First, gastric ulcer
Anger can lead to sympathetic nerve excitement, which directly affects the heart and blood vessels, resulting in relatively reduced blood supply to the gastrointestinal tract, slow peristalsis, loss of appetite, and even severe gastric ulcer.
Second, long spots.
When people are angry, a lot of blood rushes to their heads, and the oxygen carried in the blood will decrease and the toxins will increase. Toxins can adversely stimulate hair follicles, cause inflammation around hair follicles, and lead to pigmentation problems.
Third, liver injury.
When angry, the human body will secrete a substance called catecholamine, which can act on the central nervous system, increase the blood sugar content and strengthen the decomposition of fatty acids, resulting in more and more toxins in blood and liver cells.
Fourth, it causes hyperthyroidism.
Anger can lead to dysfunction of endocrine system, and promote thyroid gland to secrete hormones, which can easily lead to hyperthyroidism after a long time.
