Do we dream when we fall asleep. In fact, it has a lot to do with the surrounding environment temperature. We must first talk about something that no one can guess right at once: “Melanin Concentrating Hormone Neurons” (MCH for short).
This neuron responsible for dreaming and forgetting only works during the rapid eye movement period after you fall asleep. Scientists have found that when the surrounding temperature becomes comfortable, the MCH neuron will be activated and prolong the dreaming time. On the contrary, when the surrounding temperature is too hot or too cold, this neuron will start to strike, making you unable to dream. This may be because using the brain and maintaining the body temperature are both energy-consuming for the body, and there is no way to take care of it at the same time. However, based on the principle of not hurting the body first, and then stressing the effect, the task of maintaining body temperature must take priority over using the brain to be too hot and too cold. It’s really going to die.
