Physical exercise improves sleep quality

Washington, Dec 4 (Prensa Latina) Poor sleep can reduce cognitive performance, attention span, judgment and emotional state of people, but by opting for physical exercises the quality of sleep improves, a specialized source revealed today.

According to the journal Physiology and Behaviour, cardiovascular diseases, obesity, neurodegenerative disorders and depression conspire against optimal rest.

Scientists found that 20 minutes of moderate exercise can compensate for a poor night’s sleep.

Cognitive performance improves during a session of moderate-intensity physical activity, regardless of a person’s sleep status or oxygen levels.

“One possible hypothesis why exercise improves cognitive performance is related to increased cerebral blood flow and oxygenation, however, our findings suggest that even when exercising in an environment with low oxygen levels, participants were still able to perform cognitive tasks better than when at rest under the same conditions,” the experts argued.

Scientists with this study reinforced the thesis that movement is medicine for the body and brain.
