Stress is a natural and physiological reaction of the body that allows us to flee or face the situation we are in.
If stress is controlled, lasts for a short period, and doesn't cause unpleasant physical sensations, it's considered a motivator and performance accelerator. A good dose of stress can help you escape an attacker, study more effectively before an important exam, or even deliver a public speech that's even better than in rehearsals.
However, if stress is chronic and too intense, it can decrease performance and have serious effects on mental and physical health.
When exposed to stress, the body generates an adaptive reaction consisting of three stages: the alarm phase, the resistance phase, and the exhaustion phase.
The different phases of stress

As with sleep, stress breaks down into these three distinct phases:
- The alarm phase: the body prepares for fight or flight, and the first symptoms of stress begin to appear. To defend itself, the body produces cortisol (a stress hormone) and adrenaline to increase energy levels, heart rate, blood pressure, and body temperature. Alertness, thinking, and the senses (sight, smell, hearing, etc.) are thus greatly heightened during this phase.
- The resistance phase: if stress persists, the body enters the resistance phase. The body tries to find a new balance by secreting more cortisol and producing significant amounts of neurotransmitters such as dopamine (linked to motivation) and serotonin (linked to well-being).
- The exhaustion phase: if stress is prolonged or intensifies, the body depletes its resources (physical, emotional, and mental) and enters the exhaustion phase. The main signs of this phase are chronic fatigue, irritability, high anxiety, and a weakened immune system.
The different symptoms of stress

Each individual reacts differently to stress, resulting in highly varied reactions. Some experience physical symptoms, while others suffer from mood swings or a loss of self-confidence.
Stress-related symptoms can be physical, psychological, or emotional. The most common are fatigue, irritability, trembling, crying, cognitive difficulties (concentration, attention, learning, etc.), various pains (stomach, head, etc.), skin manifestations (eczema, hives), hair loss, heart palpitations, eating disorders, sleep disorders , or even a depressive or nervous state.
Stress-related symptoms can occur in many situations (at work, at school, during pregnancy, etc.) and can have various causes such as traffic pressure, bad news, work overload, an important exam, relationship difficulties, financial problems, or a health problem.
The effects of stress on the body

The effects of stress on the body can be more significant than we realize, especially since we often experience stress without being fully aware of it. Yet, our bodies send us various warning signals that are essential to recognize and interpret in a timely manner. Discover below the main impacts of stress on health and why it is crucial to take them into account.
1. A weakened immune system
When we are subjected to prolonged stress , the body secretes an excess of certain hormones (notably cortisol). In the long term, this excessive production disrupts the normal functioning of the immune system.
- As a result , natural defenses are weakened, making the body more vulnerable to infections and common illnesses (colds, flu, etc.).
- Why pay attention : A less efficient immune system can lead to chronic fatigue, slow the healing of injuries and increase the likelihood of developing more serious illnesses.
2. Muscle and joint pain
Stress often leads to increased muscle tension , particularly affecting the back, neck, shoulders, and legs.
- As a result , diffuse pains appear, sometimes difficult to relieve, because their origin is not purely organic but linked to a prolonged state of tension.
- Why pay attention to it : In the long term, these pains can lead to inadequate posture, worsen certain pathologies (lower back pain, neck pain, etc.) and significantly reduce quality of life.
3. Headaches and neurological disorders
In addition to muscle pain, stress can manifest itself through recurring headaches : tension headaches or migraines, in particular.
- Associated symptoms : Mood swings, difficulty concentrating, or temporary memory loss are sometimes observed.
- Why pay attention : Chronic pain and cognitive disorders (irritability, memory lapses) can negatively influence professional and personal life, creating a vicious cycle of additional stress.
4. Digestive problems
The digestive system is particularly sensitive to hormonal and nervous system variations caused by stress.
- Common side effects : Stomach aches, gastroesophageal reflux, nausea or diarrhea.
- Irritable bowel syndrome (IBS) : Stress can aggravate or trigger this syndrome, characterized by bloating, diffuse abdominal pain and transit disorders (constipation and/or diarrhea).
- Why pay attention : Digestive problems that develop over the long term can lead to poor absorption of nutrients and disrupt the overall balance of the body.
5. Cardiovascular risks
Chronic stress puts significant pressure on the cardiovascular system , increasing heart rate and blood pressure.
- Consequences : High blood pressure, coronary artery disease and increased risk of myocardial infarction or stroke.
- Aggravating factors : People already suffering from coronary artery disease are even more exposed, as are those with risk factors (smoking, overweight, sedentary lifestyle, etc.).
- Why pay attention : Heart problems can occur suddenly and have serious long-term health consequences.
Stress affects various systems in our body: immune, muscular, neurological, digestive, and cardiovascular. It is therefore crucial to quickly identify warning signs (fatigue, pain, mood swings, or digestive issues) in order to implement stress management strategies and best protect your health.
Tips for reducing stress
Fortunately, there are effective solutions to reduce stress and prevent its undesirable effects.
Here are 5 simple tips to apply in everyday life:
- Playing sports: Sport is a true stress reliever; it allows the brain to release a series of calming hormones and neurotransmitters that help to better manage stress (endorphins, dopamine, and serotonin). Engaging in at least 30 minutes of physical activity daily thus provides a feeling of well-being and promotes a state of relaxation.
- Practice meditation: Meditation is an activity that helps alleviate stress and pain, better manage emotions, improve mood, and promote relaxation. Through breathing exercises, meditation helps free the mind from thoughts of the past and worries about the future, allowing you to focus solely on the present moment.
- Developing your creativity: Engaging in an artistic activity (music, writing, drawing, painting, dancing, etc.) is an effective way to relax and reduce stress. Adult coloring books, in particular, are useful for improving concentration and calming the mind.
- Laughter and socializing: laughter can evoke positive emotions in stressful situations, helping to overcome stress more easily. Furthermore, spending time and talking with others about different aspects of life can be reassuring, comforting, and improve mood.
- Using anti-stress plants: many plants have anti-stress properties that are effective in combating anxiety, nervousness, and anguish. They can be consumed in the form of infusions, tablets, capsules, or even gummies.
A course of these gummies helps protect the nervous system against stress and anxiety, thus promoting relaxation and well-being.
Increasingly popular in France,CBD is a molecule derived from the hemp plant, renowned for its relaxing and pain-relieving effects. Unlike THC, it does not produce psychoactive effects and is not addictive. Consuming CBD can therefore help combat stress and relieve stress-related pain.
They can be consumed at any time of day, during stressful situations or periods of overwork. Being natural, they do not cause side effects or addiction, and pose no health risks.
It is obviously recommended to consult a doctor if you suffer from chronic stress or severe anxiety disorders that impair your quality of life, in order to find appropriate medical treatment.
