Breakthrough research: Why you need to start using sunscreen every day!
We always hear that we need to wear sunscreen every day, however, a new study from Australia proves that the benefits of daily sunscreen use are real and measurable. In this study, they followed 900 fair skinned volunteers who wore sunscreen at least some of the time. The participants were between the ages of 22 and 55 and two thirds of them also wore hats when in the sun. Half of the volunteers were instructed to continue their usual practices and the other half were told to apply sunscreen to their face, neck, arms, and hands every morning.
Skin aging was measured at the beginning of the study with a silicone mold that was applied to the top of the hands. Investigators measured aging by examining the lines in the silicone mold. A grade of zero represented no lines at all (like baby skin) and 6 represented deep grooves and wrinkles.
At baseline both groups had a score of 4. The two groups were re-examined four and a half years later. At the end of the study, the “daily” sunscreen group still had a median score of 4 but the “casual use” sunscreen group had worsened to a median score of 5. That means that in just four and a half short years there was a significant increase in skin aging with “casual sunscreen use”.
This study really emphasizes the importance of daily sunscreen use to all sun exposed areas (face/neck/chest/arms/hands). The results prove that you can actually prevent and delay aging if you use sunscreen every day. What makes this study particularly interesting is that the control group was actually relatively good with sunscreen. Most even wore hats when in the sun so they weren’t extreme sun-worshippers. This study really proves that incidental everyday sun exposure can significantly age your skin in less than five years. In addition, using sunscreen everyday on exposed areas will clearly stop or delay these signs of aging.
Read the tips below to get the most out of your sunscreen and remember to wear sunscreen every day.
1) Apply a penny-sized amount of sunscreen to cover the face.
Studies show that we don’t apply enough sunscreen. One study showed that we often achieve less than half the labeled SPF because we don’t use enough. In other words, an SPF of 30 becomes and SPF of 10 because we don’t apply enough so remember to apply sunscreen liberally to get the best results.
2) Apply sunscreen to your neck and hands.
This study looked specifically looked at aging on the hands. It proved that in less than five years, your hands could age by 20% if you are not applying sunscreen daily. Keep your hands looking young and apply sunscreen every day.
3) Choose a broad-spectrum sunscreen.
This study focused on aging, which is primarily caused by UVA damage. Both UVA and UVB radiation causes skin cancer so make sure your sunscreen contains both UVA and UVB protection.
4) Choose a sunscreen that also contains antioxidants.
Antioxidants make sunscreens work better by preventing free radical damage in the skin. Antioxidants like Emblica and green tea are especially useful because they have also been proven to help with pigmentation. So make sure your sunscreen also contains antioxidants for best results.
The health benefits of exercise are well known. It is not surprising that exercise improves your heart and lungs, but did you know that exercise could also help your skin. Here is a list covering the newest research on 5 surprising benefits of exercise for your skin
1) Exercise may improve acne
There is an often-shared myth that sweat from exercise causes acne. Multiple studies show that this is not the case. In one study they evaluated body acne in three groups. One group exercised 5 days per week and showered 1 hour after exercising, one group exercised 5 days per week and showered 4 hours after exercising, and one group did not exercise at all. At the end of two weeks they found no difference in body acne between the three groups. This study shatters the myth that sweat from exercise causes acne
In fact, exercise may in fact improve acne. In one study, women with abnormally high male hormones (also known as androgens) had lower androgen levels after regular exercise. Androgens are one of the many causes of hormonal acne in women.
These studies suggest that exercise certainly won’t hurt acne and may, in fact, make acne better.
2) Exercise decreases the risk of skin cancer
We are now learning that exercise reduces the risk of all types of cancer in fact, it may reduce your risk of skin cancer. In a recent animal study, mice that exercised had fewer skin cancers after 14 weeks when compared to controls that did not exercise. Researchers think that there is a link between excess fat and tumor growth, which could explain these interesting results. So please don’t use the sun as an excuse not to exercise. Instead exercise in the early morning or evening and, of course, wear sunscreen.
3) Exercise helps prevent psoriasis
In a recent study from Harvard School of Medicine, women who participated in vigorous exercise reduced their risk of developing psoriasis by 25-30 percent. This may be due to two well-known benefits of exercise, reduced inflammation and reduced stress. Inflammation is a major factor in psoriasis and, of course, stress makes all skin diseases, like psoriasis, worse. So if you have psoriasis or a family history of psoriasis, make sure you are exercising regularly.
4) Exercise helps prevent and treat varicose veins
Exercise is one of the most important and frequently overlooked treatments for people with varicose veins. This is because low impact exercise such as walking improves the muscle tone in the calves. Good muscle tone in this area helps to support the veins and improve blood flow back to the heart. Keep in mind, not all types of exercise are good for varicose veins. High impact exercises, such as running, may make them worse. However, low impact exercises along with compression stockings are simple interventions to improve circulation in people with varicose veins.
5) Exercise may help your skin look younger
There are many reasons why exercise can make you look younger. First, we all know topical antioxidants are important to prevent aging in our skin, but did you know that exercise increases antioxidant activity in our whole body! In one study, researchers found increased antioxidant activity in the blood of people immediately after exercising. Antioxidants prevent wrinkles and other signs of aging by combating damage to DNA and other vital structures in our skin cells.
Another often forgotten benefit of exercise is that it improves sleep. In one study, people who exercised over 20 minutes per day had 65% better sleep quality. We all know that a rested face is a youthful face, so exercise really helps our skin in that aspect.
Keep in mind that exercise also reduces stress and rapid weight fluctuations, which are other common causes of dull, tired, and sagging skin.
So there you have it, 5 absolutely indisputable reasons to start exercising. Your body AND SKIN will thank you for it!
