Studies have shown that irregular bedtime may have a huge hidden impact



There is already ample evidence that, in addition to how many hours we spend in total sleep, going to bed regularly is essential for healthy living. A new study has now found a link between interrupted sleep patterns and a higher risk of bad mood and depression.

In a study that directly measured the sleep time and mood of 2115 physicians during the first year of training, scientists found that people with variable sleep patterns were more likely to report low mood and score higher in depression symptoms.

Changes in sleep time may actually increase the risk of depression just like normal sleep time. This shows that keeping pace with the circadian rhythm is equally important to our mental health, just like adding a lot of time.

Srijan Sen, a neuroscientist at the University of Michigan, said: “These findings highlight that sleep consistency is an under-recognized factor for depression and health.”

The average age of this study is 27 years old, and after a hard first year of training, they do not represent the entire population. However, the group does provide scientists with an opportunity to study large numbers of people. There have been similar situations for several months.

As you might expect, more total sleep, getting up late, going to bed early-and sticking to a more regular sleep style-all of these can improve the mood of the participants.Maybe there is no good record before how important regular sleep is mode Related to other factors.

Data was collected through the use of sleep tracking wearable devices, smartphone apps and volunteer surveys. Speaking of wearable devices, although they may not track sleep more accurately than instruments in the laboratory, they do enable scientists to monitor the habits of many people once for a long time without affecting their daily activities (and nightly sleeping time).

“Advanced wearable technology allows us to study the behavioral and physiological factors of mental health, including sleep, on a larger scale and more accurately than before, which opens up exciting areas for us,” said neuroscientist Yu Fang. University of Michigan.

“Our findings are not only intended to guide the self-management of sleep habits, but can also inform the organization’s schedule structure.”

Although we all agree that better sleep habits are beneficial to our overall health, the team of this new study wants to see more about how different aspects of sleep hygiene (bedtime, wake-up time, sleep pattern, total sleep time) affect Personal health research. .

This new research supports previous research that showed that ignoring our circadian rhythms can damage our mood and increase the risk of depression over time. If possible, try to keep going to bed at the same time and waking up for a long time-this may reduce your mood and appearance.

Next, the researchers hope to turn their attention to other people, such as young parents, who may not necessarily fully control when they go to bed, when they wake up, and how many hours of sleep between them. , E.g.

Fang said: “I also hope that my one-year-old child can understand these findings, and can only wake me up at 8.21 in the morning every day.”

The research has been published in npj digital medicine.
