Sleep deprivation can lead to obesity and the risk of lifestyle-related diseases. This is said to be influenced by the relationship between sleep and hormones that regulate appetite. By improving your sleep, you can reduce these risks.

Although you don't seem to have any problems during sleep, there appear to be significant issues with your sleep environment and habits.

Unconscious daily habits affect sleep quality without you realizing it. When sleep quality is low, even if you get enough sleep, fatigue accumulates without being resolved.
When fatigue accumulates, you can't perform at your best at work. Improving sleep quality is directly linked to fatigue recovery, so let's review your usual habits (even just one).

Sleep deprivation can lead to obesity and the risk of lifestyle-related diseases. This is said to be influenced by the relationship between sleep and hormones that regulate appetite.

It seems you have accumulated considerable sleep debt. Sleep debt refers to "sleep deprivation that accumulates little by little every day," or, in other words, "borrowed sleep." Sleep debt cannot be easily repaid by simply catching up on sleep on your days off. It is extremely important to ensure you get enough sleep on weekdays and to be mindful of preventing sleep deprivation from accumulating.

One experiment has shown that "two weeks of 6-hour sleep leads to the same level of brain performance decline as pulling an all-nighter, and furthermore, four hours of sleep leads to brain performance declining to the same level as two all-nighters after one week."

A gap in sleep duration between weekdays and holidays can disrupt your internal clock, leading to various effects such as sleepiness, fatigue, and reduced concentration after days off. By eliminating this sleep duration gap, you can avoid these effects and perform at your best from the start of the week.

Sleep deprivation can lead to obesity and the risk of lifestyle-related diseases. This is said to be influenced by the connection between sleep and hormones that control appetite.
