With rising sleep disorders, specialists say loud, regular snoring may be an early clue to conditions affecting oxygen levels and overall health
From early awakenings to lighter sleep, ageing changes how we rest. A neurologist explains when disturbed sleep is normal, when it points to disease, and what to do to rest better
Circadian rhythm makes up a roughly 24-hour internal clock that governs sleep-wake cycle as well as ebbs and flows of hormones, metabolism, cardiovascular function, immune system, appetite and mood
Disrupted circadian rhythms are often associated with poor sleep. For decades, poor sleep has been suspected to contribute to both dementia and heart disease
National Youth Day: Seeing more patients who look older than their years, a doctor says modern work-life habits are quietly affecting sleep, hormones, metabolism and long-term heart health
Hot nights may be stressing ageing hearts. A new Australian study finds that bedroom temperatures above 24 degrees Celsius during sleep can disrupt heart recovery in older adults
Researchers have developed an artificial intelligence model that can predict one's risk of developing over a hundred different health conditions using sleep data. Named 'SleepFM', the model was developed by researchers, including those from the US' Stanford University, and trained on nearly six lakh hours of sleep data, collected from 65,000 participants. The AI system, described in a paper in the journal Nature Medicine, was initially tested on standard tasks involving sleep analysis, such as tracking different stages of sleep or diagnosing severity of sleep apnoea. The model was then used to predict the future onset of disease by analysing sleep data, with health record data sourced from a sleep clinic. More than 1,000 disease categories in the health records were looked at and 130 could be predicted with reasonable accuracy using a patient's sleep data, the researchers said. "We record an amazing number of signals when we study sleep. It's a kind of general physiology that we s
Doctors explain how brain development, hormones and the body clock affect how much sleep is healthy at every stage of life
A large US study tracking sleep and longevity across counties finds that insufficient sleep may shorten life expectancy more than poor diet or lack of exercise, second only to smoking
Chronic stress and poor sleep are linked to reduced levels of natural killer cells, according to a new study highlighting the hidden immune cost of anxiety and insomnia
Just as the circadian rhythm keeps time with the 24-hour rotation of the Earth, many organisms also track the slower rhythm of the Moon
From restless nights to oversleeping, irregular sleep habits make your brain age faster, raising the risk of forgetfulness, cognitive decline, and even dementia, says a new study
A large MRI-based study of 27,500 adults finds that poor sleep may make the brain look up to a year older than its real age, suggesting that better sleep could slow brain ageing
Chronic insomnia appears to accelerate the trajectory towards dementia, not through one pathway but several
Sleep irregularity is not just bad for rest-it may be a hidden trigger for liver, metabolic, and chronic diseases, says biohacker Bryan Johnson, citing new wearable-tracked data
From late-night chores to early alarms, Indian women's sleep is sacrificed for the family's routine
UC Berkeley researchers show how deep sleep triggers growth hormone release that aids muscle growth, fat burn, and cognitive health - and why poor sleep disrupts it all
Frequent urination at night is common but not always harmless. Doctors highlight the risks, underlying causes, and practical steps you can take to improve sleep and protect your health
Indian trial finds that regular conch shell blowing may improve sleep quality, reduce breathing interruptions, and ease daytime sleepiness in people with moderate obstructive sleep apnoea
If you dread going to bed or lie awake worrying about sleep quality, you may have sleep anxiety-experts explain what it is, what causes it, and how to treat it
