Heat Stroke, Exhaustion a Concern in Hot Weather

It's hot and humid out and with temperatures expecting to hit the low 90's May 31, residents should take care of the possibility of heat stroke or heat exhaustion.

Lt. Larry Grizzell said the fire department hasn’t received heat-related calls yet, but said they are expected.

“It happens every year,” Grizzell said. “Guys, gals get mowing, there’s a lot of sports activity and we get the calls every year.”

Grizzell said the weather Avon Lake has experienced in the past few days—hot with high humidity—is particularly dangerous and people are often unaware heat stroke or heat exhaustion can quickly occur. His main advice? Drink plenty of water.

If heat stroke occurs, the paramedics should be called immediately and the person moved to a cooler environment.

 Excessive heat exposure caused more than 8,000 deaths between 1979 and 2003 in the United States and Fire Capt. Mark Stone shares his tips to staying safe this summer.

"During this period, more people in this country died from extreme heat than from hurricanes, lightning, tornadoes, floods, and earthquakes combined," according to the Centers for Disease Control and Prevention.

"This is the time of year when we (Emergency Medical Services) see a rise in the number of calls we go on," said Stone. "Primarily the reason is because people become more active due to the nicer weather and may not realize their physical limitations."

"With the sudden increase in temperature, such as we are experiencing, our bodies become more stressed since they are not used to this sudden climate change," he said. "The CDC also says, 'Any sudden change in temperature, such as an early summer heat wave, will be stressful to your body. You will have a greater tolerance for heat if you limit your physical activity until you become accustomed to the heat.'"

Bu when temperatures suddenly climb into the 90's, "It can actually take us several days to become acclimated to a new climate," said Stone.

Infants, children and people 65 and older are even more susceptible to the heat changes. 

"Check on the elderly or home-bound in your neighborhood. Frequent checks throughout the day can save a life or prevent a serious medical emergency," said Stone. "Those with heart disease, high blood pressure and certain other illnesses are more at risk in the high temperature extremes as well."

But, heat related deaths and illness are preventable at any age.

Aside from common sense actions, like wearing sunblock, wearing light clothing, drinking water and staying in the shade, Stone says there are more ways to avoid heat related emergencies.

•               Don't drink just anything: Drink plenty of fluids, but avoid coffee, soda (caffeine) and alcohol. Water and sports drinks can replenish your salt and electrolyte loss that happens when we perspire.

•               Enjoy some air conditioning: Air-conditioning is the number one protective factor against heat-related illness and death. Stay indoors if you have a cool environment such as air conditioning, if not, you can go to a shopping mall or . "This short and simple reprieve can help your body stay cooler when you return to the heat," he said.

•               Avoid high noon outdoor plans: Plan your activities around the extremes of the day. If you want to do outdoor activities, try to limit them to the early morning and late evening hours when the temperature and sun is less intense. "Do not mow that lawn today if you can put it off until a cooler day," Stone said. "Taking pride in your lawn and garden should be second to your health."

The following is an excerpt from cdc.gov:

Heat Stroke

Heat stroke occurs when the body is unable to regulate its temperature. The body's temperature rises rapidly, the sweating mechanism fails, and the body is unable to cool down. Warning signs of heat stroke vary but may include the following:

•               An extremely high body temperature (above 103°F, orally)

•               Red, hot, and dry skin (no sweating)

•               Rapid, strong pulse

•               Throbbing headache

•               Dizziness

•               Nausea

•               Confusion

•               Unconsciousness

Heat Exhaustion

Heat exhaustion is a milder form of heat-related illness that can develop after several days of exposure to high temperatures and inadequate or unbalanced replacement of fluids.

Warning signs of heat exhaustion include the following:

•               Heavy sweating

•               Paleness

•               Muscle cramps

•               Tiredness

•               Weakness

•               Dizziness

•               Headache

•               Nausea or vomiting

•               Fainting 

In any of these cases you should seek immediate medical attention by either contacting your doctor or EMS.

"Time is of the utmost importance when dealing with heat related illnesses and emergencies," Stone said.

Temperatures are expected to climb into the  with a UV index of 10, which has potential to match a record high of 92 from 1944.
