Researchers from the National Institute of Dance Medicine and Science, UK, have been amongst the growing number of health professionals to voice concerns for dancers and other athletes who consistently train in-doors and may be missing out on the necessary intake of vitamin D. The skin's exposure to sunlight allows Vitamin D to form in the body, which is an important factor in preventing serious bone diseases such as osteoporosis, rickets, or scoliosis, all of which present major problems for athletes, who place great stress on their bones and joints. Vitamin D is also essential in maintaining calcium and phosphate homeostasis within the body, supporting immune function and allowing for optimum physical performance. It is estimated that over 1 billion people worldwide are vitamin D deficient.
To make sure you're not lacking this essential vitamin and putting yourself at risk, aim to get sun exposure between 5-20 minutes on the face, arms, back or legs twice a week. Alternatively if you think your schedule doesn't allow for this (often dancers at full-time schools/companies start early in the morning and finish late in the afternoon/evening, which makes things tricky!) then Vitamin D supplements can be taken.
Make sure you're maintaining your body at optimum health to allow you to perform to your full capacity ...healthy dancers are happy dancers! ;)
