You think it’s not a big deal to get up once or twice? The reality is, every time you wake up, you violently interrupt your sleep cycle. It’s a bit like cutting a movie every ten minutes: hard to keep up, right?

You wake up more tired ,
You are less focused and more irritable,
You impair your ability to memorize.
And this circle can take place without you really being aware of it.
Simple steps to get more continuous sleep
