Do you know?
Vitamin D is made in our body when sunlight hits the skin. It keeps our bones strong and helps us stay healthy.
Sunlight triggers vitamin D
When ultraviolet B (UVB) rays from the sun hit the skin, they trigger a process that converts cholesterol into vitamin D, essential for health. Sunlight helps our skin make vitamin D naturally.
Essential for bone health
Vitamin D helps your body absorb calcium, which strengthens bones and prevents conditions like rickets in children and osteoporosis in older adults. It keeps our bones strong and healthy.
Supports immune function
Vitamin D plays a vital role in maintaining a strong immune system, helping your body fight infections and reducing the risk of chronic diseases. It helps the body stay protected from sickness.
Mood and mental health
Adequate vitamin D levels are linked to better mood and reduced risk of depression, especially in people who get little sunlight in colder months. Vitamin D can help you feel happier.
Best time for sunlight exposure
The best time to get sunlight for vitamin D is midday, when UVB rays are strongest. Short exposure is usually enough for most people. Midday sun is best for vitamin D.
Skin tone affects production
Darker skin has more melanin, which reduces vitamin D production. People with darker skin may need longer sun exposure to produce adequate levels. Darker skin needs more time in the sun.
