An umbrella review and meta-meta-analysis published online in the British Journal of Sports Medicine (February 2026) found that exercise, particularly aerobic activity, significantly reduces symptoms of depression and anxiety across age groups. Researchers led by James Cook University searched pooled analyses of randomized trials up to July 2025, incorporating tens of thousands of participants (roughly 57,930 in depression analyses and 19,368 in anxiety analyses drawn from up to about 800 component trials). Overall effect sizes were medium for depression (SMD ~ -0.61) and small-to-medium for anxiety (SMD ~ -0.47). Aerobic, group-based and supervised formats produced the largest antidepressant effects, while shorter (up to eight weeks), lower-intensity programmes were most associated with anxiety reductions. The strongest benefits were seen in young adults (18–30) and postnatal women. The authors say exercise outcomes compare favourably with pharmacological (SMD ~ -0.36) and psychotherapeutic (SMD ~ -0.34) interventions, and recommend tailored, prescribed exercise as an accessible, cost-effective first-line option. They also note heterogeneity in study quality and intensity definitions and caution that findings are most robust for mild or subclinical cases.

A Penn State-led study published in the Journal of Nutrition found diets high in fat — including a ketogenic regimen — caused greater metabolic and liver damage than high-carbohydrate diets in mice. Over 16 weeks researchers fed mice one of four diets (high-carbohydrate, high-fat, ketogenic or a whole-grain-rich control) while keeping protein at 18% of calories. The high-fat (40% fat) and ketogenic (81% fat, 1% carbohydrate) groups showed pronounced weight gain (weights doubled), impaired glucose tolerance, early liver injury (evident within two weeks), increased systemic inflammation, higher triglycerides and fat deposits in the liver, plus expression changes linked to scarring. Mice on the whole-grain chow (57.5% carbohydrates, 13.5% fat) had the healthiest markers. Diet fats were largely saturated; carbohydrates in experimental diets were mainly refined. Authors noted fiber supplementation could mitigate harm in some settings and cautioned that human and mouse metabolisms differ, underscoring need for supervised dietary changes.

Australia’s federal and state food ministers have moved to require the front-of-pack Health Star Rating (HSR) on all packaged food, after officials concluded the voluntary scheme failed to reach its uptake target. Governments indicated on Feb. 10–11, 2026, that they will ask the food regulator to develop a formal proposal for mandatory application, with a final decision expected in about 12 months. The voluntary target — 70% of packaged products labelled by November 2025 — was not met, with take-up around 37% according to Assistant Health Minister Rebecca White. Public health experts want the HSR algorithm revised to account for ultra-processed foods and close perceived loopholes that allow reformulated products to achieve higher star ratings despite containing additives. The National Health and Medical Research Council is reviewing evidence on ultra-processed foods. Industry groups argue processing improves safety, affordability and access, and say nutrient-based scoring already considers positives and negatives. If adopted, mandatory HSRs would be the first major update to national labelling guidance in 13 years and would change how products are marketed and presented on supermarket shelves nationwide.

More than 94 million people worldwide need cataract surgery but roughly half lack access to treatment, the World Health Organization said on Feb. 11, 2026, as it released new guidance on expanding quality cataract services. Cataract remains the leading cause of blindness and a major cause of vision impairment; surgery is a short, cost-effective procedure (about 15 minutes; intraocular lens cost can be under US$100). WHO and a new Lancet analysis—using Rapid Assessment of Avoidable Blindness and other population surveys across 68 countries with modelled trends to 2030—show large unmet need, worst in Africa where three in four people remain untreated. The WHO-backed modelling projects cataract surgical coverage will rise by only about 8.4% this decade, far short of the 30 percentage-point eCSC target set by member states for 2030. Women have consistently lower access than men, and in some settings, notably Kenya, current rates mean many patients will die with cataract-related blindness. WHO urges integration of eye care into primary health services, investment in equipment and financing, and scale-up of standardised surgeon training and workforce distribution.

A top U.S. health official urged Americans to get measles vaccinations as outbreaks spread across multiple states, raising alarms that the country could lose its measles-elimination status. On Feb. 8, 2026, Centers for Medicare & Medicaid Services administrator Dr. Mehmet Oz told CNN viewers, “Take the vaccine, please,” and said Medicare and Medicaid will continue to cover the shot. South Carolina is facing the largest outbreak in years, with roughly 920 confirmed cases, and clusters have also been reported along the Utah–Arizona border and elsewhere. The calls for vaccination come amid broader strains on trust in U.S. vaccine policy: an Annenberg survey (Nov. 17–Dec. 1, 2025) found perceptions of vaccine safety slipping — 83% view MMR as safe, 80% the flu vaccine and 65% COVID-19 vaccines — and a KFF poll shows public trust in the CDC has fallen dramatically. Since 2025 the Health and Human Services department has altered federal guidance, moving several childhood vaccines to shared clinical decision-making and removing key advisory committee members, prompting major medical groups to push back. On Feb. 10, 2026 the American Medical Association and the Vaccine Integrity Project said they would run independent evidence reviews for the 2026–27 respiratory season to restore confidence.

A coroner has found that the death of 13-year-old Chloe Longster at Kettering General Hospital in November 2022 was "contributed to by neglect" after staff reportedly delayed pain relief and antibiotics and dismissed the girl as a "diva teen." Chloe, from Market Harborough, died of pneumonia and sepsis about 18 hours after admission. An inquest heard multiple missed opportunities to recognise her deterioration, including a displaced nasal cannula and errors in patient identification. Following a CQC investigation, the Trust received a fixed-penalty notice of £1,250 for failing its duty of candour; the trust has paid the fine and a banner will appear on the regulator's site for three months. Chloe’s family says statutory time limits and evidential thresholds have closed off further prosecution and left unresolved questions about accountability and transparency in the case.

In early February 2026 several British media outlets reported outrage after multiple NHS trusts advertised specialist roles to support families in close-relative (often first-cousin) marriages. Manchester University NHS Foundation Trust posted a fixed-term neonatal/genetic counselling role seeking an Urdu-speaking nurse to help couples “make informed choices in a culturally sensitive” way; similar posts were listed in Frimley, Bedfordshire and Bradford. The controversy intensified after a government-funded monitoring body, the National Child Mortality Database, warned staff it is “unacceptable” to discourage cousin marriage in a blanket way — a finding described in coverage as not being formal NHS England guidance. Critics and some MPs pointed to research and expert commentary that children of first-cousin parents face elevated risks of recessive genetic disorders (commonly cited as up to about three times higher). Campaigners who are survivors or carers of affected families denounced the NHS material as dangerously permissive, while ministers have said NHS England is funding additional genomic and neonatal capacity through pilot projects. The adverts and guidance have provoked debate over public health messaging, cultural sensitivity and the allocation of NHS resources.

Washington, D.C., health officials have warned that multiple confirmed measles cases visited several city locations while contagious, potentially exposing thousands who attended the National March for Life rally on Jan. 23. DC Health said exposures occurred between Jan. 21 and Feb. 2 and listed specific sites including the National Mall (March for Life rally and concert), the Basilica of the National Shrine of the Immaculate Conception (Jan. 21), Catholic University of America (Jan. 24–25), Ronald Reagan Washington National Airport (Jan. 26), Washington Metro lines (Jan. 26–27), Union Station and Amtrak concourse (Jan. 27), and Children’s National Hospital emergency department (Feb. 2). Officials urged anyone potentially exposed to check vaccination status, monitor for symptoms for 21 days and contact health providers or DC Health for guidance. The warning comes amid a large U.S. resurgence of measles this year — federal authorities have reported several hundred confirmed cases and major outbreaks, notably in South Carolina and Texas — driven largely by unvaccinated populations. Two MMR doses are about 97% effective; public-health authorities emphasize vaccination, isolation of suspected cases and quarantine of contacts to limit further spread.

The Trump administration this week moved to terminate roughly $600 million in public health grants directed to four Democratic-led U.S. states — California, Colorado, Illinois and Minnesota — part of a broader push that officials instructed agencies to claw back more than $1.5 billion in federal grants across the Centers for Disease Control and Prevention and the Department of Transportation. Targeted programs include HIV and sexually transmitted infection surveillance and prevention projects (for example a $1.1 million Los Angeles County behavioral surveillance project and community prevention funds for the Los Angeles LGBT Center), research grants (including a $7.2 million American Medical Association award and a $5.2 million Chicago hospital project), and transportation and climate adaptation grants such as funding for electric vehicle chargers and translating commercial driver’s license tests. Administration officials say the grants “no longer reflect” agency priorities and have cited concerns about DEI and gender-affirming care; critics say the moves are politically motivated. States and affected organizations said they had not received formal notices and plan legal challenges; courts previously blocked similar funding restrictions. Public health experts warn the terminations could weaken outbreak detection and services for vulnerable populations.

The UK Health Security Agency (UKHSA) and the Medicines and Healthcare products Regulatory Agency (MHRA) have issued renewed warnings about non-sterile alcohol-free cleansing wipes after an outbreak of Burkholderia stabilis linked to four products. Authorities say 59 confirmed cases in the United Kingdom have been connected to the contaminated wipes between January 2018 and 3 February 2026, including several serious infections and one death. The items identified are ValueAid Alcohol Free Cleansing Wipes, Microsafe Moist Wipe Alcohol Free, Steroplast Sterowipe Alcohol Free Cleansing Wipes and Reliwipe Alcohol Free Cleansing Wipes; testing found the first three carried the outbreak strain while Reliwipe contained an unrelated Burkholderia strain. The products were withdrawn from sale after MHRA notices, but regulators warn they may still be present in household first-aid kits and clinical settings. No person-to-person transmission has been recorded. UKHSA and MHRA advise discarding affected wipes in household rubbish, never using non-sterile alcohol-free wipes on broken skin or around intravenous lines, and that only wipes labelled sterile be used for wound care. Healthcare providers are instructed to check supplies and patients with signs of infection should seek urgent advice.

On Feb. 9 the New York Times editorial board — which has long supported marijuana legalization — published a major reassessment, saying the loosening of U.S. marijuana policies has produced worse outcomes than expected and calling for stronger regulation. The board cited survey data showing roughly 18 million Americans use marijuana almost daily, up from about 6 million in 2012 and under 1 million in 1992. It highlighted rising health harms including nearly 2.8 million annual cases of cannabinoid hyperemesis syndrome, more hospitalizations for marijuana-linked paranoia and chronic psychotic disorders, and injuries tied to impaired driving. The editorial rejects a return to broad criminalization — noting the disproportionate harms of past drug enforcement on Black, Latino and poor communities — but argues the current hands-off, commercialized approach has gone too far and urges lawmakers to adopt stricter controls on availability, potency, advertising and other aspects of the legal market. The piece follows federal easing of restrictions in December and comes as states consider ballot measures and regulatory changes.

Countryfile presenter Julia Bradbury, 55, provided a health update on Feb. 10, 2026, posting video from a medical chair showing her receiving an ‘immune‑boosting’ IV containing vitamin C, minerals and amino acids. Bradbury, who was diagnosed with breast cancer in 2021 and had a mastectomy to remove a 6cm tumour, is now in remission and fronting the ITV series Wonders of the Frozen South. She has spoken tearfully in recent days about fearing for her life after the diagnosis and about reaching emotional milestones while filming in Antarctica. Bradbury says her cancer prompted major lifestyle changes — cutting out sugar, largely stopping alcohol, prioritising sleep, meditation and more time outdoors — and has faced some social media backlash for emphasising those choices. Media coverage of Countryfile has also revisited other presenters’ health struggles, including Matt Baker’s ongoing back injury, John Craven’s vision and hearing issues, and Charlotte Smith’s past lung condition, highlighting the series’ long history of presenters confronting serious medical problems.

Senators Elizabeth Warren (D-Mass.) and Josh Hawley (R-Mo.) on Feb. 10 introduced bipartisan legislation aimed at dismantling vertically integrated healthcare conglomerates they say drive up costs and stifle competition. The bill would bar a parent company from owning both a medical provider or management services organization and a pharmacy benefit manager (PBM) or insurer, and would also restrict wholesalers from owning provider organizations. It targets firms such as UnitedHealthcare (Optum), CVS Health (Caremark/Aetna) and other companies whose PBMs process the majority of U.S. prescriptions. Supporters call the measure a “Glass-Steagall” for health care and would empower the FTC, HHS and DOJ to enforce penalties and bring suits against noncompliant firms. The move follows bipartisan scrutiny of PBMs, recent provisions in a federal appropriations package and White House executive actions on drug prices. Industry leaders have pushed back, saying integrated models benefit consumers. The bill’s unveiling ahead of U.S. midterm elections highlights political pressure to address affordability and market concentration in the health sector.

UK newspapers on Feb. 10, 2026 highlighted evidence that smoking may accelerate hair thinning and premature greying. Hair specialists and a UK clinic cited research showing men who smoke are about 1.8 times more likely to have male pattern baldness (Journal of Cosmetic Dermatology) and smokers were 2.5 times more likely to develop early grey hair (Indian Dermatology Online Journal). Experts say tobacco use can impair circulation and reduce oxygen and nutrient delivery to hair follicles, disrupting the hair growth cycle and contributing to increased shedding, dryness, breakage and earlier greying. UK Hair Transplants urged quitting smoking as a tangible way to protect scalp health and slow thinning, while advising those with sudden or patchy loss to consult a GP to rule out other causes. The coverage frames hair effects as another potential short- and long-term harm of smoking, adding cosmetic concerns to established cancer, respiratory and cardiovascular risks.

Co-op has recalled its Irresistible Triple Cook Thick Cut Chunky Chips after a packaging error led 360g packs labelled as chips to be filled with Dauphinoise potatoes that contain milk not declared on the label. The affected packs carry a use-by date of 14 February 2026. The Food Standards Agency issued an allergy alert and Co-op has notified relevant allergy support organisations while displaying point-of-sale notices in stores. Customers with a milk allergy or intolerance are advised not to eat the product and to return affected packs to any Co-op for a full refund; online purchasers may obtain refunds by calling 0330 041 7737. For further enquiries Co-op has provided a customer service line on 0800 0686 727. The retailer apologised for the inconvenience. Health bodies warn milk allergy can cause symptoms ranging from mild rash and vomiting to severe anaphylaxis, and anyone concerned should seek medical advice.

British consumer watchdog Which? has uncovered prescription-only melatonin products being advertised and sold on major online marketplaces, including AliExpress, Amazon, eBay, Etsy, Superdrug Marketplace and Temu, in an investigation covering October 2025 to January 2026. Which? found products with doses far above typical NHS starting guidance — often listed at 10mg and, in one case, a product claiming 30mg — and noted sellers hiding melatonin in ingredient lists or disguising names (eg. 'melat onin') to evade detection. The watchdog flagged items marketed as 'night-time fat burners', patches and teas that contained melatonin or listed it only in descriptions. Platforms said they removed flagged listings and were taking enforcement action; Superdrug said it has approached the Medicines and Healthcare products Regulatory Agency (MHRA) for clarity on topical products containing melatonin. In the UK melatonin is a prescription medicine because it can interact with common drugs such as antidepressants and hormonal contraception and cause side effects including dizziness and mood changes. Which? warned that unchecked online sales pose health risks and called for stronger oversight and enforcement.

Manchester University NHS Foundation Trust this week advertised a fixed-term neonatal nurse role to provide culturally sensitive reproductive and genetic support to families practising close-relative (including first-cousin) marriage. The full-time post, now closed to applications, sought a candidate fluent in Urdu and offered a salary of £37,338–£44,962 for a 12-month contract. NHS guidance cited by media this year acknowledges increased genetic risks in some cousin unions but stresses most such couples do not have affected children and recommends balancing risks with social and economic considerations. Similar posts have been advertised elsewhere in England, including Frimley, Bradford and Bedfordshire, as trusts seek to improve engagement with genetic services for affected communities. The recruitment prompted criticism from campaigners who say the practice carries serious child-health and social-care costs; bereaved relatives and activists have urged stronger prevention and education. The story has reignited debate on how the NHS should combine culturally sensitive care with public-health messaging on inherited disorders.

Actress Christina Applegate has launched an online community called Next in MS for people living with multiple sclerosis, the star announced on Feb. 9, 2026. Applegate, who revealed her MS diagnosis in 2021 and co-hosts the MeSsy podcast with fellow MS patient Jamie-Lynn Sigler, said the site is meant to let users share “the good, the bad, the ugly, the in-betweens, the diapers” of life with MS. The initiative is being promoted with a Super Bowl advertisement in which Applegate bluntly described the disease as “zero stars,” and she said she will contribute her own experiences and resources. The platform is launched in partnership with pharmaceutical company TG Therapeutics. Applegate’s new memoir, You With the Sad Eyes, is due March 3, 2026. She framed the project as a way to reach more members of the MS community, foster open conversation about challenges and hope, and provide peer support and information alongside lived experiences.

Researchers analysed more than 600,000 traditional Medicare hospitalisations around the suspension and reinstatement of the Medicare 'three‑day rule' and found the policy’s return on May 12, 2023 increased the share of stays lasting at least three nights without improving outcomes or lowering spending. Using a regression‑discontinuity design comparing hospitalisations in the 28 days before and after reinstatement, the JAMA Internal Medicine study (published Feb. 9, 2026) found a 1.13 percentage‑point overall rise (60.4% to 62.0%) in stays of three or more nights and a 5.57‑point rise among patients discharged to skilled nursing facilities. There were no significant changes in SNF use, total SNF days, 30‑day readmissions, 30‑day mortality or Medicare spending. Subgroups with dementia and hip fractures saw larger increases. Authors say the rule appears to have driven longer inpatient stays—adding at least 2,000 hospital days in the first month—and recommend reconsideration of the policy while noting limits to generalisability and potential confounding.

The US Centers for Disease Control and Prevention has issued Level 2 travel advisories for the Seychelles and Suriname amid resurgent chikungunya transmission, urging travellers to “practice advanced precautions.” The mosquito‑borne alphavirus, spread by Aedes species that also carry dengue and Zika, causes sudden high fever, rash, headache and often severe joint pain that can persist for months or years. Health agencies report a marked upsurge in chikungunya since 2025 with hundreds of thousands of infections and several hundred deaths recorded across multiple countries; hotspots in the Americas and outbreaks in China last year have prompted repeated warnings. The CDC says higher‑risk groups include older adults, people with underlying heart or metabolic disease, newborns and pregnant people; it advises insect repellent, protective clothing and screened or air‑conditioned accommodation. A chikungunya vaccine is now available and recommended for travellers to affected areas, though pregnant people are generally advised to defer vaccination until after delivery and to reconsider travel near term. US officials have noted occasional locally acquired cases in recent years, underscoring the risk of local transmission where Aedes mosquitoes are present.
