Office workers who have been woken up by a harsh alarm clock for a long time are prone to high blood pressure. Because people are suddenly awakened by the alarm clock in deep sleep, it will cause the body's protective conditioned reflex, the adrenaline level in the body will rise rapidly, the heartbeat will accelerate, and the systolic blood pressure will rise. Long-term exposure to this stimulus is likely to lead to a series of sleep problems and even high blood pressure.
Often being woken up by an alarm clock will bring more diseases.
Ringtones will also increase your overall stress level.
Going to bed after the alarm clock rings will make you more tired, but you don't have a good rest and keep your spirits up.
