Hotter days can impair the body’s ability to regulate temperature, which is especially challenging for older adults who adjust poorly to sudden changes and often have chronic conditions or medications that affect temperature control. Heat exhaustion indicates the body can’t stay cool, causing thirst, dizziness, weakness, and nausea, with possible excessive sweating and clammy skin. Resting in a cool place and hydrating can help, but if symptoms persist, seek medical care to prevent heat stroke. Heat stroke, marked by a temperature over 104°F, confusion, dry skin, and a rapid pulse, is a medical emergency requiring immediate cooling and medical attention. Enjoy the summer, but be safe!
