At this time, the sun is at its highest point, and UVB rays, which are responsible for vitamin D production, are strongest. For most people, adequate vitamin D levels are reached through regular incidental exposure to the sun.
Around 10-30 minutes of sun exposure is generally enough for most skin types, depending on skin tone, location, and time of year.
To produce vitamin D effectively, it's best to allow your skin to be exposed to sunlight without sunscreen for a short period.
Exposing larger areas of skin, such as arms, legs, or back, increases vitamin D synthesis. Even short bursts of exposure in these areas can help meet daily requirements.
Darker skin produces less vitamin D compared to lighter skin because it has more melanin. Older adults also tend to produce less vitamin D, so they may need more sun exposure to meet their needs.
