more alert, their senses heightened, their focus and mood improved and they were less fidgety. The most impressive result was an increase in working memory and processing speed and an increase in their GPA. They then extended the fitness program to the middle school students. Naperville’s eighth graders were among 230,000 students from around the world to take the T.I.M.S.S. (Trends in International Mathematics and Science Study) a test that evaluates knowledge in math and science. In the past China, Japan and Singapore have outdone Americans in these subjects, but in 1999 one year after the new fitness program began; Naperville’s students finished sixth in math and first in science.

Can anyone, at any age improve brain function through movement? The answer is an astounding yes. Any kind of movement is good; dancing, walking, running, martial arts, swimming, rowing, biking or anyn other movement you may enjoy. How soon can you expect results? Some improvement happens immediately. A truly sharp brain can be described as improving cognitive flexibility and creativity; this is coming up with new ideas and thinking out of the box, not simply remembering past facts. To accomplish this several areas of the brain need to change; to best do this it is recommended to increase heart rate into your target zone for 20 to 30 minutes, 2 to 3 times a week, for 12 weeks. Mixing coordination exercises with aerobic activity will bring about improvement in many more areas of the brain including those involved with speech and balance which are complementary to thinking, creativity, memory and problem solving.  Decreased brain function does not have to happen simply because you are getting older. Movement is life, so make it a part of your life; all your life.

10 Amazing Benefits of High-Intensity Interval Training

Improved Insulin Sensitivity

Insulin sensitivity, or how well your cells respond to insulin, has a big impact on how well you tolerate carbohydrates, and whether those carbohydrates will affect your ability to mobilize fatty acids. Reduced insulin sensitivity means you need more and more insulin to do the same job. And since insulin is a storage hormone, when it’s high, it’s more difficult to lose fat.

Following just 2 weeks of HIIT, in which there was a total of only 15 minutes of exercise, insulin sensitivity was improved by 23% 

Produces the Afterburn Effect

Excess post-exercise oxygen consumption (EPOC), is the increased oxygen your body uses after an intense workout to erase its oxygen debt. It uses this oxygen to return the body to homeostasis.

That means it uses additional calories to perform tasks such as muscle repair and replenishment of fuel stores. EPOC is better known as the afterburn effect, which is the process of burning extra calories long after your workout is over.

When comparing HIIT to low-intensity exercise, your exercise intensity positively affects both the magnitude and duration of EPOC. In other words, the greater your intensity, the greater the afterburn effect.

Specifically Targets Stomach Fat

Yes, we all know that you can’t target fat loss per se. However, that’s not what we’re talking about here. Doing sit-ups isn’t going to target belly fat.

However, there are things you can do that will change the way you store and mobilize fat. The way you store fat is determined by many factors – genetics and hormones being two big ones. And the type of exercise you do affects your hormone profile.

Doing HIIT can create a metabolic environment that stimulates a higher proportional release of abdominal fat. You still lose fat all over, but a higher proportion comes off in the midsection.

High-intensity interval exercise three times per week for 15 weeks was compared to the same frequency of steady-state exercise, and only HIIT produced significant reductions in total body fat, subcutaneous leg and trunk fat, and insulin resistance.

Improved Vo2 Max

VO2 max is your body’s max capacity to transport and use oxygen during exercise. It is a great measure of physical fitness. Generally speaking, the higher your VO2 max, the better your fitness level. A higher VO2 max also means that you can exercise at greater intensities for longer periods of time.

The good news is that doing HIIT will result in significant improvements in VO2 max. This improvement can be achieved whether you are a beginner exerciser or an advanced athlete.

Creation of New Mitochondria

Mitochondria are little cell powerhouses that produce energy (ATP). In simple terms, they take the fat and carbohydrates you either eat or store and convert them to usable energy. The more mitochondria you have, the more efficiently your body utilizes the calories you consume.

The number of mitochondria you have can be increased by creating a demand for more energy production. In fact, HIIT is a potent stimulus for the creation of new mitochondria.

Boost Favorable Hormones

High-intensity interval training does more than just burn calories. It primes your body for fat loss by creating a favorable metabolic environment.

Internally, your body undergoes many hormonal changes in response to intense training. Specifically, HIIT boosts growth hormone and testosterone levels after just 10 minutes, and the amount secreted is correlated to your exercise intensity.

Growth hormone and testosterone are a potent combo for both fat loss and muscle growth. Engaging in HIIT will provide you with this amazing benefit.

Burns More Total Fat Compared to Endurance Training

Did you know you can burn more fat doing HIIT than your typical steady-state endurance training, even when burning a fraction of the calories? It’s true.

A study comparing a 15 week HIIT program to a 20 week endurance-training (ET) program showed that despite its lower energy cost, the HIIT program induced a more pronounced reduction in subcutaneous fat compared with the ET program.

When the scientists adjusted the numbers so the calorie burn was equal, the decrease in the sum of six subcutaneous skinfolds induced by the HIIT program was ninefold greater than by the ET program.

Builds Muscle While Losing Fat

Many people say you can’t build muscle and burn fat at the same time. While it can be difficult to put on a large amount of muscle mass while in a calorie deficit, you can certainly accomplish both goals concurrently.

In fact, a 12 week HIIT program has been shown to increase lean body mass, while at the same time reducing total body fat, abdominal and trunk fat, and visceral fat.

The additional muscle will pay dividends by increasing your resting metabolic rate so that you’re burning extra calories at all times of the day. Build muscle and lose fat, all while exercising for less time. Seems too good to be true, but it is.

Increased Capacity for Fat Oxidation

During exercise our bodies undergo all kinds of chemical reactions and stress adaptations. Our bodies literally change from the inside out. During HIIT specifically, we make changes to our physiology that enable us to burn more fat.

Just seven sessions of HIIT over 2 weeks induced marked increases in whole body and skeletal muscle capacity for fatty acid oxidation during exercise in moderately active women. HIIT causes changes to your body that increases its ability to burn fat.

The Intangibles 

We've listed out the science behind the benefits of HIIT, but that’s really just scratching the surface. High-intensity interval training also:

• Adds variety – there really is an endless combination of fitness activities that can be incorporated into a HIIT workout.

• Creates time efficiencies – you no longer have to slave away on the treadmill for an hour or more. The same benefits or more can be accomplished in under 20 minutes.

• No equipment necessary – no gym membership? No problem. All you need is your body to get a great workout.

How To Care For Your Workout Clothes

First things first
Try to avoid leaving sweaty clothes in your gym bag, crumpled up in your laundry basket or on the bathroom floor. Leaving sweaty items stashed somewhere can become a breeding ground for bacteria (and even mold) if they are left too long. Bacteria build-up is one of the main causes of smelly workout gear!

To soak or not to soak
Soaking in a solution of vinegar and water can help kill bacteria and sweaty odors on your clothing. It can also help break down any build-up from detergents, deodorant and skin cells (ewww!). Be careful when you pre-soak clothes though — especially if soaking clothes with bright colors and prints. It’s probably best not to leave your clothes to soak for longer than 30 minutes to an hour, to avoid causing any damage. Once they’ve had a soak, pop them in the wash as normal.

Setting your washing machine
Check the labels for specific washing information before you start! Lots of workout fabrics are best washed in cold water, as it helps to maintain their shape. Hot water might seem like the right idea to kill off bacteria, but it may be damaging to the fibers.

Detergents and softeners
There are specialty laundry products for sportswear, but you can use any standard laundry powder or detergent. Use the recommended amount of laundry powder for your load (or even a little less) so it rinses out properly.

Don’t use fabric softener on your activewear. At all. Softeners can actually lock in odors in the fabric. Most softeners work by coating fibers, which might stop those fancy moisture wicking fabrics from doing their job properly.

After the wash
Fresh air and sunny weather is a best friend to your activewear. Sunshine makes it hard for bacteria to grow, so your clothes shouldn’t take on any strange odors. Hanging everything inside out helps against fading. —  You'd hate having to throw away your favorite shorts because they are all faded!

Top tips for washing activewear:

•  Turn your workout clothes inside out before stuffing them into the machine (the gross stuff can collect on the inside!).

•  Wash really sweaty clothes as soon as you can to stop the smell getting trapped in the fibers.

•  Hand wash sports bras or use a lingerie bag for washing them in the machine (you can buy the bags at most bra shops). 

•  Don’t wash your activewear with clothing that has zips, velcro or any other item that might catch on the fabric and damage it. 

•  Don’t use the clothes dryer (even if you’re in a hurry) and skip the iron as well. It’s not good for workout clothes, and can even burn them! (Trust me, I know this first hand - hello holes in tops!)

Okay, so it might take a little effort to keep your activewear smelling fresh. But no one wants to worry about strange smells when trying to focus on your workout! Take care of your workout clothes and you should get more wear out of them as well. 

Everything You Need To Know About Sodium

ARE SALT AND SODIUM THE SAME?

No. Salt is a compound called Sodium Chloride while Sodium is a chemical element (Na) found in the Earth’s crust.

WHAT DOES SODIUM DO?

Sodium is an essential nutrient for human beings because it regulates blood volume, blood pressure, osmotic equilibrium and pH levels in our bodies. Sodium is also needed for your muscles and nerves to work properly. In fact, each of us needs a minimum of 500 milligrams of sodium a day. This is where salt, or Sodium Chloride, enters the picture. It’s the principal source of sodium in the human diet and one of our most ancient and ubiquitous food seasonings – in fact, for thousands of years, salting has been an important method of food preservation.

WHAT ARE SOME SOURCES OF SODIUM? 

Sodium occurs naturally in most foods such as celery, beets, milk and even our drinking water (although the amount varies depending on the source). These days, unfortunately, most of our sodium intake comes from processed foods: Monosodium glutamate, sodium nitrite, sodium saccharin, baking soda (sodium bicarbonate) and sodium benzoate can be found in items such as Worcestershire sauce, soy sauce, onion salt, garlic salt, potato chips and bouillon cubes. Processed meats like ham, sausage and bacon and canned soups and vegetables are all examples of foods that contain a lot of sodium. And of course, a drive-thru at McDonalds, or any other fast food restaurant, will leave you filled with food that’s extremely high in sodium.

CAN TOO MUCH SALT/SODIUM IN YOUR DIET BE HARMFUL?

Every person is unique and recommended sodium intakes will vary based on age, metabolism, amount of exercise/sweat, medications, etc. However, Health Canada sets the adequate intake of sodium for women at 1500 mg daily, and a tolerable upper intake level of 2300 mg/day. How much exactly is that? Well, 2300 mg is the amount of sodium that’s found in one teaspoon of salt. And recent research shows we’re consuming a lot more than that. The average North American man consumes about 3500 mg of sodium every day and women consume 2500 mg. There large amounts promote hypertension, an ailment that causes 7.6 million premature deaths worldwide. If you’re chronically eating a diet that’s high in salt you are at risk of high blood pressure, which in turn increases your risk of heart attack and stroke. There are also some studies that suggest too much salt consumption can increase the risk of osteoporosis and kidney problems.

SODIUM AND EXERCISE

When you perspire, your body loses sodium, potassium and other essential minerals and nutrients. If you’re hiking, jogging, kayaking or doing any athletic activity over long distances, and you don’t rehydrate properly, you could be contributing to a decreased blood/sodium concentration. And the result might be ringing in your ears or mild heart palpitations. (In extreme instances you could succumb to hyponatremia, a condition similar to dehydration in which nausea, muscle cramps, disorientation, slurred speech, and confusion may occur.) Does that mean you should drink Gatorade every time you exercise? Absolutely not! Gatorade is full of sugar and it’s not an effective electrolyte replenishment tool.

HOW TO LOWER YOUR SALT INTAKE

There are five easy ways to lower your daily salt consumption.
1. Avoid processed foods as one small meal could have twice the recommended daily intake of sodium. Stick to whole foods, vegetables and fruit.
2. Cook with less salt
3. Drink lots of water to flush excess salt
4. Sauna or steam to sweat out excess salts
5. If you’re experiencing a craving for salty foods, try these seasoning alternatives:
• Garlic powder (not garlic salt)
• Roasted garlic
• Granulated sea kelp or sesame seeds
• Onion powder (not onion salt)
• Lime or lemon juice
• Veggie Salt

• Nutritional Yeast
