Aerobic Exercise Improves Sleep Quality

Another study has found that exercise improves sleep in middle-aged and older adults. Forty adults who complained of poor sleep quality were randomized into a 12-week exercise group or a control group. Exercise consisted of 40 minutes of supervised aerobic exercise training and 10 minutes of stretching class, 3 times a week for 12 weeks. Outcome measures included subjective and objective sleep quality assessments. The researchers found that the exercise group showed significant improvements in sleep quality compared to the control group. They conclude that moderate-intensity exercise training has a beneficial effect on sleep quality in middle-aged and older adults with poor sleep.
