Thing you can do:
- Bring a bottle of water. Refill it if needed between classes.
- Dress in layers. If you wear a sweatshirt or sweater, wear something underneath that you don't mind showing.
- Do bring a jacket in case the air conditioning gets carried away.
- Realize that some schools don't have air conditioning at all -- ever!
- Think how much hotter you'd be if you lived in Arizona or Afghanistan or the Sahara Desert.
- Picture yourself with Shackleton and his crew on their Antarctic Expedition.
- Think how great it is that it's almost summer vacation!
