Why You May Feel Energized Despite Lack of Sleep

Sometimes, you might feel awake and energetic even if you haven't slept much.

This isn't usually a good thing, because your body needs sleep to work well.

Two doctors say it could be because your body releases adrenaline, like when you're excited.

Very rarely, some people have a gene that lets them function on less sleep.

Often, people get used to feeling tired without realizing it.

But not getting enough sleep can hurt your focus, mood, and health over time.

Lack of sleep is linked to health problems, so it's best to aim for 7-8 hours of quality sleep each night.

Be sure to avoid caffeine, alcohol and too much screen time before bed.
