Coffee eating before bedtime is generally considered not. You can go from tired to wired at a time when you need to put aspiration to put down, and in the near future it may be almost impossible to close the eye a little (excluded naps of coffee, which is an incredibly good needle to the thread and I do not think that anyone does it). But say you can fall asleep. How would this pre -coffee coffee affect the brain function?
It was researchers from the University of Montreal who recently tried to discover, and the results – because you may be surprised when they learned – they were less than ideal.
As reported Medical XpressThe study appeared in the recent issue of the magazine . In it, they examined how “caffeine can modify sleep and influence the return to the brain – both physical and cognitive – night.” Scientists noted the brain activity of 40 adults, while they slept using an electroencephalogram by two nights: one in which people received caffeine pills three hours and an hour before bedtime and one in which they received placebo.
Then, using “advanced statistical analysis and artificial intelligence in order to identify subtle changes in neuronal activity,” scientists found that caffeine consumption before bedtime increased the complexity of the brain signal and increased “critical” during sleep.
In general, criticality is a good thing. One of the authors of the study Karim Jerbi describes this as the Goldilocks brain state, which is “balanced between order and chaos.” It is the central ground in which brain activity is organized, and at the same time is pliant, enabling the brain “competent information processing, quick adaptation, learning and making decisions with agility.”
During the day, criticality is beneficial. Being more awake and alert are positive. But at night criticity stops the brain from rest and the possibility of relaxation and recovery.
Researchers also found that caffeine reduced Theta and Alfa waves, which are associated with a deep, regenerative sleep. Meanwhile, beta wave activity, associated with vigil, has been increased. These effects were more significant in younger people aged 20-27 than those 41-58. This suggests that younger people may be more susceptible to caffeine stimulating.
You probably don’t need the whole study to know that you don’t sleep so well when you drink coffee just before bedtime, but you still have it. At least now you know a little more study behind why your dream sucks.
