Heat Illness

For most people, heat-related illnesses happen when temperatures are high for a number of days (particularly if the night time temperatures do not drop), or if the humidity is high. While the health risks related to heat are higher for certain groups (such as seniors, 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, signs and symptoms. This information can help you to plan ahead, and take action to protect yourself and your family.
