Anger is an emotion just like sadness, happiness or fear, but it can be unhealthy if in excess. It can have long term side effects on both physical and psychological health which in turn can adversely affect one's family and profession.
Anger is closely associated with hypertension, headache, kidney disorders on one side and may lead to depression, insomnia, anxiety on the other. Frequent outbursts of anger can push your loved ones away from you and you may even face lower concentration in work.
The cause of this needs to be evaluated as it may be due to underlying depression or stress or even due to some medical causes. You can practice some simple anger management tips like a healthy lifestyle with time for good sleep, morning walk, some pranayam, healthy and timely eating along with some recreational activities like playing games, spending time with friends besides others. Kindly consult a psychiatrist for thorough evaluation if this doesn't provide relief.
