Hot weather safety for older adults
Excessive heat can be dangerous for everyone, but it poses a greater risk to older adults, especially those with existing health conditions. The body’s ability to regulate temperature diminishes with age, and many older people take medications or have conditions that interfere with sweating and cooling. Sudden exposure to high temperatures can therefore be harmful.
Types of heat-related illness
Heat syncope causes sudden dizziness due to overheating, particularly in those on heart medications. Resting in a cool place and drinking water can help.
Heat cramps are painful muscle spasms triggered by physical activity. Relief involves stopping activity, hydrating with water or electrolyte drinks, and avoiding caffeine or alcohol.
Heat edema results in swelling of feet or ankles. Elevating the legs may reduce this.
Heat rash is caused by excessive sweating and appears as red, itchy bumps. Keeping skin dry and staying cool can relieve symptoms.
Heat exhaustion signals the body is struggling to cool down. Symptoms include dizziness, thirst, and nausea. Moving to a cool place and hydrating is essential. Left untreated, it can progress to heat stroke.
Heat stroke is a medical emergency, marked by confusion, high body temperature, and hot, dry skin. Immediate medical attention is required.
Sunburn can also result from prolonged exposure. Prevent with protective clothing and sunscreen. Treat with cool baths and moisturisers.
Risk Factors
Increased vulnerability to heat is associated with chronic illnesses (like heart or kidney disease), dehydration, ageing skin, use of multiple medications, alcohol consumption, and lack of access to cool environments.
Safety Tips
Stay hydrated with non-alcoholic, non-caffeinated drinks. Dress in light, breathable fabrics. Avoid strenuous outdoor activities during peak heat. Seek cool indoor locations when temperatures rise. Use sunscreen and protective clothing outdoors. Ask your doctor if any medications increase heat sensitivity.
