Sunburns are a common occurrence, especially during the summer months. They are caused by overexposure to the sun's ultraviolet (UV) rays or artificial UV light sources. While sunburns typically affect the skin, causing redness, pain, and peeling, there may be concerns about whether they can also impact the muscles. In severe cases, sun exposure can lead to heat illnesses, including heat cramps, heat exhaustion, and heat stroke. So, can sunburn cause muscle damage? Let's explore this topic further and understand the potential risks and impacts of sun exposure on both the skin and the body's muscles.

What You'll Learn
Sunburn severity: first, second, and third-degree burns
Sunburns are caused by exposure to the sun's UV rays or artificial UV light sources. Sunburn severity is classified into three types: first, second, and third-degree burns, based on the depth and size of the affected area.
First-degree sunburns damage the skin's outer layer, causing redness, discomfort, and peeling during the healing process. These burns usually heal by themselves within a few days and do not require specialist treatment.
Second-degree sunburns penetrate the skin's outer layer and damage the underlying layer. Symptoms include redness, pain, blistering, and peeling. This degree of sunburn may take several weeks to heal and might require specialist burn cream, burn dressings, or other treatments. In some severe cases, hospital treatment may be necessary, especially if heatstroke is also present.
Third-degree sunburns are rare but require immediate emergency treatment. They cause severe damage to the skin, and symptoms can include blistering, facial swelling, headaches, dizziness, and nausea.
It is important to note that sun poisoning is different from sunburn and occurs when an individual is exposed to the sun's UV rays without protection for an extended period. People with fair skin and hair are at a higher risk of sun poisoning, and it can present symptoms such as fever, chills, and nausea, in addition to the typical sunburn symptoms.

Sun poisoning symptoms and treatment
Sun poisoning, also known as a severe sunburn, is caused by prolonged exposure to the sun without adequate protection. It can also occur with mild sun exposure if one has certain risk factors, such as a skin condition or medication that increases sensitivity to the sun. While sun poisoning is not a formal medical term, it is characterised by symptoms that are more severe than typical sunburns.
Symptoms of sun poisoning include:
- Red rash
- Blisters
- Severe pain
- Swelling
- Fever
- Chills
- Nausea
- Headache
- Dehydration
- Lightheadedness
- Confusion
If you experience any of these symptoms, it is important to seek medical attention as soon as possible. Doctors may prescribe treatments based on specific symptoms, such as pain and fever medications, antibacterial wound creams, or oral antibiotics for skin infections.
To treat sun poisoning at home, you can:
- Soak or shower in cool water to ease discomfort
- Apply aloe vera or anti-itch treatments to the affected area
- Drink plenty of water and electrolytes to stay hydrated
- Wear lightweight, long-sleeved shirts and long pants to protect your skin from further sun exposure
To prevent sun poisoning, it is crucial to follow sun protection measures, including wearing sunscreen with an SPF of at least 30, seeking shade, and covering up with clothing, especially during the sun's peak hours between 10 a.m. and 2 p.m.

Skin damage and ageing
Sunburn is a visible reaction of the skin's exposure to ultraviolet (UV) radiation, which is part of sunlight, or UV light sources such as tanning beds. The sun's UV rays can also penetrate clouds, meaning sunburn is possible even on cloudy days.
Sunburn causes skin damage and ageing. Even mild burns will turn the skin painfully red, and the skin may feel hot to the touch. The pain and skin colour changes tend to start a few hours after exposure and peak after 24 hours. Sunburn usually heals itself in a few days to a week, but deeper burns may take several weeks.
The skin damage caused by sunburn is permanent. Frequent sunburns increase your risk of sun damage and premature skin ageing, including discoloured age spots, freckles, red veins, wrinkles, and sagging. This is due to the UV rays causing invisible damage to the skin.
To prevent skin damage and ageing caused by sun exposure, it is important to take precautions when spending time in the sun. This includes wearing sunscreen, protective clothing, and staying out of direct sunlight, especially during the hours of 10 am and 2 pm when the sun is strongest.

Preventing sunburn
Sunburn is caused by overexposure to UV rays from the sun or artificial sources such as a sunlamp or tanning bed. Sunburn can cause skin redness, peeling, pain, swelling, blisters, and an increased risk of skin cancer. To prevent sunburn, follow these steps:
- Plan your day to avoid excessive sun exposure, especially during peak hours when the sun's UV rays are strongest, typically between 10 am and 2 pm. Remember that you can still get sunburnt on cool or overcast days.
- Check the UV index: When the UV index is 3 or higher, use sun protection. You can check the UV levels through official sources, such as weather agencies or mobile apps.
- Cover your skin: Wear sun-protective clothing that covers as much skin as possible. Choose loose-fitting garments that will keep you cool while protecting your skin.
- Wear a hat and sunglasses to protect your face and neck from direct sunlight.
- Apply sunscreen: Use a broad-spectrum sunscreen with a high SPF rating to block both UVA and UVB rays. Apply sunscreen generously to all exposed areas of your body, and reapply frequently, especially after swimming or sweating.
- Seek shade: When outdoors, seek shade under trees, umbrellas, or other structures to minimize direct sun exposure.
- Stay hydrated: Drink plenty of water to keep your body cool and maintain proper hydration.
- Be cautious with medications: Some medications can increase your skin's sensitivity to sunlight, making you more susceptible to sunburn. If you are taking any medications, check for potential side effects and take extra precautions.
- Be mindful of reflective surfaces: Water, sand, and snow can reflect UV rays, increasing your exposure. Be especially cautious when spending time near these surfaces.
- Protect children: Babies and children have delicate skin and are more susceptible to sunburn. Keep young children out of direct sunlight, and use sunscreen formulated for their sensitive skin.
- Avoid tanning beds: Tanning beds expose your skin to high levels of UV radiation, increasing the risk of sunburn and skin damage. Opt for sunless tanning methods instead.
By following these preventive measures, you can effectively reduce your risk of sunburn and protect your skin from the harmful effects of UV radiation.

Treating sunburn with home remedies
Sunburns are caused by exposure to the sun's UV rays or artificial UV light sources. While first- and second-degree sunburns can usually be treated at home, third-degree sunburns are rare and require emergency treatment. Here are some home remedies to treat mild sunburn:
Cool Water
Briefly immersing yourself in cool water, such as a bath, shower, or natural body of water, can help ease discomfort and cool down the affected area. Avoid using cold water, as it may not be as effective.
Moisturizers and Topical Treatments
Applying moisturizers containing aloe vera can help soothe the skin and encourage wound healing. According to a 2024 research review, aloe vera promotes wound healing faster than other antimicrobial agents in people with second-degree sunburns. Additionally, some people recommend using chamomile tea to soothe mild sunburn. Brew the tea, let it cool, soak a washcloth in it, and apply it to the affected area. However, it's important to note that an allergic reaction to chamomile is possible.
Colloidal Oatmeal Baths
Soaking in a colloidal oatmeal bath can help alleviate discomfort and provide a soothing effect on the skin.
Breathable Clothing and Hydration
Wearing breathable clothing can help prevent further irritation and allow the skin to heal. Additionally, staying hydrated by drinking enough water is crucial for overall health and can aid in the healing process.
It's important to note that severe sunburns, especially those accompanied by symptoms like dehydration, fever, blisters, facial swelling, headache, dizziness, or an upset stomach, require medical attention. A doctor may recommend antibiotic ointments, IV fluids, or prescription medications to address more serious cases of sunburn and prevent infection.
