Sleep is a necessity and a ritual. We need it to rest our minds, but also to connect with our loved ones. Sleep is a time when our brains can scale back unimportant connections between neurons, removing memories or images that don't fit with others or aren't needed to make sense of the world. Researchers are still working to understand the mystery of sleep pressure and why we need to sleep.

What You'll Learn
Sleep is a need and a ritual
Sleep is both a need and a ritual. Our minds need rest, but they also need camaraderie and intimacy. We sleep with partners because we are affectionate beings. We want to discuss our days, our children, our household situations, and our plans for the future with our best friends. We want to know we're not alone.
But why do we need to sleep? There are still many unknowns, but researchers are working to get to the bottom of sleep pressure. One theory is that sleep is when our brains get rid of unimportant memories or images that don't fit with others or don't need to be used to make sense of the world. Sleep-inducing substances may come from the process of making new connections between neurons. Another theory is that sleep is when the brain does a "cleanup" of sorts, removing memories or images that are no longer needed.

Sleep helps us to feel less alone
Sleep is also a time when our brains can get rid of the memories that don't fit with the others or don't need to be used to make sense of the world. Sleep researchers Chiara Cirelli and Giulio Tononi suggest that since making new connections, or synapses, is what our brains do when we are awake, maybe what they do during sleep is scale back the unimportant ones.
Sleep is a need and a ritual. It is a time when we can feel less alone and more connected to those we love. It is a time when our brains can rest and recharge, and when we can strengthen our relationships and feel supported.

Sleep is a time for our brains to 'clean up'
Sleep is a time for our brains to clean up. Sleep is a need and a ritual. We sleep together because we are affectionate beings. Our minds need rest, but they also need camaraderie and intimacy. We want to remove the cloaks we've donned to face the world while lying next to our best friends.
There are still many unknowns about how sleep works, but researchers are working to get to the bottom of sleep pressure. Sleep-inducing substances may come from the process of making new connections between neurons. Chiara Cirelli and Giulio Tononi, sleep researchers at the University of Wisconsin, suggest that since making these connections, or synapses, is what our brains do when we are awake, maybe what they do during sleep is scale back the unimportant ones, removing the memories or images that don’t fit with the others, or don’t need to be used to make sense of the world. “Sleep is a way of getting rid of the memories in a way that is good for the brain,” Tononi speculates. Another group has discovered a protein that enters little-used synapses to cause their destruction, and one of the times it can do this is when adenosine levels are high.

Sleep helps us to get rid of unimportant memories
Chiara Cirelli and Giulio Tononi, sleep researchers at the University of Wisconsin, suggest that sleep is when our brains get rid of unimportant memories in a way that is beneficial for the brain. Tononi speculates that "sleep is a way of getting rid of the memories in a way that is good for the brain".
Supporting this theory, another group of researchers has discovered a protein that enters little-used synapses to cause their destruction. This process can occur when adenosine levels are high.
While there are still many unknowns about how this process works, researchers are actively investigating the role of sleep in memory consolidation and synaptic scaling.
