- There are reports that footbaths may help sleep quality.
- The evidence score is 54, and reliability is moderate.
- This information is relevant to older adults.
Bath timing refers to the time and method of bathing.
In the context of examining sleep quality, it is treated as a factor for measuring the effect of bathing on sleep.
Findings suggest that taking a footbath may improve the quality of sleep. The research reports a result in which the evaluation of sleep quality rose after taking a footbath.
This study is a small-scale survey with 40 older adults participating. It looks in detail at how residents of a facility for older adults changed before and after the experiment. In other words, it can be said to have tracked the changes produced by an intervention carried out under specific conditions.
As a result of the study, it was shown that the score indicating sleep quality rose numerically. However, this is merely a tendency observed in this particular survey, and it is not yet sufficiently known whether the same result would occur in everyone.
Research using specialized methods has also been conducted to confirm the effect of footbaths. One study found a result in which the method of taking a footbath was effective for sleep quality.
As many as 50 older adults participated in this survey. Those included were both hospitalized patients and outpatients. Here, the method used was a randomized controlled trial (a highly reliable research method that randomly divides participants into groups and compares a group receiving no intervention with a group receiving the intervention). In other words, a procedure was followed to check whether the result might simply be due to chance.
In this way, research has been conducted on older adults in different environments. However, since the number of participants in these studies is not especially large, there is also an aspect that makes it difficult to draw conclusions from this alone.
The evidence score underlying this information is 54, and reliability is considered moderate. This indicates that although several good-quality studies have been gathered, the situation cannot yet be said to be conclusive.
The research introduced here is based on a total of 2 reported studies. When evaluating the quality of research, the method by which the study was conducted is important. One used a randomized controlled trial (a method that randomly divides participants into groups to verify the effect of an intervention), while the other used a different type of study design.
As you can see, there are various types of study designs. Therefore, when interpreting the results obtained, it is important to understand "at what scale" and "on what population" the study was conducted. In addition, because this research was conducted on older adults, it is not yet known whether the same would hold true for younger generations or people in other situations.
| Study | Design | Number of Participants | Duration | Main Result |
|---|---|---|---|---|
| American Journal of Nursing Research (2021) | Other study design | 40 people | Unknown | A positive effect was reported |
| International Journal of Science and Healthcare Research (2022) | Randomized controlled trial (RCT) | 50 people | Unknown | A positive effect was reported |
The research was conducted on 40 older adults and 50 hospitalized and outpatient older adults, with a total of 90 people participating.
Because the research population is limited to a specific age group, this serves as material for considering whether it applies to yourself.
This result is based on 2 studies.
The study designs include a randomized controlled trial (RCT) and a quasi-experimental study (other).
The reliability of the research is reported to be moderate.
Does bath timing affect sleep quality?
Research has been reported in which bath timing has a positive effect on sleep quality. This is a research finding related to sleep quality.
What population was the bath-timing research conducted on?
The subjects were 40 older adults, and 50 hospitalized and outpatient older adults. The subjects of the research were older adults.
How large is the effect shown from bath timing?
A positive effect on sleep quality has been shown as a result. This is reported as a research finding.
This research suggests that footbaths may have a positive effect on sleep quality. However, there are aspects that mean the investigation cannot yet be called sufficient, such as the fact that the subjects were limited to older adults and that there were only 2 studies. Please consider the bath timing and method that suits you, within a reasonable range. If you're curious, please also try the self-check assessment.
