Importance of Sunlight for Bone Health
Maintaining strong bones is an essential part of a healthy life. One of the most natural ways to support bone strength is through adequate exposure to sunlight, which helps the body produce vitamin D. This vitamin plays a key role in absorbing calcium, the mineral responsible for bone density and strength. During winter, however, many people tend to avoid sunlight, which may lead to a deficiency of vitamin D and related bone problems.
Best Time to Get Sunlight
There is a common belief that early morning or late evening sunlight is ideal for health. In reality, the most effective time for the body to produce vitamin D is between 10 a.m. and 3 p.m. During this period, the sun’s rays are at the right angle to stimulate vitamin D production in the skin. Exposing around 20 percent of the body—such as arms and legs—for about 15 minutes daily is generally considered sufficient. It is important to note that sunscreen or lotions should not be applied during this short exposure, as they block the rays needed for vitamin D synthesis.
Challenges During Winter
In large urban areas, especially during winter months, air pollution often reduces the amount of sunlight that reaches the ground. As a result, people may not receive enough vitamin D even when outdoors. This makes vitamin D deficiency quite common during colder seasons. To compensate, individuals can include vitamin D–rich foods such as milk, curd, cheese, fortified cereals, and eggs in their daily diet.
Women and Bone Health
Women are particularly vulnerable to bone-related conditions such as osteoporosis and osteomalacia, especially before and after menopause. Hormonal changes during these phases can weaken bones over time. Women who cover most of their body with clothing or regularly use sunscreen may also have lower vitamin D levels because sunlight does not reach their skin adequately. Paying attention to diet, sunlight exposure, and regular health check-ups is therefore especially important for them.
Vitamin D and Children
Children also require sufficient vitamin D for proper growth and bone development. A deficiency at a young age can lead to rickets, a condition that causes weak and deformed bones. Children who have stopped breastfeeding should be given a balanced diet that includes foods rich in vitamin D and calcium. Along with proper nutrition, allowing children to spend time in natural sunlight helps ensure healthy bone development from an early age.
Role of Exercise in Winter
Along with sunlight and nutrition, regular physical activity supports bone health. Weight-bearing exercises such as walking, light jogging, yoga, or strength training help maintain bone density. Staying active during winter may feel challenging, but even moderate daily exercise can reduce the risk of bone thinning and joint problems in the long run.
