Preventing Heat-related Illness

Access cooling centre locations

Due to COVID-19, cooling centers are limited. If you or someone you know require assistance due to the heat, please call Lambton Public Health at 519-383-8331 or contact us online.

Other important steps

  • Drink plenty of fluids, especially water.
  • Avoid strenuous activities between 11 a.m. and 3 p.m. when the sun’s rays are strongest. Reschedule outdoor activities to a cooler time of day.
  • Avoid going out in the sun, if possible. If you are outdoors, seek shade and wear sunscreen. Wear light-weight, loose fitting clothing and sunglasses.
  • If you are taking medication or have a health condition, ask your health care provider if it increases your health risk in the heat and follow their recommendations.
  • Check on elderly family members, neighbours, persons with disabilities, and persons with chronic illnesses daily to make sure they are keeping cool and hydrated.
  • Take cool showers or baths, or use cool, wet towels on your face, neck or arms.
  • The use of a fan alone may not provide enough relief from the heat. Avoid heavy meals and using your oven. Keep curtains closed to block the sun during the day.
  • Never leave anyone or pets in a parked car. Pets need a cool location and fresh water.

Know the signs for heat-related illness

Symptoms of heat-related illness may include: rapid breathing, dizziness or fainting, vomiting, rapid heartbeat, extreme thirst and decreased urination with unusually dark yellow urine. For anyone experiencing these symptoms, Lambton Public Health suggests the following actions be taken in order to cool off as soon as possible: move to a shaded or air conditioned area, drink plenty of fluids, and rest. Contact your health care provider, a family member or friend.

Heat strokes are considered a medical emergency. Call 911 immediately if you are caring for someone who has a high body temperature, is unconscious, confused or has stopped sweating. Friends, family and neighbours should check on those who may be vulnerable and who may need help keeping cool or taking other preventive actions.
