Sadness is also good for work

According to research by the University of New York, grief helps increase concentration and avoid making mistakes in work.

Sadness and sadness are thought to be able to help people increase their ability to cope with life's challenges, resilience and help people achieve great success.

Sadness helps people have a quiet time to look back at themselves.

Researchers point out that modern society puts personal happiness above all, so people often refuse to be immersed in despair every time they lose their jobs, break relationships or lose loved ones. It is estimated that 1 in 4 people suffers from depression during a certain period of life, and 5% of the world's population is currently suffering from this mental illness.

More and more experts in mental health are concerned that the tendency to take antidepressants may affect human evolution. Because according to them, in the long run, depression can benefit the race.

According to psychologist, Professor Jerome Wakefield of New York University, from a biological point of view, a psychological trait that has been attached to humans for so long is that it benefits in some way. "Otherwise we don't have to carry it with us. We are carrying one of the components that constitutes ourselves, biologically," Professor Wakefield said.

He believes that grief helps people draw lessons from their own mistakes. 'I think one of the functions of negative emotions is to stop us from doing normal activities and focus on something else for a while,' said Professor Wakefield.

A New Scientist article confirms that sadness can also act as a psychological deterrent to prevent us from making mistakes. The risk of falling into suffering may prevent us from being impulsive or unruly, especially in relationships or with other things we value.

Dr. Paul Keedwell, a psychologist at Cardiff University, said that even depression that has been released can help us avoid the risk of long-term psychological stress. He said that if you do not spend time contemplating and sipping sadness, 'one may fall into a state of chronic stress until exhaustion or death'.
