Vitamin D helps produce immunocytes to prevent cancer and regulates the absorption of calcium to strengthen bones. Lack of vitamin D increases the risk of osteoporosis, bowel cancer and breast cancer.
The body needs vitamin D all year, but autumn is a season to take extra care, as it becomes difficult to obtain vitamin D naturally from the sun in the winter months from December to February.
Kwon Kil-young at Eulji Medical Center in Seoul said, "It becomes hard to get enough vitamin D from sunlight in winter as the amount of sunshine decreases and we cover our body with warm clothes. Vitamin D is stored in the body for about three months, so we should take extra care to get sufficient vitamin D in autumn in preparation for winter."
Getting enough sunshine is the best and easiest way to get vitamin D. When the skin is exposed to ultraviolet B rays in sunlight, cholesterols in the body are turned into vitamin D.
Walking for at least 30 minutes between 11 a.m. and 3 p.m. with arms and legs exposed to the sunlight without applying sun cream is recommended.
