Colder Weather Ahead: How to Stay Safe This Winter

(December 18, 2025) – As colder temperatures arrive across the region, Lakelands Public Health is reminding residents that very cold temperatures or wind chill can be dangerous and that taking precautions can help prevent serious health problems. Cold-related illnesses can happen quickly, especially for people who are more vulnerable to the cold. 

Lakelands Public Health monitors weather conditions across all communities we serve. Aligned with Environment and Climate Change Canada, a cold warning is issued when temperatures or wind chill are expected to reach –30°C or colder for two hours or more. When these conditions are forecasted, a warning is publicly shared through the Lakelands Public Health website, social media channels (Facebook and Instagram) and with community partners.  

“As we move through the winter season, it’s important to stay informed and take steps to protect ourselves and those around us,” said Julie Bromley, Manager of Strategic and Emergency Services with Lakelands Public Health. “Checking in on people who may be at higher risk and knowing where to find local supports can make a real difference during extreme cold.” 

However, people can be affected by cold well before a warning is issued, especially if they are outdoors for long periods or do not have adequate clothing or shelter. Anyone at higher risk should take precautions whenever temperatures drop, even if no official warning has been issued. Lakelands Public Health may issue a cold warning and communicate directly with community partners who support individuals at risk before a public cold alert is issued.   
 
Who is Most at Risk Extreme cold can affect anyone, but some people are at greater risk of serious health impacts, including: 

• People experiencing homelessness or living in homes without reliable heat 
• Older adults, infants and young children 
• People with medical conditions including diabetes, respiratory and cardiovascular conditions 
• People who take medications or substances that affect body temperature 
• People who work or spend long periods of time outdoors 
• People who rely on mobility devices 
• Newcomers who may be unfamiliar with Canadian winter conditions 

Common Cold-Related Health Impacts Cold-related illnesses can develop quickly and may become life-threatening. 

• Hypothermia Early signs include shivering, numb hands, tiredness, and shallow breathing. As hypothermia worsens, symptoms may include confusion, slow movements, pale or blue skin, and loss of consciousness. 
• Frostbite and Frostnip Frostnip causes skin to become pale or yellowish and cold to the touch but still soft. Frostbite is more serious and can cause hard, numb skin, blisters, and permanent damage. It most often affects the nose, ears, hands, and feet. 
• Increased risk or worsening of cardiovascular and respiratory conditions Cold weather can cause the heart to work harder and breathing to become faster as the body tries to stay warm. This can increase the risk of heart attacks and strokes and worsen existing heart or lung conditions, particularly for vulnerable individuals. 

Anyone showing signs of severe frostbite, hypothermia, or worsening heart or lung conditions needs immediate medical attention. 

How to Stay Safe Cold-related illnesses are often preventable. Residents can help protect themselves and others by: 

• Checking on neighbours, friends, and family who may need extra support 
• Dressing in warm layers and wearing a wind-resistant outer layer 
• Wearing warm socks, gloves or mittens, a hat, and a scarf 
• Spending time in heated indoor spaces when temperatures drop 
• Changing into dry clothing as soon as possible if you get wet 
• Talking to a health care provider if you have health conditions that increase your risk 
• Making sure your home heating system is working properly 
• Preparing a home emergency kit and a winter car kit in case of power outages or storms 
• Sign up for weather alerts for your area using the Government of Canada’s WeatherCan app.
