With the arrival of hot and humid weather, Environment and Climate Change Canada will issue a Heat Warning for our region (South) when the following circumstances occur:
An Extended Heat Warning will be issued when the Heat Warning (see above) lasts longer than two days and continues for three or more days.
Lambton Public Health will issue a news release to notify the Lambton County community.
As the humidex value increases, it becomes harder for the human body to regulate its temperature.
Extreme heat can affect your health many ways: heat stroke, heat exhaustion, dehydration, fatigue, cramps.
Heat exhaustion is a milder form of heat related illness that may develop after several days of exposure to high temperatures and inadequate replacement of fluids.
Heat strokee is the most serious heat-related illness. It occurs when the body is unable to control its temperature. When the body loses its ability to cool itself, the core body temperature rises rapidly. Heat stroke can cause permanent damage to vital organs and may lead to death if emergency treatment is not provided.
