Sleep

Sleep is a physiological behavior that is common in all animal species. It forms around one third of a human life. It is not known clearly the exact functions of sleep but it seems to be essential for survival as prolonged sleep deprivation leads to severe physical impairment followed by cognitive loss and eventually death.

Graded physical activity prescriptions improve functional outcomes in psychiatry

Most of us have heard the advice so often that it has worn smooth, like a stone in a river: get some exercise. A new peer-reviewed Viewpoint in Brain Health, drawing on randomized trials, meta-analyses, and cohort studies, argues that this familiar sentence has been doing the wrong job.

Caffeine intake rises among Korean adults as brewed coffee gains ground

An analysis of 48,991 Korean adults found that average daily caffeine intake from beverages increased between 2016 and 2024, while the odds of consuming at least 400 mg of caffeine on a single day rose by approximately 5% annually. Coffee remained the predominant caffeine source, with a shift from prepared coffee mixes toward brewed coffee and distinct consumption patterns across age groups and sexes.

Modern lifestyles may be changing our gut bacteria in unexpected ways

A global study of 1,015 adults across 12 countries found that industrialized lifestyles were associated with lower gut bacterial diversity, reduced microbial community stability, and increased markers of intestinal stress and immune activity. The researchers also found that a microbiome-based health index developed using industrialized populations performed poorly in less-industrialized communities, raising concerns about its applicability across diverse populations.

Exercise may improve mood and memory, and researchers say doctors should prescribe it

In a Viewpoint, researchers examined evidence that exercise can reduce symptoms of depression and anxiety, support cognition, and may help lower the risk of cognitive decline, although evidence for dementia prevention remains largely observational. The authors argue that exercise should be prescribed as a structured component of brain-health care, with individualized recommendations that account for medical conditions, safety, and barriers to participation.

Pulse oximeter bias undercounts sleep apnea severity in Black patients

Sleep studies often use a pulse oximeter to determine the severity of sleep apnea. But a new study by investigators from Mass General Brigham reports that pulse oximeters may undercount breathing events in Black patients, potentially leading to inaccurate severity classifications.

Wearable devices and AI provide early warning signs of hypertensive crises

Using artificial intelligence (AI) to analyze patterns in measures from a portable cuff-based blood pressure monitor and health data from a wrist-worn device may help identify when adults with stage 2 high blood pressure (blood pressure ≥140/90 mm Hg) are at increased risk of a dangerously high blood pressure episode (>180/120 mm Hg with acute end-organ damage), known as a hypertensive crisis, up to three days before it occurs, according to new, independent, preliminary research to be presented at the American Heart Association's Scientific Sessions 2026.

More screen time, less sleep: What researchers observed in children with obesity

A cross-sectional study of 70 children in Spain found that those with obesity reported more daily recreational screen time, shorter sleep duration, and more frequent chronic sleep disturbances than their normal-weight peers. Higher screen-time scores were significantly associated with greater odds of obesity, while the association with sleep disturbances did not reach statistical significance.
