Prolonged lack of sleep significantly increases the likelihood of early death and weakens the immune system, according to recent studies.
Research by a team of U.S.-based scientists and doctors, published by the American Medical Association (AMA), found that insufficient sleep over a five-year period raises the risk of “all-cause mortality” by 29%. The study, which involved 46,000 participants, underscores the importance of maintaining a healthy sleep routine—ideally 7 to 8 hours per night—to safeguard long-term health.
The negative effects of sleep deprivation go beyond just feeling tired. A study published in The Journal of Immunology revealed that even a single night of poor sleep can impair immune function, potentially leading to inflammation and increasing vulnerability to illness. When sleep deprivation persists, it can lead to chronic inflammation and a weakened immune response, making individuals more susceptible to a range of health issues.
The research further indicates that while obesity can contribute to inflammation, poor sleep is an independent risk factor, making it critical for overall well-being.
Inadequate sleep, when sustained over time, not only affects physical health but also puts mental and emotional health at risk, further highlighting the need for good sleep hygiene to prevent serious health consequences.
