Amid lockdown due to coronavirus epidemic, many of us are not getting adequate sunlight exposure. It is important to note that sunlight, which comes through your window, can not help in producing vitamin D since ultraviolet B rays are filtered by glass.Our immunity plays a very important role in fighting viral diseases such as coronavirus, and vitamin D is one of the very important vitamin that helps in immunoregulation, said Dr Ravi Shekhar Jha, senior consultant and Head of the Department, Pulmonology, Fortis Escorts Faridabad, India.
How does one get vitamin D?
As a fat-soluble vitamin, it is produced internally when ultraviolet rays from the sunlight hit the skin and initiate the process of vitamin D synthesis. Since it is present in very few foods, people are mainly dependent on sunlight exposure to get adequate vitamin D. Dark-skinned people need longer time in sunlight to make the same amount of vitamin D than light-skinned people, mentions Dr Jha.
How does Vitamin D help?
Vitamin D is essential for regulating calcium and phosphate in your body. Besides bone growth, vitamin D also regulates cell growth, immune function, neuromuscular function, and suppression of inflammation.
Sources of adequate levels of vitamin DTry taking foods which are rich in vitamin D, like oily fish liek salmon, and eggs and red meats. Also, it is good idea to go to your terrace or roof for few minutes with maximum part of your body exposed to direct sunlight. Under doctor’s supervision, you can also take vitamin D supplements, however, we must remember that vitamin D is a fat-soluble vitamin, and any excess stored in the body can be toxic. So, it should not be taken without prescription, Dr Jha said.
