Yes, social media is making kids depressed
As depression and suicidal thoughts among young people become an alarming global concern, doctors and scientists are trying to understand what role social media might play in this mental health crisis.A new study by researchers at the University of California adds important insights to this ongoing question.The study, published in JAMA Network Open, followed nearly 12,000 children from the ages of 9 to 13. Researchers tracked how much time they spent on social media and also recorded signs of depression during that time.advertisement
What they found was clear: when social media use increased, so did the children's depressive symptoms.But the opposite wasn't true. Children who were already feeling low or depressed were not more likely to start using social media than others.On average, the amount of time pre-teens spent on social media went from 7 minutes a day to 73 minutes a day over the three years.At the same time, their depressive symptoms, which include feelings of sadness, hopelessness, or lack of interest, rose by 35%.

Dr. Jason Nagata, the lead author and associate professor of paediatrics at UCSF, explained that this study is one of the first to track the same children over time.advertisement"These findings provide evidence that social media may be contributing to the development of depressive symptoms,' he said.The study didn't explore the exact reasons why social media causes these emotional changes, but past research points to several possibilities. One is cyberbullying, which means being bullied online. Another is disrupted sleep, especially when teenagers stay up late using phones and miss out on rest.Dr. Nagata's team recently published another study showing that kids who are cyberbullied are more than twice as likely to have thoughts of suicide and also more likely to try substances like alcohol, marijuana, or nicotine.Even though social media can cause harm, it also plays a big part in how children today connect with friends and express themselves. That's why experts recommend helping kids use it in healthier ways rather than banning it completely.The American Academy of Pediatrics suggests families create a Family Media Plan: a guide to help kids and parents decide when and how to use screens.Dr. Nagata advises parents to have open conversations and set screen-free times, like during meals or before bedtime, for the whole family.Must Watch

Study Shows How Plastic Particles In Food, Beverages Can Harm Your Liver
New Delhi: Microscopic plastic particles found in food and beverages may affect glucose metabolism and harm organs such as the liver, according to a new animal study. The findings raise concerns about potential health risks in people who consume microplastics (less than 5 millimetre) and nanoplastics (less than 100 nanometre), which can enter the food chain and end up in seafood and other foods people eat. Previous estimates show that a person may ingest around 40,000 to 50,000 microplastic particles a year through food and beverages, with some estimating exposure to be as high as 10 million particles per year. "Our observations that oral ingestion of polystyrene nanoplastics contributes to glucose intolerance and signs of liver injury, confirm and extend what has been recently reported on the effects of nanoplastics in animal models," said Amy Parkhurst, a doctoral candidate at the University of California, Davis, US. For the study, the researchers focused on exposure via oral consumption to mimic nanoparticles found in food and drink. They gave 12-week-old male mice a standard rodent diet with a daily oral dose of polystyrene nanoparticles. Polystyrene is a widely used plastic commonly found in food packaging and products. The researchers chose a daily nanoparticle dose of 60 mg per kilogram of body weight, based on human exposure levels and earlier mouse studies that showed health effects at similar amounts. "We can't control for all the plastics the mice are exposed to," said Parkhurst. "However, our study design allowed us to see dose-correlated changes since the nanoplastics-dosed group would have a higher exposure." Compared to the control group receiving no polystyrene, the mice consuming nanoplastics exhibited systemic glucose intolerance and elevated alanine aminotransferase, which indicates liver injury. In the mice consuming polystyrene, the researchers also observed an increase in gut permeability and elevated levels of endotoxin, which contribute to liver dysfunction. "Our findings warrant further studies to help inform policy around micro and nanoplastics," said Parkhurst. "Robust scientific evidence plays a key role in shaping monitoring efforts and guiding regulations." The findings will be presented at the ongoing NUTRITION 2025, the flagship annual meeting of the American Society for Nutrition in Orlando.

3 hours of sleep and no fatigue? Scientists uncover the secret of natural short sleepers
How some people function perfectly on 3.5 hours of sleep For decades, the mantra has been the same: adults should aim for seven to eight hours of uninterrupted sleep each night for optimal health, performance, and longevity. From doctors to wellness influencers, the message has echoed across platforms, backed by countless studies linking insufficient sleep to heart disease, diabetes, depression, cognitive decline, and early mortality. But what if this universal advice doesn't apply to everyone? Enter a rare, fascinating group of people who are redefining what it means to be well-rested. Known as natural short sleepers, these individuals thrive on just three to four hours of sleep per night — and not because they're skimping on rest. Rather, they are biologically wired to require less of it. These are not productivity-obsessed workaholics running on caffeine and willpower. They are genetically programmed to complete all the vital functions of sleep in a fraction of the time, waking up refreshed, alert, and high-functioning without any of the side effects typical of sleep deprivation. This condition, called Familial Natural Short Sleep (FNSS), is exceedingly rare and largely misunderstood, but recent breakthroughs in neuroscience and genetics are helping demystify it. From groundbreaking studies to the potential for revolutionizing sleep medicine, the science of short sleepers is gaining momentum — and it may just unlock answers to one of biology's greatest enigmas. How some people function perfectly on 3.5 hours of sleep Natural short sleepers are often highly energetic, productive, and resistant to common health issues associated with insufficient sleep. According to neuroscientist Dr. Ying-Hui Fu at the University of California, San Francisco (UCSF), these individuals don't experience the cognitive fog, irritability, or health decline that plagues typical short sleepers. Natural short sleep isn't a result of lifestyle, stress, or overcommitment. It's genetically driven and often runs in families, hence the term familial in FNSS. In most cases, these individuals sleep between 3.5 to 5 hours a night — every night — and report feeling completely rested and mentally sharp. They don't rely on naps or stimulants to compensate. Their bodies simply don't seem to need more. Though estimates vary, only about 1% of the population may possess this trait, making it an incredibly rare but fascinating subject of study in the world of sleep research. Why some people need just 4 hours of sleep: The genetic blueprint The scientific journey into FNSS began with Dr. Fu's landmark study published in Science in 2009, where her team identified a mutation in the DEC2 gene in members of a family who consistently slept for just 4 to 6 hours a night without adverse effects. Since then, Dr. Fu and colleagues have discovered five key mutations across four different genes involved in regulating sleep, including DEC2, NPSR1, ADRB1, and most recently, SIK3. Each mutation alters the sleep architecture of the brain, effectively condensing the sleep process without compromising its restorative benefits. In a 2022 study published in Neuron, researchers used genetically engineered mice to test the impact of the SIK3 mutation. The mice exhibited significantly reduced sleep times without observable physical or cognitive impairment. These findings strongly suggest that FNSS is not just a fluke — it's a biologically viable alternative to conventional sleep patterns. While each mutation alone only slightly reduces sleep needs, stacking them together may have cumulative effects, a hypothesis currently under investigation. If confirmed, this could pave the way to replicating FNSS-like effects safely in individuals with sleep disorders. Can short sleep genes treat insomnia The implications of this research extend far beyond curiosity. Sleep disorders like insomnia, narcolepsy, and sleep apnea affect hundreds of millions globally. Understanding the biological mechanisms that allow short sleepers to thrive on less sleep could revolutionize sleep medicine. Dr. Fu's team believes that, in the future, therapies could be developed to mimic or activate these gene mutations in people suffering from insomnia or irregular sleep cycles. This would allow them to achieve restorative sleep in shorter durations, potentially improving quality of life for those who cannot sustain long sleep hours due to work schedules, health issues, or neurological conditions. Professor Clifford Saper, a renowned sleep scientist at Harvard Medical School, supports this line of inquiry, emphasizing that we are only scratching the surface of sleep genetics. 'If we can understand how to safely 'accelerate' the sleep process, we could one day provide relief to millions who struggle with poor sleep,' he notes. The dark side of sleeping less (if you're not genetically wired) Despite the allure of being able to function optimally on minimal sleep, it's crucial to underscore that Short Sleep Syndrome is not something you can train yourself into. Most people who sleep less than six hours a night accumulate sleep debt, which can lead to severe health consequences over time. A 2022 UK Biobank study involving over 7,800 participants found that individuals in their 50s who slept less than five hours per night were 20% more likely to develop multiple chronic conditions, including: Cardiovascular disease Type 2 diabetes Depression Obesity Dementia Moreover, sleep deprivation is associated with weakened immune function, poor memory, mood instability, and a higher risk of accidents. So unless you're genetically tested and confirmed to be a natural short sleeper, cutting back on sleep can be dangerous — not admirable. Why sleep matters: The body's restoration cycle To understand why most people need 7–8 hours of sleep, it's important to know what happens during that time. Sleep is not a passive state; it's a dynamic biological process governed by our circadian rhythm, the body's internal 24-hour clock. Sleep consists of multiple stages: Light Sleep (N1 and N2) – Helps the body relax and transition. Deep Sleep (N3) – Critical for physical restoration, tissue repair, and immune function. REM Sleep – Vital for learning, memory consolidation, and emotional processing. During a typical night, we cycle through these stages four to six times. For natural short sleepers, research suggests that their bodies compress these cycles, achieving full restoration in a shorter window. They may experience a more efficient distribution of deep sleep and REM stages, allowing them to complete the 'tasks' of sleep at high speed — like a compressed file that contains all the data in less space. Are you a natural short sleeper? Wondering if you might be part of this rare elite group? According to sleep researchers, natural short sleepers exhibit several consistent traits: Sleep just 3–5 hours per night and wake up feeling fully rested Never feel the need to nap or 'catch up' on weekends Show no signs of fatigue, brain fog, or irritability Maintain excellent health and cognitive function Often display high energy, optimism, and productivity Still, self-diagnosis is not recommended. If you suspect you might be a natural short sleeper, consult a sleep specialist and undergo polysomnography or genetic testing to confirm. Many people mistakenly believe they're short sleepers but are, in fact, sleep-deprived. The future of sleep: Genetic engineering or natural evolution? With genetic research accelerating, it's not far-fetched to imagine a future where gene-editing technologies like CRISPR could give people FNSS-like traits. But such advancements are years — if not decades — away, and ethical considerations abound. In the meantime, scientists are using the study of FNSS to understand how sleep works at the molecular level, which could have applications in fields ranging from neurodegenerative disease treatment to space travel, where managing sleep in constrained environments is vital. Ultimately, natural short sleepers challenge one of the most fundamental assumptions of modern medicine — that all humans have the same biological need for rest. And in doing so, they open the door to a future where sleep is not just a necessity, but a personalized experience based on genetics.

Invisible parasites roam on your face every night while sleeping. Could they be causing skin problems?
While sleep is often viewed as a peaceful escape from the demands of the day, it's also when an invisible ecosystem on your face springs to life. Every night, microscopic creatures called Demodex mites emerge from your pores. These eight-legged parasites, which reside around the outer part of hair follicles, feed on the oily substances your skin naturally produces. You can't see them or feel them, but nearly every adult human hosts these mites. Measuring just 0.15 to 0.4 millimeters in length — smaller than the tip of a needle — they are a permanent and largely unnoticed presence on our skin. Up to five mites can occupy just one square centimeter of your face. And despite the unsettling thought, experts say their presence is typically harmless. Why They're on Your Skin According to Alejandra Perotti, an associate professor of invertebrate biology at the University of Reading, the mites become most active while you sleep. 'While we are sleeping, they come out and are very happy, mating, visiting relatives, walking on our faces. The moment we wake up, they go back inside the pore,' Perotti said. These mites aren't freeloaders. In fact, they perform a sort of maintenance service by clearing out pore blockages. In return, the human body provides melatonin — a sleep-inducing hormone produced in the skin — which gives the mites the energy they need to survive. Their ability to resist ultraviolet light also helps them thrive, as UV rays typically damage small organisms' DNA. When Problems Arise Though usually harmless, Demodex mites can sometimes cause skin and eye issues, particularly when their population increases uncontrollably. Dr. Richard Locksley, professor of medicine at the University of California, San Francisco, explained that overgrowth — a condition known as demodicosis — is more common in people with weakened immune systems, such as older adults or those undergoing chemotherapy. In such cases, the body may react to both the mites and the bacteria they carry, leading to inflammation. Dr. Roberto Ricardo-Gonzalez, a dermatologist also at UCSF, noted that this inflammation can appear as rosacea, acne, flaking, or dryness, especially on oily areas of the face like the cheeks and forehead. Doctors can diagnose mite-related conditions by examining skin or eyelash samples under a microscope. Dr. Cory Lappin, an optometrist in Ohio, pointed out that demodex waste and eggs often accumulate at the base of the eyelashes, causing dryness, itching, and even recurring sties in some patients. Reducing the Risk Fortunately, preventing mite overgrowth is often as simple as practicing good hygiene. Experts recommend gently washing the face each night with a cleanser to remove excess oil and debris. It's also advised to remove makeup and false lashes before sleeping to avoid irritation around the eyes. Those with acne-prone skin may benefit from using a topical retinoid once or twice weekly, but moderation is key. Excessive cleansing or skin dryness can disrupt the skin's natural barrier, prompting the mites to multiply. Additionally, a consistent sleep schedule can help regulate sebum production, which acts as food for these parasites. In cases where overgrowth leads to persistent irritation, dermatologists may prescribe topical or oral ivermectin to bring the mite population under control, although total eradication isn't possible. In 2023, the FDA also approved medicated eye drops specifically to treat eyelid inflammation caused by demodex mites. Demodex mites have likely lived on human skin for centuries, passed on shortly after birth through close contact, especially from mothers. Yet, as Perotti's 2022 research suggests, these mites may be undergoing what she describes as 'a long-term evolutionary death.' This means that, while they're still here now, their long-term survival may be uncertain. Despite how strange it may sound, these tiny organisms are just another part of the human body's ecosystem — mostly silent, invisible, and surprisingly useful.
