As we Known human brain is a mysterious little ball of gray matter. After all these years, researchers are still baffled by many aspects of how and why it operates like it does. Scientists have been performing sleep and dream studies for decades now, and we still aren’t 100 percent sure about the function of sleep, or exactly how and why we dream.we should take at least 6-8 hrs sleep.
It’s not just a stab in the dark though there is some research to back up the ideas that dreams are tied to how we form memories. Studies indicate that as we’re learning new things in our waking hours, dreams increase while we sleep. Participants in a dream study who were taking a language course showed more dream activity than those who were not. In light of such studies, the idea that we use our dreams to sort through and convert short-term memories into long-term memories has gained some momentum in recent years.
We aren’t required to focus on anything during sleep, so our brains make very loose connections. It’s during sleep that the emotions of the day battle it out in our dream cycle. If something is weighing heavily on your mind during the day, chances are you might dream about it either specifically, or through obvious imagery.
There’s also a theory, definitely the least intriguing of the bunch, that dreams don’t really serve any function at all, that they’re just a pointless byproduct of the brain firing while we slumber. We know that the rear portion of our brain gets pretty active during REM sleep, when most dreaming occurs. Some think that it’s just the brain winding down for the night and that dreams are random and meaningless firings of the brain that we don’t have when we’re awake. The truth is, as long as the brain remains such a mystery, we probably won’t be able to pinpoint with absolute certainty exactly why we dream.
Now one question arise How many hours of sleep do you really need?
According to the latest info from the National Sleep Foundation, newborns need 14 to 17 hours of sleep in a 24-hour cycle.
We all know that a sleepless night can make us cranky in the morning. However, the other effects of sleep deprivation are far more serious than sleepy eyes and a short temper.
