The change of season affects more than the temperature outside. It also changes the environment our skin is exposed to every day. As the air becomes cooler and, in some settings, drier, our hands can be among the first areas where we notice tightness, roughness or dryness. The skin acts as a protective barrier that helps limit water loss and protects deeper tissues from external factors. Lower temperatures and lower humidity can affect this barrier, making the skin more susceptible to dryness and irritation. What changes as temperatures drop? Environmental humidity affects the amount of water retained in the outermost layer of the skin. Research suggests that changes in temperature and relative humidity can influence skin hydration and barrier function. That does not mean everyone's skin will automatically become dry in autumn. The response varies and can also depend on climate, water exposure, cleansing habits and skincare products. Our hands have another disadvantage: they are wa...

Δεν είναι μόνο η γυμναστική που μετρά ως κίνηση. Μέσα σε μια συνηθισμένη ημέρα σηκωνόμαστε από την καρέκλα, περπατάμε μέχρι την κουζίνα, ανεβαίνουμε σκάλες, κουβαλάμε μια τσάντα, τακτοποιούμε το σπίτι ή απλώς αλλάζουμε θέση. Πολλές από αυτές τις κινήσεις γίνονται σχεδόν αυτόματα και δεν τις θεωρούμε «άσκηση». Παρ' όλα αυτά, αποτελούν μέρος της συνολικής σωματικής δραστηριότητας της ημέρας. Το σώμα κινείται και έξω από το γυμναστήριο Όταν ακούμε τη φράση «σωματική δραστηριότητα», μπορεί να σκεφτόμαστε αμέσως το τρέξιμο, το ποδήλατο, τα αθλήματα ή μια προπόνηση. Στην πραγματικότητα, η κίνηση έχει πολλές μορφές. Το περπάτημα για μια μικρή απόσταση, οι σκάλες, οι δουλειές του σπιτιού και οι μετακινήσεις μέσα στη μέρα προσθέτουν χρόνο κίνησης. Ο Παγκόσμιος Οργανισμός Υγείας περιλαμβάνει στη σωματική δραστηριότητα όχι μόνο την άσκηση, αλλά και την κίνηση που γίνεται στη δουλειά, στις μετακινήσεις, στον ελεύθερο χρόνο και στις καθημερινές εργασίες. Γιατί έχουν σημασία οι μικρές κινήσεις; ...

Exercise is not the only form of movement that matters. During an ordinary day, we get up from a chair, walk to the kitchen, take the stairs, carry a bag, tidy the house or simply change position. Many of these movements happen almost automatically, so we do not always think of them as physical activity. Yet they all contribute to how much we move throughout the day. The World Health Organization defines physical activity as any bodily movement that requires energy, including movement during work, transportation, leisure and household tasks. The body moves outside the gym When we hear the words “physical activity”, we may immediately think of running, cycling, sports or a workout. But movement has many forms. Walking to a nearby place, taking the stairs, doing housework or moving around at work can all add activity to the day. WHO specifically includes transportation and everyday household tasks as forms of physical activity. Why do small movements matter? A single short walk or trip u...

Every time we eat, a process begins that continues for hours without us having to think about it. Food travels through different organs, mixes with digestive fluids and is gradually broken down so the body can absorb the nutrients it needs. Digestion is not only about the stomach. From chewing and saliva to the small and large intestines, every stage has a different role. It all starts in the mouth Digestion begins with the first bite. Chewing breaks food into smaller pieces and mixes it with saliva, making it easier to swallow. Saliva also contains enzymes that begin breaking down some carbohydrates while the food is still in the mouth. When we swallow, the tongue moves the food towards the throat and then into the esophagus. The esophagus moves food along Food does not simply travel down the esophagus because of gravity. Muscles in its walls contract in sequence, creating a movement called peristalsis. This pushes the food towards the stomach. Once swallowing begins, much of this pro...

After spending enough time in the bath or swimming pool, our fingers start to look different. The skin on our fingertips becomes covered in small wrinkles. For years, the simple explanation was that the skin was simply absorbing water and swelling. In reality, the process is a little more interesting. What happens to our fingers? Finger wrinkling after being in water is an active process linked to the autonomic nervous system. When our fingers stay underwater, the small blood vessels underneath the skin constrict. This reduces blood flow and volume in the area, causing the skin to pull inward and form the familiar wrinkles. So it is not simply because the skin absorbs water? Not exactly. Water plays a role in starting the process, but the wrinkling itself appears to depend largely on the function of nerves and blood vessels. In fact, fingers with disrupted nerve supply may not develop normal water wrinkles. This is one reason the phenomenon has also been used as a simple test of autono...

When we feel anxious, we may suddenly notice that we are breathing faster, more shallowly or that it feels difficult to take a “normal” breath. Why does this happen? Our breathing is closely connected to the way our body responds to stress and tension. What happens to the body when we feel anxious? When we see a situation as threatening or stressful, the body activates systems that prepare us to deal with it. This response can also affect our breathing. We may start breathing faster or simply become more aware that our breathing has changed. Why can it feel like we are not getting enough air? When breathing changes during intense anxiety, we may experience shortness of breath or feel that we cannot take a deep enough breath. The relationship between anxiety and breathing is complex. Research shows that some anxiety disorders are linked to changes in both breathing and the way we perceive physical sensations. This means that we may pay much more attention to our breathing when we are an...

Υπάρχουν μέρες που το μόνο που θέλουμε μετά από μια κουραστική ημέρα είναι λίγη ησυχία. Μπορεί να μην έχουμε διάθεση να μιλήσουμε, να απαντήσουμε σε μηνύματα ή να βρεθούμε με άλλους ανθρώπους. Αυτό δεν σημαίνει απαραίτητα ότι δεν θέλουμε τους ανθρώπους γύρω μας. Μερικές φορές, απλώς χρειαζόμαστε λίγο χρόνο χωρίς κοινωνικές απαιτήσεις. Γιατί η κούραση μπορεί να μας κάνει να αναζητούμε ησυχία; Η κοινωνική επαφή χρειάζεται ενέργεια, ιδιαίτερα όταν η ημέρα μας ήταν ήδη γεμάτη υποχρεώσεις, συζητήσεις και αποφάσεις. Όταν είμαστε κουρασμένοι, μπορεί να θέλουμε λιγότερα ερεθίσματα και περισσότερη αίσθηση ελέγχου πάνω στον χρόνο μας. Έρευνα στην καθημερινή ζωή έχει δείξει ότι η μοναχικότητα και η κοινωνική επαφή εναλλάσσονται και μπορεί να λειτουργούν ως τρόποι ρύθμισης της ενέργειας και των κοινωνικών αναγκών. Το να θέλουμε να είμαστε μόνοι δεν σημαίνει ότι είμαστε αντικοινωνικοί Το να επιλέγουμε λίγη ώρα μόνοι μας είναι διαφορετικό από την κοινωνική απομόνωση. Η εθελοντική μοναχικότητα μπορεί...
