What are the effects of stress on the body?

les effets du stress sur le corps

Stress is a natural reaction of the body to a situation perceived as threatening or difficult to manage. 

Although a certain level of stress can be beneficial and motivate us to succeed, chronic stress can have many harmful effects on our body. But then, what are the effects of stress on the body

I. Understanding stress hormones and their effects

Stress hormones are chemical substances produced by the body in response to a situation perceived as threatening or difficult to manage. 


Stress hormones are ACTH (adrenocorticotropic hormone), cortisol, adrenaline, oxytocin and vasopressin. 

Levels of these hormones increase when the body is under stress to prepare the body to respond. 


Cortisolis considered the most important stress hormone because it has the most impact on the body's physical and mental functioning in response to stress. 

Adrenaline is also important in preparing the body to respond quickly to a stressful situation. 

Oxytocin and vasopressin are also involved in the body's response to stress, particularly in the regulation of the nervous and endocrine systems. 


In short, stress hormones play a major role in the body's natural response to a stressful situation.

1. The role of cortisol

Cortisol is an essential hormone produced by the adrenal glands. It is a steroid hormone that plays a crucial role in regulating many functions in the body.

Cortisol is synthesized from cholesterol in the fasciculated zone of the cortex of the adrenal gland. It is regulated by the hypothalamic-pituitary system.


When the body is under stress, the hypothalamus releases Corticotropin-releasing hormone (CRH), which stimulates the pituitary gland to secrete adrenocorticotropic hormone, or ACTH. ACTH in turn stimulates the adrenal glands to produce and release cortisol into the bloodstream.


Cortisol plays a crucial role in many functions in the body.


It intervenes in the carbohydrate metabolism, by increasing blood sugar to provide energy to the muscles when needed.


It also acts on fat metabolism, promoting the distribution of fats in the body.


Additionally, cortisol regulates blood pressure and plays a role in the immune response, reducing inflammation.


Finally, cortisol is often associated with the stress response.

In times of stress, cortisol levels rise to prepare the body to respond. It helps mobilize the energy needed to cope with a stressful situation.

However, an imbalance in cortisol levels can have negative consequences on health, including increasing the risk of mood disorders, anxiety and insomnia.


Long-term cortisol leads to an increase in blood pressure, which can have consequences for our cardiovascular health.

Additionally, it inhibits the production of new bone cells, which can lead to loss of bone density and increase the risk of fractures.


Adequate balance in cortisol levels is essential for maintaining good health and well-being.

2. The influence of adrenaline

Adrenaline, also called epinephrine, is a hormone and neurotransmitter that plays a crucial role in stress responses.

It is released by the adrenal glands in response to intense emotions like fear, anger and stress.

When released, adrenaline causes a series of physiological reactions in the body, which help prepare the body to respond to potentially dangerous situations.


Adrenaline stimulates the cardiovascular system, increasing heart rate and blood pressure.

It also dilates the bronchi, which allows an increase in air flow into the lungs.

In addition, it mobilizes energy reserves by increasing the concentration of glucose in the blood, which provides additional energy to the muscles and brain.

It can also cause sensations such as increased heart rate, palpitations, sweating, and a feeling of increased alertness.


Adrenaline is often associated with the "fight or flight" response, which is a physical and mental preparedness reaction to imminent threat or danger.

This hormone helps the body prepare to respond quickly and effectively in stressful or potentially dangerous situations.


In addition, adrenaline can have consequences on our behavior and our mood.

Some research has shown that adrenaline can increase aggression, violence, and hyperactivity in some people.

This may explain why people may become more impulsive, more agitated, or more irascible under the influence of adrenaline.


A prolonged high heart rate can damage the heart muscle and increase the risk of heart disease.

Additionally, the increase in blood pressure associated with adrenaline can overload blood vessels, leading to a deterioration in their functioning.


It is therefore important to maintain a healthy balance in hormonal levels.


3. The involvement of oxytocin and vasopressin

Oxytocin plays an important role in stress management by promoting the reduction in the release of cortisol, the stress hormone, by the pituitary gland. 


In addition, it exerts an anxiolytic effect by reducing the activity of the amygdala, a brain structure involved in the emotional response. 


On the other hand, vasopressin seems to have a stimulating role in the stress response, by increasing the release of ACTH, a hormone stimulating the production of cortisol, and by promoting the response to social stress. 


These two hormones, although related, appear to play opposing roles in regulating the stress response.



II. Understanding the effects of stress on the body

1. How stress affects the immune system

Chronic stress can weaken our immune system, making our bodies more vulnerable to illness and infection. 


When we are stressed, our body produces fewer white blood cells, the cells responsible for our body's defense.


This decrease in white blood cells can make it more difficult to fight bacterial and viral infections. 

Additionally, a weakened immune system can also promote the development of autoimmune diseases, in which the body attacks its own cells.


2. The effects of stress on the digestive system

Stress can have a significant impact on our digestive system


When we are stressed, our body diverts blood from the digestive organs to the muscles, which slows down the digestion process. 


This can lead to problems such as abdominal pain, bloating and transit problems.


Additionally, stress can also increase stomach acid production, which can lead to problems such as stomach ulcers or acid reflux.


3. The consequences on the skin

Stress can also have negative effects on our skin.


When we are stressed, our bodies release inflammatory chemicals that can cause skin problems such as:

  • acne
  • eczema
  • psoriasis
  • dry and itchy skin
  • cellular aging
  • teint terne

Additionally, stress can also aggravate already existing skin problems, such as redness, itching, or hives.

4. The overall consequences on the body


Chronic stress can cause a series of consequences on the human body, affecting various bodily systems and functions. It can disrupt hormonal balance, increase blood pressure and cause sleep disturbances.



5. The effect on muscles


Stress can cause muscle tension, pain and spasms. Tight muscles can lead to headaches, neck and back pain, and even long-term musculoskeletal disorders.



6. The general impact on the body


Stress can also affect the cardiovascular system, increasing the risk of heart disease. It can cause palpitations, increased heart rate and high blood pressure.



7. Effects and Anxiety


Stress-related anxiety can lead to mood swings, irritability, and panic attacks. It can also affect concentration and memory.



8. Specific effects in women


In women, stress can disrupt the menstrual cycle, cause period pain, and worsen symptoms of premenstrual syndrome (PMS). It can also affect fertility.



9. What pain is caused?


Chronic stress can also lead to metabolic disorders, such as unintentional weight gain or weight loss, as well as appetite disorders.



10. What are the symptoms?


Symptoms of stress can vary from person to person, but they often include headaches, trouble sleeping, muscle pain, digestive problems, irritability and fatigue.


III. Solutions to combat the effects of stress on the body

There are different methods to combat stress and the effects of stress on the body.

1. Practice deep breathing

Deep breathing can help reduce stress by activating the parasympathetic nervous system, which is responsible for relaxation.


There are several breathing techniques that can help reduce stress and anxiety. Here are some of them:

  • Mindful breathing: This technique involves focusing on your breathing and taking deep, intentional breaths to calm the mind and body.

  • Diaphragmatic Breathing: This technique involves inhaling deeply using the diaphragm, which can help activate the body's relaxation response.

  • 4-7-8 Breathing: This technique involves inhaling for a count of 4, holding the breath for a count of 7, then exhaling for a count of 8. It can help calm the nervous system and reduce stress.

  • Alternate Nostril Breathing: This technique is a yogic breathing exercise that involves breathing alternately through one nostril at a time, which can help balance the body and calm the mind.

2. Exercise regularly

Regular exercise is beneficial for reducing stress. It helps release endorphins, brain chemicals that act as natural painkillers and improve mood.

3. Practice meditation

Meditation is a technique that can help calm the mind and reduce stress. There are different kinds of meditations, voices, music, binaural sounds, or even simply going for a quiet walk in nature and sitting against a tree.

4. Promote a healthy lifestyle

Eating a balanced, healthy diet, practicing good sleep hygiene, and avoiding stimulants such as caffeine and alcohol can also help reduce stress.

5. Find relaxing activities

Making time for activities that provide pleasure and relaxation, such as reading, listening to music, pursuing a hobby, or spending time in nature, can help reduce stress.

6. Seek social support

Talking about concerns and stress with friends, family or a professional can help share the emotional burden and find solutions or advice.



It's important to find the methods that work best for you, because everyone has their own unique stress management strategies. Don’t be afraid to explore different approaches and ask for help if needed.
