(Press-News.org) DARIEN, IL – A new study to be presented at the SLEEP 2025 annual meeting found that teens with earlier, more efficient, and less variable sleep patterns at age 15 had better cardiovascular health at age 22.
Results show that several healthy sleep habits at age 15 predicted a higher (better) cardiovascular health score at age 22: falling asleep and waking up earlier, spending a lower percentage of time in bed awake, and having lower variability in total sleep time and sleep onset. In contrast, average total sleep time did not predict future cardiovascular health. Results were adjusted for potential confounders including sociodemographic characteristics and self-reported body mass index, diet, and physical activity during adolescence.
“Given the importance of sleep health for physical health and well-being in the short-term, we were not surprised to see a lasting association between adolescent sleep timing, sleep maintenance efficiency, and sleep variability with cardiovascular health in young adulthood,” said lead data analyst and study author Gina Marie Mathew, who has a doctorate in biobehavioral health and is a senior post-doctoral associate in public health in the department of family, population, and preventive medicine at Stony Brook Renaissance School of Medicine in New York. “It was unexpected, however, that with and without adjustment for potentially confounding factors, total sleep time during adolescence was not a significant predictor of cardiovascular health during young adulthood. This single null finding, of course, does not indicate that total sleep time is unimportant. Rather, when paired with other studies, these findings underscore the complexity of sleep health and the need to consider multiple sleep dimensions as potential targets for promoting and maintaining cardiovascular health.”
The American Academy of Sleep Medicine recommends that teenagers 13 to 18 years of age should sleep 8 to 10 hours on a regular basis to promote optimal health. In addition to adequate duration, healthy sleep requires appropriate timing, good quality, regularity, and the absence of sleep disturbances or disorders.
The researchers analyzed longitudinal data from sub-studies of the Future of Families and Child Wellbeing Study. The diverse sample comprised 307 adolescents; 57% were female. Sleep variables were estimated at age 15 using one week of wrist actigraphy. At age 22, cardiovascular health was assessed using the seven non-sleep factors (self-reported diet, physical activity, and nicotine exposure, and objectively measured body mass index, blood lipids, blood glucose, and blood pressure) from the American Heart Association’s Life's Essential 8, producing an average composite score.
Mathew noted that the results highlight the need for a more comprehensive approach to address the relationship between adolescent sleep health and cardiovascular health.
“Future research and recommendations should emphasize the importance of multiple dimensions of sleep health, including earlier sleep timing, higher sleep maintenance efficiency, and lower sleep variability as protective factors for long-term heart health,” she said.
This study was supported by grants from the Eunice Kennedy Shriver National Institute of Child Health and Human Development within the National Institutes of Health. The research abstract was published recently in an online supplement of the journal Sleep and will be presented as an oral presentation Sunday, June 8, 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.

Cancer cannot be understood as a single, uniform disease. The more we delve into studying each type of tumor, the more we recognize the need to subclassify the disease. This concept has led to what we now call precision oncology, characterizing the molecular features of a patient's specific cancer to determine the most effective treatment.
Prostate cancer is considered the most prevalent tumor among men, and it typically has a high cure rate. As such, although many men will be diagnosed with this cancer, the majority will be cured. "However, when we refer ...

Stress worsens sleep quality and can impair memory. Shinjae Chung, from the University of Pennsylvania, led a study to explore a neural pathway in male mice that stress may influence to cause sleep and memory disturbances.
In their JNeurosci paper, the researchers artificially activated neurons in the paraventricular nucleus of the hypothalamus (PVN) that were previously linked to stress. This experimental manipulation made mice sleep less and impaired how well mice performed in a memory task. Notably, when mice were stressed, artificially inhibiting these PVN neurons reduced stress-related memory ...
Guns are now the leading cause of death for youth in the United States. Researcher from Mass General Brigham investigated whether firearm mortality rates among U.S. children ages 0-17 changed in the 13 years following a 2010 Supreme Court ruling that applied the Second Amendment to state and local governments. In states with the most permissive firearm laws, they found evidence of 6,029 more pediatric deaths due to firearms than would have been expected based on the existing demographic trends—and more than 1,400 excess ...
Imagine having to eat something that makes you sick – just to see what’s making you ill in the first place.
That’s the harsh reality of current diagnostic tests for coeliac disease, which require people to eat large amounts of gluten for weeks in order to get an accurate diagnosis.
But this painful process could soon be a thing of the past, with WEHI researchers and industry partner Novoviah Pharmaceuticals developing a world-first blood test that can identify the condition in patients – even when they’re on gluten-free diets.

Tokyo, Japan – Across the world the demand for meat is growing, despite associated environmental and animal welfare costs. Although lab-grown – or cultured – meat could be part of the answer, scientists have yet to perfect one crucial detail: the taste.
In an article to be published in Food Chemistry, researchers from the Institute of Industrial Science, The University of Tokyo, have measured and found a way to control the key amino acids responsible for flavor in a step toward making cultured meat taste just like the real thing.
The push toward cultured meat has been adopted because conventional production is not a sustainable solution for ...
Even with today’s advanced agricultural technologies, plant diseases can still be extremely devastating to crops, causing billions of dollars in losses worldwide every year. Begomoviruses represent a prominent example of this threat—these whitefly-transmitted pathogens cause yellow leaf curl disease in peppers and can destroy up to 100% of fruit yield in affected fields across Asia, Africa, and the Americas.
Breeding crops that are resistant to begomoviruses has long been the most effective and widely used strategy for preventing such massive losses. Though usually effective, this approach has serious limitations, especially when dealing with mixed infections. Scientists ...
Kyoto, Japan -- After the island of Madagascar drifted away from India 88 million years ago, isolating it from all other landmasses, its flora and fauna evolved in seclusion. As these transformed into plants and animals completely unique to their island, Madagascar became a biodiversity hotspot unlike anywhere else on Earth.
An important facet of this biodiversity is an ecological process called endozoochory, which is when animals eat plant seeds and then poop them out somewhere else, aiding in the spread of the plants. Most research on endozoochory has focused on the roles of ...
Brain-computer interface (BCI) technology is opening an unprecedented chapter in human-machine integration by establishing direct communication between the brain and external devices. Once a science fiction concept, BCI is now reshaping the landscape of neurosurgery and neurorehabilitation. By decoding brain signals to restore lost motor, sensory, and language functions, BCIs offer new hope for individuals affected by paralysis, aphasia, and neurodegenerative diseases. But their impact extends well beyond the clinic—BCIs are poised to influence cognition, ethical governance, and national security. As this disruptive technology matures, ...
Plant fossils found in the abdomen of a sauropod support the long-standing hypothesis that these dinosaurs were herbivores, finds a study publishing June 9 in the Cell Press journal Current Biology. The dinosaur, which was alive an estimated 94 to 101 million years ago, ate a variety of plants and relied almost entirely on its gut microbes for digestion.
“No genuine sauropod gut contents had ever been found anywhere before, despite sauropods being known from fossils found on every continent and despite the group ...
