Pain from a sunburn usually starts within 6 hours and peaks around 24 hours. Pain will usually subside after 48 hours. You can reduce pain with over-the-counter pain relievers such as ibuprofen Motrin, Aleve or aspirin Bufferin.
Shop for ibuprofen or aspirin. Find cold compresses on Amazon. Swelling may persist for up to two days or longer for severe burns. You can take anti-inflammatory drugs like ibuprofen or use a corticosteroid cream to help reduce swelling.
Blisters from a moderate to severe burn start to show up between 6 and 24 hours after UV exposure, but sometimes can take a couple days to show up on the skin. Since blisters are usually the sign of a moderate or severe burn, they might persist for up to a week. Your body made these blisters in order to protect your skin and allow it to heal, so breaking them will slow down the healing process. It also increases your risk of infection.
If blisters break on their own, clean the area with mild soap and water, and cover the area with a wet dressing. Keep the blisters out of the sun to help expedite healing. Once peeling starts, it can last for several days. In general, peeling will stop when the skin is fully healed. For a mild to moderate burn, that should be within seven days , but small amounts of peeling can occur for several weeks.
Be gentle when removing dead skin cells from peeling skin. Your new skin is delicate and more susceptible to irritation. Try taking a warm bath to help loosen the dead cells. Try plain petroleum jelly if needed. A rash can develop within six hours of sun exposure, and it may last for up to three days depending on the severity of your burn.
Apply a cool compress and aloe vera gel to help soothe the skin and make your rash go away faster. If our Sun is four and a half billion years old, how much longer will it shine? Stars like our Sun burn for about nine or 10 billion years. So our Sun is about halfway through its life. It still has about 5,,,—five billion—years to go. When those five billion years are up, the Sun will become a red giant.
That means the Sun will get bigger and cooler at the same time. But in about 5 billion years, the sun will run out of hydrogen. Our star is currently in the most stable phase of its life cycle and has been since the birth of our solar system , about 4.
Once all the hydrogen gets used up, the sun will grow out of this stable phase. With no hydrogen left to fuse in the core, a shell of fusion hydrogen will form around the helium-filled core, astrophysicist Jillian Scudder wrote in an article for The Conversation. Gravitational forces will take over, compressing the core and allowing the rest of the sun to expand. Our star will grow to be larger than we can imagine — so large that it'll envelope the inner planets, including Earth.
People may not realize immediately that they have sunburn, as symptoms usually start around 4 hours after the skin is exposed to the sun.
Sunburn is a sign that the body is trying to repair damaged skin, and this can take time. How long it lasts will depend on how severe the sunburn is:. The immediate symptoms of the skin feeling hot, looking red, and feeling sore, will usually worsen 24—36 hours after exposure to the sun.
Although the immediate effects of sunburn should heal within days or weeks, the damage can have a much longer-lasting impact.
The Skin Cancer Foundation suggests that this damage could be a key cause of melanoma , the most serious form of skin cancer. UVA and UVB rays can also affect the appearance of the skin, causing aging, wrinkles, and brown age spots.
Everyone can be at risk of sunburn, no matter how dark or light their skin tone. However, there are certain risk factors that might make someone more likely to burn. These include:. Babies under the age of 6 months should be kept out of direct sunlight. Someone should seek medical advice if they have burned a large area of the skin on their body, feel unwell, or have any of the following symptoms:. Severe sunburn can sometimes require treatment in a hospital, the application of a special burn creams, or being covered with a dressing.
Sunburn cannot be cured, as the skin has been damaged and will have to heal itself. However, there are some ways to ease the discomfort of sunburn and help the skin to repair. A cool bath or shower, or gently applying a cool, wet cloth to the sunburn, can help to relieve some of the discomfort and begin to take the heat out of the skin.
Drinking extra water can help prevent dehydration, which may result from the body directing more fluid to the skin to help repair the damage that has been done. Applying a moisturizer can soothe the skin and prevent it from drying out.
