Vitamin D is an essential vitamin that plays a vital role in maintaining the body's overall health and regulating calcium absorption. It is essential for strong bones and a healthy immune system for both adults and children. Vitamin D deficiency has become increasingly common, especially with modern lifestyles, such as long periods indoors and insufficient exposure to sunlight. This can have negative effects in many areas, from bone health to the immune system. So, what role does sunlight play in addressing this deficiency?
The sun is our natural source of vitamin D. Our skin produces vitamin D when exposed to the sun's UVB rays. This process allows the body to utilize active vitamin D, which is essential for healthy bone development and immune function. However, the effectiveness of sunlight varies depending on age, skin color, geographical location, season and daily living habits. Especially for children and adults, these variables may require different strategies to prevent vitamin D deficiency.
Children need more vitamin D because they are in a period of growth and development. Getting enough vitamin D from the sun supports their bone health and strengthens their immune system. Adults, on the other hand, need to maintain adequate levels of vitamin D to maintain bone density and avoid diseases such as osteoporosis. However, direct and continuous exposure to sunlight may not always be possible or may increase the risk of skin cancer.
In this article, we will discuss the role of sunlight in addressing vitamin D deficiency, separately for children and adults. For both groups, we will provide comprehensive information on sun exposure, sun exposure duration, cautions and alternative sources of vitamin D. Our aim is to provide both children and adults with the right information to maintain healthy vitamin D levels.
Sunbathing Vitamin D Intake for Adults
- UVB Rays: The sun's UVB rays initiate vitamin D synthesis in the skin. This process converts 7-dehydrocholesterol on the surface of the skin into vitamin D3.
- Duration and Time: It is usually sufficient for adults to expose large areas of skin, such as the face, arms and legs, to sunlight for between 10-30 minutes, several times a week. This may vary depending on skin type and geographical location. People with fair skin can get enough vitamin D in shorter periods, while those with darker skin may need to sunbathe for longer.
Things to Consider
- Sunscreen Use: Sunscreens can reduce vitamin D synthesis by blocking UVB rays. Therefore, short periods of sunbathing without sunscreen may be necessary for vitamin D synthesis. However, prolonged sunbathing increases the risk of skin cancer, so care should be taken.
- Season and Geographical Location: During winter and at high latitudes, it can be difficult to get enough vitamin D from sunlight. During these periods, vitamin D supplements may be needed.
- Lifestyle: People who work indoors or spend little time outdoors may be at risk of vitamin D deficiency. In this case, vitamin D intake should be supported by diet and supplements.

Sunbathing Vitamin D for Children
- UVB Rays: Children can also synthesize vitamin D thanks to the UVB rays of sunlight. This is particularly important for the health of growing bones.
- Duration and Time: It is usually sufficient for children to be exposed to sunlight for 10-15 minutes, several times a week. Since babies' skin is more sensitive, it is important to start with very short periods and increase gradually.
Things to be aware of
- Skin Sensitivity: Since children have more sensitive skin, care should be taken to protect them from sunburn. Sunscreens should be used, but sunbathing without sunscreen can be provided at certain intervals for vitamin D synthesis during short-term sunbathing.
- Season and Geographical Location: During the winter months and in areas with little sunlight, it may be difficult for children to get enough vitamin D. During these periods, vitamin D drops or other supplements can be used on doctor's advice.
- Infants and Young Children: Direct sun exposure is not recommended for infants. Therefore, it is important for breastfeeding mothers to have high vitamin D levels. In addition, vitamin D supplements can be used for infants on doctor's advice.
