I think the relationship between personality and health is mainly achieved through the secretion of some hormones in the body. For example, when we are happy, we secrete dopamine, which is beneficial to heart health, so when we are angry, sad and depressed again, the proportion of different hormones in the body will change, which will affect our health in the long run.
In addition, psychological suggestion is also a factor affecting physical health. For example, excessive denial of oneself can lead to depression. In addition, we often see that doctors will ask patients to have a better attitude and psychologically suggest that they will be fine, which is conducive to the improvement of their condition.
The cultivation of positive personality is a long process. You can use some tips to ask yourself in the early stage, and you can write down some requirements for yourself tomorrow on the wallpaper of the mobile phone lock screen. Then when you turn on your mobile phone the next day, you will think of these things, so that you can have a positive attitude.
In addition, I think if you want to have a good personality, you must be open-minded, optimistic, generous and informal, and you should not think too carefully because of some small things, so that you will not be affected by some small things.
Secondly, there is a saying that people who live near Zhu Zhechi are black. If you are with those optimistic people, you will be infected.
In a word, personality and health are closely related. If you want to live a long and healthy life, you must have a positive and optimistic personality.
