The winter season compels us to sit at one place, under the blanket, at the ease of warmth. But aren't we all aware of the dangers of a sedentary lifestyle? And when it is winter, it makes it more so stagnant. Not just that, but now a new study from the University of Iowa says that being a couch potato could lead to 19 chronic conditions. Among the 19 chronic conditions, obesity, diabetes, depression and heart diseases also made it to the list.
Research shows that among many diseases, increased blood pressure, high blood sugar, excess body fat around the waist, unhealthy cholesterol levels that leads to metabolic syndrome, cardiovascular disease and cancer are also there. This is why any extended sitting whether at desk, behind the wheel or the screen can be harmful.
The team of researchers from various departments at the University of Iowa conducted a detailed study where they analyzed records from over 40,000 patients at a major Midwestern hospital system. In the records, they looked at the extensive physical inactivity of these patients and how it impacted their overall health.
The study and the detailed analysis is published in the journal Preventing Chronic Disease and studies.
As part of conducting the study, a 30-second exercise survey was conducted. Then, patients were also asked two questions: how many days per week they engaged in moderate to vigorous exercise and for how many minutes per session? On the basis of response, the patients were categorized into three groups:
As per Lucas Carr, associate professor in the Department of Health and Human Physiology and study's corresponding author, "This two-question survey typically takes fewer than 30 seconds for a patient to complete so it does not interfere with their visit. But it can tell us a whole lot about that patient's overall health."
The study got 7,261 responses, and it found that around 60% of them met the recommended guidelines for exercising. These people met the 150 minutes or more minutes of moderate exercise per week. However, almost 36% exercised less than 150 minutes per week and 4% reported no physical activity.
The study also found that people experienced lower rates of depression. 15% of people who exercise for 150 minutes or more, or at least for some amount of time could experience depression, as compared to 26% of those who are inactive. Similarly, for obesity, the numbers are 12% versus 21% for obesity, 20% versus 35% for hypertension and the similar trend was seen in other diseases, and markers of good health, including lower resting pulse rates, and cholesterol profiles.
Patients with no physical activity carried a median of 2.16 chronic conditions, this number was 1.49 conditions in insufficiently active patients and dropped to 1.17 in active patients.

Ever wondered how your body generates antibodies in the face of a virus attack? A new study by French researchers showed that our age, biological sex, and human genetic factors can determine our immunity levels.
The human body, when exposed to a virus, defends itself by producing molecules called antibodies. Their main function is to identify pathogens and kill them.
Scientists from the Institut Pasteur, the CNRS, and the Collège de France noted that these factors not only boost the quantity of antibodies produced in the body but also determine the specific viral regions to target.
The February 2026 study, published in the journal Nature Immunology, can pave the way for the development of personalized treatments, especially for individuals who are most vulnerable to infection.
"This study provides a detailed, integrated view of how age, sex, and human genetics shape the antibody response," said Lluis Quintana-Murci, Head of the Human Evolutionary Genetics laboratory at the Institut Pasteur.
"It shows that these factors even determine which specific regions of a given virus are targeted by antibodies, with important implications for vaccine and therapeutic design," Quintana-Murci added.
How Age And Sex Influence Immunity
The findings revealed that individuals produce antibodies that target different parts of the virus when attacked by the same virus. Age was identified as the dominant factor influencing antibody production. The team noted that more than half of the antibody repertoire varies depending on age.
Further, some antibodies were found to increase with age, while others decreased. This was seen particularly in the case of influenza H1N1 and H3N2 viruses.
In young adults, the antibodies mainly targeted a part of the viral surface protein known as hemagglutinin (HA), which evolves rapidly. In older individuals, it focused on a more stable region of the same protein known as the stalk domain.
Women were also found to produce more antibodies against HA. On the other hand, men tended to target other viral proteins (NP and M1), despite comparable vaccination rates between the two sexes.
How Human Genetics Shape Antibody Production
The team identified mutations in genomic regions known to encode the immunoglobulin repertoire. These variants determine which genes are used to produce antibodies.
Using an African cohort, the study revealed population disparities in terms of the molecular targets of their antibody repertoires.
In the case of Epstein-Barr virus (EBV), antibodies were found to recognize different viral proteins depending on the geographical and epidemiological context.
This difference can be explained by the level of exposure -- Africans are more exposed to a particular strain of EBV in which the protein EBNA-4 is the primary antibody target.
How Was The Study Conducted?
The research is based on data from the Milieu Intérieur cohort, launched 15 years ago to study variations in the immune response in 1,000 healthy individuals.
Using an innovative sequencing technology, the scientists analyzed blood plasma samples to measure antibody responses against more than 90,000 fragments of viral proteins, covering a large number of viruses responsible for infections such as influenza, respiratory infections, gastroenteritis, and herpesvirus infections.
Epstein Files: After the Department of Justice (DOJ) released more files on the late sex offender and financer Jeffrey Epstein, previously unseen photographs, including medical details and a detailed timeline of his final weeks in custody have resurfaced. All of this new information has added fresh scrutiny to the case.
A 23-page long document, labelled unclassified titled Jefferey Epstein Death Investigation was prepared by the New York field officer of the FBI. The material has been examined by BBC Verify and was reported to contain close-up images of Epstein's body, notes from his post-mortem examination and psychological observations that were recorded shortly before his death in August 2019.
As per BBC, the photographs included detailed views of injuries to Epstein's neck and show medics attempting to resuscitation after he was found unresponsive in his jail cell. As per the timestamps visible in the files, the images were taken at 06:40 local time on 10 August 2019, almost 16 minutes after a prison staff discovered him.
As per the DOJ's Office of the Inspector General's review report released in June 2023, on August 10 at 6.30am, two SHU staff on duty CO Tova Noel and Material Handler Michael Thomas delivered breakfast to inmates, when Noel was delivering breakfast from the food slot of the door to Epstein's SHU tier, there was no response. Thomas unlocked the door and saw Epstein hanged. The review report mentions that he immediately "yelled for Noel to get help and call for a medical emergency". According to Noel, within seconds of Thomas calling out for the clutter she hit the body alarm, which is a button on an MCC staff member's radio that is used to signal distress or an emergency. Noel also recalled Thomas saying, "Breathe, Epstein, breathe." As per Noel, when she saw Epstein, he looked "blue and did not have a shirt or anything around his neck".

As per Thomas, when he entered Epstein's cell, he had an orange string, from a sheet or a shirt, around his neck that was tied t the top portion of the bunkbed. The review report notes: "Epstein was suspended from the top bunk in a near-seated position, with his buttocks approximately 1 inch to 1 inch and a half off the floor." As per Thomas, he immediately ripped the orange string from the bunkbed and Epstein's buttocks dropped to the ground, and lowered him to begin chest compressions until staff arrived.
As per the BBC reports, the location is not explicitly stated in the documents, but records indicate Epstein had already been transported to hospital at 06:39, where he was later pronounced dead, suggesting the images were likely taken there.
Some of the photographs show a tag attached to his hand with his name and date of death. In several images, however, his first name appears misspelled as “Jeffery”.

The investigation file incorporates sections of an 89-page post-mortem report compiled jointly by the Department of Justice and New York’s Office of Chief Medical Examiner. Among the medical findings were scans documenting fractures in the thyroid cartilage of Epstein’s neck.
BBC Verify said it conducted reverse image searches and “could not find earlier versions” of the photos online before their recent release, indicating they had not previously circulated publicly.
The report also reconstructs Epstein’s detention inside the Metropolitan Correctional Center from his arrest on 6 July 2019 on federal sex-trafficking charges to his death five weeks later.
According to the timeline, Epstein was placed on suicide watch after a 23 July incident in which he was found injured in his cell. At the time, he claimed his cellmate — Nicholas Tartaglione — had attacked him.

The following day, during a psychological assessment, Epstein denied wanting to harm himself. BBC reported the document states he said he had “no interest in killing myself” and that it “would be crazy” to do so. Two days later, notes record him saying he was “too vested in my case” and wanted to return to his life.
Despite that, prison officials had recommended he not be housed alone and that guards perform checks every 30 minutes, including unannounced rounds.
The newly released records outline several security lapses the night before Epstein died.
His cellmate had been transferred out the previous day, leaving him alone. Prison logs show guards failed to conduct scheduled checks at 03:00 and 05:00, and the unit’s camera system was not functioning. Staff later discovered his body during a morning inspection.
The files also include two versions of the same FBI report: a full 23-page unredacted copy and a shorter 17-page redacted version that omits the psychological report and detention timeline. The reason for the dual publication has not been explained.
The Department of Justice has been contacted for comment, while the FBI declined to respond, reported BBC.
The release of the material does not change the official ruling of suicide, but its level of detail, particularly the photographs, mental-health notes and security failures — is likely to reignite debate over the circumstances surrounding Epstein’s death.

As per the American Psychological Association (APA), only 58.5 per cent of US teens always or usually receive the social and emotional support they need, as per the report by the US Centers for Disease Control and Prevention (CDC).
Another National Institutes of Health (NIH, US) report notes that the most mental health disorders among children ages 3 to 17 in 2016 to 2019 were attention deficit disorder (9.8%, approximately 6 million), anxiety (9.4%, approximately 5.8 million), behavior problems (8.9%, approximately 5.5 million), and depression (4.4%, approximately 2.7 million). For adolescents, depression is concerning because 15.1% of adolescents ages 12-17 years had a major depressive episode in 2018-201.
However, not all are able to receive the help, in fact, parents too find themselves struggling when it comes to helping their children.
Despite growing concern about a mental health crisis among young people in the United States, a large national study suggests the care system continues to fall short for many families.
Researchers from the Harvard Pilgrim Health Care Institute in Boston found that nearly one quarter of children who require mental health treatment are not receiving it.
The findings come from survey data collected from more than 173,000 households between June 2023 and September 2024.
The analysis showed that about one in five households, or 20 per cent, had at least one child who needed mental health support. Yet among those families, nearly 25 per cent said those needs were not met.
Even families that eventually obtained care often faced significant hurdles. Nearly 17 per cent described the process as difficult and exhausting.
The research letter was published February 16 in JAMA Pediatrics.
The study found that family circumstances strongly influenced how easy it was to navigate the health care system.
Families with multiple children reported higher unmet needs at 28 per cent, compared with 21 per cent in households with only one child. Single parent households also reported more difficulty securing appointments.
Education setting played a role as well. Homeschooled children had higher unmet needs at 31 per cent compared with 25 per cent among children attending public school. Researchers suggest this may reflect the absence of school counselors and other school based support systems.
Insurance and finances created additional barriers. About 40 per cent of families covered by Medicaid or without insurance said they could not get care specifically because it was too hard to access.
In a news release, lead author Alyssa Burnett said nearly one quarter of parents reported that at least one child did not receive needed mental health care, highlighting persistent access gaps.
Researchers noted several common barriers. Families cited treatment costs, a shortage of clinicians and logistical issues such as scheduling and travel.
The study also found disparities among racial and ethnic groups. Families from minority backgrounds had higher rates of unmet needs compared with non Hispanic white households. However, Black households reported less difficulty accessing care at 13 per cent compared with 17 per cent among white households.
Experts involved in the study say improving access may require shifting where care is delivered.
Senior author Hao Yu, an associate professor of population medicine at the institute, said states should expand the child mental health workforce and integrate mental health services into primary care settings to remove barriers and improve access to needed treatment.
