Vitamin D And The Sun

Studies have shown that Vitamin D and sunlight always go together but there are harmful affects of sun’s UV rays as well. The extra exposure to the sunlight can cause skin cancer in many people. Other studies and articles about sun and vitamin D show that the manufacturing of vitamin D helps in preventing certain amount of cancers. Vitamin D is produced which helps in limiting the overproduction of cells. It doesn’t mean that we should roam around without wearing sun block. The maximum time that you can spend in sun without wearing sunscreen is 10 to 15 minutes.

Since exposure to sunlight is essentially important for us, therefore we need to know what advantages this exposure has on humans. Vitamin D helps in absorbing the calcium and phosphate from the foods we eat and from the UV rays of sunlight. Bones and teeth are deformed if insufficient amount of vitamin D is provided. Recent studies have shown that vitamin D can help in preventing certain cancers like breast cancer, colon cancer and prostate cancer. From different health studies and professional health articles, it comes to our knowledge that a child who is 1 year old needs around 10 micrograms of vitamin D per day. For adults who are more than 71 years old, require 15 micrograms of vitamin D per day.
