Sun protection that actually works. The five-minute version
Applies to: Skin
Skin cancer is one of the most preventable cancers there is, and most of the protection that matters takes about five minutes a day.
Full guide
The five minutes that matter
Broad-spectrum SPF 30+, applied daily, not just at the beach. Most sun damage happens during ordinary days: driving, walking, standing in a parking lot. Reapply every two hours outdoors, and immediately after swimming or heavy sweating. A daily habit beats an occasional heavy application.
The clothing shortcut
UPF-rated clothing, a wide-brim hat, and sunglasses with UV protection do more consistent work than sunscreen alone, because you cannot forget to reapply fabric. If you are outside for hours, clothing is the more reliable layer.
The one non-negotiable
There is no safe amount of tanning bed use. Tanning beds are a well-established melanoma risk multiplier, and the risk is highest for use before age 35. If you use one now, stopping is the single highest-leverage change available to you.
Timing matters more than people think
UV is strongest from 10am to 4pm. Seeking shade or planning outdoor time around that window meaningfully cuts your exposure without asking you to give up being outside.
What to still watch for
Sun protection lowers risk. It does not eliminate it. Keep doing a monthly self-check using the ABCDE rule (asymmetry, border, color, diameter, evolution).
