Resources and tips
Staying safe in the heat
- Don't wait until you're thirsty to drink water or electrolyte-replacements
- Drink cool water, not extremely cold water (which can cause cramps)
- Avoid sweetened drinks, caffeine, and alcohol
Protect a pet from excessive heat
- Never leave a pet or animal in a garage
- Never leave a pet or animal in a vehicle
- Never leave a pet or animal in the sun
- Provide shade
- Provide clean drinking water
Protect a human from excessive heat
Check in frequently with family, friends, and neighbors. Offer assistance or rides to those who are sick or have limited access to transportation. And give extra attention to people most at risk, including:
- Elderly people (65 years and older)
- Infants
- Young children
- People with chronic medical conditions
- People with mental illness
- People taking certain medications (i.e.: "If your doctor generally limits the amount of fluid you drink or has you on water pills, ask how much you should drink while the weather is hot," says the CDC)
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
