Stress is a common phenomenon in everyday life. It is in fact a normal physiological reaction of the body to difficult or dangerous situations, but it becomes problematic when it becomes chronic.
What are its mechanisms and what assets can limit its impact? Find out in this article.
Stress mechanisms
Stress is the nervous system's response to a situation perceived as a threat or challenge. When a person is exposed to a stressor, the brain triggers a chain reaction:
The hypothalamus releases stress hormones called corticotropins (CRH). These hormones stimulate the pituitary gland at the base of the brain to release adrenocorticotropic hormone (ACTH). ACTH reaches the adrenal glands, located above the kidneys, and stimulates the production of cortisol.
Cortisol has powerful effects on the body, increasing heart rate, blood pressure and blood sugar levels, while temporarily blocking non-essential functions such as digestion and reproduction. At the same time, the famous catecholamines (dopamine, adrenalin and noradrenalin) are secreted.
These physiological reactions are designed to prepare the body to react quickly, but are also temporary, so as not to affect the organism. The stress hormones cortisol and catecholamines then act in retrocontrol on the brain.
However, prolonged exposure to stress leads to excessive cortisol secretion, preventing recovery and the return to equilibrium, exhausting the body and adversely affecting health.
Effects of chronic stress on the body
Excessive stress can have many negative effects on the body.
Cardiovascular: it can increase the risk of cardiovascular diseases such as high blood pressure, stroke and heart attack.
Digestive: it can cause digestive disorders such as abdominal pain, bloating and diarrhoea.
Endocrine: chronic stress affects the production of hormones such as insulin, which can lead to health problems such as diabetes.
Immune: it can weaken the immune system, increasing the risk of viral and bacterial infections...
Muscles: stress can cause muscle tension and chronic pain.
Mental: anxiety, depression and sleep disorders...
In addition to implementing essential vital hygiene measures (healthy diet, regular exercise, oxygenation and breathing, etc.), certain natural active ingredients can help the body resist intense stress.
Stress and natural active ingredients
Rhodiola: Rhodiola is an adaptogenic plant native to the Arctic and mountainous regions of Asia and Europe, known for its anti-stress properties. It can help reduce fatigue, improve mood and promote resistance to stress.
Ashwagandha: Ashwagandha is another adaptogenic plant, native to India and often used in Ayurvedic medicine. Research shows that it can help reduce cortisol levels in the body. It improves physical and mental stamina, mood and reduces anxiety.

L-theanine: L-theanine is an amino acid naturally present in green tea. It has relaxing effects on the brain and can help reduce anxiety and promote concentration.
Magnesium: magnesium is an important mineral involved in many bodily functions, including stress regulation. Magnesium deficiency can increase reactivity to stress, so it's important to maintain adequate levels.
It is important to note that these natural active ingredients may be beneficial for some individuals, but their effects may vary. It is advisable to consult a health professional before using dietary supplements, especially if you have existing health problems or are taking medication.
