Understand the Health Risks of Hot Weather

Hot weather increases the risk of heat-related health complications such as heat stroke, heat exhaustion, dehydration, hyperthermia, and heat cramps. Those with limited access to cooling, the homeless, the elderly, and children are all at highest risk. Take extra precautions to ensure the safety of yourself and those around you.

Practice Hot Weather Safety

Keep cool and stay safe with these hot weather tips 

• Dress in lightweight, loose-fitting, light-colored clothing. Avoid dark colors like black that absorb sun rays.
• Wear a wide-brimmed, vented hat, or use an umbrella when outdoors.
• Drink plenty of water or sports drink, even if you don't feel thirsty. Avoid alcohol, caffeine, and lots of sugar as they speed up fluid loss.
• Avoid outdoor and strenuous activities between 10 a.m. and 4 p.m. Use a buddy system when working or exercising in excessive heat. Take frequent breaks if you must work outdoors.
• Use air conditioning and remain in cool places during the day. Find a cooling center if you don't have access to air conditioning at home. Palo Alto libraries act as cooling centers in our community during normal business hours. For details see below.
• Never leave people or pets in a closed, parked car.
• Check on your pets frequently and provide them with plenty of water. 
• Minimize direct exposure to the sun. Sunburn reduces your body's ability to dissipate heat. 
• Keep window coverings closed during the day to block the sun's heat. 
• Eat small meals and eat more often. Eat light, cool, easy-to-digest foods such as fruit or salads. 
• Take a cool bath or shower if you feel yourself overheating. Use moist towels to cool down as needed.
• Check on vulnerable family, friends, and neighbors often.
