First, calm yourself down. Especially when you are in a mood, closing your eyes or walking to a quiet place with no one can make you feel much better.
Second, take a deep breath. When you are in a bad mood, closing your eyes and taking a deep breath is very effective. Especially when you are in the wild, the fresh air can make people forget all the unpleasantness.
Third, drink a sip of water. Drinking a sip of water is also very helpful for calming the mood. Cold water is best, boiled water is enough. The effect of milk and orange juice is not necessarily better than that of boiled water and mineral water. Even better, you can also listen to a piece of music. A quiet piece of music can also calm you down, but don't listen to too passionate rock. You can also move your arms.
If possible, you can move and turn your arms. Doing gymnastics can relieve the body's stress and make you feel better. If there are green plants indoors, you might as well look at the green ones. Plants can calm your irritable mood, and the plants have fragrance that can calm you down.
Exercise can distract you from your irritability. You can go for a run or swim, which is very helpful to divert your attention.
