Extreme Heat

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.

Heat is one of the leading weather-related killers in the United States, resulting in over one thousand fatalities each year, per the CDC. Heat can be very taxing on the body; check out the heat related illnesses that can occur with even a short period of exposure. Everyone can be vulnerable to heat, but some more so than others. According to The Impacts Of Climate Change On Human Health In The United States: A Scientific Assessment the following groups are particularly vulnerable to heat; check in with friends and relatives who fall in one of these populations, especially if they don’t have air conditioning.

• Young children and infants are particularly vulnerable to heat-related illness and death, as their bodies are less able to adapt to heat than are adults. 
• Older adults, particularly those with pre-existing diseases, take certain medications, are living alone or with limited mobility who are exposed to extreme heat can experience multiple adverse effects.
• People with chronic medical conditions are more likely to have a serious health problem during a heat wave than healthy people.
• Pregnant women are also at higher risk. Extreme heat events have been associated with adverse birth outcomes such as low birth weight, preterm birth, and infant mortality, as well as congenital cataracts.

Plan Ahead 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.
• 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.

Tips to Stay Cool

• 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, 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.

How to Recognize Heat Related Illness

During extremely hot and humid weather, your body's ability to cool itself is challenged. When the body heats too rapidly to cool itself properly, or when too much fluid or salt is lost through dehydration or sweating, body temperature rises and you or someone you care about may experience a heat-related illness. It is important to know the symptoms of excessive heat exposure and the appropriate ways to respond.

Heat Cramps may be the first sign of heat-related illness, and may lead to heat exhaustion or stroke.

• Symptoms: Painful muscle cramps and spasms usually in legs and abdomen and Heavy sweating.
• First Aid: Apply firm pressure on cramping muscles or gently massage to relieve spasm. Give sips of water unless the person complains of nausea, then stop giving water. 

Heat Exhaustion 

• Symptoms: Heavy sweating, Weakness or tiredness, cool, pale, clammy skin; fast, weak pulse, muscle cramps, dizziness, nausea or vomiting, headache, fainting,
• First Aid: Move person to a cooler environment, preferably a well air conditioned room. Loosen clothing. Apply cool, wet cloths or have person sit in a cool bath. Offer sips of water. If person vomits more than once,

Heat Stroke

• Symptoms: Throbbing headache, confusion, nausea, dizziness, body temperature above 103°F, hot, red, dry or damp skin, rapid and strong pulse, fainting, loss of consciousness.
• First Aid: Call 911 or get the victim to a hospital immediately. Heat stroke is a severe medical emergency. Delay can be fatal. Move the victim to a cooler, preferably air-conditioned, environment. Reduce body temperature with cool cloths or bath. Use fan if heat index temperatures are below the high 90s. A fan can make you hotter at higher temperatures. Do NOT give fluids.

While the kids are home for the summer, get the whole family prepared for the summer and all year round.
