Alzheimer’s caregivers should take precaution about temperatures, heat and cold. Alzheimer’s patients can have a difficult time judging temperature. Often the person may forget the dangers of stoves, curling irons, or space heaters. Additionally, the person may have sensitivities to heat or cold and might not react to heat or cold quickly enough to prevent an accident. To help avoid scalding, consider setting your home water heater at 40 degrees, and help the person mix hot and cold water for bathing.
