Theres even a scientific explanation for why you long tosnooze all morning.

We’re supposed to sleep when its dark and be alert when its light.

Rousing to your alarm when it’s pitch black outside is fighting against nature.

Light is the cue that tells our brain and body that it’stime to wake up.

Here’s what they recommend.

Irregular schedules, on the other hand, keep your body guessing.

However, late nights are inevitableespecially on the weekends.

Ideally, you want to stay within an hour of your typical sleep and wake times.

If you go beyond that, just get back on track.

And try not to sleep past your usual wake-up time.

Also, avoid sleeping in too much later than your established wake time.

That leaves you groggier and makes getting out of bed even harder.

Its as if you’re telling yourself that its not time to wake up.

Its just time to lay in bed a little longer, explains Chamorro.

Try this: Set your alarm for a time that you could realistically get out of bed.

Get plenty of light in the A.M.

The sudden noise from your alarm can feel, well, alarming.

Once youre out of bed, don’t fumble around in the darkturn on the lights!

This will tell your circadian rhythm that it’s time to wake up, says Flynn Evans.

Brighter, bluer lighting is best because it mimics the natural cue that your body gets from the sun.

This doesnt need to be anything time-consuming or complicated.

Chamorro recommends journaling, listening to music, stretching, or having a warm beverage.

Does it matter when you have your gym session?

If you struggle with early workouts, Chamorro has a few tips to make it easier.

First, set your clothes out the night before so theres less to do in the morning.
