Physical activity can keep you awake, new research finds
A good workout during the day can keep you awake, new research suggests, rather than promoting a good night’s sleep as was previously thought.
An American study of 14 exercisers over 23 days showed that the more active they were, the less they slept.
On days when the participants were least active, they slept for an average 42 minutes longer.
Dr Arn Eliasson, of the Walter Reed Army Medical Centre in Washington DC, who led the research, said that the results were the opposite of those expected.
‘The longest sleep and best sleep efficiency occurred after days with low non-exercise exertion,’ he said.
He also expected that people who had slept the best, would be most active the day afterwards, but the opposite was true. Those who had the most rest were least active the next day, according to the Telegraph.
