Sleeping Issues & Health Risks

Recent research continues to highlight how problematic sleep — whether too little, too fragmented, or disrupted — can lead to serious health troubles. A comprehensive global study of 88,000 adults published in 2025 found that poor sleep patterns and irregular sleep-wake cycles — not just total sleep time — are linked with increased risks of severe diseases, including liver damage and even gangrene.

Beyond that, chronic bad sleep has been connected to a wide array of health problems, from metabolic disorders, hormonal imbalance, and obesity to cardiovascular disease, weakened immunity, mental health issues like anxiety and depression, and even accelerated brain aging. One 2025 review found that people suffering from sleeplessness were up to 10 times more likely to suffer depression and 17 times more likely to experience anxiety compared to those who sleep well.

This shows that sleep isn’t just a “nice-to-”have”—getting good quality, consistent sleep is foundational to both physical and mental health.
