Situation 1: Excessive planning, constant news scrolling before bed, or anxious thoughts about the future.
Situation 2: Insufficient quality sleep (less than 7 hours) and ignoring the need for rest.
Emotion: Chronic anxiety and tension that prevent relaxation.
Emotion: Exhaustion and irritability.
Hormonal Reaction (Consequence)
The endocrine (hormonal) and nervous systems are deeply interconnected. Any element we focus our attention on, a stimulus, instantly provokes an emotional reaction. This reaction, in turn, transforms into a direct chemical signal for the endocrine organs.
As established, while we cannot directly control hormone production, we can certainly influence it through our emotional state and overall lifestyle.
Attention (Stimulus): This is an external or internal trigger the mind focuses on (e.g., seeing food ads, constant thoughts about deadlines, or lack of sleep).
Emotion (+Action): This is the internal psychological response to the stimulus (anxiety, boredom, seeking pleasure). The emotion may be accompanied by an action (e.g., stress eating). This emotion becomes a neurochemical signal for the body.
Hormonal Reaction: Endocrine organs (adrenal glands, pancreas, thyroid gland) respond to this signal by releasing specific hormones (Cortisol, Insulin, etc.), which then directly affect metabolism.
Next, we'll take a closer look at how this sequence works using examples of major hormones.
Let's examine the mechanism of this chain:
Insulin: The Regulator of Energy and Fat Storage
The influence of the psycho-emotional state on the endocrine system
The principle
“Attention–Emotion–Hormonal Reaction”
A persistently high insulin level sends a powerful signal to the body: "Store fat, don’t burn it." Furthermore, it increases appetite and induces those often uncontrollable sugar cravings.
Insulin is a hormone produced by the pancreas that helps cells absorb glucose (sugar) from the bloodstream, either using it for immediate energy or storing it.
When the diet frequently includes large amounts of refined carbohydrates, your cells can develop insulin resistance (becoming less responsive). To compensate, the pancreas is forced to produce even more insulin to overcome this cellular resistance.
You can effectively regulate insulin levels through:- Nutrition: Eliminate refined sugar and simple carbohydrates from your diet. Instead, incorporate fiber (greens, vegetables) and healthy fats (avocado, nuts) to slow down glucose absorption.
- Meal Timing (Intermittent Fasting): Give your body a necessary break. A 12–14 hour interval (e.g., fasting from 8:00 p.m. until 8–10 a.m.) lowers insulin levels. This allows the body to access and utilize its own fat stores. (More detail → The Science of Intermittent Fasting for Women.)
- Physical Activity: Engage in strength training and brisk walking after meals. This helps your muscles effectively utilize circulating glucose, thereby reducing the pancreas's demand for insulin.
Chronically elevated cortisol causes the body to store visceral fat (the most dangerous type of fat surrounding internal organs), creating a "strategic reserve" of energy for anticipated prolonged stress. Moreover, it also degrades sleep quality and increases appetite.
Cortisol is a hormone produced by the adrenal glands and forms a part of the "fight or flight" response. Its main purpose is to supply the body with energy (glucose) during a critical situation.
In the modern world, cortisol responds not only to physical danger but also to psychological triggers such as chronic sleep deprivation, looming deadlines, perfectionism, and constant worrying.
You can regulate cortisol levels by following these effective techniques:- Quality Sleep: Serves as the body’s primary regulator of cortisol. Aim for 7–9 hours nightly. The fat-burning hormone, Growth Hormone (GH), is chiefly produced during deep sleep, making it especially beneficial to rest before 11:00 p.m.
- Relaxation Techniques: Dedicate at least 10 minutes daily to meditation or diaphragmatic breathing (deep belly breathing). This practice immediately lowers cortisol levels and shifts the nervous system from "fight mode" to "recovery mode."
- Nutrition: Consume foods rich in magnesium (leafy greens, seeds) to help calm the nervous system and support adrenal gland function. Avoid caffeine in the second half of the day.
These hormones are closely linked to both the intake of essential micronutrients and the body’s overall stress burden.
Thyroid hormones (Thyroxine T4 and Triiodothyronine T3) act as the "thermostat" of your body. They control the rate at which every cell converts food into usable energy.
When their activity diminishes (a condition known hypothyroidism), the metabolism slows down, resulting in weight gain, swelling, chronic fatigue, and hair loss.
You can enhance thyroid function through: - Nutrients: Ensure adequate intake of iodine (seaweed, seafood, iodized salt), selenium (Brazil nuts), and zinc (pumpkin seeds, meat). These micronutrients are essential for thyroid hormone synthesis.
- Nutrition: Avoid inflammatory foods (trans fats, excess sugar). Chronic inflammation can inhibit the conversion of inactive of T4 to active T3.
- Stress Management: Cortisol and thyroid hormones are closely linked. Reducing stress levels (see the cortisol section) directly helps restore thyroid function.
Situation 1 (Snacking) The habit of "snacking" without physical hunger (e.g., while watching a movie).
Situation 2 (Stress Eating) Stress or tension that prompts an attempt to "calm" the nervous system.
Situation 1: Prolonged, chronic, and unmanaged stress.
Situation 2: Chronic deficiency of iodine, selenium, and zinc in the diet.
Emotion: Boredom, or a habit that has evolved into a search for pleasure.
Emotion: Anxiety or tension → Action: Eating for short-term relief.
Emotion 1: Chronic exhaustion, apathy.
Emotion2: Sluggishness, lethargy.
Hormonal Reaction (Consequence)
Carbohydrate consumption → Sharp spike in glucose → Insulin release → Fat accumulation.
Activation of the pleasure center → Sugar spike → Sustained increase in insulin and risk of insulin resistance.
Reaction 1: The brain relays an alarm signal → Chronic increase in cortisol → Accumulation of visceral fat and catabolism (breakdown) of muscle tissue.
Reaction 2: Disruption of circadian rhythms → Imbalance in cortisol production (may be elevated in the evening) → Poor sleep and an increased risk of weight gain.
Hormonal Reaction (Consequence)
Reaction 1: Elevated cortisol (the stress hormone) can inhibit the conversion of T₄ to active T₃ → slowing down metabolism.
Reaction 2: Lack of essential "building materials" → Decreased production of T₃ / T₄ → weight gain and swelling.
