Most of us already know that sleeping is extremely important and every adult needs at least 7 – 9 hours of sleep on a daily basis to stay healthy and be productive. However, what most of us don’t know is the fact that sleep is linked directly to intelligence as well and we will try to understand that link with the help of the following points.
The Sleep Spindles
Sleep spindles are defined as neural oscillations of short durations which we experience during the REM sleep phase. These oscillations have been directly linked to intelligence quotient in people through studies that have been conducted recently. However, this is not exactly a new development since it was proposed earlier as well. Counting spindles might just give us an indication of the brain’s white matter integrity. As white matter basically interconnects all the information processing regions of the grey matter to each other, sleep spindles can also be considered to be directly responsible for controlling a person’s intellectual capabilities in certain aspects.
Reasoning and Sleep Spindles
It has been found that sleep spindles are directly related to cognitive performance and the boost in intelligence is not just an obvious effect of working with a rested brain. The oscillations positively affect the higher reasoning capabilities and fluid intelligence, while other facets of human intelligence such as the verbal aspects and the short-term memory remain unaffected by these spindles.
Women Benefit More from Long Sleeping Sessions
Everyone feels fresh after a good night’s sleep, but science is stating that women receive the most benefit from a long sleeping session during the night than men do. In other words, slow sleep spindles that take place when we are sleeping for long periods of time boost the IQ of women more than that of men.
Men Benefit Particularly from Short Naps
As far as intelligence is concerned, men benefit more from short-term naps than hours of sleep at a stretch. This doesn’t necessarily mean that men need any less sleep than women, but it does mean that men achieve the same level of IQ boost in a much shorter time and after the initial one-hundred minutes or so, the IQ benefits are insignificant to none. A hundred minutes of sleep (roughly the same time for which the REM phase of sleep lasts) at a time is therefore, the most beneficial to men, as far as boosting intelligence through sleeping is concerned. The male brain still needs many more hours to recuperate and regenerate just as the female brain though.
Ensuring Sound Sleep
As sleep spindles are generally not something that we can control yet, what we can control is the quality of the sleep that we manage to get every night. It might not always be a feasible option to get eight hours in, but it is important that the hours you do sleep are restful and for that, you will need to ensure that everything from the bedding you use to the ambient noise and light in your room are favorable for sleep. Visit Mattresstest.Com to find out which are the best mattresses, toppers, comforters, pillows and sheets available in the market right now and which ones would be just right for you to sleep peacefully. Buy a white noise machine or some ear plugs if loud noises nearby are keeping you awake and eye masks are always a great idea to keep things dark even in a well-lit room.
