Who says winter, says cold!
By May A.
The winter season brings a lot of benefits such as outdoor activities, snow, the festive atmosphere of the holiday season, but also a few problems such as cold, ice, slippery roads, etc. It is important to protect your body by covering yourself from head to toe with good winter clothes, because unfortunately, prolonged exposure to cold with inadequate protection can cause frostbite.
What is frostbite?
It is an injury to the skin due to freezing, caused by cold weather, especially during the presence of moisture and gusts. The most sensitive parts of the body are the cheeks, the nose, the ears, the chin, the fingers and the toes.
What are the symptoms to watch for?
There are 2 types of frostbite:
➢ Superficial frostbite:
• The skin turns red and then white with sometimes a grayish look
• A tingling, numbness, pain or burning sensation
• Some small superficial blisters
• Difficulty moving the affected area
➢ Deep frostbite:
• Insensitivity to the affected area
• The skin becomes cold, white, shiny
• Presence of large blisters
What are the possible complications following frostbite?
➢ Greater sensitivity to cold
➢ Risk of developing frostbite again
➢ Long-term numbness in the affected area
➢ Gangrene potentially leading to amputation
➢ Possible hypothermia
Who is at risk?
Some people are more at risk of experiencing the harms of the cold, such as:
o Children of all ages
o The elderly
o People with reduced mobility
o People with loss of autonomy
o People with problems related to drug and alcohol use
o Homeless people
o People working outside for long hours
o People suffering from certain chronic diseases, such as:
• heart or respiratory failure
• certain neurological disorders
• people suffering from Raynaud's phenomenon or acrocyanosis
How to take care of frostbite?
Usually, frostbite is benign but in any case, do not hesitate to contact a health care professional for any questions.
Here is what you should do if you have frostbite:
• Quickly take refuge in a warm place
• Avoid re-exposing cold-weathered skin for several hours
• Slowly warm up the affected area (eg. hands) by placing them under the armpits, between the thighs or simply by blowing on them
• Gently remove the clothes covering the frostbite
• Place the affected area in warm water (hot water exponentially increases the burning sensation)
• Move the affected joints to activate the blood circulation except in case of frostbite in the feet, the person must avoid moving
• Take pain relief medications such as acetaminophen or ibuprofen if needed, please check with your pharmacist at all times if this type of treatment is right for you
• Cover the blisters with a dry dressing and consult a healthcare professional to assess the severity of the condition
• Drink plenty of fluids, especially water in order to hydrate
• Avoid smoking or drinking alcohol, which can lower your body temperature
You should avoid doing this at all times:
- Rubing and massaging the affected area
- Applying creams or ointments or other products to the damaged skin
- Covering the affected area with snow, cold or hot water
- Use a heating object or a heat source
How to prevent frostbite?
• Check the outside temperature and the wind factor before planning an outdoor activity
• Dress warmly and cover any exposed part of the body with a tuque, mittens, scarf and warm boots
• Bring snacks and, hot and sugary drinks
• Take refuge inside occasionally if possible
• Wear multiple layers of clothing that are both, waterproof and windproof
• Do not smoke or drink alcohol
• Always be on the move to activate blood circulation and keep warm without causing body exhaustion
• Have an emergency kit with a blanket, spare clothing, etc.
• Watch for signs of frostbite
Enjoy the joys of winter, but do not forget to cover yourself!
