Summer often brings very high temperatures that may last for days or
weeks. A heat wave can cause severe heat-related illness, such as heat
exhaustion and heat stroke. Very high body temperatures may damage the
brain, other vital organs or cause death.
The body usually cools itself by sweating. But during hot and humid
weather, sweating may not be enough and body temperature can rise
rapidly. Sweat will not evaporate as quickly and prevents the body from
cooling itself. Other conditions that affect body cooling include old
age, obesity, fever, dehydration, heart disease, poor circulation,
sunburn, and drug and alcohol use. Those at most risk are:
- Infants;
- People 65 years of age or older;
- Overweight people;
- Those who overexert during work or exercise;
- People who are ill or on certain medications.
When temperatures are extremely high, stay cool and use common sense:
- Drink plenty of fluids, especially during heavy exertion. Avoid
drinks with alcohol, which increase fluid loss.
- Replace salt and minerals lost through heavy sweating. Drink fruit
juices or a sports beverage. Do not take salt tablets or change a
low-salt diet without advice from your doctor.
- Wear lightweight, light-colored and loose-fitting clothing. A
wide-brimmed hat will provide shade in the sun.
- Wear a sunscreen of SPF 15 or higher to reduce the risk of
sunburn.
- Stay indoors in an air-conditioned area such as your home, the
shopping mall, public library or movie theatre. Electric fans do not
cool well during a heat wave.
- Limit physical activities. Rest often. Plan outdoor activities
before noon or in the evening.
