My favorites recently are:
- reading - video games - programming side projects
Then there's the more productive options (see how bearish I am on my side projects?), like organizing (I'm trying to implement the Konmarie method) or cleaning. I like those things less, but they're still relaxing. Or I'll make something in bulk (yogurt, cheese, boiled eggs), which is also pretty relaxing (little to no mental effort).
I usually just find myself reading, especially just before bedtime.
Outside of that, just listening to music. I find it very relaxing to just sit and listen to one of Chopin's nocturnes or something of that ilk.
Unexpectedly for me another thing that is becoming relaxing as I grow older is to use my free time to stay on top of my household's chores. Just knowing I wont have the stress of having to rush them latter on because "oh fuck it's Monday morning and I don't have a clean shirt". Still far from perfect at it because procrastination run deep in me, but it's something I'm trying to slowly improve.
I talk to my wife.
I take an interesting online class.
I watch a movie.
I go surfing.
I talk to my parents.
I talk to my friends.
[0] for a lot of people switching off their devices and sitting down quietly for 15 min without knowing anything about meditation will already have effects.
Being outside on my own is pretty good in general. Walking or cycling are the defaults, but maybe count as exercise? I've recently started riding a motorbike and spin on some quiet-ish open roads can be pretty rewarding...
Other than that, there are plenty of inside options for that, like yoga (plenty of yoga series on YouTube), body weight fitness (pushups and whatnot, no equipment needed, though rings and/or pull-up bar are very handy), or aerobics (I count Just Dance games in that category), depending on what you're in to.
And of course afterwards you can light a candle and relax with a hot chocolate or some tea in the warm.
Why choose to live in a place like this if you don't enjoy it?
Or do cardio exercises by watching various YouTube channels? (This is how my friend keeps fit.)
you took excersize off the options - and I think taking a walk and tai chi fall in that, although some may say that's not the same.
I have found the best thing to help relax is dedicating 5 minutes to write - get stuff off the brain so you can relax and stop stressing it - pen and paper is fine, notepad, whatever. Write notes, jot ideas, a todo list, some mind mapping balloons.. sometimes some rhyming song lyrics to get stress off the brain and engage the heart in a healthy way.
After things are off the brain and into the paper or digital archive I find it's easier to relax in whatever situation is next.. sleep, hanging out with people, a book..
My cat even slept next to me for ~6trs until I got married.
Drawing, mostly doodles.
Read, I like reading people’s stories more than fantasy.
Meditation, it works.
Silence or Radio. Viberadio is one of my favorite.
Fiddle in green house.
Walk.
Look up old friends and give them a call.
