Extreme Heat

California has experienced a rise in temperatures over the past several decades. Extreme heat means at least two to three days of high heat and humidity, with temperatures above 90 degrees. 

• Plan ahead and check the weather forecast to prepare for hot days.
• Reduce your time outside in the direct heat.
• Stay hydrated.
• Have a buddy system. Work with family, friends or neighbors to check on those considered at risk during extreme heat.  
• Prepare for power outages during heat events.

Prepare your home

• Close shades, blinds, or curtains to block out sun.  
• Insulate or weatherstrip windows and doors.  
• If using window air conditioner, insulate around it.  

• Stay indoors as much as possible; limit sun exposure.
• Draw curtains over windows to limit direct sunlight indoors.
• Take cool showers and use damp cloths around your shoulders to reduce body heat.
• Stay hydrated. Drink more fluids than usual, even if you don’t feel thirsty.  
• Avoid drinks with alcohol or caffeine: they increase the heat’s effects on your body.
• Limit activity and avoid being outdoors during the hottest parts of the day.
• Wear lightweight, loose-fitting, light-colored clothing; wear hats, use sunscreen  
• Never leave people or pets in closed vehicles, even for short periods
• If needed, go to a cool place such as a mall or library for relief from heat.
• Check on others: neighbors, friends or family, especially those at higher risk.  
• Monitor local news for the latest information on the weather forecast.
• Extreme heat can exacerbate the power grid and cause a power outage. Be prepared with enough supplies for 3-5 days.  

In extreme heat your body works extra hard to maintain a normal temperature, which can lead to serious health implications. Take the necessary precautions to avoid heat-related illnesses.

Heat Cramps are the least severe. They are often the first signal that the body is having trouble with the heat. Symptoms include painful cramps, especially in the legs, and flushed, moist skin.

Heat Exhaustion signs include extreme weakness, thirst, muscle cramps, nausea or headache, and heavy sweating.

Heat Stroke can start rapidly. Serious symptoms can occur within minutes and can include dry red skin, convulsions, disorientation, delirium, and coma. Keep heat stroke victims in a cool area and call 911 immediately.

Those especially at risk include:  

• Older adults (65+)  
• Infants, young children  
• People with chronic medical conditions (heart disease, respiratory conditions, kidney disease, etc.)  
• Those taking medications that affect body temperature regulation  
• People without access to air conditioning or cooling spaces  
• Pets and animals
