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?
Why is it that when you get back to work after lunch, you could put your head down on your desk and fall fast asleep? And that same feeling hits us double-time after Thanksgiving dinner? Aren’t calories supposed to provide energy? So, why do they make us sleepy? Here’s some science behind this counter-intuitive sleepy after eating phenomenon.
The Science Behind the Siesta
While many think that it’s the tryptophan in the turkey bird, our healthy living friends at HuffPost tell us that there are other foods like eggs and cheese that promote the same sleepiness effect.
It’s comes as no surprise that the physical discomfort and hormonal changes associated with pregnancy can wreak havoc on a woman’s quality of sleep. And if you are experiencing disturbed sleep during pregnancy you’re not alone; 78 percent of women indicated problems sleeping during pregnancy in a National Sleep Foundation (NSF) poll. Moreover, while your body is growing your bundle of joy, you’re likely to have sleep changes during all three trimesters of your pregnancy, according to the NSF.
Just as our hair will likely turn grey and wrinkles will probably adorn our faces, as we age many of us can expect to encounter sleep changes.
These sleep and aging changes can result in waking up throughout the night, becoming sleepy earlier, and awakening earlier than we used to.
Sleep and Aging Statistics
As many as 50 percent of seniors experience some sort of sleep disturbance as they embark on their golden years. And according to the National Institute of Aging, a good number of seniors are not getting enough sleep. One of the reasons that many seniors are sleep deprived is in their trouble in falling asleep. More than a third of women and 13 percent of men reported taking more than an half an hour (30 minutes) to fall asleep (sleep latency), according to a study the institute cited.

While many people around the world scoff at the idea of premonition dreams, many people are thought to have had them—even the skeptics. The thing to keep in mind about premonition dreams is that they aren’t always the foretelling of bad things to happen in your life. Sometimes, they bring good news. Unfortunately, those dreams are rarely credited for the premonitions of good fortune they really are.
The science behind dreams is complex, and certainly not clear-cut. While there are the believers that think our dreams — including premonition dreams — mean something, there are other naysayers who don’t.
What is a Premonition Dream?
How do you know a dream you’re having is a premonition dream? What makes it different from other dreams you have? Sometimes a dream is just a dream, right? Premonition dreams are certainly different from lucid dreams, which is the name of the type of dream coined by Frederick van Eeden, and describes the act of dreaming while knowing you are dreaming. However, when dreams foretell a future event, warn of a major health crisis or death (like they did in the Sandra Bullock 2007 film “Premonition“), seem abnormally vivid, recurs over several nights, is shared by others, or occurs in combination with physical symptoms, the chances are that it’s a premonition dream.
