What to do if you get a sunburn

What to do if you get a sunburn

It’s summer at last. As a kid, summer meant freedom. Freedom from school, from homework, from a schedule. Even as I got older and worked at summer jobs, the change of pace that summer brought was always welcome.

Summer feels that way this year. After so many months of restrictions, we’re finally seeing more than glimmers of hope and much more freedom (especially if you’re vaccinated). Time to get out and enjoy some summer pleasures.

Right now, the sun is at its yearly strongest. Which means that its ability to burn and damage your skin is at its strongest too.

Of course, you should be putting sunscreen on every day year round, but its even more important right now. Daily sunscreen is as important as brushing your teeth.

For me, its as important as my morning coffee.

But it happens to all of us.. You miss a spot with the sunscreen or stay out longer than you’d planned or forgot to reapply after sweating or going in the water.

And you get a sunburn.

I managed to burn my left shoulder (only the left so I must have forgotten to put sunscreen on it), the other day.

It started me thinking about what happens to your skin when you get sunburned. A sunburn isn’t a good thing, but your body’s response to it are pretty amazing.

What actually happens when you get a sunburn?

A sunburn is a radiation burn, which is different from the type of burn you get from touching something hot (thermal burn). The burn from a sunburn isn’t from the heat. It’s from the sun’s UV rays causing cell damage.

Too much exposure to the sun’s rays damage the DNA, cell membranes and some proteins in the upper layers of  your skin.

UVA and UVB rays

Remember, there are two types of rays that can cause damage to your skin. UVB rays penetrate the outer layers) epidermis and UVA rays go deeper to the dermis.

UVA rays penetrate deeper into the skin and can cause the damage that results in photo aging, dry skin, and sagging. You’re generally not aware of this type of damage going on until it’s already done. Remember (UV)A=aging

UVB rays are the sunburn causers. They can penetrate in the skin cell’s DNA and damage it. Repeated DNA damage from too much sun can overwhelm your body’s very capable repair system and cause skin cancer. (UV)B=burn

Your skin mounts an emergency response

Your skin detects the damage and produces proteins that attract immune cells to come and clean up the damage.

Part of this process is that white blood cells and fluids leak into the space between the skin cells. This is what causes the redness and swelling (the ouch) of a fresh sunburn.

This process starts while you are getting burned and increases about an hour later and keeps increasing for 24-48 hours. Which is why it usually feels worse that night or the next day.

Your immune cells start cleaning up the badly damage cells and release chemicals that will further damage already weakened cells. You may have an allergic response to this clean up process that triggers itching.

If there are whole layers of skin cells that have been killed, the dead layer will lift away from the other layers and the space left will fill with the fluid that has leaked from the immune response. Blisters.

Once the inflammation starts to go away, the lower layers of your skin will produce new cells quickly. The dead layers are sloughed off to make way for the new cells and you get peeling.

Finally, to try to protect you in the future, the damaged DNA in the upper layer cells alerts the cells that produce melanin (melanocytes) to get to work and produce a tan.

A tan is your body’s attempt to protect you from further sun damage. But a tan doesn’t give you a lot of protection. It’s about an SPF 2.

So much for getting that first sunburn and your “protective” tan. It’s just doesn’t work like that.

What you can do if you get burned

If you spend time outdoors (and who doesn’t?), chances are you’re going to get a sunburn sooner or later, no matter how careful you are. Here’s what to do:

Rule #1—Get out of the sun. By the time you feel like you’re getting burned, it’s too late. Don’t make it worse.

You can’t undo the sunburn but you can (and should) support your skin and body while it works hard to deal with the damage.

  • A cool shower or bath can cool your skin and help relieve the pain. If you’re taking a bath, you can add cooled chamomile or black tea to sooth your skin
  • A cotton ball soaked in witch hazel can be cooling and soothing. Traditionally, many Native American tribes have used witch hazel to soothe a sunburn.
  • Gently pat yourself dry but leave a little bit of water on your skin. Apply a moisturizer right away to trap the moisture in your skin. This will help keep your skin from getting really dry.
  • For your face, neck, chest or hands, consider applying a vitamin C serum to help your skin deal with the free radicals caused by sun damage. This is no where near as good as putting the serum on before you go out in the sun, but it can help somewhat.
  • Use a moisturizer that has aloe in it.  Bonus points for a formula with antioxidants and/or vitamin C (SunUp or DewDrops for your face).  
  • Do not treat sunburnt areas with heavy greasy products like petroleum jelly (Vaseline) because they can seal in the heat and make matters worse.
  • Don’t use aftersun products with “-caine” products (such as benzocaine). They may irritate your skin or cause an allergic reaction.
  • You can take aspirin or ibuprofen to help with pain and inflammation. If the pain persists, or if you experience a lot of blistering, nausea, fever or dizziness, it’s time to see your doctor.
  • Drink extra water to prevent dehydration.. A sunburn draws fluid to the skin’s surface and away from the rest of your body. This means you need extra water to keep yourself running smoothly.
  • If your skin blisters, don’t pick (however tempting). Allow the blisters to heal. They help protect you from infection while your skin heals.  Blistering skin means you have a second-degree sunburn.
  • Take extra good care of your sunburned skin. The last thing your skin needs right now is more damage. This means a hat to cover your face (and sunscreen, of course) and clothing that covers your skin when you’re outside. Tightly-woven fabrics work best. When you hold the fabric up to a bright light, you shouldn’t see any light coming through

When your skin stops peeling, moisturize the tender new skin and keep it well covered and protected so you don’t get a burn on top of a burn (SO bad).

Then get back out, enjoy the season, and take good care of your skin.
