Heat Warning for Elgin St. Thomas – August 3, 2016

(Effective August 4 – August 5, 2016)

St. Thomas, Ontario,

The Health Unit is sending out a Heat Warning because Environment and Climate Change Canada is predicting hot humid weather for the rest of the week. When it is really hot and humid outside, your body may not be able to cool properly. This can lead to heat exhaustion or even heat stroke which can be deadly.

The Health Unit sends out a heat warning when the weather forecast calls for the following conditions two days or more in a row:
 a daytime high temperature that is above 31 without the nighttime temperature cooling down below 20 or
 a humidex reading greater than 40 degrees Celsius.

Symptoms of heat-related illness may include: rapid breathing, dizziness or fainting, vomiting, rapid heartbeat, and extreme thirst. Your body may make less urine (pee) and your urine may be darker in colour.

If you or anyone you take care of has these symptoms, please move to a shaded or air conditioned area, drink plenty of fluids, and rest. Contact your health care practitioner, a friend and/or a family member.

Heat strokes are considered a medical emergency. Call 911 or your local emergency number immediately if you or someone you care for has a high body temperature, is unconscious, confused
or has stopped sweating.

Friends, family and neighbors should check on those who may need help keeping cool or taking other preventative actions. For more information on heat-related illness, visit www.elginhealth.on.ca/extremeheat


“The elderly, very young and people with chronic illnesses are at higher risk of suffering from heat related illness,” said Dr. Joyce Lock, Medical Officer of Health. “However, even healthy people can be affected if they participate in strenuous activities and do not take precautions.”
