What it means when you are suddenly jerked awake when falling asleep

You are all settled in for the night, cozy and warm in your bed.   You start to drift off to dreamland, and all of a sudden you are falling or something hits you in the face. Whatever it is, you are suddenly startled awake with a jolt.

This strange sensation actually occurs on a regular basis to many people, and scientists have finally figured out what it means.

This process of being startled awake is referred to as the “hypnic jerk.” Although everyone has their own unique experiences with the hypnic jerk and describe the feeling a little differently, it is often explained as the feeling of falling.

The hypnic jerk is most often seen when a person falls asleep rapidly during or after an exhaustive state. When the body is exhausted, the brain can process the stages of sleep too quickly. This confuses the brain into thinking that the body and its major systems are failing. The brain then responds by jolting you awake with a burst of chemicals and then builds a dream designed to wake you up.

Check out this video from Discovery News to better understand the hypnic jerk and why we twitch.

The Story of Stuff

Released in 2007, The Story of Stuff takes a closer look at the linear pattern of our economy. From our constant reaping of the planet’s finite resources to the addition of toxic chemicals to our products and our overwhelming transition to identifying ourselves as consumers, this unsustainable system cannot and will not last forever.

This video illustrates the current flow of our economy and the role that government, corporations, and individual consumers play in the “big picture.” It points out the problems with our current linear model, and the possibility of change to a more cyclical model based on people coming together to make a difference.

Take Sleep Seriously!

Meet Russell Foster, a circadian neuroscientist who studies sleep patterns in the brain. In the following video, he speaks about a range of topics relating to the importance of sleep.

He first describes three theories on the main function of sleep, as well as which theory he subscribes to. He then discusses what happens to a person (and the person’s brain) when sleep is lacking, as well as ideas about how to improve sleep quality and duration. Foster debunks some common myths and misconceptions about sleep, then speaks about the correlation between mental health and sleep disruption. He urges people to take sleep more seriously and realize the huge role that it plays in making us happy and healthy.
