Relaxation techniques are nothing more than a skillful reduction of muscle tension and mental health through relaxation and focusing attention only on what is currently happening. The use of this therapy was started at the turn of the century XIX and XX . With the right tranquility and relaxation, a man gets an injection of energy, can concentrate better, getting rid of fears and all kinds of muscular and skeletal pain caused by stress. There are two relaxation techniques the most widespreaded in the world. The first is a method of Johannes H. Schultz, which bases on so colled autogenic training. For twelve weeks, divided into six stages, there are performed specific exercises in a lying position. These stages correspond to the appropriate areas of the body. The aim of this method is to improve the physical and mental condition of a man, gain self-confidence and calm down. Exercises are performed twice a day for about 20 minutes. At each stage we learn: feeling the weight of the body, feeling the heat, regulating heart rate, breath control, relaxation of the abdominal cavity and internal organs, feeling cold on the head. It bases essentially on the suggestion that, for example, my hand is heavy, I am relaxed and light. A high degree of advancement of this method is a kind of meditation. The second method is a technique of Edward Jacobson, consisting in a nutshell,of the relaxation of individual parts of muscles. It bases on the performance of the appropriate exercises, movements of arms and legs so that the gradual stretching and loosening of muscles leads to their relaxation. There are also exercises with the purpose of learning the proper breathing. Many of the exercises of this method are same as in yoga. On the background of techniques developed by both men, to this day, there are many techniques created. For many, these exercises are just another whim which has no impact on human health. However, all methods of relaxation and concentration done regularly and properly have an impact on quality of life of the person applying them. You only need to look carefully at the various exercises, for example, if you learn to control breathing and pulse, then in stressful situations, you will be able to calm down and concentrate all the energy on what you have to do, rather than trying not to be stressed. These methods allow you to calm down and discharge negative emotions, which makes you calmer, harder to get out of balance, and the “pure” mind works better and more efficiently. The most important is to perform the exercises in silence and without haste. If we plan something very important shortly after the training, it will be difficult in the first weeks to concentrate on them because we will think about it all the time. It is best to begin exercising at bedtime, which also improves the quality of sleep.
