My view on insomnia: it is inevitable when insomnia lasts for how long. As long as it exists, it has its reasons and reasons. It is the result of various coincidences. Sleep depends on the brain, and all kinds of information are transmitted to the brain. This is determined by its instinct. People are not robots. We can decide when to deal with it. Our brains, like our hearts, never stop working. It's normal to think during the day and dream at night. If the brain encounters a lot of information or troublesome things, it will take up our rest time to continue thinking and activities, leading to insomnia. This is beyond our subjective control. Actually, this is a normal phenomenon. Don't be afraid, just let nature take its course. At that time, I couldn't even think about insomnia. It is best not to take medicine, because taking medicine will break a person's sleep balance and lead to dependence.
