Tips to safely enjoy hot summer weather and avoid heat-related health problems

Heading out to enjoy the sun? A few simple tips can help you and your family to stay safe during a heat wave. “People can have fun in the sun but they should also be aware of the risks of heat exposure,” said Dr. Charl Badenhorst, Northern Health Medical Health Officer. “Heat illness occurs when the humidex is at or near 40 or if there are extended periods of high temperatures.

“The humidex tells us how hot the weather feels to the average person. It combines the temperature and humidity into one number, taking into account the two most important factors that affect summer comfort.”

The symptoms of heat illness include rapid breathing, headache, weakness or fatigue, nausea and muscle cramps. People with these symptoms should move to a cool environment. They should rest and drink cool, non-alcoholic beverages. If an individual’s symptoms worsen or are severe, they should visit an emergency room or their family doctor.

To protect you and your family from heat illness, keep the following in mind:  

• Watch or listen for humidex reports issued by Environment Canada
• Drink lots of water and natural juices, even if you don't feel thirsty
• Avoid strenuous activity during mid-day when the temperature is at its peak.
• Avoid going out in the blazing sun. If you must go out, stay in the shade or wear a hat.
• Apply a sunscreen with a Sun Protection Factor (SPF) of 15 or more if you’re outside shopping or doing errands. Upgrade to SPF 30 if you’ll be out the whole day in direct sun.
• Apply sunscreen 15 to 30 minutes before sun exposure, and look for waterproof sunscreen if you sweat heavily or plan to swim.
• Use a fan to bring in cooler air from outside. Be sure to use a fan in a room with windows or doors open to the outside.
• Check on relatives, friends and neighbors who live alone, have difficulty caring for themselves, or are immobile to ensure they aren't suffering from the heat.
• Never leave infants, small children or pets in a parked car.
• Avoid drinking alcohol or caffeinated drinks, as these can cause dehydration.
• If you are taking any medications, check with your doctor or pharmacist to see if your medication puts you at a higher risk for developing heat related illness
