Lactose intolerance is one of the most common causes of discomfort after consuming milk in adults. It is related to the function of the enzyme lactase, which is responsible for breaking down lactose in the intestine. If there is not enough lactase, symptoms such as bloating, gas, or diarrhea may occur. This is not a […]
In spring, the body often experiences fatigue, lack of energy, and a slight “drop” in immunity. That’s why the question what to eat in spring becomes especially relevant. The reason is simple: winter depletes reserves, and the diet was not very diverse. That’s why spring is not about diets, but about gentle recovery. More fresh […]
In spring, the skin often behaves strangely: it’s as if winter is over, but it hasn’t yet adapted to the warmth. Spring skin care is especially important, as dryness, sensitivity, sometimes breakouts, or uneven texture appear. The reason is simple — sudden temperature changes, more sun, and a protective barrier exhausted after winter. Good news: […]
Immunity in spring works differently: the risk of colds does not disappear and may even increase. Temperature fluctuations, changes in humidity, residual vitamin D deficiency after winter, and circadian rhythm shifts create conditions in which the body temporarily becomes more vulnerable. In most cases, this is not “weak immunity” but normal adaptation. During the spring […]
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 […]
