Why thinking hard makes people tired?

"New research shows that prolonged, intense cognitive work causes potentially toxic byproducts to build up in the part of the brain known as the prefrontal cortex". (ScitechDaily.com/Mental Fatigue Is No Illusion: Scientists Figure Out Why Thinking Hard Makes You Tired)

There is the possibility that we are tired during cognitive thinking for two reasons. The brain needs to reload its neurotransmitters. And if the temperature in the brain is rising too high. Cognitive operations turn difficult when the temperature rises. Especially when this happens inside the brain. 

The high temperature inside the brain causes the control of enzymes and other chemical processes to turn difficult. When neurons work hard their metabolism turns high level. The products of the metabolism of hard-working neurons also accumulate in the brain when a person thinks hard. 

And brain needs to decrease its temperature low enough that it can effectively continue its cognitive thinking process. So our brain requires sleep and breaks too. 

Getting tired is the mark that the brain needs a little break. And during that break called "sleep", they will decrease their temperature and reload neurotransmitters.  

Researchers found that when a person thinks the toxic byproducts are accumulating in the brain area called the "prefrontal cortex". That thing might be one of the reasons why we are getting tired while we are sleeping hard. But other things are involved in that process. When a person does cognitive work neurons in the brain are changing data. And during that process, they are using neurotransmitters. 

Whenever a chemical neurotransmitter crosses the synaptic border between neurons the enzyme destroys that neurotransmitter and frees the receptor in the neuron for the new neurotransmitter. So when a person thinks cognitively the neurotransmitters can go to a low level, and then the brains need to rest. During sleep, brains are reloading their neurotransmitters. The use of brains in cognitive actions requires energy. 

When the temperature in the brain goes up, cognitive performance goes down. High temperature makes it hard to control the neurotransmitters, proteins, and especially enzymes. When the temperature inside the brain turns too high the cognitive work turns too hard. And then brains get a signal that they must take a brake. That means brains will get a signal that they must go to sleep so that they can reload their neurotransmitters and make the temperature inside the brain get lower.

Energy clubs, where the sugar have replaced by aspartame can be deadly

One thing about aspartame is forgotten to say. That artificial sugar doesn't bring any energy in the cells, and here is one very nasty thing, what this chemical combination can do. In some concentrated doses, the sugar gives energy for velocity, and this is the very important thing in the ultra-sports like triathlon. Those energy bars give the energy very fast because they are filled with sugar. When this hydrocarbon goes to the body, the energy would be released immediately, when those molecules would go into the cell organs and mitochondria.


But if the sugar would be replaced by aspartame, there would be no energy in those "candies", and that could cause the extremely dangerous situation if the person thinks that those clubs would involve energy. Of course, the energy can be taken from the sports juice, but if there would be no sugar, would the hydrocarbon storage in the body ended. And if the juice would be replaced by water or some other "sugar-free" product, would that cause the death for that person. In theory would be possible that the person would die because of this kind of trick, and if that thing is made during the ultra-sports, the results could be deadly. If the carbon hydrate level in the person body would go too low, the result would be death.


And in this case, if the sportsman has taken amphetamine would the tiring cause death. This situation has seen on the dance floor, where persons have raved with amphetamine and the carbohydrates have been ended, the cells energy production would be ended, what causes death by coma, when the sugars and other carbon hydrates will be lost from the body. The most usual case of death during the sports, the person have taken amphetamine and forgot to eat sugars, what was caused the coma.

The story of the "Ghost tape 10" (OPERATION WANDERING SOUL)

We have all heard the story of the "Ghost tape 10", what was the record, what heard the horror movie. In this tape were messages, that if the Viet Cong fighters would not get home, their souls got in hell. This tape seemed to be useless against the Viet Cong, but sometimes it was used for some other use. In those river boat-operations in Mekong delta-area, this particular tape was used to cover other tapes. Those tapes were messages, where the Viet Cong-fighters were called to the beach to take the Soviet delivered equipment, and when those guerillas came, the gunboats and helicopters opened the fire.


Also, the "Ghost tape 10" were sometimes equipped with the subliminal messages, what have simultaneously repeated the messages, where the Viet Cong warriors claimed to be protected by the spirits, and also there were messages, that "The Viet Cong fighters must not care about enemy bullets and the training would make them bulletproof". That kind of loudspeakers claimed to drop near the training centers for making enemy's self-esteem twisted. And that might cause some losses for the enemy.


The third reason, why the "Ghost tape 10" was used, is that the beaches of the Mekong River were targeted high power ultra- and infrasound, what mission was to cause a headache for enemy troops. And also those sound weapon's mission was to deny the enemy from sleep, what made them tired, and then the CT-teams could kill them easily. But I don't know about the influence on those things. But the tired person is always the easier target.


The similar systems are planned to use in the hostage rescue missions. But this methodology has terrible ways to misuse it. It can use for provocating the riots, and that would give reason to call the riot control team to attack against those demonstrators. In this case, some mercenaries can target this kind of system against legal protesters, and then the using force against those people would be acceptable. In the Waco-siege from 1993, when the religious team committed suicide, one reason could be that after the David Koresh speaks some FBI agent said accidentally in the wrong moment words "do it" and then those people committed the suicide. Or in the worst scenarios, somebody has changed the tapes, for causing the massacre where 76 persons have died in the fire.
