Fitness is not only helpful to physical health, but also can adjust people's mentality and make mental health develop. 1, a good way to cultivate self-confidence. Nowadays, the social competition is becoming more and more fierce, and everyone is facing pressure from all sides. Although these pressures are the driving force for people to move on, they are also the source of people's pessimism. In the face of pressure, many people will gradually stop believing in themselves because of a strong sense of frustration, and begin to feel pessimistic and disappointed in themselves, which is why they are devastated. In fact, fitness is the same. It is impossible to achieve good results and functions at the beginning. We all started from the basic goal. Every progress will make us feel very excited and happy. In the process of accumulation, there will also be bottlenecks that cannot be overcome for the time being. If you choose to give up at this time, you will definitely let the previous efforts go to waste. If we don't want to, we can only tell ourselves that we can do it and cheer for ourselves. Stick to this belief. When one day you really break through the bottleneck through hard work and make a qualitative leap, the joy of success and the pride of conquest will make you truly realize the magical power brought by self-confidence, and then bring this belief into your daily life to deal with various pressures. Who will give up easily? 2, self-regulating regulator People are doing many of the same things every day-work, study, life, bland, nothing new, and after a long time will inevitably produce fatigue and even disgust. At this time, it is necessary to change the environment to adjust the tired body and mind and relieve the nervous nerves. Appropriate fitness activities can not only divert attention and give the brain new stimulation points, but also release an emotion at the new stimulation points, so that the tired mentality can be relaxed and rested. An adjusted state of mind, like a car full of oil, will come back to life with full throttle. Many people have this experience. When they are in a bad mood and sweat profusely in the gym, their mood will change. Why? Relevant researchers have found that the human body will produce a substance called "endorphin" in the process of fitness, which can make people's body and mind in a relaxed and happy state. Endorphins, also known as "happy hormones" or "young hormones", can make people feel happy and satisfied and help people relieve stress and unhappiness. 3. Effectively prevent the occurrence of depression. Now with the increase of social pressure, more and more people do not adapt to the pressure, and there are different degrees of depression. People who are prone to depression often have negative emotions because they can't face the pressure, and they begin to escape from society and are no longer willing to face all objective facts. Taking part in fitness activities is a positive attitude to meet challenges, which not only exercises the body, but also gives a hint to the psychology, that is, face life positively, stop being afraid of pressure and become more confident. According to some data, the probability of people who often participate in fitness activities suffering from depression is only 0.0 1%. Today, with more and more emphasis on the quality of life, everyone is eager to have a healthy body and a positive attitude, so don't waste a good time, go to the gym more often when you have time, and enjoy the vitality brought by fitness in sweat!
