There are health differences between being a lark that wakes up early, and a night owl that stays up late.

The study found that sleep habits affect our waistline, fertility, pain levels and even cancer risk.

It also affects your personality, with night owls being more likely to demonstrate dark personality traits like narcissism and deceitfulness.

Researchers interviewed more than 200 people about their personalities and sleeping habits, and found that early-rising larks always eat breakfast within half an hour of waking and that gets their metabolism going.
