Further, using sunscreen daily will not eliminate the amount of vitamin D benefits offered by the sun. Research suggests children who spend more time in sunlight may be less likely to become nearsighted. Christopher Starr , MD, an ophthalmologist at Weill Cornell Medical College , says kids should spend an additional one to three hours a day outside, to stimulate dopamine production. Lack of dopamine causes elongation of the eye, resulting in nearsightedness.
However, exposure to sunlight does not seem to reverse the effects on kids who are already nearsighted. Sunlight plays a pivotal role in regulating our internal clock.
This clock, otherwise known as circadian rhythm, dictates our behavior based on time of day — like when to fall asleep, wake up, or eat. Light appears to be one of the main driving forces behind this clock. Through a process called entrainment, a person's circadian rhythm needs to reset every day in order to stay synced with changes in light.
This can occur because of changing seasons or moving to a new time zone. Research indicates entrainment takes place as a result of exposure to light and darkness. Regular exposure to sunlight trains your brain to sleep when it becomes dark, and as a result, it can help you get a better night's sleep. According to Adam Friedman , MD, professor and interim chair of dermatology at the George Washington University School of Medicine and Health Sciences, it's difficult to determine a standard amount of time one should spend soaking up the rays to ensure adequate vitamin D production.
For many people, 10 to 15 minutes of sun exposure per day is enough. However, the length of time will vary widely due to factors like skin color , elevation , and how close you are to the equator. In much of the US — that is anywhere roughly north of Arizona — the skin produces trivial amounts of vitamin D during fall, winter, and spring. Black people also do not make as much vitamin D , as darker skin pigmentation reduces production. Vitamin D is also critical for your immune system, and with consistent exposure to sunlight, you can help strengthen it.
A healthy immune system can help reduce the risk of illness, infections, some cancers, and mortality after surgery. Increased exposure to natural light may help ease the symptoms of seasonal affective disorder--a change in mood that typically occurs in the fall and winter months when there are fewer hours of daylight.
A study that followed 30, Swedish women revealed that those who spent more time in the sun lived six months to two years longer than those with less sun exposure.
Of course, a little sunshine can go a long way and too much is harmful for our skin. Depending on the shade of your skin, scientists estimate your body can produce vitamin D in about 5 to 30 minutes in the sun. If you're wearing sunscreen, you may not produce as much vitamin D. If you're outside for some much-needed vitamin D, don't expose bare skin longer than 5 to 30 minutes. Saturdays - a. Sundays - Closed. SelectHealth may link to other websites for your convenience.
