Sleeping on recovery days

[RickG16]

Having hit the big 4-0 and still playing a lot of sports I'm realising the importance of rest days....

 

The problem is when I take a day off sport or gym, even with a bit of walking factored in, I struggle getting to sleep. But if I do a bit of gym or play sport, it ceases to be a rest day....

 

Any tips on how to sleep better during these recovery days. If I did a 10 minute run just to sweat, would this defeat the purpose?

 

Cheers
