The amount of sun exposure that is appropriate for an individual depends on various factors, such as skin type, location, time of day, and season.
However, a general guideline for daily sun exposure to obtain the health benefits of vitamin D without increasing the risk of skin damage or skin cancer is around 10-30 minutes of unprotected sun exposure to the arms, legs, and face, two to three times a week.
Additionally, it is important to avoid direct sun exposure during peak hours, which are typically between 10 am and 4 pm, especially during the summer months when the UV radiation is strongest.
