Be Ready for Summer! Adapted from www.ready.gov/heat
There is hot, and then there is hot! Orange County has already experienced a string of heat waves, with plenty of summer still on the way. Just like any other weather event, it’s important to be prepared for extreme heat before it arrives. 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 people with certain illnesses and chronic conditions are at greater risk from extreme 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 cooling options in your area. Cover windows with drapes or shades. Weather-strip doors and windows. Use window reflectors specifically designed to reflect heat back outside. Add insulation 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. If you are unable to afford your cooling costs, weatherization or energy-related home repairs, contact the Low Income Home Energy Assistance Program (LIHEAP) for help.
Be Safe During Extreme Heat Never leave people or pets in a closed car on a warm day. If air conditioning is not available in your home find a cooling option. 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, older adults 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. Heat waves may cause you to lose power. Visit Power Outages to learn how to stay safe.
