It is a widespread evil, but due to increased interest in the subject and the latest advances in the scientific field, it is finally possible to decipher some facts. Talking about an\u00a0insomnia epidemic<\/a>\u00a0is no longer a cautionary tale. The number of people suffering from this disorder increases every single day.<\/p>\n<\/div>\n

\n

But how can a night of \u201ctossing and turning\u201d be avoided?<\/strong><\/p>\n

Pressured to find new and better solutions, scientists carry out more and more studies about sleep disorders and\u00a0our sleep cycle,<\/strong>\u00a0every day. But in order to really understand the science of sleep, we need to break it down.<\/p>\n<\/div>\n

\n

Until the mid-20th century, people believed that\u00a0during the sleep cycle<\/strong>\u00a0the brain would shut down completely to recover. Nowadays, we know that\u00a0we sleep to save energy, maintain our physical body and cement memory.<\/strong><\/p>\n<\/div>\n

What are the physical effects of a sleepless night?<\/strong><\/h3>\n<\/div>\n
\n

During a study carrying on by the University of Surrey, UK, in which scientists kept people awake for 29 hours. Later tests showed the number of white cells had increased as if they were fighting off infection.<\/p>\n<\/div>\n

\n

Sleep deprivation leads our body to release hormones like cortisol and adrenaline, which make our blood pressure rise and you might have a sudden urge to eat carbs because your metabolism is out of sync.<\/p>\n<\/div>\n

\n

The student Randy Gardner holds the record of being awake for the longest time. In 1965, he stayed up for a total of 264 hours, that\u2019s 11 days. As his\u00a0sleep cycle<\/strong>\u00a0was more and more affected, Randy began to lose the ability to think, paranoia settled in and he started to see things that weren\u2019t there.<\/p>\n<\/div>\n

\n

At the end of the experiment, he slept for 14 hours straight. There were no signs of consequences.<\/p>\n<\/div>\n

The sleep cycle: what you need to know<\/strong><\/h3>\n<\/div>\n
\n

Nowadays, we know that our\u00a0sleep cycle<\/strong>\u00a0has 4 different stages. The most interesting\u00a0sleep cycle<\/strong>\u00a0stage is the last stage \u2013 REM sleeping or Rapid Eye Movement when your brain activity increases, and dreams happen. You can see what happens to your body as you move through the different\u00a0sleep cycle<\/strong> stages, in the picture below:<\/p>\n

\n

Have you experienced living a moment during the day and that memory coming back exaggerated or distorted over and over in your dreams? It happens to everyone, it\u2019s our memory working overtime while you sleep.<\/p>\n<\/div>\n

\n

Why are memories sometimes distorted, spiced up with fantasies or with things that have never happened?<\/strong>\u00a0There is a theory for that:\u00a0 the Synaptic Homeostasis Hypothesis (SHY). It seems complicated but it isn\u2019t.\u00a0 It so happens that during sleep, the brain undoes some neurologic connexions, that is, it erases memories.<\/p>\n<\/div>\n

\n<\/div>\n
\n

The body releases acid gamma-aminobutyric, a substance that weakens relations between neurons. Its goal is to free space and cerebral capacity so you can pursue the ability to learn new things.<\/p>\n<\/div>\n

\n

During the\u00a0sleep cycle,<\/strong>\u00a0we need to determine which memories are the least important so the brain verifies their connexion with other information previously stored in your mind.<\/p>\n<\/div>\n

\n

This \u201ccleaning\u201d of the memory happens just before dreams<\/strong>. So, it\u2019s possible that when dreaming begins, the brain is still under the influence of memory defragmentation. That may explain the level of fantasy in dreams, but there\u2019s no evidence of that.<\/p>\n<\/div>\n

\n

The connection between memory and sleep<\/strong><\/h3>\n<\/div>\n
\n

However, the connection between sleep, memory, and learning is highly acknowledged. Several studies about our\u00a0sleep cycle<\/strong>\u00a0show that our ability level to learn is higher in the morning, right after we wake up.<\/p>\n<\/div>\n

\n

From another\u00a0sleep cycle<\/strong>\u00a0study, it was concluded that external stimuli during sleep can influence our learning. Psychologist Ken Paller led an experience where 50 volunteers went straight to sleep after seeing a sequence of images and sound.<\/p>\n<\/div>\n

\n

During sleep, half of them received a sound stimulus in the third stage of our\u00a0sleep cycle<\/strong>\u00a0(NREM), the same sound associated with the images. On the following day, the volunteers took a memory test and the ones exposed to the sound during sleep were able to remember more images in the correct order.<\/p>\n<\/div>\n

\n

We know it\u2019s not possible to learn new things when sleeping.
\nHowever sleep can strengthen the memory of something we\u2019ve learned awake.<\/strong><\/h4>\n<\/div>\n
