It depends on the situation and your individual risk factors. While some sun exposure is beneficial for vitamin D production, prolonged sun exposure without protection can lead to sunburn and increase your risk of skin cancer.
Factors to consider:
- Duration of exposure: Brief periods of sun exposure (5–15 minutes, 2–3 times a week) with uncovered face, arms, or legs can provide vitamin D benefits without significant risk.
- Intensity of sunlight: UV rays can penetrate clouds, so even on cloudy days, sun protection is essential.
- Skin type: People with fair skin, freckles, and a family history of skin cancer are more susceptible to sun damage.
- Location and time of day: Sunlight is strongest between 10 am and 4 pm.
General recommendations:
- Limit prolonged sun exposure: Avoid spending extended periods in direct sunlight, especially during peak hours.
- Wear protective clothing: Cover up with long sleeves, pants, and a wide-brimmed hat.
- Apply sunscreen: Use a broad-spectrum sunscreen with an SPF of 30 or higher.
In summary:
You can go without sunscreen for short periods of sun exposure, but it's generally advisable to protect your skin from harmful UV rays.
