Headache and Nausea using iPhone 11

I bought my iPhone on Friday and every time I use it I start to feel headache and a bit of nausea. The more I use it the more the feeling increase. I already tried every feature that should be useful: I reduced the movements, reduced the white colours, tried to use the night shift, turned off Face ID, but nothing. I’m still having these problems. I’m thinking about giving it back.

It’s not my first apple device. I’ve used iPhone 4, 6s, IPad 4, various Macs and I’ve never had these problems before. Has something like this happened to somebody else?
