The Benefits of Sunlight

Also, other things such as tall buildings, clothing, and air pollution can interfere with the sun’s rays which lowers the amount of UVB rays a person receives from the sun and the ability of the body to process enough Vitamin D. With aging, the body’s ability to absorb rays and transform them to Vitamin D lessens making it even more critical to get enough sunlight.

​Remember to get plenty of sunlight this winter.  Sunshine can elevate your mood due to the hormone, serotonin. It can be challenging to get enough sunlight in the winter because there aren't as many direct rays as during warmer months. 

There are many ways that our bodies are affected by Vitamin D. Not having enough of it has been linked to high blood pressure, infectious diseases, rheumatoid arthritis, psoriasis, and multiple sclerosis. It is also associated with having cancer, and some believe that it might help prevent cancers. In addition, studies have also found that lack of Vitamin D may cause painful joints in the elderly. Vitamin D is necessary for calcium and phosphorous absorption, which helps our bodies to build strong bones and teeth. The improved calcium absorption helps to regulate heartbeat and with blood-clotting, and phosphorous is important for muscle and nerve functions. 
 
One study at the University of Sydney found that sunlight raises the level of dopamine in the brain which may reduce the development of nearsightedness. A combination of calcium and vitamin D supplements may help prevent fractures in the elderly and reduce the likelihood of osteoporosis. Just as low levels of Vitamin D can adversely affect the body, high levels of Vitamin D can be toxic, so don’t overdo the supplements. It's a good idea to check with your doctor on the correct amount for you and remember to wear sunscreen to minimize risk of skin cancer.

Older adults may have challenges getting out in the winter due to snow, ice, or with avoiding cold weather. Even the busyness of the holiday season can interfere with getting enough Vitamin D in the winter. A mid-day walk may be an ideal solution because getting out midday is an opportunity to soak up maximum rays.
