Always wear sunscreen, stay hydrated, and try to avoid direct sunlight when it’s super hot outside. It’s the middle of the summer right now and one of the biggest joys for many folks is soaking up some rays and stocking up on vitamin D. Sunlight is important for our physical and mental health, but too much ultraviolet light can be harmful, painful, and… embarrassing.

To remind you to prioritize your health when it’s sunny (and to give you a hearty laugh), our team here at Bored Panda has collected some of the biggest sunburn fails from all over the net. The photos show what happens when you forget to put on sunscreen, miss a spot, or if you wear hats and clothing with cut-out shapes in the fabric.

Scroll down, upvote the pics that you found the funniest, and tell us about the worst sunburn you’ve ever gotten in the comments. Meanwhile, you’ll find Bored Panda’s earlier list about the most hilarious sunburns over here.

Just remember: stay safe; don’t be lazy, don’t be stubborn, and put on some darn sunscreen!

Dr. Andrew Carroll, the CEO/Medical Director of Atembis LLC and Family Physician, was kind enough to share his expertise with Bored Panda. He explained why it's important to get daily sunlight, how we can tell when we're going overboard, and how to convince someone to protect themselves from the sun's rays. You'll find the expert's insights as you scroll down.

Dr. Carroll, the head of Atembis LLC, said that everyone should get a decent amount of sun daily. "We need sunlight just for mental health, but we also need it to help convert vitamin D to its active form. Taking vitamin D orally is not enough—it needs to be activated and that happens through the skin. There is no “right amount” of sunlight. Everyone’s skin tone is different," the medical expert said.

"What you don’t want to do is burn. If you get a peeling sunburn, each time that happens, you’ve increased your risk of skin cancer. Excessive sun exposure also increases the risk of solar lentigo, which are sunspots," the doctor warned. "A peeling, blistering sunburn is 'too much.' You don’t want to get there."

Meanwhile, sunstroke is different. It's a state of dehydration: it occurs when you don't consume enough fluids while you're out in the hot sun. Recently, Europe has been dealing with a massive heatwave, so both sunstroke and sunburns were much more acute.

"Your skin requires hydration to stay healthy—if you’re outside for long periods of time, make sure you’re hydrating from the inside as well as the outside by using lotion and/or protective sunscreen," Dr. Carroll told Bored Panda.

We wanted to get the doctor's opinion on how someone could go about talking with a person who stubbornly refuses to wear sunscreen. Here's what he told us: "Sometimes the best way to convince someone of the risks of too much sun exposure is to have them talk to older relatives. Older relatives not only share genetics but also commonly skin tone and risks tend to be similar. Talk to your older relatives and look at their skin."

Dr. Carroll, of Atembis LLC, shared with Bored Panda the types of questions that people should ponder: "Do they have a lot of sunspots? Look at their hands. Look at the skin structure. Is it leathery and thick, wrinkled early? Is it overly thin and easy to tear? How many times have they had something cut or frozen off of their skin? Have they ever had major surgery for skin cancer? Those risks are shared, and you can reduce your own risk by either using physical cover or wearing sunscreen appropriate to your skin tone," he said. Physical cover includes clothing, hats, and sunglasses, the latter of which reduces the risk of cataracts.

Sunlight is pretty much like anything else—moderation is key, and the ‘dose’ you get really matters. Sunlight helps with serotonin production and helps you stay calm, focused, and positive; it also gives you more energy. It’s also one way to fight back against depression and seasonal affective disorder. So much so that some doctors prescribe natural or artificial light treatments.

In other words, you need a daily dose of sunlight to be a properly functioning human being. You really shouldn’t spend all day indoors, in front of your computer screen, hissing at anyone who opens the curtains. On the flip side, you don’t want to stay out in the sun for too long. Especially without protection.

Some people are naturally more prone to getting sunburnt. The easiest way to predict the future is to look at the past. Have you gotten badly sunburnt in the past? Do you end up looking like a super-red lobster after just a few minutes outdoors? Do people keep telling you to put on sunscreen, for the love of all that’s holy? Those are some ‘subtle’ hints that you should be far more careful with your skin health during the summer and throughout the year.

According to the Mayo Clinic, people who have white skin and red hair are at higher risk of getting sunburn. Obviously, if you’re at the beach or elsewhere with tons of sun, the risk is higher, too. But those of you traveling to the mountains and places at a high altitude should also be aware that your skin might get burnt more easily.

Wet skin tends to burn more easily than dry skin, so keep that in mind when splashing around in the sea, lake, or pool this year. You might want to invest in lots of water-resistant sunscreen if you plan to do a lot of swimming.

Of course, sunscreen isn’t the only way to protect yourself. You can wear long-sleeved clothing and hats to protect yourself from the UV rays. If your skin feels painful or hot to the touch, odds are that you’ve gotten a sunburn, and it should appear within a few hours. It can several days to heal.

Prevention is usually better than having to deal with the consequences. However, we can’t always avoid those. When you get a sunburn, your skin might look pink or red, it might feel tender and itchy. There might be swelling and blisters, and you might have a headache or a fever. The scariest thing is that even your eyes can burn in the sun.

If the pain gets worse, your headache or fever doesn’t break, head to the doctor ASAP. You should also seek medical help if you get blisters on your face or hands, or if your blisters show signs of infection. Getting chills and noticing changes in your vision are also signs that you need may need assistance from a professional.

The NHS warns not to use petroleum jelly or ice on sunburnt skin. What’s more, you shouldn’t scratch the affected area; don’t pop any blisters, and avoid wearing tight-fitting clothes while your skin is peeling and healing.

You can actually get sunburnt on cloudy days. Meanwhile, water, sand, and even snow reflect UV rays and add to the risk of getting burnt badly. As the UV light damages your skin cells, your body reacts by increasing the blood flow to the affected areas. That’s what causes the skin to be inflamed.

Meanwhile, sun exposure ages your skin more quickly and you’re more likely to develop wrinkles and discolored spots. Your skin loses strength and elasticity. Moreover, the more time you spend out in the sun, the greater the risk of skin cancer. That’s why it’s so important to do everything that you can to stay protected. Your health is your greatest resource, Pandas. Protect it well while you’re enjoying life to the max.
