After a long Canadian winter, most of us look forward to warmer temperatures and sunny summer days. While summer brings opportunities to enjoy the outdoors, it is also important to recognize the health risks that can come with extreme heat.
Hot weather can affect anyone, but older adults, young children, individuals with chronic health conditions and those who work or exercise outdoors are particularly vulnerable to heat-related illnesses.
One of the most important things you can do during hot weather is stay hydrated. Don’t wait until you feel thirsty to drink water. By the time thirst sets in, your body may already be showing signs of dehydration. Carry a water bottle when you’re out and make a habit of drinking fluids throughout the day.
It is also important to limit strenuous activities during the hottest parts of the day, typically between 11 a.m. and 4 p.m. If you plan to garden, exercise or work outdoors, consider doing so during the early morning or evening hours when temperatures are cooler.
Knowing the warning signs of heat-related illness can help prevent a medical emergency. Early symptoms may include excessive sweating, dizziness, headache, muscle cramps, fatigue and nausea. If left untreated, heat exhaustion can progress to heat stroke, a serious condition that requires immediate medical attention.
Signs of heat stroke may include confusion, loss of consciousness, a rapid pulse, hot dry skin and a body temperature that continues to rise. If you suspect someone is experiencing heat stroke, call 911 immediately and move them to a cooler location while waiting for help.
Seniors should take extra precautions during heat waves. Certain medications and medical conditions can affect the body’s ability to regulate temperature. Family members and neighbours are encouraged to check in on older adults during periods of extreme heat to ensure they are safe, comfortable and staying hydrated.
The good news is that most heat-related illnesses are preventable. Staying hydrated, wearing lightweight clothing, seeking shade, using air-conditioned spaces when possible and checking on vulnerable family members can go a long way toward keeping everyone safe.
Summer is a wonderful time to enjoy parks, patios, festivals and outdoor activities. By taking a few simple precautions, you can stay healthy and make the most of the season.
Have a safe and enjoyable summer.
