Vitamin D increases bone strength, lowers blood pressure and reduces the risk of heart attacks, diabetes and rheumatoid arthritis. Even in the sunniest places, Vitamin D is one of the most lacking nutrients in humans worldwide. It’s estimated that 40 percent of American adults have a vitamin D deficiency. The shortfalls in vitamin D stretch across all ages and ethnic groups. People are too worried about vitamin D, and the risk of skin cancer is SO much greater than low vitamin D. Vitamin D is crucial for our health and is most commonly made in the body when our bare skin is exposed to UVB radiation.
Vitamin D is usually called “the sunshine vitamin.” When your skin is exposed to sunlight, it makes vitamin D from cholesterol. The sun’s UVB rays hit cholesterol in the skin cells, providing energy for vitamin D synthesis to occur. Vitamin D has many roles in the body and is essential for optimal health. For example, it instructs the cells in your gut to absorb calcium and phosphorus which are two minerals that are essential for maintaining strong and healthy bones. If people use an SPF 30 sunscreen, then only 93% of the rays are blocked, and enough sun can get through to provide enough vitamin D.
As far as official sun exposure recommendations for the sake of vitamin D, expert opinions vary. The exact amount of sun and on how much skin depends on the person, and more specifically, on his or her skin tone. The darker the skin, the more sun exposure is needed. Age plays a role, too. The older the person, the more sun exposure is needed to reach vitamin D levels. Up to two hours of direct sun exposure a day is necessary in winter to absorb enough vitamin D, while just 30 minutes or less is needed in summer months.
People use sunscreen to protect their skin against sunburns and skin cancer. Most sunscreens contain chemicals that either reflect, absorb, or scatter sunlight. When this happens, the skin is exposed to lower levels of harmful UV rays. Several studies have shown that wearing sunscreen only has a small impact on your blood levels during the summer.
People usually think that sunscreen prevents us from getting the vitamin D that we need in our everyday lives. There have been studies done, and using sunscreen does not affect you getting your daily dose of Vitamin D. From one of our dermatologists here at Affiliated Dermatology, Dr. Andrew Newman explains the importance of sunscreen,
While sunlight is amazing for vitamin D production, too much can be dangerous. Some consequences include:
Although sunlight is great for making vitamin D, too much sun exposure can be very dangerous. If you plan on spending a lot of time in the sun this summer, make sure to avoid getting sunburned. It is best to reapply sunscreen every one to two hours especially if you’re sweating or bathing.
Your food. If you’re not getting enough sun exposure, the right foods and supplements can help boost vitamin D levels. If you’re worried about your vitamin D levels, then be aware that the majority of our vitamin D comes from our diet rather than the sun. Many fishes and vitamin D-fortified foods are available. Only a handful of foods contain significant amounts of vitamin D. These would consist of fatty fish such as salmon, mackerel and tuna are especially good sources. Small amounts are also present in egg yolks, beef liver and cheese. And many common foods such as milk and orange juice are filled with vitamin D. That being said, you would need to eat them nearly every day to get enough vitamin D.
Take Vitamin D supplements. This vitamin is readily available and becoming a superhero in the world of medicine to further reduce the inflammation in your skin after a sunburn. Most people require supplements to get the vitamin D they need. It’s the main benefit of a daily multivitamin; most provide 400 IU. Remember to read the labels carefully so you won’t get too little or too much. And although cod liver oil is rich in vitamin D, it has too much vitamin A for regular use.
