Sun Exposure: Benefits Beyond Vitamin D

Even Easier if You Have Apple System

Alternatively, if you have an iPhone or iPad you can download a free app called “D Minder”, which will make all the calculations for you. It was made by an Apple developer who was motivated to simplify the process after he watched the video above.

From a health perspective, it doesn’t make much sense to expose your skin to the sun when it is lower than 50 degrees above the horizon because you will not receive any valuable UVB rays, but you will expose yourself to the more dangerous and potentially deadly UVA rays. UVA’s have a longer wavelength than UVB and can more easily penetrate the ozone layer and other obstacles (like clouds and pollution) on their way from the sun to the earth. UVA is what radically increases your risk of skin cancer and photoaging of your skin. So while it will give you a tan, unless the companion UVB rays are available you’re likely doing more harm than good and should probably stay out of the sun to protect your skin.

During the times of the year when UVB rays are not present where you live you essentially have two options: You can use a safe tanning bed or oral vitamin D3.
