May 30, 2017 -Peterborough Public Health Activates Heat Warning System
With summer quickly approaching and warmer temperatures imminent, Peterborough Public Health has activated its Heat Warning and Information System (HWIS) to advise residents of the best way to protect their health when temperatures soar.
Environment and Climate Change Canada will issue Heat Warnings 18 to 24 hours in advance of the heat event. Forecasters will assess if two or more consecutive days of weather that meet either the humidex or temperature criteria (daytime highs or nighttime lows) are expected in the region. If so, a Heat Warning will be issued. Information about these warning levels is available on the Extreme Weather – Heat webpage on www.peterboroughpublichealth.ca and outlined below.
The Ontario Heat Warning Protocol includes two warning levels:
Level 1: Heat Warning
A Heat Warning is issued when two consecutive days are forecasted to have a daytime high temperature greater than or equal to 31C AND a nighttime temperature greater than or equal to 20C or a humidex greater than 40. This level of reminds residents of the following core messages: to keep their home cool, stay out of the heat, keep the body cool and hydrated, assist others, and recognize the symptoms of heat exhaustion.
Level 2: Extended Heat Warning
An Extended Heat Warning will be issued for a heat event lasting three or more days. This level of warning reminds residents of the core messages above, in addition to providing details on how and where to stay cool, advising suspension of strenuous outdoor activitie
s, reminders to assist vulnerable groups, and to watch for further information through the media and the Public Health website.
Extreme heat events are a potentially significant health risk and can have a severe impact on the health of vulnerable populations including infants, the elderly, shut-ins, persons with chronic diseases, the morbidly obese and the marginally housed. Heat related illnesses such as dehydration, heat cramps, heat exhaustion, and heat stroke are preventable. Most healthy people can tolerate a short period of hot and humid weather as long as they stay cool and drink plenty of fluids. It is important to be aware that some medications may increase the health risks from extreme heat events.
Peterborough Public Health encourages all stakeholders to advise vulnerable clients of the heat advisory system and precautions they can take to prevent and manage heat related illness.
How to Protect Yourself During Hot Weather:
- Drink lots of water and natural fruit juices even if you don’t feel very thirsty. Avoid alcoholic beverages, coffee and cola.
- Avoid going out in the direct sun or heat when possible. If you must go outside, stay in the shade as much as possible and plan to go out early in the morning or evening when it is cooler.
- Go to air conditioned or cool places such as shopping malls, libraries, community centres or a friend’s place.
