Having an allergy is pretty common. Many people are allergic to peanuts or pollen or pets. Common allergies like those can be pretty easy to manage, but some people have allergies that completely alter their lifestyles.
From water to electricity, people can be allergic to everyday things we never think twice about.
Check out some of these allergies and the people they affect below:
Yep, that's right. You can be allergic to the thing that makes up almost 60 percent of your body. A 17-year-old in Utah is one of the few people diagnosed with an allergy to water. When she was 12, she went swimming only to wake up in the middle of the night covered in hives.
"I remember sitting in the bathroom trying so hard not to scratch myself and make it worse until my mom came back with the Benadryl," the teen told ABC News.
Exposure to water can cause hives and a rash. Getting wet in any capacity can cause a reaction, from showering to crying.
2. All foods
For the past four years, another Utah teen has been unable to eat anything. He's developed an allergy to the proteins found in foods, which makes it impossible to eat anything. If he does, he'll have to deal with hives, fatigue, stomach pain, nausea and headaches for days.
"I can't even put something in my mouth just to taste it and that's hard because I remember what food tastes like," the teen told People. "The sight of food and the smell of food — especially something I used to love — can make me crave it. But I don't want to feel miserable."
He gets his nutrients and calories from a feeding tube that's connected to his stomach.
Imagine never being able to go outside without being covered from head to toe. That's the life people with an allergy to the sun have to lead. One 26-year-old mom has had this condition for her entire life. She experiences skin burns and rashes when she's exposed to UVA and UVB light.
"As soon as I'm exposed to the sun, I feel my skin start to burn and experience a melting feeling on any unprotected skin, which causes intense pain," the mom told Express.
When she's indoors, she has to block out all sunlight with curtains and blinds.
4. The cold
A lot of people hate the cold. Winter can seriously suck. But for some people, it's actually life threatening to just step outside during winter. An allergy to the cold can cause hives, swelling and even anaphylactic shock.
One child from Ontario has an allergic reaction when he experiences temperatures under 50 degrees Fahrenheit. Many people with this allergy can't go outside during winter, drink iced beverages or swim in cold water.
A 55-year-old British woman has to live a life isolated from electricity. She experiences chest pains, headaches, nausea, and tingling in her arms and legs when she's in close proximity to electrical devices or signals.
"Different things give me different feelings but it's mostly headaches and nausea," she told The Telegraph. "iPhones make [me] feel really sick within about 20 minutes of being near one. Wi-Fi makes me feel like I have a clamp at the back of my head which is squeezing the life out of me."
She can't watch television, talk on a cellphone or even live near neighbors with Wi-Fi.
"Every time we had sex, there was immediate pain and a burning sensation," she writes. "The area would become red and swell up, then over the next week the skin cells would shed and fall off. I would be left in agony and the pain lingered for days."
Interestingly enough, some people may be allergic to one partner's semen, but not another.
It's almost too easy to make excuses about why we can't hit the gym, but some people really are allergic to exercise.
One British woman who suffers from this allergy breaks out in hives when she breaks a sweat. Her eyes can swell shut and her throat closes up. "It took me years to realize that exercise was the trigger," she told ABC News. "People don't believe me when I tell them I'm allergic to exercise. They think it's just an excuse to be lazy."
