In Philip’s 5th annual Global Sleep Survey, which included people from 13 countries, only half of adults said they were satisfied with their sleep, and most said they were not getting enough.
Long-term sleep deprivation is related to numerous chronic diseases, including diabetes and heart disease. Research has shown that sleep loss is a risk factor for developing low glucose tolerance.
Recently, in a study of 24 healthy young men, Australian and American researchers found that high-intensity interval training prevented impairments in glucose tolerance, among other negative effects, from a short period of sleep restriction.
Subjects were divided into three groups: normal sleep; 5 nights of sleep restriction; and sleep restriction plus three HIIT sessions. Those in the sleep restriction group experienced a decrease in glucose tolerance, along with other adverse effects, while those in the HIIT group did not. Study authors noted that future evidence-based health guidelines and recommendations for people who don’t get enough sleep could include interventions such as exercise.
The research is open-source and is available in Molecular Metabolism (2020; doi:10.1016/j.molmet.2020.101110).
