Why drives in a dream after a lunch?
That the stomach worked for conscience and could digest eaten at a table, its cages have to be most provided with oxygen and various nutrients. As result, after a nourishing lunch all blood of the person flows to a stomach. Respectively, passes blood through a brain slightly less. Cells of a human brain begin to do things by halves, functions of a brain "are turned off", and us begins to drive in a dream. If there is an opportunity, it is necessary to lie down and to have a rest really. During sleep our brain has a rest whereas heart and some other bodies do not stop for a minute. That is why, when we say that the person died of an old age, we mean that his vital motor "wore out".
When a stomach is filled by food to the full, it needs time for digestion of contents. And brain. Not only the tasty lunch, but also hard mental work, an irregular dream, long "communication" with the computer or the TV can tire and drive in a dream. Therefore at the first signal of a brain "I want to sleep!" it is necessary to put aside the interesting book and if there is an opportunity, a little bit to take a nap. Do not forget about the health and protect a brain – the head has to be freshen at any age!
