There are people obsessed with doing a post-Christmas “detox” based on juices. Your body has something to say about it

In the era of scroll infinite, the TikTok algorithm seems to have found the potion of eternal youth in 250 milliliter format. One day is the water with lemonother apple cider vinegar and, more recently, the beet shots either beet shots. Under labels like #detox or #guthealth, influencers with millions of followers promise to “cleanse” the body, flatten belly and speed up metabolism with a simple morning gesture. However, behind the careful aesthetics and pseudoscientific jargon, the medicine is forceful: your body is not a room that needs a three-day “cleaning spree”, but a complex system that already knows how to take care of itself if we do not hinder it. The viralization of deception. Behind the fascination with miracle cures operates a multi-billion dollar industry that capitalizes on consumer vulnerability. after the excesses, according to a report in The Washington Post. However, the phenomenon transcends conventional marketing to establish itself on social networks with alarming data: an analysis of Eating Behaviors Magazine on content on TikTok revealed that 97% of videos promoting supplements and dietary products lack any scientific basis. “Microbiota“. This gap between digital popularity and medical evidence evidences a public health problem where misinformation is monetized on a large scale. According to this same study93.6% of content creators do not mention their credentials, and the vast majority of promotions (95.7%) do not even clarify whether they are sponsored by brands. We are literally entrusting our metabolic health to strangers who they use terms as “microbiota” or “low-grade inflammation” to construct an illusion of rigor that sells much more than the boring reality of eating whole vegetables. The “detox” myth. Why do we feel “better” after a juice program? According to expertsit is not because of the mystical properties of celery or cayenne, but because we have stopped consuming ultra-processed foods, added sugars and alcohol for a few days. However, the concept of “detoxifying” the body with fluids is, biologically, nonsense. Dr. Tinsay Woreta maintains that the human body It operates with a highly efficient natural filtration system, where lungs, intestines and kidneys constantly eliminate toxins and pathogens. In tune, Mayo Clinic highlights the lack of scientific evidence on the alleged accumulation of waste requiring external “washing”; On the contrary, the institution warns that extreme cleansing, such as colon cleansing, poses an unnecessary danger that can lead to dehydration, infections or even rectal perforations. What science says (and TikTok remains silent). Far from being harmless, these diets can be counterproductive. According to a study from Northwestern Universityeliminating fiber to consume only juices—even for just three days—drastically alters the oral and fecal microbiome, increasing bacteria linked to inflammation and cognitive decline. Fiber is food for “good” bacteria that produce anti-inflammatory compounds; Without it, sugar-loving bacteria multiply. Even the “king” of home remedies, apple cider vinegar, has fallen from its pedestal. The famous study that supported its benefits for losing weight was retracted due to inconsistencies in the data and statistical errors. The reality is that taking it on an empty stomach can irritate the esophagus and permanently damage the enamel of your teeth. What is the real alternative? If the goal is longevity and liver health, science proposes replacing the “shot” with sustainable habits: Fruit is eaten, not drunk: Longevity expert Peter Diamandis a vital advice: If you like oranges, eat them whole. By juicing, you destroy fiber, which worsens satiety and triggers sugar absorption. Look North: As we obsess over supplements, the “new Nordic diet” is winning the battle to the Mediterranean in some studies. This pattern (based on canola oil, whole grains like rye, and berries) reduces the risk of fatty liver by a staggering 58%. Strength versus fragility: Walking is great for the heart, but to age with autonomythe body needs weights or elastic bands. Strength exercise is the only way to stop sarcopenia (muscle loss) and release myokines, proteins that protect the brain against Alzheimer’s. Be careful with him Protein Chic: The trend of adding protein to everything (coffees, yogurts, bars) is often an unnecessary expense. Dr. Stuart Phillips points out that excess protein It doesn’t build muscle on its own—training does that—and can unnecessarily strain the kidneys and liver. Health has no shortcuts. In short, science suggests that the best “cleanse” is one that is not done intermittently. As the experts consulted by The Washington Post concludea week-long juicing regimen cannot undo the damage of a sedentary lifestyle or a regular poor diet. The next time you watch a video with a magenta liquid promising miracles, remember: your liver is already working at full capacity while you sleep. What he really needs is not a trendy juice, but rather that you give him three days of weekly alcohol rest, a diet rich in fiber and, perhaps, that you stop searching on your cell phone for what can only be found in the market and in the gym.

We are so hooked on smartphones that Gen Z has found its own “detox”: sending letters again

I remember perfectly the first letter I wrote. My best friend had moved to a town in Ciudad Real and the distance, back then, was measured in the time our parents allowed us to use the telephone line. We couldn’t spend hours on the phone, so we decided to tell each other our lives by email. Every week, a letter. That exchange of envelopes lasted as long as it took us to have a computer tower and internet access. Then the great migration arrived: Messenger, Fotolog, Tuenti, Facebook, Instagram, WhatsApp… Today we send photos to each other in real time and make video calls. If someone had told those two girls that technology would be the glue of their friendship, they wouldn’t have believed it. In the middle of 2025, history seems to be closing an unexpected circle. We live in the era of immediacy, where WhatsApp messages coexist with saturated emails that ask for mercy under the tagline ASAP (as soon as possible). The saturation is such that the phone’s storage warns every so often that there is no space, while the messages are interspersed with alerts, reminders and the white noise of a hyperconnected world. Faced with this “uncontrolled beat of the digital rush”, Generation Z has rescued the habit of being penpals or pen pals. Stamps.com Data reveal that almost 48% of this generation sends physical correspondence at least once a month, breaking the myth of the young person unable to tear themselves away from the screen. On Instagram, the hashtag #penpal already exceeds 1.3 million of posts, while TikTok becomes a catalog of calligraphy and sealing wax. It’s not about sending a text; It is a “slow ritual” where both the content and the container count. Neuropsychology explains this return with crystal clear clarity. According to psychologist Noelia Barroso, interviewed by El EspañolWhile digital notification triggers a rapid and volatile dopamine pulse, waiting for a letter activates multisensory processes that generate much more stable oxytocin peaks. The weight of the paper and its aroma link deep memories that the pixel simply ignores. This phenomenon is, in essence, a measure of mental health. The Tunheim report points out that 44% of young people have reduced their screen time out of sheer exhaustion, searching through the mail for a necessary “digital detox.” The expert Victoria López, in Hello magazinedefines it as a form of “constant presence”: a physical object that lives on a shelf and that, unlike a chat, has a mass and texture that make it indestructible against oblivion. A love of the tangible This “historical nostalgia” for times they did not live in is an emotional compass towards the authenticity that the algorithm has worn away. The impact is such that the market is transforming. Pinterest Predictions 2026 indicates that searches of “beautiful stamps” have risen 105% and that letter writing will be considered a “performative art.” However, the road is uneven. While in the United States 31% of young people trust the email for securityIn Europe we are experiencing radical contrasts. Denmark has stopped delivering letters after 400 years due to extreme digitalization, but even so, young Danes send three times more letters than the rest of the population through private companies, according to The Guardian. Even the connection with our own future has changed. Tools like FutureMe either Letter to Yourself They allow you to send messages to yourself ten years from now. It is an exercise in “realistic optimism” to connect with the present and relativize the current crises, a way of “leaving a mark.” In the end, Generation Z is not technophobic; They are simply the first to understand that technology is a means, not an end. According to sociologist Narciso Michavila in La Vanguardiathey look for the physical because hyperdigitization no longer surprises them; It is its natural state and, therefore, it lacks the value of the extraordinary. This need to touch the memory has crystallized into another practice that is sweeping networks: junk journaling. It’s not just collecting papers; is, as WeLife explainsthe art of turning recycling into a personal diary to reconnect with yourself. The New York Times collect how young enthusiasts They rescue everything from traffic tickets to museum tickets or bread wrappers for their aesthetic value. “It’s a challenge to find things you would normally throw away and use them in a fun way,” its practitioners explain. In a world consumed by screens, the junk journal forces hands to still and embrace the silence of cutting and pasting, creating physical time capsules that, unlike the cloud, do not depend on a server to exist. In a context where generative AI can write thousands of emails in seconds, human handwriting is positioned as the last bastion of the unrepeatable. The handwritten letter has ceased to be a formality and has become an object of resistance against the attention economy. Some things don’t go out of style, they just wait for us to need them again. Today, in 2025, it seems that Gen Z has found in a sealed envelope the calm that fiber optics failed to give them. Image | freepik Xataka | Harvard bought a cheap copy of the Magna Carta in 1946.

The digital detox has been fashionable for years. It’s time to start talking like what is: a myth

Social networks have helped us in many aspects of our life, allowing us for example to strengthen some social relationships, or taking a way to express our creativity. But all this has come with a price to pay. A cost that has noticed our mental health, which has led many to try with a time to “digital detoxification.” The problem is that it may not be too useful strategy. Not so effective. Withdraw a time from social networks It is not an effective “disconnection strategy”according to a meta -analysis carried out by a Belgian team of researchers from the universities of Antwerp and Gante, at least if we are looking to improve Our well -being. The good news: at least we do not have indications that disconnection does us badly. “The findings (…) suggest that temporarily separating ourselves from social networks may not be the approximation (…) optimal to improve individual well -being,” Write the teamwhich also points out in his study the need to continue research on alternative disconnection strategies. Ten studies. The new work is a meta -analysis, that is, a “quantitative study of studies.” The team conducted a systematic search for scientific literature that addressed the relationship between social media abstinence and one or more than three variables: positive and negative affections, and vital satisfaction. They found 10 quantitative works with a total sample of 4,674 participants. The analysis showed no significant effects of refraining from social networks in any of the three variables studied. The team also did not find indications that the duration of the period of “Digital detoxification“It will be relevant. The details of the study were published In an article In the magazine Scientific Reports. Need to investigate more. The team emphasizes the need to advance in research on this issue. According to the team itself, the study presents one of the usual problems in the meta -analysis, and is the diversity in the methodologies followed by the works included in it. A radical change. Social networks have remarkably changed how we interact with technology, for better and for worse. The problems that this poses have appeared so suddenly that our ability to adapt, to look for solutions with which to repair the possible damage has exceeded in many contexts.
