Don't skip sunscreen over vitamin D fears.

No, but the concern is overblown. Yes, sunscreen blocks UVB rays—the ones that trigger vitamin D production in your skin. But in practice, people don’t apply enough, miss spots, and sweat it off. Your body still gets enough incidental sun exposure to make vitamin D unless you’re a vampire or live in a basement.

The real risk is not enough sun. Vitamin D deficiency is common, but it’s driven by indoor lifestyles, not sunscreen use. A few minutes of sun on your arms and face a few times a week is enough for most people. If you’re worried, eat fatty fish or take a supplement. It’s cheap and reliable.

Meanwhile, skin cancer is a real, well-documented risk. Sunscreen is one of the easiest ways to reduce that risk. Trading a small, manageable vitamin D problem for a real cancer risk is not a smart trade.

Wear sunscreen. Eat some salmon. Done.
