What are the warning signs of heat stroke in older adults?

✓ Accepted answer

Heat stroke in older adults is a life-threatening medical emergency characterized by a core body temperature of 104 degrees Fahrenheit or higher, confusion, and altered mental status.

• Confusion or Irritability: Unlike mild dehydration, heat stroke causes the brain to malfunction. Look for sudden disorientation, slurred speech, or extreme agitation that differs from her baseline personality.
• Hot, Dry, or Damp Skin: While some victims sweat profusely, others may stop sweating entirely. Touch her skin; if it is hot, dry, and flushed red, seek immediate emergency care. Note that the elderly often have impaired thermoregulation, so these signs can appear abruptly.
• Rapid Pulse and Heavy Breathing: Her heart rate may become very fast and weak, while breathing turns rapid and shallow as the body tries to cool itself in a failed attempt to maintain homeostasis.
• Fainting or Loss of Consciousness: This is a critical red flag. If she becomes confused or loses consciousness, call 911 immediately. Do not wait to see if she recovers on her own.
• Headache and Nausea: Severe headaches, dizziness, and vomiting often accompany the onset of hyperthermia. These symptoms are more intense than typical heat exhaustion.

Because older adults may have diminished thirst sensation and slower physical responses, they often deny feeling hot even when their internal temperature is rising dangerously. If you observe any combination of confusion and high body temperature, treat it as heat stroke. Call emergency services, move her to a cool environment, and use ice packs or cool showers to lower her temperature while waiting for help.
