Spring sleep is often disrupted: it becomes harder to fall asleep, waking times shift, and in the morning the feeling of rest is gone. Sometimes this appears as mild spring insomnia or poor sleep in spring, when even a sufficient night’s sleep does not restore energy. It seems like there should be more light and […]
Constant fatigue, sleepiness, and feeling like you have “no energy” even in April — familiar situation? Often this is attributed to spring, but one of the causes may be vitamin D deficiency. After a long winter, its levels drop, there are still not enough sunny days, and the symptoms can easily be confused with ordinary […]
Despite the end of the winter season, spring colds remain a common occurrence. In spring, many people continue to experience acute respiratory infections. This is associated with several factors: depletion of the immune system after the winter period, seasonal changes in circadian rhythms, temperature fluctuations, and increased stress on the body’s adaptive mechanisms. In spring, […]
In spring, many people experience a phenomenon known as spring sleepiness — an increased need for sleep, decreased concentration, and fluctuations in productivity even with sufficient night rest. That is why many ask: why do we feel sleepy in spring even after a full night’s sleep? This phenomenon is associated with the adaptation of circadian […]
At the beginning of spring, there is an increased demand for the so-called spring detox and “cleansing” programs. However, from the perspective of evidence-based medicine, the body does not require an emergency detox. The liver, kidneys, intestines, and lungs work continuously, providing natural detoxification regardless of the season. Aggressive diets, fasting, and laxative regimens can […]
Seasonal Micronutrient Deficiency at the end of winter often manifests as fatigue, reduced immune protection, and decreased concentration. The most vulnerable are stores of vitamin D, iron, magnesium, B vitamins, and omega-3 fatty acids. Rational correction of such a deficiency requires laboratory assessment and an individualized approach to diet and supplements. Most Common Deficiencies During […]
Winter skin care is key to maintaining its health and barrier function during the cold season. Frost, wind, and dry air can deplete the skin, so proper prevention and daily care help avoid dryness, flaking, and redness. How cold and wind affect the skin Lipid barrier disruption and dryness The skin is not just a […]
Seasonal adaptation of the body is a period when the body gradually exits energy-saving mode but is not yet ready for springtime activity. At the seasonal boundary, many people experience fluctuations in well-being: mood swings, fatigue, decreased concentration, or increased sensitivity to stress. In most cases, this is related to natural adaptive processes rather than […]
Short Summary Everyday habits are rarely perceived as risk factors. They seem too minor to matter: an uncomfortable posture, skipping meals, lack of movement, constant tension. However, these very factors have a cumulative effect and over time can contribute to chronic pain — discomfort, fatigue, sleep disturbances, and reduced work capacity. Symptoms do not appear […]
Brief Summary Dehydration is not always accompanied by a feeling of thirst. The body can adapt to fluid deficiency for a long time, sending indirect signals: fatigue, headache, decreased concentration, dry skin, and mucous membranes. For this reason, mild or moderate dehydration often goes unnoticed and is perceived as “overfatigue” or a consequence of stress. […]
The liver is the body’s main “filter,” but it also has clear physiological limits. Against the background of stress, urbanization, and diets high in sugar and ultra-processed foods, interest in “detox programs” and hepatoprotectors is growing. This article examines how liver detoxification actually works, the role of diet and lifestyle, and where nutraceuticals may have […]
The skin microbiome consists of thousands of microorganisms that live on our skin and help protect against pathogens, regulate inflammation, and even influence barrier functions. Temperature, humidity, and sunlight change with the seasons—and the microbiome changes as well. In this article, we explore how different seasons affect the skin microflora and what role skincare and […]
