Does sleep time vary every time? ... If it differs by more than 90 minutes, risk of 'this disease'

Irregular sleep patterns → disruption of circadian rhythm → interference with glucose metabolism and decreased insulin sensitivity → diabetes

According to research findings, individuals with a sleep time variation of 31 to 45 minutes have a 15% higher risk of diabetes compared to those with a variation of 30 minutes or less (the person with the smallest variation). In particular, those with a sleep time variation of 91 minutes or more have a 59% higher risk of diabetes. This suggests that irregular total sleep time, such as sleeping more than an hour and a half longer and then sleeping less, can relatively increase the risk of developing diabetes.

For example, hormones such as insulin and steroids, which are less active during sleep, generally have lower levels. In the morning, hormone levels increase to meet activity demands. Experiencing sleep disorders can cause a sharp decline in the utilization of glucose and fats.

"Owl-shaped humans have a higher risk of diabetes compared to morning people"... Bright bedroom lighting is not good.

It has been found that "owl-type humans" are at a much higher risk of developing Type 2 diabetes compared to "morning-type humans." Whether people go to bed early and wake up early or wake up late is closely related to their circadian rhythm, which explains their biological clock. In particular, it is greatly affected by the brightness (illuminance) of the bedroom lighting. Sleeping with the lights on or having too bright lighting is not good.

Pre-diabetes (impaired glucose tolerance) is a warning sign that indicates a high risk of developing type 2 diabetes.

If not properly managed, it can lead to cardiovascular disease. By 2025, approximately 380 million people worldwide are expected to be diagnosed with diabetes.
