A new study that was conducted on the effects of anger and hostility on general health and especially lungs shows that these moods change the neurological and hormonal processes in the body leading to malfunctioning of the immune system and chronic inflammations.
It was found that constant or prolonged anger impairs lung function and speeds up their aging.

Six hundred and seventy men had been monitored for eight years. At the beginning of the study, their levels of hostility were measured as well as the lung functions. Even then it was noticed that men with higher levels of hostility and anger had impaired lung functions. The average hostility score was 18.5, but it actually ranged from 7 to 37.

Their anger levels and lung functions have been measured again on three separate occasions. The lung function of those men who were angry at the beginning of the study appeared to get worse at each examination throughout the study. Also, each increase in anger caused faster natural decline in lung function and less air volume that can be forced out of the lungs in one second.

Besides the lung damage, anger as well as stress have been also linked to cardiovascular disease and asthma.
