With temperatures forecast to stay around 100 for the next few days, Carthage residents need to be careful when working outside.
The National Weather Service says heat is the number one weather-related killer in the United States, resulting in hundreds of fatalities a year. On average, excessive heat claims more lives annually than floods, lightning, tornadoes and hurricanes combined.
When the body heats too quickly to cool itself safely, or when you lose too much fluid or salt through dehydration or sweating, your body temperature rises and heat-related illness may develop.
Heat disorders share one common feature: the individual has been in the heat too long or exercised too much for his or her age and physical condition.
Studies indicate that 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.
