This stretch of hot weather increases the risk of heat-related illnesses, especially for older adults, young children, people with chronic illnesses, and those without access to air conditioning. Health officials stress that extreme heat can impact anyone, and taking preventive steps is key to staying safe.
Health risks and warning signs
Prolonged exposure to high temperatures can lead to heat exhaustion or, in more serious cases, heat stroke. Symptoms of heat exhaustion include headache, dizziness, nausea, thirst, dark urine, and fatigue. If not addressed quickly, these symptoms can progress into heat stroke—a life-threatening condition that requires immediate medical attention.
Early signs of heat stroke may include confusion, red or hot skin, dizziness, nausea, and loss of consciousness. Health authorities urge anyone experiencing these symptoms, or observing them in others, to seek emergency care immediately and begin cooling the affected person by moving them to a shaded or air-conditioned area and applying cold water or ice packs.
Staying cool and safe
To reduce the risk of heat illness, residents are encouraged to drink water frequently, even before feeling thirsty. Staying in a cool environment is also important. Keeping blinds or shades closed during the day, opening windows if it’s cooler outside, and using fans or air conditioning can help regulate indoor temperatures.
If your home remains hot, consider spending time in public cooling centres such as libraries, community centres, malls, or shaded parks. Outdoor activities should be scheduled during the cooler parts of the day, typically in the early morning or late evening.
Wearing light-coloured, loose-fitting clothing and wide-brimmed hats can also help limit heat exposure. It is essential never to leave children, adults, or pets in a parked vehicle, even for a short time.
Community support and heat safety
Public health officials recommend checking in on vulnerable individuals—including seniors and those living alone—several times a day during a heat wave. Even a short phone call or visit can make a difference.
Keeping your home cool by blocking direct sunlight and minimizing indoor heat sources is another way to stay safe. Taking a cool shower or bath, resting in air-conditioned areas, and staying out of direct sunlight can help lower body temperature.
Heat-related symptoms such as swelling, rashes, cramps, fainting, or worsening of existing health conditions should be taken seriously. Knowing the signs and acting quickly can prevent more serious health outcomes.
