Tips to stay cool

  • Kiddie pool
  • Lotions in the fridge
  • Eat spicy foods in the basement (or on the floor) while wearing a damp shirt and listening to the rain setting on your white noise machine
  • Make sure ceiling fans are running counterclockwise
  • Wet paper towels. Fold into ankle and wrist cuffs. Freeze. Wear. Repeat.
  • Build a DIY AC
  • Build a mini cold air fan
  • Build an "evaporative cooler for immediate heat relief"
  • Make a barricade of fans and ice cubes
  • Go to an air-conditioned store and browse for as long as possible (Target is a good option for this).
  • Close all the curtains, preferably the heat-absorbing kind
  • Or open all the windows, depending on the breeze situation
  • Cool bath or shower twice a day
  • Wash your sheets before bed but don't dry them — put them on your bed damp (provided you're dealing with a dry heat)
  • Portable A/C unit
