People of all ages can be affected by the heat and should take precautions. Seniors over the age of 65 years are more prone to heat-related illness than younger people for several reasons:
- The older body takes longer to adjust to sudden temperature changes.
- Chronic disease may alter the normal body response to heat.
- Medications can impair the body's ability to regulate its temperature or inhibit perspiration.
- The elderly sometimes don't feel thirsty. They drink less to avoid having to go to the bathroom frequently.
