I always have queries regarding best time to be under the sun for absorbing Vitamin D in Hyderabad, India. Will walking for 30 minutes late morning around 9-10 will serves the purpose or should I sit under the sun. How much body should I expose to the sun for absorbing Vitamin D. At last, some people even says that exposing our body to Sun will cause skin cancer. What are the best practices for vitamin D and how one can improve vitamin D naturally.
