PHYSICAL HEALTH ISSUES
In many ways, mental health is just like physical health: everybody has it and we need to take care of it.
Good mental health means being generally able to think, feel and react in the ways that you need and want to live your life. But if you go through a period of poor mental health you might find the ways you’re frequently thinking, feeling or reacting become difficult, or even impossible, to cope with. This can feel just as bad as a physical illness, or even worse.
Mental health problems affect around one in four people in any given year. They range from common problems, such as depression and anxiety, to rarer problems such as schizophrenia and bipolar disorder.

DEPRESSION
Depression (major depressive disorder) is a common and serious medical illness that negatively affects how you feel, the way you think and how you act. Fortunately, it is also treatable. Depression causes feelings of sadness and/or a loss of interest in activities once enjoyed.

AFFECT THE RISPERATORY SYSTEM
Diseases of the respiratory system. Diseases and conditions of the respiratory system fall into two categories: viruses, such as influenza, bacterial pneumonia, enterovirus respiratory virus; and chronic diseases, such as asthma and chronic obstructive pulmonary disease (COPD)
