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.

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.

Sleep health expert explains how falling back affects the body clock

When clocks fall back this weekend, we'll gain an hour - but does that necessarily mean better sleep? Hannah Peach, a sleep health expert at UNC Charlotte, explains how the change from daylight saving time back to standard time affects our internal body clocks, why the fall transition is easier on our bodies than the spring change and how shorter days can affect our well-being.

New study of 3000 adults connects symbolic immortality to stronger psychological well being

What does it mean to feel that a part of us will live on after we are gone? A new study of nearly 3,000 adults found that people who believed they would be remembered by others tended to report better mental health, a stronger sense of meaning and lower levels of problematic substance use and addictive behaviors. The findings point to a possible link between our sense of lasting significance and the way we cope with stress, uncertainty and mortality.

Menopause reshapes women's careers, from brain fog to changing priorities

In a qualitative analysis of 130 Reddit posts, researchers examined how perimenopause and menopause affected women's career sustainability, finding that brain fog, fatigue, mood changes, and anxiety were associated with reduced confidence, workplace performance concerns, and threats to professional identity. The accounts revealed interconnected challenges involving health, happiness, and productivity, alongside experiences of supportive managers, online peer support, reduced working hours, and career reassessment that helped some women adapt to the transition.

Why you still want dessert even when you're completely full

A 2026 narrative review examines how food liking (pleasure) and wanting (motivation) interact with hunger and satiety to influence food choices, explaining why certain foods may remain appealing even after a satisfying meal. The authors report that food reward can change independently of hunger under specific conditions, but evidence remains limited that these changes reliably predict subsequent eating or improve weight-management outcomes.

Excessive exercise disrupts dopamine regulation in the brain, study finds

Excessive physical exercise affects more than just the muscles; it can also alter brain chemistry. A new study published in the journal Neuroscience revealed that exhaustive training without adequate rest alters the regulation of dopamine in the hippocampus, a brain region closely linked to memory and the regulation of emotions.

Holistic family surroundings are essential for raising healthy children

Study highlights the hidden dangers of permanent daylight saving time

In July 2026, the US House passed legislation to make daylight saving time (DST) permanent. But a new analysis of the consequences of the "Sunshine Protection Act," reported in the Cell Press journal Current Biology on October 29, finds that this legislation would come with serious safety consequences for millions of schoolchildren across the US who would have to leave for school before sunrise, when fatal crashes with pedestrians are more likely, for much of the school year.
