How Long Does It Take to Fall Asleep?

On average, it takes seven minutes to fall asleep. Contrary to popular belief, sleep is not a time where the body shuts down to rest. Some types of brain activity increase, and some types of hormone production increase as well. There also is no evidence that any major organs shut down, though the metabolic rate might slow down a bit.

Counting sheep facts:

  • There are more than 70 known sleep disorders.

  • In the United States, about 250,000 people suffer from narcolepsy, a disorder that causes extreme daytime fatigue and may cause a person to suddenly fall asleep at inappropriate times, such as as work or driving a car. More than 3 million people worldwide suffer from the disorder.

  • Babies fall asleep directly into REM sleep.

  • On average, people have about 1,460 dreams per year.

  • The human sleep cycle averages about 90 to 110 minutes.

  • The brown bat sleeps the most hours per day on average: 19.9 hours.

  • The giraffe sleeps the least number of hours per day, clocking just 1.9 hours on average.

I have some kind of unknown disorder, but my parents deny it and won't take me to a doctor to get me checked out. They use the excuse that my TV is on.

It takes me four hours after lying down and closing my eyes to finally fall asleep and I can be as tired as I want, but I won't fall asleep, because when I close my eyes I think and think and think, I can't stop. My mind runs itself and it drives me insane until I have to just watch TV or play my games to stop thinking so much.
