Yeah a lot of people say take the TV out of the bedroom. But I'll be damned if putting a show on doesn't put me out. I know people say the light is bad, screens are bad blah blah blah. But TBH I think it's the content that is keeping people up, doomscrolling on phones, reading news, etc. I think as long as you turn off the lights when you pass out, that's all you need to do. Don't sit there and binge watch until 2am, either.
And then I look back at my dad. He'd watch TV and fall asleep in his chair every night. The man slept like a log every night. He never used an alarm, he just woke up when he needed to, but wasn't late for work or anything like that. Never seen anybody with better sleep hygiene. But he also had a very physical job.
