I always hear that we should avoid the sun or make sure to put on sunscreen in the afternoon when the sun is the most intense. Why is the sun’s rays more harmful when it is directly overhead vs in the morning soon after sunrise? Either way, the sun is shining directly on me so not sure what causes the difference in intensity.

You’re forgetting there’s the air between you and the Sun. Sure it’s mostly transparent, but there are many kilometers of it. And when the sunlight goes through it at an angle the range it has to travel through air increases more.
