Daily is the best.

This system is really about...

And you'll see that even for the effect on depression, it's about multiple days.

So you don't have to worry if you missed it one day, stay longer if you want.

But if you're in a hurry and you want to do other stuff, that's a great recommendation.

And you saw this during the pandemic.

A lot of people mentioned that their sleep-wake cycle suffered a lot.

Because if you're not going out and if you're staying at home and you don't have big windows and you're waking late, waking up late, and then you're using very bright light till late at night, your body's going to shift.

And now your day is going to start instead of like really when the sun comes up, let's say at six o'clock in the morning,

your day is going to start at 11 o'clock in the morning.

That's what your body is going to think is the beginning of the day.

So then you're not going to be able to sleep at 10 o'clock at night because now that's really, for your body, is completely different timing.

So there is great data on this, and there is a couple of things that complicate this.

The first is

The people who usually are late.

What do you mean?

People that wake up late and go to sleep late?

Go to sleep late and wake up late.

They have an overwhelmingly higher level of depression because human notice that people who go to sleep early and wake up early, they do better in life.

They notice that.
