Sleep: A Biological Necessity (02:49)

FREE PREVIEW

When people sleep, their brains remain active; it is a biological necessity, shared by all animals. Those who are most vulnerable while sleeping do less of it. Some sea mammals have adaptations allowing for partial sleep states.

Neuroscience and Sleep (07:11)

Neurons communicate by sending neurotransmitters over synapses; these signals can be detected by electroencephalogram. Studies show how brainwaves shift from Slow Wave Sleep to Rapid Eye Movement continuously, driving a genetically dictated program.

Researching the Sleepless (08:59)

Sleep is a multibillion-dollar industry. Podcaster Drew Ackerman helps subscribers fall asleep by being boring. At the Netherlands Institute for Neuroscience, Eus Van Someren uses high tech electrode nets to record insomniac brain activity; his findings show they are less likely to recover from emotional distress.

Sleep and Trauma (04:58)

Researchers examine the impact of sleep on those with Post Traumatic Stress Disorder. They apply findings to firefighter experiments intended to prevent nightmares. Trauma can make REM sleep hyperactive but can be mitigated by delaying sleep after stress.

Sleep and Memory (10:47)

A 1924 Cornell University study indicates sleep impacts memory. A University of Arizona experiment reveals that toddlers napping after learning information can recall it more consistently. Brains flush cellular waste during Slow Wave Sleep. Neurologist Phyllis Zee researches older adults.

Sleep and Modern Life (08:42)

Americans lose sleep to technology; industrialized nations have determined sleep is unnecessary. Sleep deprivation studies reveal that insomniacs doze for brief periods. Research on light deprivation proves that the circadian clock controls Melatonin release. Firefighter Matt Reinhold confirms sleep quality is as important as quantity.

Importance of Sleep (06:05)

Sleeplessness causes cognitive and memory deficits, but some individuals are more resistant. Neurobiologist Ketema Paul studies the BMAL1 gene, experimenting with its’ impact on sleep deprivation recovery. Sleep is essential for brain function, mental health, memory, and well-being.

Description

Virtually every animal sleeps. But why? Why do we need to spend nearly a third of our lives in such a defenseless state? Scientists are peering more deeply into the sleeping brain than ever before, discovering just how powerful sleep can be, playing a role in everything from memory retention and emotional regulation to removing waste from our brains. So why are we getting so little of it?
