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

Things to do

The work week is almost over! If you're looking for ways to explore more of the rich and diverse, artistic community in L.A., then check this out.

  • The Living Queer Archive at LACE : LACE (Los Angeles Contemporary Exhibitions) gallery has served as an incubator for queer artistic experimentation in L.A. since its founding in 1978. The organization's living queer archive highlights moments of "queer cultural production" in LACE’s exhibition and programming history. This event brings together artists, curators and creatives who have contributed to this archive, with panelists — artist Cat Jones, activist artist and educator Jerri Allyn and writer, artist, and critic Matias Viegener — talking about the archive as well as the present and future of L.A.'s queer art scene. The discussion will be moderated by LACE’s Assistant Director of Programming Juan Silverio.

    The Living Queer Archive at LACE panel discussion is part of ONE Archives’ Circa Festival. To learn more about the festival and see program listings, visit the Circa Festival website.
