That just is a rule that you can make for yourselves.

All of those things might help a bit.

I don't want to overdo the sleep hygiene piece because I also know there are some great sleepers out there who have pretty poor sort of sleep habits.

They're all part of this picture of positive sleep health.

I think if there was anything to add to that, it's just that I would love people to believe that sleep is important, but also to believe that they are good sleepers.

A lot of what I do is help people build confidence.

So if you do those habits, what happens is that you build confidence that you are going to sleep well.

So that helps to ease the anxiety.

If you're someone who has been anxious about sleep in the past, the danger of this advice is that it's too rigid and that if you haven't had...

15 minutes of daylight within an hour of waking up, you start to get anxious.

If your phone's accidentally gone into the bedroom, then you might have a terrible night's sleep.

So these are guidelines.

They are recommendations.

They are not strict rules.

So there was a paper that was published, I think just a month or two ago on this, and it was actually a survey.

So this was a Canadian study and over a thousand students who got credit for taking part in the survey.

And they asked them about the foods they ate and whether the people thought they influenced their sleep and their dreams.

And out of a thousand people, I think only 1% suggested that dairy influenced their dreams.

The study suggested that that population were more likely to be lactose intolerant.

So of course, if you're eating something that really doesn't agree with you, it may well disrupt your sleep.
