Minecraft gives me motion sickness?

Yea that is because the new Bed Rock edition has weird movements.

There are a few people who have had similar problems, try changing the FOV of the game, the field of view can help some people who get motion sickness. You can also disable head bobbing in the settings which might help

Yes, I also have this issue when playing 3D games. I mostly just reduce the amount of time I spend on such games.
