What Do People Who Live Past 110 Have in Common? What Research Shows
People who reach 110 or beyond — known as supercentenarians — tend to share traits such as leanness, disease-free aging and steady daily routines, according to Spanish cardiologist Manuel de la Peña. He attributes 75% of longevity to lifestyle and only 25% to genes, but a 2026 genetics study puts heredity's share closer to 50–55%, showing researchers still disagree on how much is nature versus habit.
How Hospital Sink Drains Become Reservoirs for Resistant Bacteria
Hospital hand-washing sinks can turn into long-term reservoirs for antibiotic-resistant bacteria that colonize drain pipes and splash onto nearby counters, according to peer-reviewed research and hospital outbreak reports. Documented outbreaks in Toronto and Tokyo show that cleaning or replacing a sink alone did not stop transmission; cases ended only after facilities combined sink redesign, stricter cleaning schedules and changes to staff hand-hygiene routines.
New Study Links Disrupted Body Clock to a Distinct Depression Subtype
A study published in the British Journal of Psychiatry on 20 October 2026 found that roughly a quarter of people with severe, recurrent or persistent depression show a pattern researchers call "circadian depression," tied to disrupted sleep-wake rhythms rather than mood alone. The University of Sydney-led team says this subtype responds less to standard antidepressants and more to treatments that target the body clock, such as light therapy and melatonin.
FDA Classifies Recall of Over 4.3 Million Toothpaste Tubes, Including Kids' Brands
The FDA on October 19, 2026 classified a voluntary recall of more than 4.3 million tubes of toothpaste sold under the Brush Buddies, evo and ARU brands. The recall, covering children's products such as Barbie, Hot Wheels, My Little Pony and Crayola Silly Scents toothpaste, stems from manufacturing practice deviations; no illnesses have been reported.
Sleep Hygiene Guide: Evidence-Based Steps to Improve Sleep Quality and Duration
Improving sleep quality mainly comes down to a consistent sleep-wake schedule, a cool and dark bedroom, limiting caffeine and alcohol, and reducing screen use before bed, according to the US CDC and the UK's NHS. Adults aged 18 to 60 should get seven or more hours a night, says a 2015 consensus statement from the American Academy of Sleep Medicine and the Sleep Research Society.
Cholesterol and Diet: Foods to Limit and Changes That Support Heart Health
High cholesterol usually causes no symptoms, so health bodies rely on blood tests and dietary changes rather than taste or feel. The main step is cutting saturated fat — found in fatty meat, butter, cream, cheese and palm or coconut oil — and replacing it with unsaturated fats, fibre, oily fish and more exercise.
How coffee changes gut bacteria and may affect mood, study finds
A 2026 University College Cork trial found that both caffeinated and decaffeinated coffee altered gut bacteria and were linked to lower stress, depression and impulsivity scores. Caffeine alone improved attention and reduced anxiety, while decaf alone improved memory and learning, according to the study published in Nature Communications.
Why Flu Season Is Starting Early in 2026: The Mutation Behind the Surge
US flu activity has risen earlier than usual in autumn 2026, with the West Coast reporting the highest levels, according to CDC surveillance data. Health officials and researchers link the early start partly to a mutated H3N2 strain known as subclade K, while national vaccination coverage remains below 44%.
Tea and Heart Health: What a New 486,000-Person Study Found About Temperature
A large observational study of nearly 486,000 Chinese adults found that regular tea drinkers had an 11% lower risk of vascular disease than non-drinkers — but drinking tea "burning hot" was linked to a 16% higher risk. Researchers say the temperature at which tea is drunk may matter as much as how often it is drunk.
Common Cold vs. Flu: How to Tell the Difference
The clearest clue is speed of onset: flu symptoms hit suddenly and include fever, chills and body aches, while a cold builds gradually over a day or two and centers on a runny or stuffy nose. Health authorities say the two illnesses share many symptoms, so a lab test is the only way to confirm which virus is responsible.
What Is GLP-1? How the Gut Hormone That Signals Fullness Works
GLP-1 is a hormone released by the small intestine after eating that slows digestion, raises insulin, and signals the brain that the body has had enough food. Rising public interest in weight-loss drugs that mimic this hormone has put the spotlight on how the natural system behind it actually functions, and what dietary factors are linked to it.
Kennedy's Vaccine Injury Clinic and Compensation Overhaul Draw Scientific, Public Pushback
Health Secretary Robert F. Kennedy Jr. opened a new vaccine injury clinic at the National Institutes of Health on October 5, 2026, and has moved to reshape federal vaccine-safety oversight, including replacing advisory panel members. The NIH's own governing board and several public polls have since pushed back, warning the effort risks politicizing science and undermining trust in vaccines.
Why Hair Shedding Increases in Autumn and How Summer UV Exposure Is Involved
Hair shedding often rises in autumn mainly because hair follicles damaged by summer sun and sweat stop growing weeks earlier, then fall out once the scalp starts to recover. Japanese dermatologists and a 2026 clinic survey link this to poor scalp sun protection, while some researchers note the seasonal pattern itself is only partly confirmed by science.
Heat Stroke vs. Heat Exhaustion: Warning Signs and How to Respond
Heat exhaustion causes heavy sweating, nausea and weakness but usually resolves with cooling and fluids within about 30 minutes. Heat stroke is a medical emergency marked by a very high body temperature, hot skin and confusion, and it requires calling emergency services immediately, according to the US CDC, the UK's NHS and the World Health Organization.
How Vaccines Work: The Science Behind Immunization Explained
Vaccines work by showing the immune system a harmless piece or weakened version of a pathogen, so the body builds antibodies and memory cells before it ever meets the real infection. When exposed later, a vaccinated immune system reacts faster and more effectively, which is why most vaccines require more than one dose. This same principle underlies all vaccine types, from decades-old live-attenuated shots to newer mRNA vaccines.
Building Resilience and Mental Toughness: A Practical, Evidence-Based Guide
Resilience is the ability to adapt to and recover from stress, while mental toughness describes staying confident, committed and in control under pressure. Harvard Medical School, the NHS, the US National Institute of Mental Health and sport-psychology researchers outline concrete, sourced steps for strengthening both, from reframing stressful thoughts to using the "4Cs" framework.
How the Human Immune System Works: Innate Immunity, Adaptive Immunity and Memory
The immune system defends the body in two linked stages: an innate response that acts immediately but non-specifically, and an adaptive response that is slower but targets a specific pathogen and leaves behind memory cells. That memory is also the biological basis of how vaccines protect people, according to the National Institutes of Health and the World Health Organization.
First Aid Basics: The Core Emergency Skills Everyone Should Know
First aid basics cover five situations: an unresponsive but breathing person, someone who has stopped breathing, severe bleeding, choking, and burns. Health bodies including St John Ambulance (UK) and the World Health Organization say bystanders acting in the first minutes of an emergency can affect the outcome before professional help arrives. This guide summarizes the step-by-step actions recommended by these organizations — it is not a substitute for a certified first aid course.
How to Maintain a Healthy Weight: A WHO and CDC-Based Nutrition and Fitness Guide
Maintaining a healthy weight relies on balancing calories eaten with calories burned through regular physical activity, according to the World Health Organization and the U.S. Centers for Disease Control and Prevention. Both agencies recommend at least 150 minutes of moderate-intensity activity a week combined with a diet built around fruit, vegetables, whole grains and limited sugar, salt and saturated fat.
How to Recognize Depression and Cope With It: A Practical Guide
Depression is defined by a persistently low or empty mood, or loss of interest in activities, lasting most of the day nearly every day for at least two weeks, according to the World Health Organization and the U.S. National Institute of Mental Health (NIMH). This guide lists the symptoms health agencies use to identify it, who is most affected, evidence-based coping steps, and where to get crisis help if needed.
Nutrition Myths vs. Facts: What Major Health Bodies Actually Say
Many widely repeated claims about carbs, eggs, coconut oil and vitamin C are not supported by current evidence from bodies such as the World Health Organization and Harvard Health. This explainer compares common nutrition myths with the facts, using WHO's official dietary targets and findings summarised by Harvard Health and the European Food Information Council (EUFIC).
How to Start Journaling for Mental Health: A Beginner's Guide
Journaling is a low-cost self-help practice — writing freely about feelings, gratitude or daily mood — that health resources link to lower anxiety, better mood and improved coping with stress. Evidence reviewed by medical and university wellness sources shows modest but real benefits, with experts stressing it works best alongside, not instead of, professional mental-health care.
Why a Lactation-Stopping Drug Is Being Studied to Cut Breast Cancer Risk
A new study links cabergoline, a drug already used to stop breast milk production, to a lower chance of developing breast cancer after childbirth. Researchers who analyzed health records of more than 150,000 women in Spain and Norway, plus mouse experiments, say the drug speeds up a natural tissue-clearing process in the breast after weaning. Human clinical trials, not yet approved for cancer prevention use, are now being organized.
How to Sleep Better: Science-Based Strategies to Overcome Insomnia
Cognitive behavioral therapy for insomnia (CBT-I), not sleeping pills, is the first-line treatment the American College of Physicians recommends for chronic insomnia in adults. It combines five evidence-based techniques — stimulus control, sleep restriction, cognitive restructuring, relaxation training and sleep hygiene — and the Sleep Foundation reports 70-80% of patients with primary insomnia improve, usually within six to eight sessions.
Lightning Safety: How to Protect Yourself Indoors and Outdoors During a Storm
The safest response to thunder is to get into a substantial building or a hard-topped vehicle immediately — there is no fully safe place outdoors. Avoid water, corded electronics, open ground, isolated trees, and metal; if someone is struck, call emergency services and start CPR if needed, since it is safe to touch a lightning victim.
First Aid Basics: How to Recognise and Respond to Medical Emergencies
Four emergencies — cardiac arrest, choking, severe bleeding and stroke — follow the same pattern: check the person, call emergency services, then act while help is on the way. This guide sets out the step-by-step bystander actions published by the British Red Cross and St John Ambulance for each situation.
How the Immune System Works to Protect the Body From Disease
The immune system defends the body through two linked systems: innate immunity, which reacts immediately but non-specifically, and adaptive immunity, which takes days to mount a tailored response but can "remember" a pathogen for years. Physical barriers such as skin and mucous membranes, organs including the bone marrow, thymus, spleen and lymph nodes, and cells such as phagocytes, T-cells and B-cells all work together, according to U.S. health agencies and the Cleveland Clinic.
Amazon Recalls Over 112,000 Bottles of Acetaminophen Over Discolored Pills
Aurobindo Pharma USA has voluntarily recalled 112,932 bottles of Amazon Basic Care Extra Strength Acetaminophen sold nationwide through Amazon after customers reported discolored caplets. The recall, covering seven lot numbers across 200-, 500- and 1,000-count bottles, began September 18, 2026, and the FDA has not yet assigned it a risk classification.
Starting to Exercise: A Beginner's Guide to Weekly Activity Guidelines
Major health authorities, including the U.S. CDC and the World Health Organization, recommend adults get at least 150 minutes of moderate-intensity aerobic activity a week; the CDC also recommends muscle-strengthening work on two or more days. For beginners, guidance from the CDC and the Mayo Clinic points to starting slowly, warming up before and cooling down after each session, and increasing activity by roughly 10% a week rather than all at once.
Hormonal IUD for Endometriosis: How It Works and How Well It Treats Symptoms
A hormonal intrauterine device (IUD) releases the progestin levonorgestrel directly into the uterus, which thins the uterine lining and can reduce endometriosis-related pain and bleeding. Clinical guidelines list it as a second-line hormonal option, and studies report pain scores falling significantly within a year, with benefits lasting up to a decade in some patients, though the device is not a cure.
