To go out of your comfort zone and experience positive stress is a good thing, but only for a short duration. When the ‘positive’ stress lasts too long, the body gets overwhelmed, and the stress becomes negative. That is why you have to be careful with too much stress. If you experience too much stress for a prolonged period of time, you have to get some rest and take a step back.
A healthy level of positive stress empowers you in three ways. First of all, eustress helps you emotionally: positive feelings of motivation, inspiration, and confidence increase. Secondly, it helps you psychologically, namely the eustress helps you build independence and optimism. Last but not least, positive stress brings you benefits on a physical level: it helps you build up and strengthen your body.
Usually, you already experience the effects of eustress in your life. Nonetheless, it is good for your mental health and body to find ways to make eustress a common part of your everyday life. For example, you can challenge yourself by learning something new every day. This does not always have to be a big thing. Also, smaller things enable the desired effect. Put yourself outside of your comfort zone, and keep practicing. In addition, it helps to set some personal and professional goals to challenge yourself!
