Academics have pinpointed five unique “sleep patterns.”
And, according to their study, the scientists inferred that a sound slumber encompasses more than just its duration or degree of restfulness. Both genetic inheritance and emotional conditions, such as feeling dejected, uneasy, tense, or mournful, play a role in sleep quality. Each sleep pattern was connected to how individuals performed across different domains, the researchers communicated in a piece published Oct. 7 in the journal PLOS Biology.

The authors penned that, as scientists recognize, people with deficient sleep are at considerably heightened likelihood of acquiring depression, worry, heart conditions, and diminished cognitive performance, and frequently have lessened lifespans.
However, the justification and course of correlation regarding such relationships has remained ambiguous, and a majority of earlier studies didn’t truly categorize sleep with a thorough level of detail.
To correct this problem, the research team employed data derived from the Human Connectome Project, an effort that charts connections among nerve fibers throughout the human brain, in an attempt to produce a more comprehensive understanding of sleep quality alongside its correlation to well-being.
This dataset incorporates brain scans and a substantial variety of self-reported particulars concerning each individual’s way of life, mental and physical fitness, and also personality traits and sleep attributes — like typical sleep duration, difficulty staying asleep, and the employment of sleep aids.
Participants identified as having clinical depression were excluded from the study; nonetheless, if people in the dataset demonstrated subclinical indicators of stress or depression that didn’t hinder their day-to-day functioning, their data was incorporated. Perrault explained that the researchers concentrated on data from 770 participants aged 22 to 36, whose sleep was probably not impacted by the aging course.
By utilizing unsupervised machine learning, a method that employs artificial intelligence to dissect data without predetermined categories, the scientists unearthed statistical associations between specified lifestyle traits, brain imaging data, and sleep features.
Participants were directed to assess their sleep quality over the prior month with the Pittsburgh Sleep Quality Index. The paper pointed out that a score of 5 or under is deemed indicative of a good sleeper, and the average score within the studied population reached 5.14, on a scale from 0 to 19.

Although there existed individuals with good sleep, the investigators’ interest lay more with participants presenting scores exceeding 5. This yielded a categorization into five sleep patterns. As an illustration, “poor sleepers” include people who face challenges in sleeping, and encounter states of mental distress, like unease, whereas “disturbed sleepers” are persons whose sleep encounters disruptions to the degree that it compromises their welfare and rational processes.
The five sleep profiles
1. Poor sleepers – These individuals found it difficult to fall asleep and remain asleep. Also, they frequently faced mental wellness problems such as feelings of worry, despondency, irritation, or strain in addition to diminished performance during the day.
2. Sleep-resilient — Despite having mental health obstacles, like inattention, Attention Deficit Hyperactivity Disorder, and challenges regarding thought and focus during the day, they reported no sleep issues.
3. Short sleepers — They did not sleep for extended periods and faced challenges with thought and recall, and also aggression and reduced agreeableness.
4. Sleep-aid users — Their slumber habits were predominantly influenced by their use of sleep aids, spanning from over-the-counter medicines, CBD (cannabidiol) with or without THC (tetrahydrocannabinol), chamomile beverage, or prescription drugs.
5. Disturbed sleepers — Their sleep was frequently disrupted, potentially as a result of drinking alcohol or smoking cigarettes, or due to dehydration, that influenced their health and daily living.
Each pattern also connects to a “neural signature,” which denotes a brain response encompassing details regarding the individual’s ongoing sensations at that period, for example body temperature, nightmares or variations in hormone levels.
Perrault observed that this leads to the notion that sleep profiles are linked with the brain’s composition and indicators of well-being.
Dr. Henry Yaggi, who serves as a professor of internal medicine and heads the Yale Centers for Sleep Medicine, applauded the study’s technique. “It embodies a far more extensive sleep evaluation than what we’ve encountered in prior times,” expressed Yaggi, an individual unassociated with the research. “This isn’t a singular, universal solution,” he communicated to Live Science. “Sleep showcases patterns exhibiting associations with mental wellness.”

Perrault infers the five sleep patterns could potentially be utilized as biomarkers, or quantifiable indicators of conditions that might occur down the line. Yaggi shared that because the patterns were defined in healthy young grownups, further probes are required to determine whether they could serve as biomarkers, perhaps in identifying unfolding anxiety and depression.
Both Perrault and Yaggi communicated to Live Science their sentiment of potential for the five sleep profiles to provide direction in clinical interventions. As an instance, selected approaches such as talk therapy, sleep apps, and continuous positive airway pressure (CPAP) devices intended to enhance sleep could be more effective for “short sleepers” in contrast to “sleep-aid users.” Overall, this avenue of study could also bring clarity to the explanation behind why roughly 40% of patients exhibit resistance to cognitive behavioral therapy for insomnia (CBT-I), a form of talk and behavioral therapy, Perrault appended.
