Rather than naps, I can personally recommend yoga nidra, AKA non-sleep deep rest (NSDR) meditation. There's no effort involved. You just lie down and listen to an audio track. Lots of tracks available on YouTube and Spotify. With yoga nidra, you stay awake and get just as recharged from a good nap but without the risk of waking up groggy. It's a game changer.

If you're interested in the science behind it, Andrew Huberman often talks about it https://www.youtube.com/watch?v=1rSOn0PurVc
