By age 70, the body’s thermoregulatory control diminishes. Sweat glands decrease function, less body fat insulates less, circulation decreases, and the brain has a tougher time responding. Older people, therefore, need to be aware of other symptoms when considering health conditions. Hot or cold skin temperature, dehydration, altered mental status, low blood pressure, fast pulse, and rapid breathing rates are all telltale signs of illness or injury. With subtle symptoms, it’s recommended you call or visit your doctor. More pronounced symptoms are cause for calling 911.
