Long-term sleep deprivation may increase the risk of diabetes, which is closely linked to disruptions in the body’s hormonal balance and metabolic function. Below is a detailed explanation of this connection and its related effects.
Insomnia or staying up late triggers increased secretion of glucose-raising hormones such as adrenaline and cortisol. Excessive secretion of these hormones counteracts the blood glucose-lowering effect of insulin, leading to persistently elevated blood sugar levels. Over time, pancreatic islet cells must work overtime to maintain normal blood glucose levels, which may eventually result in impaired function.
Sleep deprivation reduces the body’s sensitivity to insulin. This means body cells struggle to take up glucose efficiently, causing a further rise in blood glucose levels. Studies show that staying up late for several consecutive days can induce insulin resistance, and even short-term sleep deprivation may lead to abnormal blood glucose the next day.
Long-term lack of sleep can create a vicious cycle of metabolic disorders. For example, chronic sleep deprivation may contribute to obesity and fatty liver, which in turn interact with insulin resistance. Hypoxia caused by sleep disorders such as sleep apnea also damages pancreatic β‑cells, accelerating the progression of diabetes.
In addition to the internal physiological factors mentioned above, staying up late is often accompanied by unhealthy lifestyle choices, including irregular eating habits, excessive intake of high-sugar and high-fat foods, and physical inactivity. These factors collectively increase the metabolic burden.Statistics show that the prevalence of diabetes among young people aged 18–29 has reached an alarming 2%, which is strongly associated with common habits such as staying up late and a sedentary lifestyle.
To prevent diabetes, maintaining a healthy lifestyle is crucial.It is recommended to get 7–8 hours of regular sleep daily and avoid overeating or consuming excessive high-sugar foods before bedtime.If needed, regular fasting blood glucose testing is also advisable.When fasting blood glucose exceeds 5.6 mmol/L, further examination is recommended to ensure early detection and control of diabetes risk.
A healthy lifestyle not only helps prevent diabetes but also supports overall physical health.
