School bans alone not enough to tackle negative impacts of phone and social media use

First study of its kind finds that restrictive school policies don’t lead to lower phone and social media use overall, nor better outcomes among students

2025-02-05

(Press-News.org) Students attending schools that ban the use of phones throughout the school day aren’t necessarily experiencing better mental health and wellbeing, as the first worldwide study of its kind has found that just banning smartphones is not enough to tackle their negative impacts.

In a landmark study published today (Wednesday 5 Feb) in Lancet Regional Health Europe, 1227 students from 30 schools across England provided data about smartphone and social media usage and a range of mental health, wellbeing and other outcomes. Among the schools that took part in the study, 20 had various forms of restrictive phone policies in place.

The study, which was funded by the National Institute for Health and Care Research (NIHR), found that there was no difference in outcomes for students who attend schools that ban smartphones throughout the school day, including:

Mental wellbeing, anxiety and depression Physical Activity and Sleep Educational Outcomes – English and Maths attainment and levels of disruptive classroom behaviour

Smartphone bans in schools did lead to a slight decrease in students using phones (of approximately 40 minutes) and social media (approx. 30 minutes) in school, but the study suggests that the impact is small and that school policies banning recreational phone use didn’t lead to a meaningful reduction in the overall time spent using phones and social media.

Dr Victoria Goodyear, Associate Professor at the University of Birmingham and lead author of the study said:

“This is the first worldwide study of its kind to evaluate the impact of school phone policies on adolescent mental health and wellbeing, and other health and educational outcomes.

“We did find a link between more time spent on phones and social media and worse outcomes, with worse mental wellbeing and mental health outcomes, less physical activity and poorer sleep, lower educational attainment and a greater level of disruptive classroom behaviour.

“This suggests that reducing this time spent on phones is an important focus. But we need to do more than focus on schools alone, and consider phone use within and outside of school, across a whole day and the whole week.”

Data from students was collected more than a 12-month period ending in November 2023 from 20 schools with restrictive phone policies and 10 schools with permissive policies, where a phone could be used at breaks, lunch or in certain zones (such as outside areas). The 2:1 ratio of restrictive and permissive schools was used, as among schools in the study sampling area, the majority (n=1245) had restrictive policies while few (n=96) had permissive policies.

Health and related outcomes included validated measures of mental wellbeing, anxiety and depressive symptoms, educational attainment in English and Maths, and disruptive classroom behaviour, and objective measures of physical activity and sleep.

Among all students in both permissive and restrictive policy schools, smartphone use was on average between 4-6 hours per day.

Professor Miranda Pallan from the University of Birmingham, and a senior author of the paper said:

“Our study suggests that school policies are not the silver bullet for preventing the detrimental impacts of smartphone and social media use.

“The paper shows that restrictive policies on recreational phone use in schools do not lead to better outcomes among students, but that addressing overall phone use should be a priority for improving health and wellbeing among adolescents.”

Imagine being summoned as a juror in a murder trial. The expert responsible for analyzing DNA traces at the crime scene has just explained that they match the defendant’s profile. “Then the culprit must be them,” you think. At this point, however, the expert adds: “The sample, however, is partially degraded.” What does this mean? How does this information affect your judgment? The scientist further explains that there is a one-in-a-billion probability that other people could match the identified genetic profile. ...

‘Living’ electrodes breathe new life into traditional silicon electronics

2025-02-05

Osaka, Japan – High-speed electronic devices that do not use much power are useful for wireless communication. High-speed operation has traditionally been achieved by making devices smaller, but as devices become smaller, fabrication becomes increasingly difficult. Have we reached a dead end? Not yet! A research team at Osaka University is exploring another way to improve device performance: placing a patterned metal layer, i.e., a structural metamaterial, on top of a traditional substrate, e.g., silicon, to accelerate ...

One in four chance per year that rocket junk will enter busy airspace

2025-02-05

There’s a 26 per cent annual chance that space rocket junk will re-enter the atmosphere and pass through a busy flight area, according to a recent UBC study. While the chance of debris hitting an aircraft is very low, the research highlights that the potential for uncontrolled space rocket junk to disrupt flights and create additional costs for airlines and passengers is not. Space junk disrupting air traffic is far from unheard of. In 2022, a re-entering 20-tonne piece of rocket prompted Spanish and French aviation authorities to close parts ...

Later-onset menopause linked to healthier blood vessels, lower heart disease risk

2025-02-05

Women who go through menopause later in life have healthier blood vessels for years to come than those who go through it earlier, according to new University of Colorado Boulder research. The study, published in the American Heart Association journal Circulation Research, offers new insight into why females who stop menstruating at age 55 or later are significantly less likely to have heart attacks and strokes in their postmenopausal years. Arriving just in time for Women's Heart Health Month, in February, the findings could help lead to new therapies, including dietary interventions, to reduce risk of heart ...

New study reveals how RNA travels between cells to control genes across generations

2025-02-05

RNA-based medicines are one of the most promising ways to fight human disease, as demonstrated by the recent successes of RNA vaccines and double-stranded RNA (dsRNA) therapies. But while health care providers can now successfully develop drugs that use dsRNA to accurately target and silence disease-causing genes, a major challenge remains: getting these potentially life-saving RNA molecules into cells efficiently. A new study published in the journal eLife on February 4, 2025, may lead to breakthroughs in RNA-based drug development. University of Maryland researchers used microscopic roundworms ...

Women health sector leaders good for a nation’s wealth, health, innovation, ethics

2025-02-05

Women health sector leaders are good for a nation’s wealth, health, innovation, and ethics, among other things, finds a review of the available evidence, published in the open access journal BMJ Global Health. Yet despite their unique and positive impact, they are a major underused resource, particularly in low and middle income countries, say the researchers, who call for more and sustained investment to maximise women’s potential and reap the benefits of their contribution. Despite making up 70% of the healthcare workforce, as a whole, and 90% of the nursing ...

‘Good’ cholesterol may be linked to heightened glaucoma risk among over 55s

2025-02-05

‘Good’ (HDL) cholesterol, usually considered to be beneficial for health, may be linked to a heightened risk of the serious eye condition, glaucoma—at least among the over 55s— suggest the results of a large observational study, published online in the British Journal of Ophthalmology. Paradoxically, ‘bad’ (LDL) cholesterol, usually regarded as harmful to health, may be associated with a lower risk of glaucoma, a condition that damages the optic nerve, potentially leading to irreversible sight ...

GLP-1 drug shows little benefit for people with Parkinson’s disease

2025-02-05

The GLP-1 drug, exenatide, has no positive impact on the movement, symptoms or brain imaging of people with Parkinson’s, finds a new study led by UCL researchers. The world’s largest and longest trial of exenatide in people with Parkinson’s disease was funded by the National Institute for Health & Care Research (NIHR) with support for sub-studies from Cure Parkinson’s and Van Andel Institute. For their research, published in The Lancet, the team designed a randomised controlled phase 3 trial to definitively determine whether exenatide use was associated with any benefit in people with Parkinson’s and ...

Generally, things really do seem better in morning, large study suggests

2025-02-05

Generally, things really do seem better in the morning, with clear differences in self-reported mental health and wellbeing across the day, suggest the findings of a large study published in the open access journal BMJ Mental Health. People generally wake up feeling in the best frame of mind in the morning but in the worst around midnight, the findings indicate, with day of the week and season of the year also playing their part. Mental health and wellbeing are dynamic in nature, and subject to change over both short and extended periods, note the researchers. But relatively few studies have looked at how these might change over the course of the day, and those studies that ...

Juicing may harm your health in just three days, new study finds

“Most people think of juicing as a healthy cleanse, but this study offers a reality check” CHICAGO --- Think your juice cleanse is making you healthier? A new Northwestern University study suggests it might be doing the opposite. The study, recently published in Nutrients, found that a vegetable and fruit juice-only diet — even for just three days — can trigger shifts in gut and oral bacteria linked to inflammation and cognitive decline. How was the study conducted? Northwestern scientists studied three groups of healthy adults. One group consumed only juice, another had juice with whole ...
