What is cortisol and how the body influences us
What is cortisol? It is a hormone produced by the adrenal glands, which are located above the kidneys. It is often called the "stress hormone" because it is released in larger quantities during stressful situations. For our state of physical and mental health, it is important to keep the cortisol at a low level.
In this article, we will talk about what cortisol is more precisely, how the body influences us, how we can discover if its level is optimal in the body and how we can balance it to enjoy a healthier life.
What is the role of cortisol in the body
Cortisol plays an important role in many functions of the body, including:
Adjusting the response to stress
Cortisol helps the body to manage stress by increasing the available energy level and temporarily suppressing non-essential functions.
Cortisol is a key element of the "struggle or run" response of the body, a survival mechanism that activates in stressful situations. When you face physical or mental stress, the brain sends signals to the adrenal glands to release cortisol.
Cortisol stimulates the release of glucose (sugar) from liver reserves, thus ensuring a rapid source of energy for muscles and brain. In situations of acute stress, cortisol temporarily reduces the activity of systems that are not essential for immediate survival, such as digestion, reproduction and growth. This allows the body to focus the resources on the response to stress.
Metabolism of carbohydrates, proteins and fats
Cortisol helps control how the body uses carbohydrates, proteins and fats. It stimulates the liver to produce glucose from proteins and fats, an essential process for maintaining blood sugar or prolonged stress.
At the same time, it promotes lipolysis, decomposition of fats stored in free fatty acids that can be used as energy source. In periods of stress or increased energy needs, cortisol breaks down the proteins from muscle into amino acids, which can be converted into glucose or used in other metabolic processes.
Inflammation control
Cortisol has anti -inflammatory effects and helps regulate the immune response. It decreases the production of prostaglandins and cytokines, substances that contribute to inflammation and pain. It also reduces the activity of white blood cells and other components of the immune system, preventing exaggerated inflammatory responses that could damage healthy tissues.
Regulation of blood pressure
Contributes to maintaining blood pressure within normal limits. Cortisol causes blood vessels to respond more effectively to adrenaline and noradrenaline, hormones that narrow blood vessels and increase blood pressure. Moreover, it influences the kidneys to retain sodium and water, which contributes to increased blood volume and implicitly blood pressure.
Sleep adjustment
The cortisol helps control the sleep-ware cycle, having higher levels in the morning and low in the evening, before sleep. Because cortisol begins to grow in the last hours of the night, reaching a peak early in the morning, helps to wake up and prepare the body for daily activities, offering energy and vigilance.
During the day, the level of cortisol gradually decreases, reaching minimum in the evening, preparing the body for sleep. The disorders of this cycle can lead to sleep disorders and other health problems.
How can we balance our cortisol level
The natural regulation of the level of cortisol in the body can be achieved by lifestyle changes and by adopting healthy habits.
If the balance of cortisol is disturbed, it can affect not only waking and sleep, but also other aspects of health, such as immunity, metabolism and mental health (it can lead to anxiety, stress, insomnia).
Here are some effective techniques by which you can lower your body level in the body:
- Stress reduction: Practices such as meditation, yoga, deep breathing and progressive muscle relaxation can reduce cortisol levels by calming the nervous system.
- Quality sleep: Maintaining a constant sleep program, sleeping and waking up at the same hours daily, helps stabilize the levels of cortisol. Ask you to sleep in a dark, quiet and comfortable environment. Avoid using electronic devices before bedtime at least 30 minutes, because the blue light can disrupt the circadian rhythm.
- Regular physical exercises: Regular physical activity, of moderate intensity (such as walking, swimming or cycling), can reduce cortisol levels and improve mood. Regot as intense and excessive exercises can increase cortisol levels, so it is important to find a balance.
- Balanced diet: Maintaining a regular food program, with balanced meals, helps to stabilize the level of cortisol. Avoid jumping over meals, as this can lead to fluctuations in cortisol. Fruits and vegetables rich in antioxidants can help reduce oxidative stress and, implicitly, cortisol. Consumption of fat, nuts and seeds, which are rich in omega-3 fatty acids, can help reduce inflammation and cortisol.
- Caffeine limitation: Excessive consumption of caffeine can increase cortisol, especially when consumed in high doses or at times of stress. Reducing coffee consumption and other caffeine drinks can help maintain cortisol levels within normal limits.
- Adequate hydration: Dehydration can increase cortisol levels, so it is important to remain well hydrated throughout the day.
- Socialization: The time spent with family, friends and pets can reduce stress and cortisol. Talk about your problems with someone of trust. Emotional support can have a positive impact on cortisol levels.
- Natural supplements: adaptogenic plants such as Ashwagandha have been studied for the effects of reducing cortisol and improving the response to the stress. Another adaptogen is Rhodiola Rosea, which can help reduce cortisol and combat mental fatigue.
Remember! There is a specific blood analysis to measure the level of cortisol in the body. This is called the serum cortisol test. Blood is usually collected in the early morning, because cortisol levels vary during the day and are the highest in the morning, shortly after waking up. The blood sample is then analyzed in the laboratory to determine the concentration of serum cortisol.
Studies on cortisol
There are numerous studies that explore the role of cortisol in health and the conditions associated with its high levels. They cover a wide range of topics, including stress response, metabolism effects, impact on mental health and long -term influence on chronic diseases. Here are some examples of notable studies and discoveries:
Study "Stress, Cortisol, and the Risk of Alzheimer Disease: An Integrative Review" (2014)
Reviewed the literature on the connection between cortisol and Alzheimer's disease. It has been found that high chronic levels of cortisol are associated with cognitive damage and can contribute to the development of Alzheimer's disease, emphasizing the importance of stress management to prevent neurodegenerative diseases.
Study "Cortisol and Metabolic Syndrome: A Systematic Review and Meta-Analysis of Cross-Sectional Studies" (2016)
Meta-analysis has demonstrated an association between high levels of cortisol and metabolic syndrome, including abdominal obesity, hypertension, dyslipidemia and insulin resistance. High chronic cortisol is an important risk factor for these conditions.
Study "Elevated Cortisol Levels in depressive illness: A Meta-Analysis" (2000)
Has identified a consistent association between high levels of cortisol and depression. The study suggests that the hyperactivity of the HPA axis (hypothalamo-hypophizo-adrenal) plays an essential role in the physiopathology of depression.
Study "Chronic stress and immunity: The influence of relations, social support, and cortisol on immune function" (2011)
This study examined the effects of chronic stress and cortisol on immune function. It has been found that high levels of cortisol can suppress the immune response, increasing vulnerability to infections and other diseases. The study also highlighted the role of social relations and social support in moderating these negative effects.
Study "The Impact of Cortisol on Sleep: Insights from a Systematic Review" (2012)
This systematic review has shown that a cortisol -disturbed circadian cycle can lead to sleep problems, such as insomnia or poor sleep quality. The high levels of cortisol at night are associated with difficulties of falling asleep and awakening.
Study "The Effects of Physical Exercise on Cortisol Levels: A Review of Literature" (2015)
Analyzed the impact of different types of exercise on cortisol levels. It has been found that moderate intensity exercises can reduce cortisol levels, while intense exercises can increase them temporarily, but can lead to a general long-term decrease.
Study "Early Life Stress, Cortisol, and Psychopathology in Children" (2013)
It has struggled the connection between childhood stress, cortisol levels and developing psychopathological disorders. An association was observed between exposure to childhood stress, HPA axis dysfunction and increased risk of developing anxiety and depression in adolescence and adulthood.
