Yes, you can still tan at 6 pm as long as the sun is out. While the sun's intensity decreases as the day goes on, it can still emit UV rays that cause tanning. However, it is essential to remember that even in the late afternoon, the sun's UV rays can still be harmful to your skin.
It is safest to use sunscreen on exposed skin whenever you go outdoors, even after 5 pm, especially if the sun is visible. Sunscreen protects your skin from the damaging effects of UV rays, which can cause sunburn, premature aging, and skin cancer.
While a tan might seem like a harmless side effect of sun exposure, it's crucial to understand that tanning is your skin's way of protecting itself from damage. Even a slight tan indicates that your skin has been exposed to harmful UV rays, increasing your risk of skin cancer.
Remember, just because the sun isn't as strong in the late afternoon doesn't mean it's safe to skip sunscreen. Applying a broad-spectrum sunscreen with an SPF of 30 or higher will help protect your skin and prevent sun damage.
