Sleep Disorders

Disrupted circadian rhythms are often associated with poor sleep. For decades, poor sleep has been suspected to contribute to both dementia and heart disease

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

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
