When we do not get enough sleep, tiredness is usually the first thing we notice. But sleep is involved in many normal processes in the body, and the skin is part of that picture too. Research suggests that sleep quality and duration are linked to skin barrier function, water loss from the skin and some aspects of skin appearance. That does not mean that one bad night will permanently change our skin. Regularly getting poor-quality sleep is a different matter. Sleep and the skin barrier The skin barrier is the outer protective layer of the skin. One of its important roles is helping the skin retain moisture while protecting it from external factors. In a study comparing women with different sleep quality, good sleepers showed better skin barrier function and recovery than people with chronically poor sleep. This matters because when the skin barrier is not working as well, the skin can lose more water. Can lack of sleep affect how our skin looks? The same study found differences in some...

Πρωταθλητής Muaythai, μέλος της Εθνικής Ομάδας, πολιτικός μηχανικός, επιχειρηματίας, προπονητής και πατέρας. Ο Δήμος Ασημακόπουλος έχει χτίσει μια πορεία στην οποία ο πρωταθλητισμός δεν αποτελεί ξεχωριστό κεφάλαιο από την καθημερινή ζωή — αλλά τον τρόπο με τον οποίο την αντιμετωπίζει.
Ο Δήμος Ασημακόπουλος σε αγωνιστική δράση.
Γεννημένος το 1993 και μεγαλωμένος στην Πάτρα, ασχολείται με το Muaythai από το 2010. Στη διάρκεια αυτών των χρόνων έχει εκπροσωπήσει την Ελλάδα σε μεγάλες διεθνείς διοργανώσεις, έχει ανέβει επανειλημμένα στο βάθρο και έχει αγωνιστεί απέναντι σε αθλητές υψηλού επιπέδου από όλο τον κόσμο.
Από την Πάτρα στην Εθνική Ομάδα
Η παρουσία του στην Εθνική Ομάδα δεν ήταν περιστασιακή. Η Ελληνική Ολυμπιακή Επιτροπή τον συμπεριέλαβε στην Team Hellas για τους 3ους Ευρωπαϊκούς Αγώνες της Κρακοβίας το 2023, στην κατηγορία Men's Combat -67 kg. Η διεθνής διαδρομή του είχε ήδη αρχίσει αρκετά χρόνια νωρίτερα. Στο Ευρωπαϊκό Πρωτάθλημα του 2017 στο Παρίσι κατέκτησε το χάλκ...

The first reaction can be almost immediate: a sharp gasp, rapid breathing, an intense sensation of cold and a strong urge to get out. This is more than simple discomfort. Sudden exposure to very cold water triggers a series of automatic physiological responses. This is known as the cold shock response. It can affect breathing, heart function and blood pressure, particularly when exposure to cold is sudden. The first reaction may be a sudden gasp When the skin comes into sudden contact with very cold water, temperature-sensitive receptors send signals to the nervous system. The body responds by activating mechanisms designed to deal with the sudden thermal stress. One of the most noticeable responses is an involuntary gasp, often followed by rapid and deeper breathing, known as hyperventilation. This matters especially in water because losing control of breathing can make it harder to remain calm and maintain effective breathing. What happens to the heart and blood vessels? Cold shock a...

Sponsored content by OLDSPELL For a man with a busy schedule, physical activity is often associated with the gym, running or a planned workout. But movement during the day does not start and end there. Walking to work, taking the stairs, going for a short walk during a break or doing things around the house are also forms of physical activity. The World Health Organization notes that physical activity can come from work, transport, exercise, leisure and everyday household tasks. Movement does not always have to look like a workout The idea that a man is only physically active when he is at the gym does not capture the whole picture. Some movement can become part of an ordinary routine. A man who spends long hours at a desk, for example, can get up more often, walk short distances or take the stairs when practical. This does not mean that a few minutes of walking replace a structured workout. It simply means that physical activity can be made up of different moments throughout the week....

A mirror is such an ordinary part of everyday life that we rarely stop to think about what happens when we look at our own face for an extended period of time. We are not simply seeing an image. The brain is processing a face it knows extremely well — our own. How we perceive that face can be influenced by familiarity, attention, previous visual experience and the way we feel about ourselves. Our face is not just a static image Whenever we look in a mirror, the brain combines incoming visual information with an internal representation of our own face. Eye-tracking research suggests that people may look at their own face differently from the way they look at another person's face. Familiarity changes perception The brain adapts to visual information that it encounters repeatedly. In face perception, this process of visual adaptation can influence how features, expressions and even aspects of facial identity are perceived. This does not mean that a mirror actually changes our face. R...

That moment when we put down our fork and realize we do not want another bite may feel simple. Biologically, however, fullness is the result of a continuous conversation between the digestive system and the brain. The body does not simply wait for the stomach to become «full». As we eat, mechanical and chemical signals from the gastrointestinal tract provide the brain with information about the amount and composition of the meal. The stomach starts sending signals As food enters the stomach, it expands and activates mechanisms that detect tension in its walls. These signals contribute to the sensation that we have eaten enough. But stomach distension is only part of the picture. Nutrients reaching the digestive tract also trigger chemical and hormonal signals involved in appetite regulation. The brain receives the message Signals from the gastrointestinal tract communicate with neural circuits involved in hunger and satiety. This creates what is often described as the gut–brain axis. S...

Our name is one of the most familiar words we hear. We have been hearing it since childhood, and over time it has become closely linked to our identity, our relationships and our everyday experiences. That may be one reason why our name can capture our attention even when we are not consciously listening for it. The effect is especially noticeable in busy environments. We may be talking to someone, surrounded by several conversations, and suddenly notice that someone has said our name. The brain appears to give particular priority to information that is personally meaningful. Why does our name stand out? Auditory attention does not work like a simple switch. Even when we focus on one conversation, the brain continues to process at least some information coming from the surrounding environment. The so-called cocktail party effect describes this ability to focus on one source of sound while still detecting certain meaningful stimuli in the background. Our own name is one of the classic e...
