Heat events or “heat waves” occur when weather conditions combine to create higher than normal temperature and/or humidity levels over a period of several days.

Heat affects the body’s ability to regulate its temperature and it can become overworked if exposed to heat for too long. This can lead to dehydration, heat exhaustion, other serious illnesses or even death. While the health risks related to heat are higher for certain groups, such as older adults, young children, people taking certain medications and people with chronic conditions, everyone is potentially at risk.

Fortunately, most heat-related illnesses can be prevented or treated if you are aware of the risks and symptoms. The following information can help you to plan ahead, and take action to protect yourself and your family.
