Living through a hot summer seems impossible but, hey, our grandparents did it all the time! Turns out, they learned a few things in the process. Here are 10th tried-and-true DIY strategies help to stay cool in summer.

1. Choose cotton.
Save the ooh-la-la satin, silk, or polyester sheets for cooler nights. Light-colored bed linens made of lightweight cotton (Egyptian or otherwise) are breathable and excellent for promoting ventilation and airflow in the bedroom.
2. Feel the freezer burn.
Stick sheets in the fridge or freezer for a few minutes before bed. We recommend placing them in a plastic bag first (unless eu de frozen pizza is your fave aromatherapy scent).
3. Get cold comfort.
Here’s a four-seasons tip for keeping utilities charges down: Buy a hot water bottle. In winter, fill it with boiling water for toasty toes without cranking the thermostat. During summer, stick it in the freezer to create a bed-friendly ice pack.
4. Be creative.
If you thought fans are just for blowing hot air around, think again! Point box fans out the windows so they push hot air out, and adjust ceiling fan settings so the blades run counter-clockwise, pulling hot air up and out instead of just twirling it around the room.
5. Sleep like an Egyptian.
If there seem to be a lot of Egyptian references in this list, it’s because those Nile-dwellers knew how to do it right. The so-called “Egyptian method” involves dampening a sheet or towel in cool water and using it as a blanket. We recommend laying the damp sheets on top of a dry towel to avoid soaking the mattress.
6. Get loose.
Less is definitely more when it comes to summertime jammies. Pick a loose, soft cotton shirt and shorts or underwear.
7. Go old-school.
Remember when refrigerators were iceboxes that contained actual blocks of ice? Us neither. This stay-cool trick is straight out of the icebox era, though. Make a DIY air conditioner by positioning a shallow pan or bowl (a roasting pan works nicely) full of ice in front of a fan. The breeze will pick up cold water from the ice’s surface as it melts, creating a cooling mist
8. Create a cross-breeze.
In this case, hanging out in the cross-hairs is a good idea. Position a fan across from a window, so the wind from outside and the fan combine in a cooling cross-breeze. Feeling fancy? Go buck-wild and set up multiple fans throughout the room to make the airflow even more boisterous.
9. Pamper your pulses.
Need to cool down, stat? To chill out super fast, apply ice packs or cold compresses to pulse points at the wrists, neck, elbows, groin, ankles, and behind the knees.
10. Get tech-y.
We can’t vouch for its effectiveness, but the chillow—a high-tech pad that stays cool through water circulation—seems like a genius idea.
