Everyone struggles with stress daily, but few know anything about the stress response cycle. Even if you are one of the lucky ones and live a relatively relaxed life, you’ll still experience it to some extent. This happens because stress is a natural hormonal response to uncomfortable or dangerous situations. But what most people don’t know is that the feeling doesn’t just appear out of thin air. You may feel depression or exhaustion, not realizing it stems from your body’s natural responses.

There is a whole stress response cycle that people go through when they are under pressure. And the only way to cope with stress healthily is by completing the cycle. The issue is that people aren’t taught things like these when they are young. Society doesn’t give enough importance to mental health and often regards stress as usual.

While it is natural and beneficial sometimes, it doesn’t mean it’s normal to be cripplingly stressed all the time. But that’s not what people learn. No one teaches others how to cope correctly, and some people even romanticize stress. For example, you have undoubtedly heard people saying that a job isn’t good enough unless it puts some pressure on you to perform. Or maybe your parents have told you that if you aren’t stressed about school or work, that means you don’t care.

Small, off-handed comments like these make it seem normal to be stressed constantly. Not only that, but they lead you to believe that if you aren’t, you should feel guilty. Because of this, people end up developing unhealthy coping mechanisms for stress. As a result, they don’t complete the stress response cycle, which means they never fully relax. This harms both your physical and mental health. Therefore, you must learn about the stress response cycle stages to cope with stress properly.

What Is Stress?

Before going into details about the stress relief cycle, you must understand what stress is and how it can affect you. And the best way to begin is to talk about what causes stress in the first place. Stress is a typical reaction to challenging, demanding, or dangerous situations. In those cases, your body needs to react, and it does so by releasing hormones. These hormones must be present so your body can be alert enough.

It’s a way to adjust to new situations and handle them well. You might know this reaction as the fight-or-flight response. This response is just another name for the first stage of the stress response cycle. When you think about human evolution, having this built-in response makes sense. In the prehistoric ages, this was necessary so that humans could stay alive. Otherwise, they would have risked getting complacent and hurt by some wild animal.

But, because of the fight-or-flight response, their body was fit to run away from danger. Of course, society has evolved, and we don’t need to run from wild animals anymore. But that doesn’t mean stress doesn’t still serve a purpose. For example, it can still help you focus more during a test.

How Stress Affects You

How does stress prepare the body for these situations? When a stressor stimulates the nervous system, the body produces large quantities of cortisol and a few other hormones. This triggers a few changes at a physical level. Most notably, it increases blood pressure by increasing your heart rate. It also leads to heightened muscle preparedness, sweating, and general alertness. All these factors allow you to respond better to particular challenges.

So, what’s the catch? Why is stress so bad? Even though only the good parts were described so far, that’s not the whole story. In reality, stress is only suitable in small quantities. But, when someone feels overstressed, their mental and physical health diminishes. You might be sluggish or experience exhaustion. On the physical side, too much cortisol can lead to heart, digestive system, and even muscular issues.

For example, a 2018 review of a few studies found a link between work-related stress and an increased risk of coronary heart disease. Psychological problems are not something that can be overlooked either. Repeated stress can evolve into a mental health struggle. Acute stress is more common but can even develop into chronic stress. Depression, anxiety, and PTSD are just a few other issues caused by stress.

You can avoid all of these risks by understanding the stress response cycle. Whether you know about this cycle or not, it’s best to understand it. That way, you can learn what your body needs to cope healthily.

3 Stages of the Stress Response Cycle

Alarm, resistance, and exhaustion–let’s look at how each stage contributes to your worried mind.


1.      The Alarm Stage

The stress response cycle begins with the alarm stage. Then, it’s triggered by a stressor, which is usually a tense or dangerous situation. Next, the amygdala (involved in processing emotions and memories associated with fear) sends signals to the hypothalamus (the link between the endocrine and the nervous system). Then, the hypothalamus activates the sympathetic nervous system, releasing adrenaline into your bloodstream.

This is your body’s most visceral reaction to a threatening stimulus. These signals trigger changes, such as an increased breathing rhythm and rapid heartbeat. As a result, you’ll experience a rapid spike in your energy levels and increased alertness. This is why and how stress can keep you up at night.

These physical changes will boost your energy no matter how tired you are. This stage is what people know as the fight-or-flight response. It’s the same response that all animals have. But the human stress response cycle is a little more complex than animals. We have a couple more stages than they do.

2.      The Resistance Stage

The second stage of the stress response cycle is the resistance stage. This is when the body senses the danger or pressure has passed, so it presses the breaks. To be more exact, the parasympathetic system lessens the body’s stress response, but not completely. It still allows you to be alert so you can make sure that you are truly safe.

It’s also the stage where you can tell if you’ve regained balance. This stage will allow you to recover from the shock you’ve experienced. But that won’t be possible if your life is full of stressors. Because of that, your body will always be on high alert.

Still, this stage is not always timed perfectly. Sometimes, your body will stop releasing hormones before the danger has passed. In that case, the nervous system will need to re-release hormones. The bad part is that you’ll experience a rapid decrease in energy levels followed by another spike.

This is a shock, so you will likely become irritated or upset. You might even lose your concentration. Whether this cycle is timed wrong or doesn’t stop, the result is the same. It will lead to the final stage of the stress response cycle.

3.      The Exhaustion Stage

As the name suggests, the final stage of the stress response cycle, exhaustion, happens when your body is overloaded with stress. The exhaustion stage doesn’t always have to happen, as your body can recover before reaching this point. But if you’re dealing with chronic or unmanaged stress, you won’t be able to avoid it. Ideally, people would be able to prevent this stage altogether.

But the only way to do that is to give your body time to recover and stop dumping hormones in your bloodstream. That’s why taking breaks is so important if you have a demanding job, for example. If those breaks don’t happen, your body will go overdrive and release cortisol and adrenaline. Slowly, your body’s resources will be exhausted. There are only so many hormones your body can produce before running out.

At some point, you’ll be without adrenaline and experience a massive decrease in energy. But that’s not the only issue. When your body is overworked, its normal functions are affected. Remember that stress makes your heart beat faster and affects your breathing, muscles, digestive system, and more. All those systems will suffer when they are overworked. In time, you can develop chronic conditions like heart disease, diabetes, mental health issues, etc.

This is why it’s essential to manage your stress. If you are dealing with chronic stress, you must contact a therapist and work through your issues. You also need to identify your stressors and try to eliminate them. For example, if your stress is mainly caused by work, you might want to consider changing it.


Final Thoughts on Understanding the Three Stages of the Stress Response Cycle

Whether we like it or not, we’ll have to deal with some stress throughout our lives. But that doesn’t mean being stressed always is normal or beneficial. Small quantities can help you be alert and up for a challenging task. But when it gets out of hand, it can threaten your mental and physical health. And the three stages of the stress response cycle–alarm, resistance, and exhaustion–show precisely that.

The dangers of chronic stress are apparent when you look at the last stage, so beware of how you manage it. The three stages of the stress response cycle are alarm, resistance, and exhaustion. You’ll always have to deal with the first two when stressed. The alarm stage is when the stressor triggers your body, and your nervous system reacts by releasing hormones. The resistance stage is when your body decreases hormone levels so it can allow you to cool off.

Still, it keeps you somewhat alert if the danger hasn’t passed. Lastly, you have the exhaustion stage, which you should try to avoid. That stage happens when you are in a constant state of stress. You must manage your stress to ensure you don’t end up there. At the very least, try to find relaxing activities throughout the day. If your stress is chronic and unmanageable, you should consult a specialist.
