Seniors' Guide to Staying Safe in Hot Weather

Why is it important for older people to protect themselves from the heat?

Older people are a particularly vulnerable group when it comes to heat-related problems because they have more difficulty adapting to sudden changes in temperature compared to younger people. This vulnerability is exacerbated by chronic diseases or medications used to treat these conditions, which can affect the body's ability to handle heat.

What can happen if older people are exposed to heat in an unhealthy way?

If an older person does not have access to the resources necessary to protect themselves from the heat, they are at greater risk of experiencing hyperthermia, a condition in which the body's heat regulatory systems fail. Examples of hyperthermia include heat stress, heat fatigue, heat cramps, heat stroke, and sudden dizziness.

Hyperthermia is caused by a combination of health problems, lifestyle factors, and high temperatures. For example, if an older person is not well hydrated, does not have access to air conditioning, is dressed too warm for the climate, does not have access to transportation, and is in a crowded place, they are more likely to suffer from hyperthermia.

Health problems that can increase the risk of hyperthermia include alcohol abuse, medications that reduce sweating, high blood pressure, use of multiple medications, poor blood circulation, diseases that cause weakness (particularly affecting the heart, lungs, and kidneys), and being significantly over or underweight than recommended.

How can older people protect themselves from the heat?

Although some causes of hyperthermia are difficult to avoid due to chronic illnesses, there are still several steps seniors can take to protect themselves from the heat:

• Make sure you have access to cool places, whether at home or in public places, with air conditioning.
• Avoid going out during high temperature warnings.
• Drink fluids continuously throughout the day (do not wait until you are thirsty).
• Cool down by taking cold showers or baths.
• Rest and avoid excessive movements.
• Avoid using the stove or oven.
• Wear loose, light-colored, lightweight clothing.
• Have someone around who can take care of you.

It is important to be informed about how to protect yourself from the heat. Consult your doctor for more information about how your specific medical problems may be affected by high temperatures.
