- It has been suggested that the habit of keeping a consistent bedtime may be related to sleep quality.
- The evidence score is 39, and the reliability is currently considered limited.
- This information is intended for those who want to know about changes in sleep quality and their daily life rhythm.
Bedtime regularity refers to going to sleep at a consistent time, or the periodicity of sleep.
This is one of the elements that make up lifestyle habits, and it is a concept handled in the context of managing daily life rhythm.
There are reports that a lifestyle rhythm that keeps bedtime consistent has a positive effect on sleep quality. Research has reported that bedtime regularity has a positive effect on sleep quality (1 study, limited reliability).
This study targeted 19 adults with type 1 diabetes who lead a sedentary lifestyle. The investigation was conducted over a period of 42 days, examining how factors related to lifestyle habits are involved in sleep. As a result, it was confirmed that sleep quality improved by 21.4% in one group. In other words, this suggests the possibility that daily rhythm and the content of activity are related to sleep status.
This study was conducted as a randomized controlled trial (a reliable research method in which participants are randomly assigned to compare effects). In other words, it followed standard procedures for scientifically verifying the effect of a specific factor.
The data introduced here is based on 1 report. The evidence score is 39, and at this point the reliability is considered low.
This is related to the conditions and nature of the study. Since the number of participants in the study was small, at 19, this result may not apply to everyone. In addition, since the number of studies is also limited, it has not yet reached the point of being definitively established as fact. In other words, at this stage, it is appropriate to receive this as data showing a single trend.
This investigation focused on people leading a sedentary lifestyle. The subjects of the research were 19 adults with type 1 diabetes.
Since these are results under such specific conditions, they do not necessarily apply as-is to all lifestyles. The way sleep is experienced may also vary depending on individual constitution and environment. In other words, it is important to first regard this as a single case example.

This research was conducted on 19 sedentary adults with type 1 diabetes.
Knowing the attributes and activity status of the subjects can serve as material for considering whether you are close to the conditions of this research.
This report is based on 1 study.
It should also be noted that the number of research subjects was small, at 19.
The reliability of the research data is stated to be limited.

What subjects was the bedtime regularity research conducted on?
It targeted 19 sedentary adults with type 1 diabetes. This is based on the results of a randomized controlled trial (RCT) conducted under those conditions.
How reliable is the information on bedtime regularity?
The reliability of the reported content is stated to be limited. This is a description based on the research data.
There are reports that the habit of keeping a consistent bedtime may have a positive effect on sleep quality. However, since the number of studies is 1 and the number of participants is also limited this time, it should be noted that the reliability is limited. The current research data suggests the possibility that lifestyle rhythm has some effect on sleep.
If you're concerned about your own sleep rhythm, why not start with a self-check?
