Afternoon Sun Boosts Bone Health More Than Morning
18 Nov
Summary
- Afternoon sunlight is more effective for vitamin D production.
- Vitamin D is crucial for calcium absorption and bone strength.
- Deficiency can lead to osteoporosis and osteomalacia in all ages.
The common belief that early morning sunlight is sufficient for bone health and vitamin D levels is being challenged by experts. Research indicates that afternoon sunlight, specifically between 12 p.m. and 3 p.m., offers the most beneficial UVB rays for vitamin D synthesis. This vitamin is vital for calcium absorption, which is essential for maintaining strong bones.
Vitamin D deficiency can lead to significant bone health issues, including osteoporosis in older adults and osteomalacia in younger individuals. Factors such as sedentary lifestyles, indoor living, and poor dietary habits contribute to this deficiency, even among young adults. The body requires unprotected sun exposure for about 20-30 minutes, two to three times a week, to achieve healthy vitamin D levels.
While supplements are available, self-medication is discouraged. It is recommended to get tested and consult a healthcare professional for appropriate supplementation. Prioritizing brief, safe exposure to afternoon sun, alongside a balanced diet and regular exercise, is the most reliable way to support bone health and prevent premature wear and tear.
