Hypothermia
Protect yourself and your loved ones this winter from hypothermia.
What is hypothermia?
Hypothermia (“hypo” meaning low, “thermia” meaning temperature) is caused when the body is exposed to the cold for a long time and loses more heat than it can generate.
Who is at risk?
Anyone can get hypothermia. Certain people are at a greater risk and need to be extra careful:
- older people
- people with disabilities who live alone
- babies and children
- people with a tall, slim build
- people with circulation problems
- people outside for long periods at a time
- people with inadequate shelter, clothing, and food
- people who drink alcohol or smoke
- people who are on certain medications
- people who use drugs
Signs and symptoms of hypothermia:
- confusion (poor judgement or slowed thinking)
- problems speaking
- stiff movements
- lack of energy (lethargy)
- drowsiness, possible loss of consciousness
People with hypothermia will begin shivering, but this sign can decrease and disappear in later stages.
Preventing hypothermia:
- dress in layers
- cover exposed skin
- stay warm and stay dry
- drink warm fluids, no alcohol, or caffeine
- keep active, but avoid sweating
- limit the amount of time in the cold
- take warm-up breaks
- stay indoors during cold weather warnings (Government of Canada)
- watch for signs of hypothermia
- help and check on others
Treating hypothermia

- seek shelter from the weather
- lay flat (or keep the person lying flat)
- change to dry clothing
- warm the body any way possible
- drink warm water, milk, or juice
