Keep Cool:

Stay Hydrated:

  • Drink water often, even if you’re not thirsty.
  • Avoid alcohol, caffeine, and sugary drinks.

Check on Others:

  • Call or visit neighbors, friends, and relatives — especially if they live alone or are unhoused.
  • If someone is overheated, dizzy, confused, or unconscious, call 9-1-1 immediately.

Care for Pets:

  • Keep animals in shaded areas with cool water.
  • Avoid walking pets on hot pavement.
  • Never leave animals in parked cars.

Provide Water to Those in Need:

  • If you see someone outdoors in the heat, offer bottled water, sunscreen, or a hat.
  • Outreach providers can request cases of water from ACHCH at (510) 891-8950.

Symptoms of Heat-Related Illness:

  • Body temperature over 103°F
  • Red, hot, dry skin (no sweating)
  • Rapid pulse, dizziness, nausea

If you or someone else shows these symptoms, get medical help immediately.
