I think I wrote this before too but every summer, I find that there are 2 things that I cannot find people to agree with in the United States. It is almost common knowledge in Japan but not here.
1. There is AC sickness
In Japan, a lots of people suffer from this. I mean... it's almost like a cold, nothing major but people feel dull, tired, less appetite, etc. I tried to explain this in English but so far people don't believe me...! it's true...! Here is Japanese website that says it... google translator translate it a little odd but here.
"The air conditioning sickness, the symptoms were more common in elderly people and there is no strength. However, in recent years has increased young people should be full of energy. It is considered unhealthy lifestyle are involved.
Hot summer is the season even easier just ill. The urban heat island effect increases in tropical nights sleepless, more and more people get enough sleep.Sometimes you fall in appetite because of the heat. On the other hand, full of summer fun events. Even though it was a touch of summer, or late at night just to or excessively or binge drinking a beer. And catch up on sleep on weekends.
These irregular eating and living, puts a heavy burden to the autonomic nervous system, increases the risk of catching an autonomic imbalance and other air conditioning sickness. To arrange an autonomic nerve, time for bed, wake up and you eat a certain time, it is important to live a regular life as possible.
The major cause another upset the autonomic nervous system function, and stress. We like to stress, such as Tamenai good change of pace. And smoking, nicotine blood vessels to constrict, making it easier cooling of the body. Smoking is also why, this is one of the most important disease prevention measure air-conditioning."
2. It is not good to sleep your fan breeze on directly to you
This is because it can deprive your body temperature if you have it on for a long time. I know a few friends who had a fan on and their face got numb. When they went to doctor, they told them not to have fans directly on you.
毎年夏になると、アメリカ人と口論になりますが、アメリカには冷房病ってないみたい。だから、冷房が体に悪いと言う話が通じない!みんな皮下脂肪多いから大丈夫なのかなぁ、、、。
