Got a major decision to make?
Is your head full of noise?
Feeling stressed out about a particular issue?
Well, science says you should sleep on it. That’s right. It’s not just an old wives’ tale. Getting into bed and switching your brain off is the fastest and best way to help clear your head to make those decisions in the morning.
Why is this?
Think a few nights of tossing and turning aren’t enough to have an impact on your body? Think again. Unless you are getting the recommended 7-9 hours sleep per night then you could be putting your body into a sleep-deprived state, which means that all the effort you put into exercise and diet may end up being worthless.
Associated with the deepest levels of sleep, delta waves are something of an enigma. First identified in the 1900s neurophysicist William Grey Walter, who was inspired by Hans Berger’s electroencephalograph, or EEG machine which enabled the study of the brain during sleep. Walter constructed his own version of this machine with additional capabilities and ended up detecting the various brain waves observed during sleep.
During the awake stage, small and fast beta waves are produced. As the brain slows down for sleep it produces alpha waves until eventually, once in deep sleep, the brain produces delta waves.
Delta waves operate at a frequency range of between 0-4Hz, which is super slow. It is during this stage that the brain is fully unconscious, which makes delta waves tricky to study as no one can remember what happens during this part of the sleep cycle.
So, what are their benefits?
If your mother has ever nagged you about going to bed early to catch up on your beauty sleep, it turns out that she actually has a point.
Ever wake up feeling as though you’re still dreaming? We’ve all been there, that hazy morning moment when it’s difficult to tell the difference between reality and unconsciousness. Sometimes dreams can be so intense that they linger for a longer period and feel almost like real memories, which can be a weird sensation, especially when you’ve had some pretty strange dreams!
But, did you know that your dreams (even the strange ones) can actually influence you in your waking life?
