  Experts said that if the alarm is louder, it is easy to frighten people, cause vasoconstriction, speed up the heartbeat, and induce or aggravate heart disease, cerebral arteriosclerosis, and myocardial infarction. Irritating ringtones can also make a person’s nervous system highly stressed, which may cause indigestion, poor appetite, constipation or diarrhea.
