5 Deadly Effects Of Stress On The Body—It’s More Than Just A Mental Struggle

In This Article

Whether it’s rushing to work because you’re late for a meeting, scrambling to submit an assignment before the last hour of a deadline, or thinking about the bills you have to pay at the end of the month or the never-ending daily responsibilities that plague your life, you’re not alone.

Millions of people worldwide find themselves constantly overwhelmed by the fast-paced demands of modern life. The salient pressure to keep up with everything often leads to high stress and anxiety levels. While many have adapted to the hustle culture that sees rest as a reward rather than a form of basic self-care, it is important to recognize the effects of stress on the body.

As normal as it may seem, a constant state of stress can significantly affect our physical and mental health, ranging from increased heart rate and blood pressure to difficulty sleeping, poor concentration, feelings of hopelessness, burnout, and many other critical issues.

Hence, it’s important to know what stress truly is and the effects of stress on the body.

What Is Stress?

The World Health Organization (WHO) defines stress as a state of worry or mental tension arising from a difficult situation. When any situation demands something to which we are not naturally accustomed, we are bound to feel stressed. Stress often appears due to pressure to respond to our daily challenges and threats.

We have all experienced one form of stress or another. Whether it is stress related to a crisis in our relationships, finances, health, academics, or personal lives, everyone experiences stress to some degree.

The way we respond to stress makes a big difference in our overall well-being. When stress occurs in small amounts, it can be good—for example, when public speaking or in the final lap of a marathon, you need a fair amount of adrenaline to push through. When it’s persistent, it can have negative effects on your well-being.

Without further ado, let’s look at five effects of stress on the body.

Heart Problems

Have you ever been stuck in traffic, anxiously unable to do anything as the clock ticks away, rushing to complete an important task, or having to run away from danger?

Do you ever notice one common thing that happens to your body in those moments? Your heart starts to beat faster and more forcefully. This is your body’s own way of ensuring that your brain or muscles receive the necessary nutrients to overcome the perceived threat.

So, in a scenario where you have to run from danger, your heart starts to pump blood faster and redirects the blood to your legs so you can run faster. While this response can be life-saving, over a long period, the effects of stress on the body can take a toll on your heart.

When your body is continually under stress, it puts a lot of pressure on your heart, and over time, this high blood pressure can strain the heart, making it less efficient and potentially leading to heart diseases and problems such as:

  • Hypertension: Constant exposure to stress can cause the vessels in your heart pumping blood to remain constricted, which increases overall blood pressure. This reduces the efficiency of your heart and can cause heart disease.
  • Heart failure: The constant strain on the heart from constant stress weakens the muscles of the heart, leading to heart failure—a condition where the heart can’t pump enough blood to meet the body’s demands.
  • Stroke: Sudden changes in your blood vessels due to stress can damage them, making them more likely to rupture. When this happens, the blood supply to your brain is interrupted or reduced, leading to a stroke.

Weakened Immune System


Every day, we’re exposed to bacteria, viruses, and other harmful disease-causing organisms from the air we breathe, the water we drink, the food we eat, and our environment. Our immune system is the guardian that protects us from these invaders; however, there’s a limit to how much it can protect us.

Whenever there’s a potential threat, the immune system goes into action by producing antibodies to eliminate the invaders. This response is what keeps us safe and healthy. However, a long-term effect of stress on the body is the compromise of the immune system, leaving us more susceptible to illness. This compromise can be in the form of:

  • Decreased production of immune cells: Chronic stress can reduce the production of the cells that identify and destroy foreign bodies in your body.
  • Increased susceptibility to infections: Weakened immune function means you are more susceptible to infections such as the common cold, flu, or even more severe illnesses.
  • Slow healing: When the immune system is compromised, the body’s ability to heal wounds and recover from illnesses or injuries can be impaired.

Digestion Problems

The digestive system is responsible for breaking down the food you eat, absorbing the necessary nutrients, and eliminating waste. It works efficiently under normal conditions, but when the body is under stress, it can disrupt how your body digests food, causing harm to your physical health.

Earlier, you learned how, during a threat, the body prioritizes the brain and muscles by directing the necessary nutrients from other body parts. The effects of stress on the body also include reduced blood and oxygen flow to the digestive system, causing digestive problems such as:

  • Food sensitivity: Stress can make you sensitive to certain foods you like and enjoy eating. The foods can appear irritable to you and even cause worse symptoms like stomach pain and bloating when you eat them.
  • Increased stomach acid: Stress can stimulate the production of stomach acid. While this is a helpful response in short bursts to help break down food, chronic stress can lead to excessive acid production, potentially causing heartburn or worse conditions like gastroesophageal reflux disease (GERD).

Anxiety And Depression

One of the most overlooked effects of stress on the body is the anxiety and depression that come with it. These conditions often result from stress, which contributes to their development.

Imagine if every day you had a deadline to meet or had to rush to a meeting, constantly living your life on the edge of your seat, always thinking about the next deadline over and over again.

When stress becomes constant or overwhelming, it can trigger anxiety, restlessness, sleep disorders, and depression. Stress can heighten these emotions, leading to never-ending feelings of unease and tension. These feelings can escalate into sudden panic attacks anytime you think of a deadline or undergo any form of stress. Examples of the effects of stress on the body leading to anxiety and depression are:

  • Bad mood: Chronic stress can significantly affect your mood. You’re more likely to feel sad, hopeless, and exhausted when you’re always under stress.
  • Negative thought patterns: Stress can encourage negative thought patterns, which breed depression. These patterns involve persistent worrying and self-doubt.

Sleep Deprivation


What’s the hardest thing to do when you’re stressed? It’s probably sleep. Sleep is your body’s natural way to reset and refresh. Sleep is important for your physical and mental health. It allows our body to rest and repair itself. When we don’t get enough sleep, it’s always obvious on our faces, and our bodies feel different.

When you’re stressed, your mind is racing with worries and thoughts, making it difficult to relax and fall asleep. Even when you do manage to fall asleep, your sleep may be short and restless, leaving you feeling tired the next day. The lack of quality sleep further worsens the effects of stress on the body, leading to a vicious cycle that can be hard to break.

This cycle of stress and sleep disturbances can have a significant impact on your overall well-being. Not only does it affect your physical health, but it also affects your mental and emotional state. The lack of restorative sleep makes you irritable, moody, and unable to concentrate during the day. It becomes harder to cope with daily activities, and even small challenges can feel overwhelming.

Sleep is essential for our physical and mental health. It allows our bodies and minds to rest and repair themselves. When we don’t get enough sleep, we are more likely to experience several health problems, like:

  • Fatigue: Lack of sleep from stress can cause you to feel tired and sluggish during the day, unable to perform even the most mundane tasks.
  • Difficulty concentrating: Sleep deprivation can make it difficult to focus and pay attention, putting you at risk for accidents or mistakes.
  • Mood swings: When you fail to get enough sleep, you may become easily frustrated and snapping at others for minor reasons. It can make you easily irritable and moody.


In a world that constantly demands more, stress has become a routine in the lives of millions, affecting both their physical and mental well-being. Stress is not merely an inconvenience; it’s a constant force that can throw off the delicate balance of our bodies and minds. As we’ve explored, stress can manifest in various forms, from heart problems and weakened immune systems to indigestion, anxiety, and sleepless nights.

Understanding the deep effects of stress on the body and mind is the first step toward reclaiming our health and peace of mind. Recognizing that stress is a part of life but doesn’t have to be a steady companion is very important. We have the power to control and reduce the effects of stress on the body.

Remember that rest is not a reward but a fundamental form of self-care. By acknowledging the toll stress takes on our lives and taking proactive steps to address it, we can break the cycle and live healthier, more balanced lives.
