As winter sets in, not only does the temperature drop, but the level of Vitamin D in the body also tends to decline rapidly—emerging as a serious health concern today. According to Dr. Sahil, physician at Abrol Hospital (a unit of EMC Hospitals), Vitamin D plays a crucial role not only in strengthening bones but also in boosting the body’s immune system.
During winter, reduced exposure to sunlight and spending most of the time indoors prevents the body from producing adequate natural Vitamin D. This deficiency weakens immunity and increases the risk of infections and other health complications.
Dr. Sahil explains that the early symptoms of Vitamin D deficiency are often overlooked, as they are mistaken for routine fatigue. Common signs include persistent tiredness, muscle and bone pain, joint stiffness, weakness, mood changes, and frequent illnesses. In children, a lack of Vitamin D can hinder proper bone development, while in the elderly it can lead to brittle bones and an increased risk of fractures. The problem is also rising rapidly among women, raising the likelihood of long-term bone-related complications.
If left untreated, Vitamin D deficiency can lead to serious health risks. Prolonged deficiency may cause osteoporosis, joint disorders, muscle weakness, cardiovascular problems, and immune-related diseases. With weakened immunity, the body becomes less capable of fighting infections, increasing both the duration and severity of illnesses.
Experts at Abral Hospital advise that even during winter, people should spend at least 20–30 minutes in sunlight daily, preferably in the morning, as it is most beneficial for the body. In addition, Vitamin D-rich foods such as milk, curd, eggs, fish, and fortified foods should be included in the daily diet. If required, supplements may be taken under medical supervision.
Timely testing, awareness, and a balanced lifestyle can help prevent Vitamin D deficiency during winter and pave the way for a healthier life.
