Adequate amounts of quality sleep are essential to human physical and emotional well-being. For example, quality sleep can help improve outcomes for a variety of illnesses, including cardiovascular and metabolic disorders, psychiatric disorders, and dementia. , can lead to serious health problems and is highly prevalent worldwide. In the United States, 50 to 70 million adults suffer from sleep disorders, primarily insomnia. Meanwhile, a meta-analysis of 17 studies suggests that 15% of the population in China suffers from insomnia. To better understand these diseases, it is important to study the factors that promote quality sleep. Previous research has shown that a proper lifestyle, including a healthy diet and regular physical activity, is beneficial for good sleep. research is lacking.
To this end, a team of researchers from Japan, Canada and Taiwan, led by Associate Professor Javad Koohsari of the Faculty of Knowledge Science, Japan Advanced Institute of Science and Technology (JAIST), is also a part-time researcher at the same university. The Waseda University School of Sports Sciences investigated the interrelationships between sedentary behavior, physical activity, and sleep quality in a sample of the middle-aged Japanese population. A research group consisting of Professor Yukari Nagai, also from JAIST. Professor Akitomo Yasunaga of Bunka Gakuen University. Associate Professor Ai Shibata, University of Tsukuba. Professor Yung Liao of National Taiwan Normal University. Associate Professor Gavin R. McCormack of the University of Calgary and Professors Koichiro Oka and Kaori Ishii of Waseda University based their research on Japanese adults aged 40 to his 64 years. Their work was recently published scientific report.
The researchers used a contemporaneous alternative approach. It estimates the effect of replacing one activity type with another over the same period of time. Dr. Koohsari said:Participants’ schedules replaced 60 minutes of sedentary behavior or light-intensity physical activity with moderate-to-vigorous physical activity.An accelerometer monitored the participants’ level of physical activity for seven consecutive days. A questionnaire was then used to assess the sleep and rest quality of the participants.
Replacing sedentary behavior with moderate-to-vigorous exercise actually improved sleep quality. Interestingly, this association was gender-based and only seen in women. This is consistent with reports highlighting gender differences in sleep disorders. However, more research is needed to understand why these gender-based differences occur.
In summary, this study contributes to the existing research pool that provides empirical evidence that physical activity is important in promoting quality sleep. We hope that these studies will serve as a useful platform for further research into the prevention of sleep-related disorders. I have!
