Summer heat brings health cautions
Children and pets left unattended in vehicles as outside temperatures rise aren’t the only potential victims of heat-related death – so are the elderly, those with extenuating health conditions and people who work or recreate outside for long periods of time.
The National Weather Service reports that heat is the number one weather-related killer in the U.S. On average, excessive heat claims more lives each year than floods, lightning strikes, tornadoes and hurricanes combined.
More than 1,250 people died during the tragic heat wave of 1980. In 1995, more than 700 deaths in the Chicago area were attributed to heat, and in August 2003, a record heat wave in Europe claimed an estimated 50,000 lives.
“North American summers are hot; most summers see heat waves in one or more parts of the United States. East of the Rockies, they tend to combine both high temperature and high humidity; although some of the worst heat waves have been catastrophically dry,” the weather service reports.

The hazards of excessive heat
Studies indicate that, other things being equal, the severity of heat disorders tends to increase with age. Conditions that cause heat cramps in a 17-year-old may result in heat exhaustion in someone 40 years old, and in heat stroke in a person over 60.
Sunburn, with its ultraviolet radiation burns, can significantly retard the skin's ability to shed excess heat. Acclimatization has to do with adjusting sweat-salt concentrations, among other things. The idea is to lose enough water to regulate body temperature, with the least possible chemical disturbance – salt depletion.
Children, adults and pets enclosed in parked vehicles are at great risk
Each year, dozens of children left in parked vehicles die from hyperthermia.
Hyperthermia is an acute condition that occurs when the body absorbs more heat than it can handle. Hyperthermia can occur even on a mild day. Studies have shown that the temperature inside a parked vehicle can rapidly rise to a dangerous level for children, pets and even adults. Leaving the windows slightly open does not significantly decrease the heating rate. The effects can be more severe on children because their bodies warm at a faster rate than adults.
"But it's a dry heat..."
Sun burn: Redness and pain. In severe cases swelling of skin, blisters, fever, headaches.
Heat cramps: Painful spasms usually in muscles of legs and abdomen possible. Heavy sweating.
Heat exhaustion: Heavy sweating, weakness, skin cold, pale and clammy. Pulse thready (scarcely perceptible). Normal temperature possible. Fainting and vomiting.
Heat stroke (or sunstroke): High body temperature (106° F. or higher). Hot dry skin. Rapid and strong pulse. Possible unconsciousness.
Heat stress safety:
Take advantage of air conditioning when possible. Many homes in New Mexico still use evaporative cooling (swamp coolers), which are much less effective during the monsoon.
If you, or someone you're with, begins to feel tired and flushed and begin to sweat excessively, it might indicate heat exhaustion. Stop any strenuous activities immediately, drink more water and find a cool place to rest.
If someone becomes disoriented, stops sweating, has hot dry skin, or even worse, passes out, that person is probably experiencing heat stroke – a serious medical condition. Call 9-1-1 immediately! If possible, move them to a cooler location.
Provide plenty of water and shade for pets.
