14 DAY TRIAL // Investigators at the Oregon State University discovered in a new study that as few as 150 minutes of training or physical exercises per week – the equivalent of two and a half hours – is sufficient to improve sleep quality and daytime alertness.
The study was carried out on a representative population sample of 2,600 individuals, aged from 18 to 85. The intensity of the training sessions used for the purpose of this research was ranked as moderate to vigorous, PsychCentral reports.
A 65 percent improvement in sleep quality was reported by test subjects who carried out this exercise routine. These people also reported experiencing less drowsiness during the daytime, as opposed to how they felt before starting to exercise.
Details of the work appear in the December issue of the journal Mental Health and Physical Activity. Statistics show that about 40 percent of all adults in the United States have problem going to sleep at night and staying awake during the day.
