Why do I often feel chest tightness and sometimes have difficulty breathing? Is it serious when the mood is bad and the weather is hot?

Generally, there are two main factors: physiological and psychological. Psychological factors are mainly caused by unpleasant emotions such as depression and unhappiness. Physiological factors may be neurological disorders, airway obstruction, etc. You can't rule out heart problems. I suggest you go to the hospital for a check-up to avoid delaying your illness. If no organic lesions are found after hospital examination, no treatment is needed. Pay attention to keep a good mood, be cheerful and optimistic, strengthen physical exercise and be calm, so as to be healthy naturally. I hope my answer is helpful to you, and I wish you health and happiness!
