Experiencing an overwhelming anger could damage your physical and mental health not to mention your relationship with others, so it is important to calm yourself down for your own good and for the sake of people around you.
One of the techniques to control anger in the moment is to take a break; stop what you are doing and get away from whatever upsetting you to make it easier for yourself to cool down. You do not have to respond to the situation promptly; when you get angry remember to step outside and go to another room to give yourself a chance to calm down.
Try positive self- talk to change the way you think from negative to positive, for example if you are subjected to road rage, try telling yourself “this person might be having an emergency and very likely I will never have to see him again.”
Try sharing your concerns with someone close to vent your anger, and clearly express to this person from the beginning if you want sympathy or advice or a solution to a problem. Set a time limit to vent your anger, as this helps you move on rather than living the situation endlessly.
After you calm down, try to find the light side of the situation because casting humorous light can change your emotions from anger to humor. Exercise can help in calming down due to the endorphins resulting from the physical activity.
There are different forms of exercise that can help manage anger such as running, weight training, yoga, swimming and boxing. Getting enough sleep is essential to manage your emotions properly; it can lessen your anger and improve your mood. If your anger reached a point that you cannot maintain positive relationships, then you need to see a therapist, who can assess you with some medication.
