5 simple 'body clock hacks' that help you fall asleep fast and wake up with more energy

A woman sits on the edge of her bed facing the window, stretching in the morning light shortly after waking up.

We all have a natural 24-hour body clock that wakes us up in the morning and makes us feel sleepy at night. Basically, it makes sure that we're following the correct sleep-wake cycle so we can get enough rest and feel energized during the day.

However, this internal clock (also known as a circadian rhythm) can sometimes experience 'glitches'. Modern life can disrupt circadian rhythm, throwing our sleep-wake cycles out of whack, making it harder to fall asleep and wake up feeling refreshed.
