Summary
Over six months, two groups were studied. One group exercised in the afternoon every day. The other group had little or no exercise. The people in the group that exercised were found to have 33 percent more deep-sleep compared to the group that had little or no exercise. Researchers hypothesize this is because afternoon exercise raises the body temperature slightly until after bedtime, which induces deeper sleep.
Strongly Supported Conclusions
Other activities that raise a person’s body temperature slightly before bedtime may cause that person to have increased levels of deep-sleep.
