Sunburn is a common skin issue that many people experience after prolonged exposure to the sun’s harmful UV rays. It can cause redness, swelling, and pain, making it essential to find effective ways to alleviate discomfort and promote healing.
One widely debated method for treating sunburn is taking a cold shower, which may provide some immediate relief but could also potentially exacerbate the issue depending on the severity of the burn and the individual’s skin type.
Cold showers have been known to offer a variety of health benefits, but in the context of sunburn, the cooling effect can help soothe inflamed skin and reduce feelings of heat and discomfort.
However, it is crucial to keep in mind that cold showers may not be suitable for everyone, and their effectiveness in treating sunburn will vary from person to person. It is essential to consider the potential risks and benefits before using cold showers as a remedy for sunburn.
Benefits of Cold Showers on Sunburn Relief
Soothes Pain
The cold water in a cold shower can help to numb the pain of a sunburn. This is because cold water can help to reduce the transmission of pain signals from the skin to the brain.
Pain is the body’s way of telling us that something is wrong. It is caused by the release of chemicals called pain neurotransmitters. These chemicals travel along nerve fibers to the brain, where they are interpreted as pain.
One study on cold exposure [1] demonstrates that cold water therapy effectively slows sensory nerve conduction velocity (NCV), thereby reducing pain perception. Initially, the cold temperature constricts dilated blood vessels, which may temporarily increase pain but ultimately enhances circulation, leading to a reduction in pain.
Reduces Inflammation
When you get a sunburn, your body releases chemicals called cytokines that cause inflammation. These cytokines can lead to redness, swelling, and pain. Cold water can help to reduce inflammation by constricting the blood vessels in the skin. This helps to reduce the amount of blood that flows to the affected area, which can help to reduce swelling and pain.
Inflammation is a natural immune response, but it can also be harmful if it is not controlled. Cold water can help to reduce inflammation by activating the body’s natural anti-inflammatory pathways. These pathways help to reduce the production of cytokines and other inflammatory chemicals.
Improves Circulation
Cold water can also help to improve circulation to the sunburned area. This is because cold water can help to dilate the blood vessels in the skin. This helps to increase the amount of blood that flows to the affected area, which can help to bring nutrients and oxygen to the skin, which can help it to heal faster.
Circulation is the flow of blood throughout the body. It is important for delivering nutrients and oxygen to the tissues, and for removing waste products. Cold water can help to improve circulation by contracting the heart muscle. This helps to pump blood more forcefully, which can increase blood flow to the skin.
Promotes Healing
Cold water can also help to promote healing of a sunburn. This is because cold water can help to reduce inflammation and pain, which can help the skin to heal more quickly. Additionally, cold water can help to keep the sunburned area clean and free of bacteria, which can help to prevent infection.
Healing is the process of repairing damaged tissue. It involves a number of steps, including inflammation, cell proliferation, and tissue remodeling. Cold water can help to promote healing by reducing inflammation, which can help the body to focus on repairing the damaged tissue.
Prevents Infection
Cold water can help to prevent infection of a sunburn. This is because cold water can help to keep the sunburned area clean and free of bacteria. Additionally, cold water can help to reduce inflammation and pain, which can help the body’s natural defenses to fight off infection.
Infection is the invasion of the body by harmful bacteria or viruses. It can cause a variety of symptoms, including redness, swelling, pain, and fever. Cold water can help to prevent infection by washing away bacteria and keeping the skin clean.
Risks of Cold Showers on Sunburns
Increased Discomfort
Cold showers can sometimes provide relief to sunburned skin due to their cooling effect. However, in some cases, they may actually cause increased discomfort.
Exposing sunburned skin to cold water can lead to a sensation of stinging or burning, as it may irritate the already inflamed skin. It is essential to pay attention to how your skin feels while showering – if it causes more discomfort, consider switching to cool baths or showers [2] instead. Make sure the water temperature is neither too hot nor too cold to avoid causing further irritation to your sunburn.
Dryness and Itching
Another risk associated with cold showers on sunburns is the potential for increased dryness and itching. While cold water can help soothe the skin, it can also strip away the skin’s natural oils, which help to keep it moisturized. As a result, the skin may become dry and itchy, which can exacerbate the existing symptoms of a sunburn.
To avoid this, after taking a cool shower or bath, gently pat your skin dry instead of rubbing it, and apply a moisturizing lotion or cream, specifically formulated for sunburns, to the affected areas. This will help keep your skin hydrated and alleviate itching while aiding in the healing process.
How Long of a Cold Shower is Recommended for Sunburns?
Dermatologists do recommend taking frequent cold showers, or cold baths, when sunburnt [3]. However long durations in cold water can also dry out your skin. Pat drying and moisturizing will be help retain moisture.
A cold shower for sunburn relief should typically last between 5-10 minutes. This time frame allows the skin to cool down and helps to prevent further damage while avoiding excessive exposure to cold water. Prolonged cold showers might cause the skin to become too dry, which can be counterproductive for sunburn healing.
While taking a cold shower, it’s essential to avoid using harsh soaps or scrubbing the skin aggressively. Sunburned skin is sensitive and prone to irritation; therefore, it’s best to use a gentle cleanser and apply it with a soft washcloth or your hands. Pat your skin dry with a clean, soft towel instead of rubbing it to minimize irritation further.
Aside from cold showers, other measures can help soothe sunburned skin and promote healing. These include applying aloe vera gel, hydrating the body by drinking plenty of water, and wearing loose, breathable clothing. It’s also crucial to refrain from exposing the sunburned area to direct sunlight until it has fully healed.
Is a Hot or Cold Shower better for Sunburn?
Most sunburns are first-degree burns, and the first step for treating a it is to cool the skin [4]. Cold showers can help ease the heat on the skin, reducing inflammation and providing temporary relief from the pain. On the other hand, hot showers can increase irritation and worsen the sunburn, as they can strip the skin of its natural oils, which are essential for the skin’s healing process.
Additionally, cold showers have a vasoconstrictive effect on the blood vessels in the skin, which minimizes redness and swelling, while hot showers have a vasodilative effect that can further promote inflammation. It’s important to note that the water should not be too cold, as an extreme temperature can cause shock or discomfort. Instead, aim for a lukewarm or slightly cool shower to alleviate sunburn symptoms.
When showering with a sunburn, it’s also essential to be gentle with the skin. Avoid using harsh soaps or scrubbing, as this may cause further irritation. Instead, opt for mild cleansers specifically designed for sensitive skin, and gently pat your skin dry with a soft towel rather than aggressively rubbing it.
In addition to cool showers, other remedies can help soothe sunburned skin. Applying aloe vera gel, over-the-counter creams with hydrocortisone, and cold compresses can provide relief, while staying hydrated and avoiding further sun exposure will aid in the healing process.
Cold Plunge or Ice Bath for Sunburns
Cold showers and ice baths have been used for various health benefits and recovery techniques. However, when it comes to sunburns, it is essential to understand how they may help alleviate pain and discomfort.
Using cold water on sunburned skin can provide temporary relief by reducing inflammation and soothing the burned area. The cold temperature constricts blood vessels, which may help decrease swelling and redness. It is also believed to numb the sunburned area, providing relief from the pain and itching sensation.
To reap the benefits of a cold plunge or ice bath for sunburns, follow these steps:
- Fill a bathtub with cool water: Avoid using ice-cold water, as it can shock the skin and potentially cause further damage. Stick to cool water, which is more gentle on sunburned skin.
- Add some soothing ingredients: Epsom salts or baking soda can help alleviate pain and itchiness from sunburns. Add a few cups of either ingredient to the bath, and allow it to dissolve before stepping in.
- Do not expose the sunburned skin to hot water: As tempting as it may be to relax in a hot shower or bath, doing so can actually worsen sunburn symptoms. Stick to cooler water for the time being.
- Moisturize after your cold plunge or ice bath: Gently pat your skin dry with a clean towel and apply a hydrating, fragrance-free lotion or aloe vera gel to keep the skin moisturized and promote healing.
However, it is important to remember that while a cold plunge or ice bath might offer temporary relief for sunburned skin, it does not directly contribute to the healing process. It is essential to focus on sunburn prevention by wearing sunscreen, protective clothing, and avoiding sunburn exposure during peak hours to maintain skin health.
Additionally, staying hydrated and moisturizing the sunburned area are crucial for proper healing and recovery.
Other Benefits of Cold Showers on Skin
The benefits of cold showers go way beyond their potential to alleviate sunburn. Incorporating cold showers into one’s daily skincare regimen can significantly improve skin’s appearance and health. Cold showers are known to tighten the pores on the skin, reducing the likelihood of dirt and bacteria clogging them. As a result, this simple change in shower routine may help prevent acne and other skin irritations.
In addition to tightening pores, cold showers can also improve circulation. When the skin is exposed to cold water, blood vessels near the surface constrict, encouraging blood flow throughout the body. This increased circulation can enhance skin’s overall appearance, providing a healthy and radiant glow. Furthermore, enhanced circulation can aid in the healing of sunburn and other skin damage by delivering essential nutrients more efficiently.
Another benefit of cold showers is their ability to hydrate the skin. Hot water tends to strip the skin of its natural oils, leaving it feeling dry and rough. In contrast, cold water helps to retain these oils, promoting healthy, moisturized skin. This can be particularly beneficial for those with dry or sensitive skin, as it may help alleviate redness and irritation.
