6 worst habits that could be harming your looks: Harvard liver specialist urges to stop these lifestyle mistakes
Looking younger isn't just about
skincare
or genetics—it's also about the
daily habits
that shape your overall health. Dr. Saurabh Sethi, a liver specialist trained at Harvard and Stanford, recently shared science-backed advice on how certain lifestyle choices can speed up the aging process. From what you eat to how you manage stress, these factors can directly impact how old you look and feel, having broader implications for long-term health.
In a YouTube video, Dr. Sethi outlined six habits that could be making you age faster—and what you can do to reverse the damage.
Smoking: The Fast Track to Premature Aging
According to Dr. Sethi, smoking tops the list as the most damaging habit when it comes to accelerating the aging process. It harms the skin's elasticity and reduces blood flow, leading to early wrinkles and a dull complexion. More importantly, it introduces harmful toxins that impact overall organ health, including that of the liver.

Excessive Alcohol Consumption
Drinking too much alcohol is another major factor that contributes to visible signs of aging. Alcohol dehydrates the skin, causes inflammation, and can damage liver function over time. While occasional consumption might not be harmful, consistent overindulgence can lead to long-term effects on both appearance and internal health.
Poor Sun Protection
While sunlight is essential for vitamin D synthesis and general well-being, Dr. Sethi emphasized that unprotected exposure during peak hours—especially from 10 a.m. to 4 p.m.—can speed up skin aging. Failing to use sunscreen or wear protective clothing like hats can result in sunspots, fine lines, and an overall older look. He advised mindful sun exposure and proper protection as crucial for maintaining youthful skin.
Chronic Dehydration
Maintaining proper hydration is especially important during warmer months, Dr. Sethi noted. Insufficient water intake leads to dry, sagging skin and an overall tired appearance. Staying hydrated supports skin elasticity and brightness, helping people look and feel younger.
High Intake of Processed Foods and Sugar
A diet filled with sugary and processed foods not only impacts metabolism but also contributes to skin problems and inflammation. Dr. Sethi pointed out that excess sugar can damage collagen, a protein responsible for skin firmness, which leads to premature aging signs like sagging and wrinkles.
Unmanaged Stress
Dr. Sethi also highlighted chronic stress as a silent contributor to aging. Long-term stress can disrupt hormonal balance, affect sleep, and leave visible marks on the face. He shared that he personally practices "Bhramari Pranayama"—a type of yogic breathing known as the humming bee breath—to manage stress and improve overall wellness. Such breathing techniques can help calm the mind and improve emotional well-being.
Dr. Sethi's message is clear: Small but consistent
lifestyle changes
can go a long way in preserving both youthfulness and internal health. From quitting smoking to practicing stress-reducing techniques, these evidence-based suggestions aim to help people age gracefully—inside and out.

Delhi consumer commission holds lab liable for faulty test report that led to hospitalisation
New Delhi: A faulty lab test report that triggers panic and emergency hospitalisation amounts to a deficiency in service, Delhi State Consumer Disputes Redressal Commission (DSCDRC) has said, asking a private pathology laboratory to compensate the affected customer. In a recent ruling, the state commission upheld the findings of a district consumer forum against Dr Lal Pathlabs and observed that its "grossly erroneous results constitute a failure to perform basic testing accurately, causing undue distress and unnecessary hospitalisation." Dismissing the appeal filed by the lab, the bench of Justice Sangita Dhingra Sehgal (president) and Pinki (member judicial) noted that if "the tests carried out by a laboratory are defective and erroneous, then the diagnosis by the doctor will not be correct, and the patient will not get the proper treatment. The medicines prescribed based on a wrong test report and diagnosis may lead to fatal results for the patient. When a patient's urea levels are reported at more than ten times the normal range, triggering emergency hospitalisation and profound distress, the laboratory cannot retreat behind semantic arguments about its limited role in the diagnostic chain." According to the complainant, on receiving the test report showing abnormally high creatinine levels at 8.39 mg/dl and urea at 189 mg/dl, while the reference range of creatinine is 0.6-1.3 mg/dl and urea at 6-21 mg/dl, the treating doctor directed immediate hospitalisation and further tests while preparing for a procedure. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 임플란트 29만원 이벤트 임플란트 더 알아보기 Undo However, further tests within 24-48 hours revealed normal readings. The same tests were conducted at two other private labs, which also showed the patient's parameters to be within the normal range. "It is to be noted that the medical expenses incurred by the respondent were directly attributable to the appellant's erroneous report, which falsely indicated life-threatening conditions and necessitated emergency hospitalisation ," the commission said. Rejecting the challenge to the award of Rs 3.5 lakh as compensation payable by the laboratory, the state commission pointed out that being "misdiagnosed with life-threatening conditions and undergoing unnecessary hospitalisation constitutes severe psychological trauma. The mental agony and physical suffering cannot be understated. Also, the prolonged litigation justifies litigation costs as a component of compensation. " Dr Lal Pathlabs said that there was no deficiency in service and that the tests were conducted under strict quality control protocols.

Why General Mills discontinued cereals like Medley Crunch and Chocolate Peanut Butter Cheerios
This week, cereal lovers everywhere spotted empty shelf space where beloved Cheerios once stood and must be wondering why. General Mills confirmed that Honey Nut Cheerios Medley Crunch, Chocolate Peanut Butter Cheerios, and the 18‑oz size of Honey Nut Cheerios Minis have officially been discontinued, as reported by ABC News. While the smaller 10.8‑oz minis remain available, these full‑size options have been quietly phased out. On social media, disappointment surged. An anonymous cereal blogger first flagged the pull via Instagram, which spread quickly through Reddit and other fan forums. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Access all TV channels anywhere, anytime Techno Mag Learn More Undo On their website, these products have nearly 200 five‑star reviews for Medley Crunch and some 50 for Chocolate Peanut Butter Cheerios. They have built strong niche followings, but not enough to keep the products afloat, especially as newer, more profitable lines are replacing them. Why did General Mills discontinue the popular breakfast cereals? Live Events Though the company hasn't pinpointed a single reason, its statement cites three key factors: demand declines, ingredient sourcing issues, and ongoing supply‑chain constraints. General Mills clarified it must maintain 'high quality and competitive pricing,' hinting that production costs or complexity may no longer justify these lines amid a shifting portfolio. That shift appears strategic. Recent commentary in Fast Company highlights General Mills' refocus on protein‑enhanced offerings like the new Cheerios Protein cinnamon, strawberry, and cookies‑and‑cream flavors, alongside the revived Frosted Lemon Cheerios for summer. In effect, the company is prizing innovative, health‑and‑wellness aligned cereals over legacy indulgent flavors. Another possible driver is broader dietary pressures. Rising awareness of sugar, fat, and sodium in breakfast cereals, which experienced an 11 % increase in sugar content and may exceed 45 % of the American Heart Association's daily limit in a single bowl, has prompted industry players to reevaluate indulgent SKUs. Discontinuing richer formulas like Chocolate Peanut Butter and Medley Crunch could be a response to healthier consumer trends, regulatory scrutiny, or internal nutrition targets. General Mills continues to reassure fans that discontinued items aren't gone forever. In response to ABC News' query, it stated that much like Frosted Lemon Cheerios, which returned by popular demand, they continue to listen to their fans as they evolve their offerings.

City docs debate new ligament op method
Kolkata: A 31-year-old man underwent arthroscopic ACL (anterior cruciate ligament) reconstruction using a biological augmentation implant, combined with the patient's own tendon graft. Doctors at Woodlands Hospital said this was the first case of a biological implant being used in such a surgery in Bengal. They said recovery takes about three months, compared to the conventional procedure where recovery could take a year. The ACL is a ligament in the knee that helps stabilise the joint by preventing the shin bone from sliding too far forward relative to the thigh bone. "This biological implant promotes faster graft healing and bone integration. While it is a boost for athletes, where long lay-offs often mean muscle loss and mental strain, it can be used on others with ligament tears," said orthopaedic surgeon Arnab Karmakar, who performed the procedure on Thursday. Debraj Das, who had the surgery, is not a professional athlete, but he regularly swims and goes on hikes. He was discharged on Friday. While a section of doctors are sceptical about this new device, which came to India about six months ago, it has been used in the US for a few years now. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like What She Did Mid-Air Left Passengers Speechless medalmerit Learn More Undo "There is not much data available on this device in India, and hence, it will be difficult to assess its merit over conventional reconstruction," said an orthopaedic surgeon from a Kolkata hospital. Karmakar said the bio-absorbable material in the device does not cause allergic reaction as it mimics collagen tissues, which get absorbed and convert into ligament. "The biggest disadvantage is the cost. In the past three to four months, I have used it on around seven patients, including athletes in Odisha," said arthroscopy surgeon Sarthak Patnaik, founder of Sports Science of India, the first sports medicine centre in Odisha.
