Researchers at the Federal University of Sao Paulo divided 28 women and eight men with primary chronic insomnia into three exercise groups — moderate aerobic, heavy aerobic, and moderate strength — and one control group.
After the exercise session, those who did moderate aerobic exercise showed reductions in sleep onset latency (54 percent) and wake time (36 percent) and increases in total sleep time (21 percent) and sleep efficiency (18 percent). They also showed a 7 percent decrease in anxiety.
