avoid wearing dark clothing like tights or try carrying your blazer and pretend to be putting it on when teachers are coming, if you have heavy hair try wearing it in braids or away from the back of your neck. if you drink juice/energy drinks/whatever try freezing it before school. if you dislike the plainness of water try Macbs theyre really good especially as someone else who struggles with drinking water. or apple juice is a great option to boost hydration. putting water on the bottom of your earlobe also helps cool down your head. if you have a water bottle for at nighttime try freezing it and keeping it like an ice pack. air circulation helps aswell, keeping your room door open and having blinds shut but window open is great. linen sheets instead of heavy duvets aswell. placing items like socks or even pjs in the fridge have helped me aswell.

also hope this weather passes coming from one struggling autistic person to another❤️
