Coping with hot weather

Summertime can be very enjoyable with sunny, warm long days however excessive heat can lead to conditions such as heat stress and heat stroke of which people over the age of 65 years are more susceptible

As we age our body’s mechanisms to cope with heat alters. Skin becomes thinner with age and we gradually lose the ability to perspire and regulate our body temperature. Older people therefore tend to overdress as they don’t feel heat the same way.

Factors that may increase the risk of dehydration, heat stress and heat stroke in elderly people include:

  • Living alone – When living alone there is no one to assist if the person ignores the signs of dehydration
  • Self care problems – Reduced mobility may make it difficult for elderly person to adequately care for them selves in hot weather e.g. access water, prepare the house etc.
  • Chronic medical conditions – Heart, lung and kidney disease may increase risk of dehydration and heat stress.
  • Medications –Some medications can interfere with the ability to manage hot weather e.g. antipsychotic drugs commonly given to Alzheimer’s patient, anticholinergic drugs, sedative, beta blockers, diuretics, antihistamines and some antidepressants
  • Caffeine and alcohol intake

Below are the signs and symptoms that you and your loved ones should be aware of regarding heat related conditions

Symptoms of heat exhaustion: Warning body is getting too hoot

  • Thirst, giddiness, weakness, lack of coordination
  • Nausea
  • Profuse sweating
  • Pulse normal or slightly raised

  • Dry swollen tongue
  • Shallow, rapid breathing

Tips for coping with the heat

There are some simple measures that you and your loved ones can take to reduce your risk of heat related illness

  • Stay cool – draw blinds/curtains, turn on air conditioning, use wet towels or cool shower and sit in front of electric fan
  • Stay indoors and avoid strenuous activity including exercise, gardening and house work
  • Wear lightweight clothing
  • Drink cool water regularly throughout the day (not just when you feel thirsty)
  • Eat little often rather than large meals. Try to eat cold meals which contain water e.g. salad and fruit
