Sunburn: First Aid Care, Symptoms, and When to Seek Medical Help in Canada
A sunburn occurs when skin is exposed to ultraviolet (UV) rays for extended periods. It is classified as a first-degree burn, meaning it affects only the outer layer of the skin. While many sunburns are mild and heal on their own, more severe cases can cause significant discomfort and may require medical attention.
Across Canada, sunburn is a common warm-weather injury—especially during summer months, outdoor work, travel, and recreational activities. Even in cooler regions, UV exposure can be significant, particularly at higher elevations or near reflective surfaces like water and snow.
Understanding how to recognize and manage sunburn is part of general first aid awareness for Canadians of all ages.
How to Care for a Sunburn
Most mild sunburns can be managed at home using basic first aid principles.
Cool the Affected Area
- Take a cool (not cold) bath or shower
- Apply a cool, damp cloth to the sunburned area for 10–15 minutes
- Repeat several times throughout the day as needed
Cooling the skin helps reduce inflammation and discomfort during the early stages of sunburn.
Moisturize and Protect the Skin
- Apply a fragrance-free moisturizer, aloe vera gel, or over-the-counter hydrocortisone cream
- As the skin begins to peel, continue moisturizing to reduce itching and dryness
- Avoid products containing alcohol, which can further irritate the skin
Skin peeling is part of the body’s natural healing process and should not be forced or picked.
Blister Care
- Do not pop blisters
- Intact blisters protect the underlying skin from infection
- If blisters rub against clothing, cover them loosely with a non-stick dressing
Blister management is often discussed when learning about minor burns during standard first aid training in Canada.
Pain Relief and Hydration
- Over-the-counter pain relief may help manage discomfort
- Drink fluids regularly to prevent dehydration, especially during hot or dry conditions common in Canadian summers
When to Seek Medical Attention
Medical care should be sought if any of the following occur:
- The sunburn is severe or covers a large area
- Fever, chills, nausea, rash, or intense pain develop
- Dizziness, fainting, rapid breathing, or pale, clammy skin occur
- Signs of dehydration appear, such as excessive thirst or reduced urination
- The burn does not begin to heal within a few days
These symptoms may indicate complications that require professional medical assessment.
Why Sunburn Awareness Matters for Canadians
Sunburn may seem minor, but severe cases can lead to infection, dehydration, or heat-related illness. For Canadians working outdoors, attending summer events, or spending time at cottages, beaches, and parks, understanding burn care and prevention is especially important.
Recognizing the difference between a mild sunburn and a more serious burn is part of first aid and safety training, which helps Canadians respond appropriately until medical care is available.
