Sleep occupies a central place in human life when viewed through the lens of regulation and homeokinesis . Rather than being a passive interruption between periods of wakefulness, sleep represents a distinct and indispensable phase in the continuous process through which a human being maintains integrity, adapts to changing conditions, and preserves the direction of life activity. Within the framework of homeokinesis, life is understood not as static stability but as dynamic balance in motion, where survival depends on constant internal adjustment. Sleep emerges as one of the core mechanisms enabling this adaptive continuity. Human life unfolds as the activity of an open dynamic system, continuously exchanging energy, matter, and information with the environment. At every moment, the organism must regulate competing demands across multiple domains: biological needs, social obligations, and internally defined goals. This regulation requires flexible allocation of limited resources...

  Birth Of A Term And A Shift In Scientific Perspective For a long time, ageing was perceived as a monolithic, inevitable process of general decline, with weakness serving merely as its natural backdrop. Yet in the late 1980s, a word entered the medical lexicon that reshaped the focus of gerontology : sarcopenia . First proposed by Irwin Rosenberg, the term literally means “ poverty of flesh .” Suddenly, it became clear that the loss of muscle mass and strength is not a cosmetic flaw or a passive marker of advancing age. It is a formidable process that determines whether a person can rise from a chair, maintain balance, and, ultimately, how many years of autonomous life remain. Muscles ceased to be viewed only as  instruments of movement; they emerged as a central metabolic and endocrine organ, orchestrating the ageing of the entire organism. The Dynamometer And Stopwatch As Prophetic Tools Today, the dynamometer and the stopwatch in a geriatrician ’s office carry more weight...

If you carry excess weight and want to reduce it safely, every serious path passes through one narrow gate: The volume and speed of your food intake must change. Not the app, not the shoes, not the watch. Health, fitness, sleep, and stress all matter greatly, but the reduction of excess body weight itself begins and ends with what and how you eat. Your metabolism is not a slogan. It is the real inner system that decides what happens to everything you put in your mouth. Some people burn quickly and leak more heat, some burn quietly and store more easily. But whatever your personal speed, two levers are always decisive: How much food goes in  (volume and energy content) How fast your body can process and clear it  (metabolic handling over time) If intake stays high and processing is fast, the body has little reason to touch its reserves. If intake falls and/or processing slows so that nutrients are absorbed and released more gradually, the body must begin to use stored energy. ...

Throughout human history, people have been fascinated by prophetic dreams and visions . These mysterious experiences have appeared in sacred texts, royal courts, folklore, and modern stories alike. They seem to whisper of hidden futures, warning signs, or truths that lie beyond ordinary awareness. Whether interpreted as divine messages, psychological symbols, or glimpses into a larger reality, prophecy continues to stir the imagination because it touches one of humanity’s deepest desires: to understand what lies ahead. One of the most enduring examples of prophetic interpretation appears in the biblical story of Pharaoh’s dreams . In the Book of Genesis , the ruler of Egypt sees two troubling visions. In the first, seven healthy cows emerge from the Nile, followed by seven thin and sickly cows that devour the healthy ones. In the second, seven plump ears of grain are swallowed by seven thin, scorched ears . Pharaoh wakes disturbed and uncertain, sensing that these images carry urgen...

Wet feet disease , better known as trench foot or immersion foot, is a painful reminder of how brutally the environment can damage the human body. It is also part of a longer medical story that begins not in modern war, but on the riverbanks of Europe, where people first learned to use willow bark to relieve pain and inflammation. Over time, this humble tree led to the discovery of salicylates and eventually to modern drugs that still play a role in managing pain and inflammation in conditions like trench foot. For centuries, healers in regions such as Brittany prepared teas and poultices from white willow (Salix alba) bark to treat fever, joint pain, and irritated skin. They did not know about salicin or biochemical pathways, but they observed that willow reduced pain and soothed inflamed tissues. People who worked in cold, wet environments—fishermen, farmers, and sailors—often came home with swollen, painful, water‑logged feet. When available, warm willow decoctions and compress...

  Orthostatic hypotension (OH), also referred to as orthostatic arterial hypotension, is one of the most commonly encountered yet frequently underdiagnosed conditions in clinical medicine. Its consequences range from transient dizziness to life-threatening falls, syncope, and cardiovascular events — making precise definition and early recognition critically important. The traditional, widely accepted definition of orthostatic hypotension is a sustained reduction in systolic blood pressure of at least  20 mm Hg , or diastolic blood pressure of at least  10 mm Hg , occurring within three minutes of transitioning from a supine or sitting position to standing. This definition, endorsed by major cardiovascular and neurological organizations, has formed the foundation of clinical research, diagnostic protocols, and treatment guidelines for decades. However, the standard definition has a fundamental limitation: it captures only one point on a broader physiological spectrum. By...

  Many people with overweight start their journey by adding exercise and leaving food “for later.” It feels fair: move more, weigh less. Yet large, careful trials show that exercise training  without  dietary changes leads to  much less weight loss than expected from calorie calculations . The recent Nature study on multilevel metabolic adaptation to exercise is a clear example: fitness and metabolic health improved, but the actual weight loss was far below what the extra calories burned would predict.  To understand why, imagine your body as a  metabolic factory  with its own baseline settings. For most people with overweight, this factory is not broken or diseased; it simply runs in a more economical “saver” mode: it burns less in the background and stores energy more easily. When you add exercise, this factory responds—but it also defends its balance. How your body compensates for exercise When you start training three or four times per week, seve...
