There are 5 distinct sleep stages, with REM sleep being one of them. Most people fall into the REM sleep stage nightly, and many experience it four or five times each night.
What is REM Sleep?
REM stands for rapid eye movement, and is characterized by random, fast-darting movements of the eyes. While the amount of time you spend in REM sleep varies depending on your age, most adults spend up to 25 percent of their total sleep time in REM sleep. On the other hand, newborns spend more than 75 percent of their sleep time in REM sleep.
Happiness may not come from your family, friends, or wealth, at least according to a new study. Rather, it comes from a peptide.
Led by the University of California Los Angeles, an international team of researchers has linked levels of hypocretin (a human peptide and neurotransmitter) to happiness. They found that the levels of hypocretin soared when we are happy, and also decreased when we are sad.
When people are sleep deprived, they tend to eat more, which causes them to gain weight. This was the finding of a fresh study conducted at the University of Colorado, Boulder that was published online in Proceedings of National Academy of Sciences journal.
“Just getting less sleep, by itself, is not going to lead to weight gain,” lead study author Kenneth Wright, director of CU-Boulder’s Sleep and Chronobiology Laboratory said. “But when people get insufficient sleep, it leads them to eat more than they actually need,” Wright noted.
Sleep Researchers at the University of Pennsylvania’s Perelman School of Medicine studied the dietary divergences among individuals with diverse sleep patterns. What they found in a diet and sleep study, as published in the journal Appetite, was striking.
An increasing amount of sleep research is being conducted on a daily basis, and some of it is quite intriguing. To that end, we’re starting a new series on the PlushBeds Blog on “sleep studies”. You can expect to see posts on new sleep studies periodically as fascinating new sleep research comes out.
Seals Sleep With Half of Their Brain
A new sleep study published online in the Journal of Neuroscience has identified chemicals in a seal’s brain that enable them to sleep with half of their brain at a time. In other words, seals have the ability to be awake and asleep simultaneously! How amazing is that?
When you sleep every night, without you even realizing it, your brain goes through five distinct sleep phases or stages: phases 1,2,3,4, and Rapid Eye Movement (REM) sleep. You complete one full sleep cycle when you pass through all five stages of sleep. Passing through these stages usually takes approximately 90 minutes, according to the National Sleep Foundation. Let’s take a look at each individual stage, shall we?
Getting a good night’s sleep is extremely challenging for many people around the world. One method more and more people are turning to for capturing that all-important sleep is listening to binaural beats. While it may sound like some far-fetched music from a foreign land, there is science to these sounds that alter brain wave activity and make sleep possible.
There’s been a host of discussion about various factors that impact a person’s quality of sleep, including the amount of light in the room, foods eaten,bedroom colors, mattress firmness, and type of mattress. Let’s add another one to the list: your bedroom’s air temperature. The connection between sleep, body temperature, and air temperature has been debated by more than one expert in the field.
You may have heard about the idea of sleep learning from books, magazines, the internet, or television, but may have raised your eyebrows with the thought that it actually worked. While the concept of sleep learning is far from new, a new study has found that it might actually work.
When you’re sick, the one thing your body needs more than anything else is often the one thing that feels the most elusive – sleep. You want it. You need it. But the symptoms of your cold or flu seem to make it impossible.
According to WebMD sleep expert Michael Breus, PhD, “It’s true that many cold and flu symptoms seem to get worse at night, and they can interfere with sleep just at the critical time when your body needs rest the most.” But, why is this the case and what can you do to increase your ability to sleep when you’re sick?
