The main category of short-acting sleeping pills is hypnotic drugs, which are more effective for sleeping difficulties, the half-life of this drug is short, the action time is short, the patient can easily wake up if there is external stimulation after falling asleep soon, there is no special discomfort. Long-acting sleeping pills are mainly forced sleep drugs, which prolong the sleep cycle. Under the condition of reasonable medication, patients may not wake up easily after falling asleep, and can wake up gradually under the condition of strong external stimulation, but there may be physical and psychological discomfort, and even dizziness, dizziness and nausea. If the above-mentioned sleeping drugs are consumed in excess and reach a certain toxic dose, it may cause the patient’s central nervous system to be fully suppressed and coma may occur, so it is difficult to wake up quickly.
