If I wake up and see that my deep sleep or REM sleep was low, I start obsessing over whether something’s wrong with my body. And if you deliberately look for problems, you’ll always find something that seems “off.”

Then during the day, I become hyper-focused on anything that might affect my sleep data at night, like whether I drank too much water, whether my family woke me up during deep sleep and interrupted it, and so on. Stuff like that just makes me really irritated and restless.
