There is hot, and then there is hot! Extreme heat is a period of high heat and humidity with temperatures above 90 degrees for at least two to three days. In extreme heat your body works extra hard to maintain a normal temperature, which can lead to death. Extreme heat is responsible for the highest number of annual deaths among all weather-related hazards.

Older adults, children and sick or overweight individuals are at greater risk from extreme heat.

Humidity increases the feeling of heat.

Prepare for Extreme Heat

• Learn to recognize the signs of heat illness.
• Do not rely on a fan as your primary cooling device. Fans create air flow and a false sense of comfort, but do not reduce body temperature or prevent heat-related illnesses. 
• Identify places in your community where you can go to get cool such as libraries and shopping malls or contact your local health department to find a cooling center in your area.
  • Check Out Edsel T Ford Center 10 Pitkin St, Highland Park, MI 48203

• Cover windows with drapes or shades.
• Weather-strip doors and windows.
• Use window reflectors specifically designed to reflect heat back outside.
• Added insulation helps to keep the heat out.
• Use a powered attic ventilator, or attic fan, to regulate the heat level of a building’s attic by clearing out hot air.
• Install window air conditioners and insulate around them.

Be Safe DURING

• Never leave people or pets in a closed car on a warm day.
• If air conditioning is not available in your home go to a cooling center.
• Take cool showers or baths.

• Wear loose, lightweight, light-colored clothing.
• Use your oven less to help reduce the temperature in your home.
• If you’re outside, find shade. Wear a hat wide enough to protect your face. 
• Drink plenty of fluids to stay hydrated.
• Avoid high-energy activities or work outdoors, during midday heat, if possible.
• Check on family members, seniors and neighbors.
• Watch for heat cramps, heat exhaustion and heat stroke.
• Consider pet safety. If they are outside, make sure they have plenty of cool water and access to comfortable shade. Asphalt and dark pavement can be very hot to your pet’s feet.
• If using a mask, use one that is made of breathable fabric, such as cotton, instead of polyester. Don’t wear a mask if you feel yourself overheating or have trouble breathing.
