That is because people tend to stay home where is air-conditioned to avoid heat stroke or dehydration. If you tend to stay home, you don’t walk and talk very much.
No walking and no talking damage the brain during summer.
If you don’t do aftercare of the brain, there is a risk that your memory falls or your thinking becomes slower.
Why do no walking and no talking give bad effects to the brain?
Using the muscles of the legs promotes the blood circulation to the brain.
When you talk, you use the frontal lobe where speaks words and the temporal lobe where understands words so if you don’t use them, the damage to the brain increases.
If so, does talking with your family prevent the damage to the brain?
Talking with your family doesn’t decrease the damage to the brain. When you talk with your family, you are not careful to speak. That means you don’t need to care about whether or not the topic is interesting, or whether or not how to speak is rude. So the brain is not used so much at that time.
Therefore, to reduce the damage to the brain, it is effective to talk with people other than the family.
What is the damage to the brain stored during summer?
If the nerve cells in the brain are personal computers and the nerve fibers which connect the nerve cells are cables, the damage due to no walking and no talking decrease the number of the cables. The decrease of the cables causes the order of the brain difficult to be transmitted. (Fig. 1)
The decrease of the cables for memory causes loss of memory.
The decrease of the cables for motion causes stumbling.
We make various judgements when we walk. If the cable becomes thin, the transmitting speed becomes slow when we lift our legs, so we can’t lift the legs sufficiently and then we fall down.
The decrease of the cables for reason causes short-temper.
The frontal lobe of the brain plays a role to control emotions. The decrease of the cables to the frontal lobes causes inability of controlling emotions sufficiently.
Is it possible to recover the cables once being cut?
The nerve cells (personal computers) can’t be increased.
The nerve fibers (cables) can be increased and can be connected to other nerve cells (personal computers).
What is the aftercare method?
A hint of the method is breathing in and out frequently, probing your memory.
That is singing in Karaoke.
While you are singing in Karaoke, various parts of the brain are used including the cables connecting personal computers.
Tempo, Interval: The frontal lobe
Memorizing lyrics: Memory area in the temporal lobe
Breather: Motor area
Also playing musical instruments increases the cables.
For example, the corpus callosum (a bundle of cables) of a pianist whose left and right hands move differently is developed thickly.
Another aftercare method for the brain:
The method to improve the function of the hippocampus which controls memory is 10 minutes fast walking a day.
The protein that activates hippocampus is produced by light aerobic exercise.
