On a list of things that are good for recovery from jet lag, I reckon digging in your garden rates pretty high.
What doesn’t work well, I believe, is looking at a screen for hours on end, be it iPhone, iPad or Mac. Also leave out any inordinate amount of thinking, shopping or consumption of alcohol, even in what you deem modest amounts.
Walking on the beach is pretty good, especially smelling sea spray and hearing the ocean pounding. Sunshine in limited exposure will help reset your clock. Regular meals that you cook for yourself are of course nurturing.
But the best of all is home yoga practice, as much as you want, any time, even in the middle of the night: you can watch your breath, pacify your senses and relax your brain.
