I would define recharging your batteries as anything that lets you: catch up on sleep, (naps) let go of muscle tension, (massage, yoga) hangout with people you love or really like (socialize) laugh, and slow down your nervous system and heart rate through some sort of relaxation technique (including listening to relaxing music or reading a good book), and getting some form of aerobic exercise that makes you sweat.
But sometimes, it takes more than a quick relief from stress-inducing lifestyle, rather you'd need to be taken out of that place which most of the time gives you stress.
