I'm sure it's frustrating to hear over and over again. But generalized advice doesn't and can't apply to everyone. Many people have extremely poor habits around sleep, and don't appreciate or dismiss the importance of it.

Maybe there's some underlying pathology in more cases than you will ever see acknowledged in traditional medical research (e.g. person is mildly addicted to being on a computer screen, or person has breathing problems that make it hard to sleep soundly). But that still doesn't make it bad advice on average and in general!
