In addition to the water refill stations, the tap water in public washrooms at municipal parks, including King Edward Park and Millennium Park, is from the City’s water supply.

People suffer heat-related illnesses when their body temperature quickly rises and they are unable to cool themselves. The risk of heat-related illness increases with the amount of time spent in the heat, the temperature and an individual’s sensitivity to heat. If you feel faint, find it hard to breathe, or feel confused and disoriented because of the heat, call 911 or go to the Emergency Department.

How to Protect Yourself During Hot Weather:

  • Drink lots of water 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 go outside, rest frequently in green spaces with lots of shade and plan to go out early in the morning or in the evening when it is cooler.
  • Use an air conditioner if possible, and if you don’t have air conditioning, keep shades or drapes drawn and blinds closed on the sunny side of your home, but keep windows slightly open.
  • Wear loose fitting, light clothing and a wide brimmed hat.
  • Keep lights off or turned down low.
  • Take a cool bath or shower periodically or cool down with cold, wet towels.
  • Avoid heavy meals and using your oven.
  • Avoid intense or moderately intense physical activity.
  • If you are taking medication or have a health condition, ask your doctor or pharmacist if it increases your health risk in the heat and follow their recommendations.

Heat illnesses include heat stroke, heat exhaustion, heat fainting, heat edema (swelling of hands, feet, and ankles), heat rash, and heat cramps. Watch for symptoms of heat illness, which may include:

  • heavy sweating;
  • muscle cramps and/or headache;
  • weakness, dizziness, or fainting;
  • nausea or vomiting;
  • paleness, tiredness;
  • rapid breathing and heartbeat;
  • extreme thirst; or
  • decreased urination with unusually dark yellow urine.

Extreme heat is often accompanied by poor air quality.  Peterborough Public Health encourages you to monitor the Air Quality Health Index found as a link on the Ministry of the Environment, Conservation & Park’s website and plan outdoor activities accordingly.
