Is it normal to hate the sun?
Mostly.Normal for most people
Yes, it’s normal to dislike the sun. Plenty of people would rather skip the glare, heat, sweating, and sunburn risk.
You’re not required to be a sunshine person. Some people love bright, warm days; others find the glare irritating, the heat exhausting, or the whole sunscreen-and-sweating situation deeply unappealing. Both are ordinary preferences.
If you mean sunlight actually hurts your eyes or gives you severe headaches, that’s more than just disliking sunny weather and could be worth getting checked. Otherwise, you’re allowed to be on Team Shade.
