Best Times of Day to Avoid UV Radiation

Spending time outside is one of the great things about a sunny day. Whether you're walking the dog, working in the garden, or just enjoying a bit of fresh air, sunshine can lift your mood. But while some sun is good, too much exposure to UV (ultraviolet) rays can be harmful to your skin.

UV rays from the sun are strongest during certain times of the day. Keeping this in mind can help you protect your skin and reduce the risk of sunburn or long-term damage. It's also helpful to check today’s UV index on a weather app or website—it’ll give you a good idea of how strong the sun’s rays are expected to be that day.

Generally, UV radiation from the sun is strongest between 10 AM and 4 PM. This is the time when the sun is highest in the sky and the rays have the shortest path to reach us. If you're outside during these peak hours, you're getting the most direct exposure.

To reduce your exposure, try to plan outdoor activities in the early morning or later in the afternoon. Before 10 AM and after 4 PM, the sun is lower in the sky, and the UV rays are weaker. This makes these times safer for being outside, especially if you’re going to be out for more than a few minutes.

Of course, life is busy and sometimes being outside during peak sun hours is hard to avoid. In those cases, you can still protect your skin by wearing a hat, long sleeves, and using sunscreen with SPF 30 or higher. Also, look for shade whenever possible, like under a tree or an umbrella.

It's easy to forget how powerful the sun can be, especially on cooler or cloudy days. But UV rays can still reach your skin even when it's not super hot or the sun isn’t blazing. So, being aware of the time and making small adjustments to your routine can make a big difference.

In short, aim for morning or late afternoon if you're planning time outside. Your skin will thank you for it!
