Travis FullerModerate stress is good for you when it comes in short bursts. It sharpens your focus, pushes you toward other people, gets your immune cells moving and builds the confidence and resilience you need for the next hard thing. Stress that never lets up is the kind that hurts.

Not all stress is the same. Most of us have felt our heart pound before a big test or a job interview. Most of us have also lived through the kind of stress that hangs around for weeks. A lot of anxiety and stress is hard to deal with, and it can lead to many physical problems that hurt your overall health. Too much stress, for instance, can cause fatigue, high blood pressure and sadness or depression, according to Mayo Clinic. But don’t assume those problems are certain to follow if you’re going through a rough stretch of stress. We can’t control how many stressful situations show up in our lives, but we can control our own outlook toward them. Stress doesn’t have to be the enemy. Oddly enough, your own mind is often your worst opponent.
How you think about stress may matter, too. A study in Health Psychology in 2012 followed 28,753 U.S. adults from a 1998 national health survey. People who reported a lot of stress and believed it hurt their health a lot had a 43% higher risk of dying early. Psychologist Kelly McGonigal, describing the study in her TED talk, said the people who experienced a lot of stress but did not view it as harmful were no more likely to die early than people who led a relatively low-stress life.
Stress is your body’s built-in defense against risky, uncertain situations. It wakes you up and gives your body energy to handle tough moments. Is your heart pounding? That means more blood is moving through your body, getting you ready to act. Are you breathing faster? That’s your body’s way of getting more oxygen to your brain, and Harvard Health says that extra oxygen makes you more alert. In this article, we’ll look at ways to see stress in a positive light, so you can treat it as a plus overall and help your body rise to the big challenges.
Stress pushes you toward other people
Have you ever heard of the hormone oxytocin? It’s a brain hormone that fires up your social instincts and your drive to build strong, lasting relationships. It can boost empathy and make you want physical contact with close friends and loved ones. It’s also, surprisingly, a stress hormone.
When you’re thrown into a stressful situation, your pituitary gland releases oxytocin. That signals your brain to start looking for support, friendship and community. It seems your body is built to know it can’t get through every hard thing alone. When something goes wrong, most of us reach for the phone and call a friend. When life hands you a lemon, don’t worry: your body sends a rush of oxytocin and an urge to find comfort.
UCLA psychologist Shelley Taylor built her tend-and-befriend model partly on oxytocin’s role in stress, as the Association for Psychological Science reported. In animal studies, injected oxytocin lowered anxiety and increased grooming, touching and bonding. A review of 26 studies found all but one showed women reaching out for social support under stress.
A little stress can sharpen your brain
If you’re nervous about something coming up, don’t worry too much: your body is set up to respond. Say you’re scheduled to give a speech in front of a big audience. You feel a little uneasy about speaking in public, but you agree to do it, deciding firmly that the possible benefits are worth the risk of it going badly.
If your stress is moderate, not extreme, your brain can perform better. At UC Berkeley, Daniela Kaufer and Elizabeth Kirby briefly stressed adult rats for a few hours. New brain cells in the hippocampus, a part of the brain involved in memory, formed at double the normal rate, and the rats did better on a memory test two weeks later, per the 2013 study in eLife. Kaufer’s take is that stressful events now and then probably keep the brain more alert, and you perform better when you are alert. If you can keep your stress in check, the odds are very high that you’ll get your message across.
That’s why many employees often work better when a surprise pile of last-minute assignments lands on their desk. Anyone who’s crammed the night before a test knows how much gets done when the deadline is close. The short time between getting the assignment and the deadline pushes workers past obstacles they once thought they couldn’t handle.
Here’s a suggestion: keep a work journal and note what you do each day. It can leave you feeling good about everything you got done, and you may also notice a pattern of doing your best work when you’re handed a tougher workload. Remember, luck is where preparation meets opportunity.
Short stress and your immune system
It may seem backward, but keeping your stress in check can be a big plus for your overall health. Short-term stress can put your immune system on alert. In a 2012 Stanford study led by Firdaus Dhabhar, mild stress in rats caused a big rush of key immune cells into the bloodstream within about two hours. Those cells then moved into tissues like the skin. Chronic stress that lasts weeks or months does the reverse and holds the immune response back.
That’s the line to watch. Mayo Clinic lists getting sick more easily, due to a weaker immune system, among the effects of stress. A tough week isn’t the problem. Stress that becomes the way you live all the time is. So it pays to change how you think about stress and life’s daily burdens, and to see an obstacle as something you can work with rather than something to dread.
Getting through hard things builds resilience
Nobody is eager to take on problems that are tough, even impossible, to fix. But how you see them and how you react is what builds personal resilience, determination and staying power. The American Psychological Association defines resilience as adapting well in the face of adversity, trauma, tragedy, threats or big sources of stress. It also says resilience isn’t a fixed trait. It’s made of behaviors, thoughts and actions anyone can learn, and it suggests thinking back on who and what helped during earlier hard times.
Most people can look back at something that felt impossible at the time and is now just a story they tell. Getting stronger takes time. Maybe you’re going through a divorce or you’ve just lost a job, and some days feel really heavy. Leaning on the people around you, and on strengths you already have, can help you find your footing again or a new direction. The next time life gets hard, you’ll remember how you got through it, and it may feel a little less overwhelming. If low moods hang on or start to feel like too much, talking with your doctor or a counselor is a good next step.
In short, getting through stress well can build character.
Manageable stress builds confidence
If you can keep your stress in check, the stress that’s bound to show up can actually boost your confidence. When a challenge is clearly doable, well within what’s possible, we feel a positive form of stress called eustress.
Say you have to prepare a report and present it to your supervisor for approval. You feel extremely well prepared, with all the basics you need to defend your proposal. You’ll likely feel eager about the meeting, sure that it will pay off. Anyone who’s walked into a meeting fully prepared knows it feels different from walking in cold. You’ve turned stress to your advantage, using it as a tool for success instead of letting it get in your way.
When stress stops being moderate
Mayo Clinic lists the signs: headaches, muscle tension, chest pain, stomach upset and sleep problems; anxiety, trouble focusing and feeling overwhelmed; and overeating or undereating, angry outbursts and avoiding friends. It says stress that isn’t dealt with can lead to high blood pressure, heart disease, stroke, obesity and diabetes. Its fixes are simple: move most days, try deep breathing or yoga, get enough sleep and spend time with family and friends.
MedlinePlus says to contact your health care provider if you feel overwhelmed by stress or it’s affecting your health. If you or someone you know is thinking about suicide, call or text 988 right away.
Is moderate stress good for you? FAQ
Is moderate stress actually good for you?
In short bursts, yes. MedlinePlus says stress can be positive when it helps you avoid danger or meet a deadline, because it makes your brain more alert and raises your pulse. Research on short-term stress in rats at UC Berkeley and Stanford found it sparked new brain cells and moved immune cells into action. Stress that drags on for weeks is the kind that hurts.
How do you know if stress has become too much?
Mayo Clinic lists the common signs: headaches, muscle tension, stomach upset and sleep problems in your body; anxiety, trouble focusing and feeling overwhelmed in your mood; and overeating or undereating, angry outbursts and avoiding friends in your behavior. MedlinePlus says to contact your health care provider if you feel overwhelmed by stress or it is affecting your health.
Does stress weaken your immune system?
It depends on how long it lasts. A 2012 Stanford study in rats found that short-term stress sent several key types of immune cells into the bloodstream and on to tissues like the skin. Chronic stress lasting weeks or months does the opposite. Mayo Clinic lists getting sick more easily, due to a weaker immune system, among the effects of stress.
Does believing stress is bad for you make it worse?
One large study suggests it might. Researchers who followed 28,753 U.S. adults from a 1998 national health survey, published in Health Psychology in 2012, found that people who reported a lot of stress and believed it affected their health a lot had a 43% higher risk of dying early. How you read your stress seems to matter.
