Test "The state of your nervous system" (According to K. Liebelt)

Instruction. Circle one of the four numbers in the boxes to the right next to the description of each symptom, depending on how often you find this symptom in yourself.

Results processing: Add up the circled numbers.

0–25: this amount may not bother you. However, still pay attention to the signals of your body, try to eliminate weaknesses.

26–45: There is no cause for concern in this situation. However, don't ignore the warning signs. Think about what you can do for your body

46–60: your nervous system is weakened. Health requires a lifestyle change. Analyze questions and answers. This way you will find the direction of the necessary changes.

Over 60 points : your nerves are severely exhausted. Required Urgent measures. Be sure to see a doctor.

The human nervous system is a rather complex structure that permeates the body and allows for its normal functioning, since with its help we react to any external and internal influences. On the this moment there is already evidence that nerve endings present in various organs immune system, and the main function of this system is to receive, as well as store and process any information received.

It is likely that you yourself paid attention to the fact that occasionally you become too irritable, quick-tempered, and also quickly get tired. All this ultimately has an extremely negative effect on the functioning of your nervous system, and also affects your health. Everyone knows the expression "all diseases are due to nerves." That is why it is important to understand the current state of the nerves, the degree of one's balance and be able not to worry in vain, since often this feeling is simply greatly exaggerated. If you want to waste yourself on your nerves as little as possible, just try to do more of what brings you positive emotions. Take the test and find out how in order your nervous system is.

• You are dominated by the imbalance of the nervous system. It sounds like you need to get serious about treating your nerves and also reducing as much as possible the presence of factors that piss you off, whether it's your job or a failed relationship. Do not put off solving your problem, because nerves are very important.

  The test showed that you have a nervous imbalance. You should devote more time to rest and relaxation, as well as reduce the number of irritants in your life. Remember that the most important thing in life is you. Don't let people negative factors ruin your precious nerves.

  Unfortunately, the state of your nervous system is uncertain. We recommend you retake the test. You have too many conflicting and mutually exclusive answers. Perhaps you should take a closer look at some of them.

  There is a balance. Despite minor troubles and unrest, your nerves are in order. You know how to relax and take control of yourself. Your nerves are strong enough to keep you in a good mood and productive.

  Blimey! You have what is called - " nerves of steel". Problems and troubles are very difficult to piss you off. People around you can feel calmer and more confident with you. Good mood and deep sleep, for sure, are your life companions. You are very lucky!
