Moderate Exercise May Help Insomnia
A session of moderate aerobic exercise can reduce anxiety and improve the quality of insomnia patients' sleep, a Brazilian researcher says.
Giselle S. Passos of Federal University of Sao Paulo in Brazil divided 36 patients -- eight men and 28 women -- with primary chronic insomnia into three experimental groups -- moderate aerobic exercise, heavy aerobic exercise and moderate strength exercise -- and a control group.
In the moderate aerobic exercise group, 37 percent had a significant increase in total sleep time and 40 percent reduced their sleep onset latency. In addition, a significant reduction in the anxiety state was also observed after moderate aerobic exercise.
The findings were presented at the 22nd annual meeting of the Associated Professional Sleep Societies in Baltimore.
