To what extent does insomnia reduce productivity? Is it just slightly less productive, or does it make it harder to keep working? This begins with a detailed analysis of the nature of insomnia. Insomnia means that you want to sleep beautifully in a quiet and undisturbed environment, but you cannot fall asleep as you wish, or you fall asleep but sleep shallowly, dreamy, wake up from time to time, wake up and find it difficult to fall asleep, so that when you wake up in the morning, you always feel that you have not slept enough, you do not sleep well, or even feel more tired than before going to bed, such a state is in line with the medical definition of insomnia. Insomnia itself can be a symptom of a variety of sleep disorders, mental disorders and physical disorders, or it can be a separate sleep disorder, or insomnia, which many doctors also call insomnia disorder. One of the most closely linked and complex conditions with insomnia is the two emotional problems of anxiety and depression. It can be said that for every patient who complains of insomnia problems, the first thing to determine is whether the person also has emotional problems and the nature and severity of the emotional problems. Which of the three symptoms, insomnia, anxiety or depression, has a greater impact on a person’s life and work status? A clinical study showed that patients who came to the clinic for insomnia evaluated the subjective perceived sleep quality and used polysomnograms to objectively evaluate their sleep quality, as well as self-rated anxiety and depression scales to evaluate the severity of their anxiety and depression, and finally found that neither subjective perceived sleep status nor objective sleep quality correlated with their quality of life, and only anxiety and depression moods were associated with lower quality of life, with a stronger association for depression. This study suggests that although insomnia patients often emphasize that “not sleeping well” causes many of their problems and mental distress, it is the emotional problems of anxiety and depression that really affect quality of life. Therefore, when discussing the extent to which insomnia affects productivity, it is important not to overlook the possible co-existence of emotional problems. Regarding the impact of sleep deprivation on a person’s work and life status, a common perception angle in society is that insomnia leads to any adverse adverse consequences, and therefore to avoid these consequences, insomnia must be improved first. Unbeknownst to me, there is a peculiar characteristic of sleep after insomnia, often the more you want to fall asleep, the more you want to sleep well and correct insomnia as soon as possible, but the more difficult it is to sleep well. If you insist on the psychological desire of “I must sleep well tonight, I must sleep well”, insomnia is likely to be trapped in a vicious circle of “the more I can’t sleep, the more I want to sleep well, the more I can’t sleep”. Therefore, it is especially important to understand the meaning of sleep more accurately. The significance of sleep to an individual’s life is essentially similar to that of diet. First of all, proper sleep and diet are both essential for an individual to survive, and regular sleep and eating are more important to ensure good health. On the other hand, because the body has a certain ability to self-regulate, in case of special circumstances and have to interrupt eating a meal or a day, of course, there will be hunger and other discomfort, but this meal a day without eating, will not cause serious or long-term damage to a person’s health. The same is true for sleep. If one or two days of sleep are not enough or even missing, of course, there will be sleepiness and fatigue, emotional irritability and other discomforts, but such lack of sleep itself does not cause serious damage to health. For work efficiency, sleep deprivation due to insomnia itself, of course, will have a certain negative impact, work efficiency often slightly reduced, but to complete their usual workload, is generally no problem. When you find yourself in a serious state of decline after insomnia, unable to complete your work as usual, or even difficult to insist on continuing to work, then there must be a problem of anxiety and depression. The specific performance of each person after insomnia, often have their own characteristics, there are many differences between each other, but the common point is that when you find that the efficiency of work after insomnia significantly decreased, but you feel powerless to adjust, you must seek timely medical treatment, the first choice to psychiatric consultation, if the final diagnosis of depressive disorders or anxiety disorders, with the doctor to carry out systematic treatment.
