As long as you're a living, breathing human being, you're going to experience stress at some point in your life—it's your body's reaction to a challenge or demand, according to MedlinePlus.

It's a completely normal feeling, and it may even be good for you at times (think: helping you to avoid dangerous situations). But when it lasts for a long time, it can put you at risk for some pretty serious health issues, like high blood pressure, depression or anxiety, and even chronic skin issues.

Though you might know a few of your specific stress triggers—like work deadlines or fights with your spouse—it could be sneaking into your life in other unexpected ways. Here, 21 different things in your life that could be causing you unnecessary stress.

Your significant other

Even if you have a blissfully happy relationship with your live-in partner or spouse, you're both bound to do things that get on each other's nerves. "Early in the relationship, it's usually about space and habits—like whether you squeeze the toothpaste from the middle or the bottom of the tube," Ken Yeager, PhD, associate professor of psychiatry at the Ohio State University Wexner Medical Center, tells Health. "Later on, you might clash over parenting style or financial issues, and finding a unified front to face these issues together."

So what's the key to surviving and thriving in your life together? Finding balance, says Yeager: spending the right amount of time together (not too much and not too little), making compromises, keeping communication open and honest, and remembering to acknowledge what you love about each other on a daily basis.

Everyday annoyances

We're told not to sweat the small stuff, but sometimes it's the little things that have the biggest impact on our mood: the never-ending phone calls with your insurance company, the rude cashier at the grocery store, the 20 minutes you lose looking for a parking space. "We let these things bother us because they trigger unconscious fears," says Yeager—fears of being seen as irresponsible, of being bullied or embarrassed, or of being late all the time, for example. "Sometimes you need to take a step back and realize that you're doing the best you can given the circumstances."

Other people's stress

Stress is contagious, according to a 2014 German study: In a series of experiments, most participants who simply observed others completing a stressful task experienced an increase themselves in production of the stress hormone cortisol—a phenomenon known as empathic stress. You can also experience stress when someone you know is affected by a traumatic event, like a car crash or a chronic illness. "You start to worry, 'Oh my gosh, could that happen to me?'," says Yeager. "We tend not to think about these things until they hit close to home."

Social media

It may seem like Facebook or Instagram are the only ways you keep up with the friends you don't see regularly—which, during particularly busy times, can be just about all of them. But social networks, like Facebook specifically, can also have a downside, according to a 2015 study from the Pew Research Center: It can make you aware of stressful situations in your friends' lives, which in turn can add more stress to your life. The Pew report didn't find that social media users, overall, had higher levels of stress, but previous studies have suggested that frequent social-media use can be associated with negative body image and prolonged breakup pain.

Distractions

A distraction can be a good thing then when it takes your mind off of a stressful situation or difficult decision, like when you take a break from work to meet a friend for lunch. But it works the other way, as well: When you're so busy thinking about something else that you can't enjoy what's going on around you, that kind of distraction can be a recipe for stress.

Practicing mindfulness gives you brain the refresh it needs, says Richard Lenox, director of the Student Counseling Center at Texas Tech University. Paying full attention to your surroundings when you're walking and driving can help, he adds. "Stress and anxiety tend to melt away when our mind is focused on the present."

Your childhood

Traumatic events that happened when you were a kid can continue to affect your stress levels and overall health into adulthood. A 2014 University of Wisconsin-Madison study found that these childhood experiences may actually change parts of the brain responsible for processing stress and emotion. The way you were raised can also have a lasting impact on your everyday angst, suggests a 2014 Johns Hopkins University study. Researchers found that children of parents with social anxiety disorders are more likely to develop "trickle-down anxiety"—not simply because of their genes, but because of their parents' behaviors toward them such as a lack of warmth and emotion, or high levels of criticism and doubt.

Tea and chocolate

You probably know to take it easy on the coffee when you're already feeling on edge. "Caffeine is always going to make stress worse," says Yeager. But you may not think as much about drinking several cups of tea at once, or chowing down on a bar of dark chocolate—both of which can contain nearly as much caffeine as a cup of joe. "Chocolate is a huge caffeine source," says Yeager. "I know people who don't drink coffee but they'll eat six little candy bars in a two-hour period because they want the same kind of jolt." Too much caffeine, in any form, can cause problems with sleep, digestion, and irritability.

Your expectations

When things don't go the way you've planned, do you tend to get upset and act defensively, or do you roll with the punches and set off on a new plan? If it's the former, you could be contributing to a mindset of pessimism and victimization that will slowly wear you down, even when things may not be as bad as they seem. "Your level of serenity is inversely proportionate to your expectations," says Yeager. That doesn't mean you shouldn't set ambitious goals for yourself or settle for less than what you want, of course, but being realistic about what's truly possible is important, as well.

Your reaction to stress

If you tend to deal with stressful situations by working long hours, skipping your workouts, and bingeing on junk food, we've got some bad news: You're only making it worse. "We know that physical activity and healthy foods will help your body better deal with stress, and yet we often avoid them when we need them the most," says Yeager. "People really need to think about this downward spiral we get into and work harder to counteract it."

Multitasking

Think you're being super efficient by tackling four tasks at once? Chances are you're not —and it's only decreasing your productivity while increasing your stress. A 2012 University of Irvine study, for example, found that people who responded to emails all day long while also trying to get their work done experienced more heart-rate variability (an indicator of mental stress) than those who waited to respond to all of their emails at one time. Focusing on one task at a time can ensure that you're doing that job to the best of your abilities and getting the most out of it, so you won't have to worry about or go back and fix it later, says Schieman. And don't worry: You'll have enough time to do it all. In fact, you may discover you have more time than you thought.

Your favorite sport

Watching a tight game of college hoops can stress you out—even if your alma mater wins. "The body doesn't distinguish between 'bad' stress from life or work and 'good' stress caused by game-day excitement," says Jody Gilchrist, a nurse practitioner at the University of Alabama at Birmingham's Heart and Vascular Clinic. Watching sports can even trigger the body's sympathetic nervous system, releasing adrenaline and reducing blood flow to the heart. Those temporary consequences aren't usually anything to be concerned about, but over time, chronic stress can lead to high blood pressure and increased disease risk. And, of course, it doesn't help if you're adding alcohol and binge-eating to a situation that's already stressful on your body. You may not be able to control the outcome of the game, says Gilchrist, but you can limit its effects on your own body.

Digital devices

Whether you're using it for work or play, technology may play a large role in your mental health, says Yeager. Using computers or e-readers too close to bedtime could lead to sleep problems, he says, and spending too much time virtually socializing can make real-life interactions seem extra stressful. (Plus, texting doesn't trigger the same feel-good hormones as face-to-face talk does.) Then there's the dreaded "work creep," says Schieman, when smartphones allow employees to be tethered to their jobs, even during off-hours. "People say they're only going to check email for an hour while they're on vacation, but the problem with email is that they're filled with responsibilities, new tasks, and dilemmas that are going to be hard to compartmentalize and put out of your head once that hour is up."

Your (good) health

While it may not be as stressful as having a chronic illness or getting bad news at the doctor's office, even people in the best shape of their lives worry about their bodies, their diets, and their fitness levels. In fact, people who take healthy living to an extreme may experience some rather unhealthy side effects. People who follow low-carb diets, for example, are more likely to report being sad or stressed out, while those on any kind of restrictive meal plan may feel more tired than usual. And it's not unheard of for someone to become obsessed with healthy eating (known as orthorexia) or working out (gymorexia). Like any form of perfectionism, these problems can be stressful at best, and extremely dangerous at worst.

Housework

Does folding laundry help you feel calm, or does it make your blood boil? If you're in a living situation where you feel you're responsible for an unfair share of work, even chores you once enjoyed may start to feel like torture. "Dividing up housework and parenting responsibilities can be tricky, especially if both partners work outside the home," says Schieman. "And whether you define that division of labor as equal or unequal can really change your attitude toward it."

15 of 21

Uncertainty

Stress can be defined as any perceived or actual threat, says Yeager, so any type of doubt that's looming over you can contribute to your anxiety levels on a daily basis. "When you know something could change at any minute, you always have your guard up and it's hard to just relax and enjoy anything." Financial uncertainty may be the most obvious stressor—not being sure if you'll keep your job during a round of layoffs, or not knowing how you'll pay your credit card bill. Insecurities in other areas of life, like your relationship or your housing status, can eat away at you too.

Your pet

No matter how much you love your furry friends, there's no question that they add extra responsibility to your already full plate. Even healthy animals need to be fed, exercised, cleaned up after, and given plenty of attention on a regular basis—and unhealthy ones can be a whole other story. "Pets can be the most positive source of unconditional love, but at the same time they require an extreme amount of energy," says Yeager. People also tend to underestimate the stress they'll experience when they lose a pet. "I've had people in my office tell me they cried more when their dog died than when their parent died. It's a very emotional connection."

Your education

Having a college degree boosts your odds of landing a well-paying job, so although you're less likely to suffer from money-related anxiety, your education can bring on other types of stress, according to a 2014 study by Schieman and his University of Toronto colleagues. His research found that highly educated people were more likely to be stressed out thanks to job pressures, being overworked, and conflicts between work and family. "Higher levels of authority come with a lot more interpersonal baggage, such as supervising people or deciding whether they get promotions," says Schieman. "With that type of responsibility, you start to take things like incompetency and people not doing their jobs more personally, and it bothers you more."

Noise

If you live on a noisy street or a busy city, you're dealing with sound on the regular. Research has found that chronic low levels of noise can lead to things like trouble sleeping, which can then trigger stress. Noise can also directly stress you out if you're conscious of it (because, hello, who likes to go about their day to the soundtrack of jackhammers?). "What tends to be the most stressing is noise that's less predictable and high-pitched," psychologist Frank Ghinassi, PhD, president and CEO of Rutgers University Behavioral Health Care, tells Health. So basically, any noise you'd hear in an urban setting. "It can be frustrating to concentrate and that can lead to more energy to work against that frustration," he says. Noise specifically triggers a stress response in your amygdala, the part of your brain that regulates emotion, psychologist John Mayer, PhD, host of the Anxiety's a B!tch podcast, tells Health. "Your amygdala learns over time what sounds might signal impending danger," he explains. "When one is detected, the amygdala triggers a release of cortisol." Cue the stress.

Pandemic life

How to Deal With the Emotional Fallout From a Mass Shooting Incident , BOULDER, CO -MARCH 23: From left to right: Nirbisha Shrestha, Sophia Kennedy, and Josie Elowsky, all 19, are emotional as they hug near the fence surrounding the King Soopers on Table Mesa Drive on March 23, 2021 in Boulder, Colorado. The four went to high school in Boulder and spent almost every lunch hour at the King Soopers. Hundreds of people turned out late in the day to pay their respects to those that lost their lives by a gunman who opened fire inside the grocery store. People stayed well into the dark to drop off flowers, light candles, hug one another and to show their respects for the ten victims of the mass shooting. (Photo by Helen H.

It's easy to put your head down and assume you're doing just fine while living through a global pandemic. But Mayer says it's pretty tough not to be stressed out by at least some element of the COVID-19 crisis, whether it's annoyance at missing out on things that you used to do, worries about job security, or an actual fear of contracting COVID-19. "The very first defense mechanism that a human develops is denial," Mayer says. "When stressors appear to be far removed from our lives, we employ this basic response of denial first." You may be able to continue living in denial if you or someone close to you doesn't directly suffer from a consequence of the pandemic, he says, but the stress is still there. The problem with this is that the stress can build over time, making you feel even more frazzled as you go, Ghinassi says.

Complaining

On the one hand, you're getting out all those thoughts you have bottled up inside; On the other, you're rehashing things that are already bothering you, raising the odds it'll just upset you all over again. At its core, venting involves "discharging negative thoughts and feelings," Mayer says. But by doing that, you're consciously being reminded of the negativity. That "rekindles the fears and worries from the original events," Mayer says. Ghinassi suggests reframing the way you vent and trying to cast things in a less terrible way. One example: Calling something "annoying," which implies that you can live with it, vs. "awful," which sounds borderline catastrophic.

Alcohol

Martini-10-Lowest-Calorie-Alcoholic-Drinks

Sure, sometimes having a glass of wine after a long day can help you mentally chill out. But sometimes it can work against you. Alcohol actually causes higher levels of the stress hormone cortisol to be released in your body—and that can make you feel more stressed out after you come down from your buzz. There's also this to consider, per Mayer: If you drink a little too much, you can struggle with things like memory loss and poor judgement, and that's not going to do your stress levels any favors, either.
