Do we dream when we’re asleep. In fact, it has a lot to do with the ambient temperature. Let’s first talk about something that no one can guess right at once: “melanocyte aggregation hormone neurons” (MCH).
This neuron, which is responsible for dreaming and forgetting, works only during the rapid eye movement period after you fall asleep. Scientists have found that when the surrounding temperature becomes comfortable, MCH neurons will be activated and the dream time will be prolonged. On the contrary, when the surrounding temperature is too hot or too cold, the neuron will start to strike, making you unable to dream. This may be because both brain activation and body temperature maintenance are very energy consuming for the body, and there is no way to take care of them at the same time. Based on the principle of “do not hurt the body first, and then pay attention to the effect”, the task of maintaining body temperature must be prior to that of using brain (too hot and too cold is really death, too stupid can’t).
Therefore, when it is too hot and cold, not only can you not think, but also can’t dream after sleeping. So, ah, you must not stop people from turning on the air conditioner, because in fact, this is depriving them of the right to dream!
