How late college students go to sleep is influenced by the need to belong
Study is the first to identify the need to belong as a potential driver of social bedtime procrastination and short sleep
2025-06-04
(Press-News.org) DARIEN, IL – A new study to be presented at the SLEEP 2025 annual meeting found that bedtime procrastination among college students is socially influenced by the need to belong.
Results show that sleep duration was more than an hour shorter on school nights when college students delayed their bedtime for in-person social leisure activities. On these nights, their bedtime was strongly correlated with the timing of their last objectively measured social interaction with friends. Students within the bedtime procrastination social network scored higher on the need to belong compared with students outside the network. The need to belong also predicted tie formation within the bedtime procrastination social network.
“As far as we know, this is the first study to identify 'need to belong' as a potential driver of social bedtime procrastination and short sleep,” said principal investigator Joshua Gooley, who has a doctorate in neurobiology and is an associate professor with the Neuroscience and Behavioural Disorders Programme at Duke-NUS Medical School in Singapore.
According to the American Academy of Sleep Medicine, sleep is essential to health. The AASM recommends that adults should sleep 7 or more hours per night on a regular basis to promote optimal health. Bedtime procrastination — choosing to go to bed later despite being aware of its potential negative consequences — reduces the opportunity to get sufficient sleep.
The study involved a sample of 104 university students in a residential college, including 59 women. They wore an actigraph and a proximity beacon watch for two weeks during the school semester to estimate their nocturnal sleep and track when they were near one another. Participants also completed daily diaries. The Need to Belong Scale assessed individual differences in the desire for acceptance and belonging.
Gooley noted that the strength of their findings was surprising.
“We often think of sleep loss as being caused by screen time or work, but social needs, especially in group-living environments, can be just as powerful at influencing sleep,” he said.
The study was supported by funding from the Singapore Ministry of Education and the National Research Foundation in Singapore. The research abstract was published recently in an online supplement of the journal Sleep and will be presented Wednesday, June 11, during SLEEP 2025 in Seattle. SLEEP is the annual meeting of the Associated Professional Sleep Societies, a joint venture of the American Academy of Sleep Medicine and the Sleep Research Society.

The Unexpected Planet
Star TOI-6894 is just like many in our galaxy, a small red dwarf, and only ~20% of the mass of our Sun. Like many small stars, it is not expected to provide suitable conditions for the formation and hosting of a large planet.
However, as published today in Nature Astronomy, an international team of astronomers have found the unmistakable signature of a giant planet, called TOI-6894b, orbiting this tiny star.
This system has been discovered as part of a large-scale investigation of TESS (Transiting Exoplanet ...

A study led by researchers at Stanford Medicine shows that differences in blood sugar responses to certain carbohydrates depend on details of an individual’s metabolic health status.
The differences in blood sugar response patterns among individuals were associated with specific metabolic conditions such as insulin resistance or beta cell dysfunction, both of which can lead to diabetes. The study findings suggest that this variability in blood sugar response could lead to personalized prevention and treatment strategies for prediabetes and diabetes.
“Right now, the American Diabetes Association ...

Even with all its training and computer power, an artificial intelligence (AI) tool like ChatGPT can’t represent the concept of a flower the way a human does, according to a new study.
That’s because the large language models (LLMs) that power AI assistants are based usually on language alone, and sometimes with images.
“A large language model can’t smell a rose, touch the petals of a daisy or walk through a field of wildflowers,” said Qihui Xu, lead author of the study and postdoctoral researcher in psychology at The Ohio State ...

Extractive activity in international waters - including fishing, seabed mining, and oil and gas exploitation - should be banned forever, according to top scientists.
The high seas, the vast international waters beyond national jurisdiction, remain largely unprotected and are increasingly threatened.
Writing in the journal Nature, Professor Callum Roberts and co-authors argue that stopping all extractive activity in international waters would prevent irreversible damage to marine biodiversity, the climate, and ocean equity.
This would ...

A team of international researchers has developed a new biological age “clock” that estimates how well someone is aging, not just how “old” they or their various organs might be. The IC Clock, which is described in a study in Nature Aging, measures intrinsic capacity (IC), the sum of six key functions that determine healthy aging: mobility, cognition, mental health, vision, hearing and nutrition/vitality.
“Maintaining function during the aging process is what matters to older adults. Function should inform medical care instead of focusing on getting patients to some disease-free state,” said senior ...

Tokyo, Japan – Water is everywhere and comes in many forms: snow, sleet, hail, hoarfrost… However, despite water being so commonplace, scientists still do not fully understand the predominant physical process that occurs when water transforms from liquid to solid.
Now, in an article recently published in the Journal of Colloid and Interface Science, researchers from the Institute of Industrial Science, The University of Tokyo, have carried out a series of molecular-scale simulations to uncover why ice forms ...

A simple rule that seems to govern how life is organised on Earth is described in a new study published today (Wednesday, 4 June) in Nature Ecology & Evolution.
The research team led, by Umeå University and involving the University of Reading, believe this rule helps explain why species are spread the way they are across the planet. The discovery will help to understand life on Earth – including how ecosystems respond to global environmental changes.
The rule is simple: in every region on Earth, most species cluster together in small 'hotspot' areas, then gradually spread outward with fewer and fewer species able to survive farther away from these ...

Over 500 million people worldwide suffer from diabetes—a disease that contributes to major complications such as stroke, kidney failure, cancer, and Alzheimer’s disease. At the heart of this condition lies the dysfunction of pancreatic islets, the mini-organs called organoids responsible for regulating blood sugar, in both autoimmune type 1 diabetes and stress-induced type 2 diabetes. Replacing these damaged islets with lab-grown, functional islets represents a promising therapeutic strategy. However, the lack of reliable markers to identify truly functional, stem cell–derived islets has hindered the consistent production needed for clinical application.
In ...

The host star, TOI-6894, is a red dwarf with only 20% the mass of the Sun, typical of the most common stars in our galaxy. Until now, such low-mass stars were not thought capable of forming or retaining giant planets. But as published today in Nature Astronomy, the unmistakable signature of a giant planet — TOI-6894b — has been detected in orbit around this tiny star.
This exceptional system was first identified in data from NASA’s Transiting Exoplanet Survey Satellite (TESS), as part of a large search for giant planets around small stars, led by Dr. Edward Bryant from UCL’s ...
