Scientists Explain 8 Things That Happen To Your Body When You’re Overstressed


“Stress is an ignorant state. It believes that everything is an emergency. Nothing is that important.” – Natalie Goldberg.

Stress manifests when someone experiences excessive levels of emotional or mental pressure. This emotional or mental pressure creates distress – a harmful psychological state that can damage both mind and body.

It is not hyperbole to say that stress can kill you. This fact and the near-universal presence of stress in daily life does not bode well for individual and public health. Consider some of these alarming statistics:

– 77% of people regularly experience physical symptoms caused by stress.

– 73% of people regularly experience psychological symptoms caused by stress.

– 33% of people feel “they are living with extreme stress.”

– 48% of individuals report lying awake at night due to stress.

– 48% of people cite stress as harming their personal and professional life.

The human body consists of 78 organs total, divided into 13 “major” organ systems. Of all organs, five are vital: the brain, heart, kidneys, liver, and lungs. Why do we mention this? Because stress negatively affects them all, particularly the vital organs.

In this article, we discuss stress’ impact on ten major organ systems. We’ll also provide some practical ways of destressing the body and mind (including the organs, of course)!

This Is What Happens To Your Body When You Feel Overstressed

1. An Overstressed Cardiovascular System

The cardiovascular system consists of our heart and blood vessels and is a potentially life-threatening target for chronic high stress. Cardiovascular disease accounts for approximately 610,000 deaths every year in the United States – or 1 in every four fatalities. According to the Centers for Disease Control and Prevention (CDC), it is the leading cause of death for men and women.

Moreover,  research continues to link cardiovascular disease and stress. The presence of stress, particularly combined with other risky behaviors (e.g., smoking, alcohol abuse), is thought to increase one’s risk drastically to this disease.

2. Nervous System

The brain and spinal cord are “the central division “ of the nervous system. The autonomic nervous system (ANS) “has a direct role in physical response to stress); which is divided into the sympathetic nervous system (SNS) and parasympathetic nervous system (PNS).

Stress starts ends, and everything in between, within the brain. Stress initiates the “fight or flight” response. It releases stress hormones that spread throughout the body, causing “the heart to beat faster, respiration to increase, blood vessels in the arms to dilate,” in addition to other side effects.

In short, chronic stress is not suitable for the brain.

3. Respiratory System

The bronchi, larynx, lungs, nose, pharynx, and trachea form the respiratory system. The brain’s fight or flight response causes one to breathe harder, sometimes to the point that one experiences hyperventilation.

In fact, panic attacks, a sudden feeling of acute and disabling anxiety, are a common medical condition in those with chronic stress.

4. An Overstressed Musculoskeletal System

Our bones, joints, and muscles make up the musculoskeletal system. In fact, stress has a way of causing our body to tense up. In an acute state, this tension releases, and “that is that,” as they say. However, chronic stress “causes the muscles in the body to be in a more or less constant state of guardedness;” chronic painful conditions and musculoskeletal disorders can manifest in this state.

5. Reproductive System

Our reproductive system encompasses the gonads, accessory organs (e.g., prostate, uterus), Genitalia, mammary glands, and genital ducts (male).

For both men and women, the nervous system influences the reproductive system. In men, the ANS produces testosterone and activates the sympathetic nervous system to create arousal. Stress adversely affects women across various functions: menstruation, premenstrual syndrome (PMS), menopause, and sexual desire.

During times of stress, the brain releases cortisol. Over time, this may disrupt the normal function of anatomic reproductive components.


6. An Overstressed Endocrine System

The adrenals, hypothalamus, pancreas, parathyroid, pineal gland, pituitary gland, ovaries, testes, and thymus make up the endocrine system.

Once again, the brain initiates the release of stress hormones, cortisol, and epinephrine, via the hypothalamus. The adrenals, located near the kidneys, produce cortisol and epinephrine; this heightens the body’s stress awareness levels.

The liver produces glucose during the abovementioned process, which generally provides aid during fight or flight mode. However, this excess blood sugar could lead to Type 2 diabetes in vulnerable demographics, including the obese and some races (e.g., Native Americans).

Thus, managing stress is vital to maintaining an average blood sugar level. Besides that, you will potentially avoid diabetes in certain situations.

7. Integumentary System

This system includes the hair, nails, and skin. The integumentary system plays an essential role in maintaining the body’s equilibrium, “including protection, temperature regulation, sensory reception, biochemical synthesis, and (nutrient) absorption.”
