What if you could make your sleep more efficient?

As a sleep scientist,

this is the question that has captivated me

for the past 10 years.

Because while the lightbulb and technology have brought about a world

of 24-hour work and productivity,

it has come at the cost

of our naturally occurring circadian rhythm

and our body's need for sleep.

The circadian rhythm dictates our energy level throughout the day,

and only recently we've been conducting a global experiment on this rhythm,

which is putting our sleep health

and ultimately our life quality in jeopardy.

Because of this,

we aren't getting the sleep we need,

with the average American sleeping a whole hour less

than they did in the 1940s.

For some reason,

we decided to wear it as a badge of honor

that we can get by on not enough sleep.

This all adds up to a real health crisis.
