Rather than rage and losing your temper why don't you look at any losses from a different point of view, look at them as learning experiences to make you a better player. You lost because you made mistakes, find out what they were and your losses should start to drop. If you lose, you lose, it's no big deal. Everyone loses from time to time but smashing your house up doesn't help anyone because you've still got to clean the mess up afterwards.
How to manage loss rage?

Whenever you lose a game, stop playing and analyse your lost game thoroughly so as to learn from your mistakes and to channel the negative emotions of the loss towards a positive goal: improving.

Break something (just not your phone, or the house, etc.)-----that's if you *must* channel said rage aggressively...alternatively, just take a break from chess and do something else for a while...then resume playing; play until you win. Then stop for a while. Then resume again.
I have heard rumors and whispers of rage, but of course wouldnt know anything about it.
I mean if a person all of a sudden plays better, after a trouncing slices and dices....after a beatdown plays like a pro...after looking like a loser, then has blood dripping from their mouth like a bezerker....this hulk-like transformation, being stuff that legends are made of.

Smash your ego and grow up. It's a big world out there and you are just a drop in the ocean, not the king of the world. You may and will lose, get use to it.
Practically you can take a break and do other things for a while. You can practise this mantra if it helps "People do mistakes all the time, and I'm no exception"

I'm kind of envious that the biggest thing you need to worry about in your life is losing a chess game.

Perspective is often lost when dealing with emotions. So yes at that point there's probably no greater issue.
After you involve yourself totally in an activity, always good to take a step back to keep the big picture.

If you spend time telling people in forums that they are a cupcake because they show emotion when they lose a game of chess, maybe it’s you who needs to get a life.

Buy a heavy bag or a wavemaster. That way you can take out your frustrations while getting a work out at the same time. If you lose a lot at least you'll get ripped.

Go give your parents crap about not teaching you what games are, and how they are not important, or an indicator of your self worth. You should have learned that by preschool ...
If your parents are the ones actually pushing you, then quit chess. You can always get back into it later on your own terms.

i knew a guy that would do 10 pushups after every missed free throw... 🤔
Good way to build a healty body. And the pain.. could be a great instructor. It was proven that people can remember more under pain and pressure.

still, better to understand your negative feelings & rise above them than try to channel them positively in my opinion. 🙂

One should see losses as experience in chess. People learn by doing mistakes. So it is an indicator of learning.. But however we all were taught making mistakes was bad, we got punished for that in our education system.
How is it possible to manage rage after loosing a game? What kind of stress relieving methods do you recommend? What books do you recommend?
What is the point where you realize that chess might bot be advisable (for ex smashing the house after defeats)
Thanks
