For those who are looking for a good excuse to skip a workout, we have bad news. One of the most popular myths – that late night exercise will disrupt your sleep – has pretty much been debunked. The folks over at upwave, Turner Broadcasting’s new lifestyle site, took this very popular and time honored excuse to task and found that science just does not back it up.
One of the reasons the myth is so often used is probably that it kind of makes sense. A good workout increases heart rate and core body temperature, and releases adrenaline, all of which would seem to be antithetical to the calm, peaceful rest of a goodnight’s sleep. But the article cites a 2011 study that showed that the vast majority of people’s sleep was not adversely affected in the slightest by a workout 35 minutes before bedtime.
Also cited is a 2013 poll by the National Sleep Foundation in which 83 percent of participants who exercised at any time of day reported better sleep than those who did not workout at all. The time of the exercise did not matter, any workout was better than no workout for a better night’s rest. Also, over half of the respondents who were moderate or vigorous exercisers reported better sleep on workout days over rest days. Only three percent of late night exercisers reported worse sleep after a workout.
Of course, three percent is not zero. Exercise, while a net positive for just about everyone, still can affect the bodies of people in ways particular to them. So, if you do find yourself struggling to get to sleep after a late workout, perhaps try to schedule future exercise for an earlier time. But for everybody else, if the only time you can find to exercise is late at night, go ahead and do it. No excuses!
