It is believed that vitamin D plays a role in the production of serotonin, a neurotransmitter that regulates mood. By ensuring you have adequate levels of vitamin D, you may be able to support your mental health and improve your overall mood.
Vitamin D and cancer prevention
Emerging evidence suggests that vitamin D may even play a role in preventing certain types of cancer. Research has shown that maintaining optimal levels of vitamin D can help reduce the risk of developing breast, colon, and prostate cancers. Although more studies are needed to fully understand the relationship between vitamin D and cancer prevention, early findings are promising and highlight the importance of including sufficient vitamin D in your daily routine.
Sources of Vitamin D
Sun exposure
The sun is a primary source of vitamin D. When your skin is exposed to sunlight, it produces vitamin D through a series of chemical reactions. However, it is important to note that the amount of vitamin D produced depends on factors like the time of day, season, skin color, and the amount of skin exposed. It is generally recommended that you have 10 to 30 minutes of sun exposure on your face, arms, and legs, two to three times a week, during the peak sunlight hours (between 10 am and 3 pm) to maintain vitamin D levels.
Dietary sources
While sun exposure is a significant source of vitamin D, it can also be obtained through certain dietary sources. Fatty fish like salmon, mackerel, and sardines are excellent natural sources of vitamin D. Other foods such as egg yolks, fortified dairy products, and fortified cereals also contain some amount of vitamin D. However, it can be challenging to meet your daily vitamin D requirements through diet alone, particularly for individuals with limited sun exposure.

Understanding Sun Exposure
UV radiation and its effects
When discussing sun exposure, it is important to understand the role of UV (ultraviolet) radiation. The sun emits three types of UV radiation: UVA, UVB, and UVC. UVA rays penetrate the skin deeply, affecting its elasticity and contributing to premature aging. UVB rays are responsible for skin reddening and sunburn, but they also trigger vitamin D production. UVC rays are the most harmful, but fortunately, they are absorbed by the Earth’s atmosphere and do not reach our skin.
Factors influencing vitamin D production
Several factors can influence the amount of vitamin D produced by your skin when exposed to sunlight. The angle of the sun’s rays, which is affected by the time of day and season, plays a role in the intensity of UVB radiation and, consequently, the amount of vitamin D synthesized. Additionally, your skin color can impact vitamin D production since individuals with darker skin require more prolonged sun exposure to produce the same amount of vitamin D as those with lighter skin.
Recommended sun exposure time
Achieving optimal vitamin D levels through sun exposure requires finding the right balance. It is crucial to prioritize skin safety and minimize the risk of sunburn and skin damage. The Skin Cancer Foundation recommends that you expose your skin to the sun for a short time, depending on your skin type and the UV index. Generally, spending 10 to 30 minutes in the sun, two to three times a week, on the face, arms, and legs, during the peak sunlight hours, is sufficient for most individuals to maintain healthy vitamin D levels.
Optimizing Vitamin D Absorption

Sunscreen is essential for protecting your skin from harmful UV rays and reducing the risk of sunburn and skin cancer. However, it is important to note that the use of sunscreen can significantly reduce vitamin D absorption. Most sunscreens with adequate sun protection factor (SPF) of 30 or higher can block up to 97% of UVB rays, limiting the skin’s ability to produce vitamin D. While it is crucial to prioritize sun protection, finding a balance between sunscreen use and vitamin D absorption is necessary for overall health.
Balancing risk of sunburn and vitamin D production
Finding the right balance between sun exposure for vitamin D production and minimizing the risk of sunburn is crucial. It is recommended to limit prolonged sun exposure when the UV index is high, particularly during midday when the sun’s rays are the strongest. Instead, aim for shorter periods of sun exposure during the morning or late afternoon when UV radiation is less intense. This approach helps minimize the risk of sunburn while still allowing your body to produce sufficient vitamin D.
Clothing and sun exposure
The clothing you wear can significantly impact the amount of skin exposed to sunlight and, consequently, the production of vitamin D. When spending time outdoors, wearing loose, lightweight clothing that covers your skin can provide protection from harmful UV rays while allowing some sun exposure. However, it is important to note that clothing can reduce the skin’s ability to produce vitamin D. To optimize vitamin D absorption, try to expose areas of the body like the face, arms, and legs while keeping the rest covered and protected.
