Well, the mechanisms aren't clear, but it has been established very extensively that exercise can promote sleep.
I was involved with a study that actually compared exercise with sleeping pills.
And we found that chronically, exercise actually had very similar effects.
But what was particularly surprising was even a single session of exercise was as good as sleeping pills.
So, you know, you think someone, they take a sleeping pill on that night, they're certainly going to sleep better.
But exercise was similar, had similar effects.
How it does, you know, it might be partly, well, maybe partly by reducing stress and anxiety.
It might be partly due to light exposure.
People get outside and the sun exposure is good.
It might, yeah, just, it's a timeout from stressors that cause stress.
And maybe through a better circadian synchronization.
We know that exercise can help synchronize the body clock.
I mean, just because it's been shown so many times.
But, you know, that's a separate question about people want to know what happens that day.
But then also it's important to know that if you exercise regularly, there's good evidence that that can chronically change.
Well, there's certainly more evidence that aerobic exercise and resistance exercise promote sleep.
There's less evidence for Tai Chi and yoga and so on, but there's evidence maybe not quite as extensive as with aerobic exercise and resistance exercise.
Yeah, John, I would say in the daytime, one myth about exercise that a lot of people think is that it will disturb your sleep if you exercise at night.
Certainly within a few hours of bedtime, but
That probably is the case for some people, but there's been multiple investigations of this.
