In today’s world, more and more people are struggling with chronic stress, anxiety, and emotional imbalance. These problems often become so normalized that we treat them as part of everyday life. Meanwhile, science increasingly emphasizes the close connection between mental health and lifestyle – especially diet, sleep, physical activity, and exposure to harmful substances. Below, we present key areas that significantly influence emotional resilience and psychological well-being.
1. The Impact of Diet on Mental Health
A highly processed diet rich in sugar, refined flour, trans fats, and additives not only negatively affects metabolism but also significantly influences the nervous system and brain. Studies show that poor-quality food increases inflammation and oxidative stress, disrupting neurotransmitter function and worsening mood. In contrast, a whole-food diet rich in healthy fats, protein, vitamins, and minerals supports emotional stability, stress resistance, and clarity of thinking.
2. Low-Carb Diet – Fuel for the Brain and Stable Mood
Diets low in carbohydrates (low-carb or ketogenic) may have particularly beneficial effects on mental health. By limiting sugar intake, we avoid sudden blood glucose spikes, which translates to more stable energy and emotions throughout the day. Ketones – produced during low-carb diets – provide an efficient and stable energy source for the brain. Additionally, this type of diet reduces inflammation, which is strongly linked to the development of depression and anxiety.
However, it’s important to remember that the body’s adaptation to a low-carb diet is individual – some people may experience temporary mood deterioration at the beginning, which usually subsides after the adaptation phase.
3. Nutrient Deficiencies and Mental Health
Even small deficiencies of key micronutrients can significantly affect mood, concentration, and stress coping abilities. Especially important are:
- B vitamins (B12, B6, folic acid): support neurotransmitter production; their deficiency is linked to depression and anxiety.
- Magnesium: called the “element of calm”; its lack increases irritability and emotional instability.
- Iron: even mild deficiency impairs brain function, affecting mood and cognitive performance.
- Zinc: supports neurogenesis and nervous system protection; its deficiency is associated with depression and anxiety disorders.
- Vitamin D: low levels are common in people with depression and reduce resilience to stress.
Nutritional deficiencies disrupt the production and function of neurotransmitters, increase oxidative stress, and hinder brain regeneration.
4. The Importance of Lithium – Even in Trace Amounts
Although rarely discussed, lithium – even in trace amounts found in natural water – may be key to emotional balance. Research shows that areas with higher lithium concentrations in drinking water have lower rates of depression, bipolar disorder, and suicide.
Lithium supports the regeneration of brain cells, stabilizes mood, increases BDNF (a brain growth factor), and protects against damage caused by chronic stress. Microdoses of lithium – occurring naturally in water and some supplements – may support mental health without the side effects seen in psychiatric doses.
5. Physical Activity and Mental Resilience
Regular physical activity is one of the best natural tools to improve mood and reduce stress. Exercise reduces cortisol levels (the stress hormone), increases serotonin and endorphin production, and supports neurogenesis – the creation of new brain cells.
Exercise also improves memory, concentration, and reaction speed. Over time, it leads to structural changes in the brain that protect against depression and enhance the ability to handle challenges. Importantly, the benefits apply to all types of movement – from walking to strength training. Regular movement also improves self-esteem and the sense of control over life.
6. Sleep – The Foundation of Emotional Balance
Sleep is a key pillar of mental health. Its deficiency – whether due to insomnia, poor quality sleep, or too short sleep duration – increases the risk of depression, anxiety, and emotional instability.
During sleep, the brain regenerates, neurotransmitters balance out, and the body reduces accumulated stress hormones. Lack of sleep disrupts this balance, increases cortisol levels, impairs concentration, memory, emotional control, and raises reactivity to daily problems. One sleepless night can significantly worsen mood and cognitive function. Chronic sleep deprivation has long-term consequences for the brain and mental health.
7. The Effect of Stimulants on Mental Health
Alcohol, drugs, and other psychoactive substances may initially provide the illusion of relief, but in the long term, they worsen mental health. They disrupt brain chemistry, increase the risk of depression and anxiety, impair sleep, and increase emotional instability. Additionally, addiction leads to a deterioration in social life, relationships, and lowers overall life quality.
Even cannabis, often considered “mild,” in many people increases anxiety, irritability, and emotional detachment, especially with regular use. While some substances (like psychedelics) are being studied for therapeutic use, unsupervised use may carry risks and often results in a worsening of mental state.
Summary
Mental health is closely linked to the condition of the body – especially the nervous system and brain, which need quality fuel, regeneration, and protection. A balanced diet, sleep, physical activity, and avoiding harmful substances are not just an “addition to therapy” – they are its foundation. In many cases, lifestyle changes alone significantly improve emotional resilience and stress coping abilities.
Even if you’re undergoing psychological therapy or taking medications – supporting your body through proper nutrition, supplementation, sleep hygiene, and daily movement can greatly enhance your healing and balance process.
