Therefore, when taking a nap, we should avoid strong external stimuli, and it is more appropriate to control the sleep time at 1 hour. If the time is too long, we will feel sleepy and feel better than not sleeping. Speaking of taste, many people will naturally associate it with eating, and many people will feel more sleepy after eating food. Vinegar can be used to wake us up, because vinegar can not only promote digestion, but also stimulate people's bodies with a strong smell. However, vinegar is too irritating to drink directly, which will harm the gastric mucosa. It's best to dilute it before drinking. On the one hand, sleepiness is related to the acidity of body fluids. Eating more alkaline foods can neutralize the acidic substances produced during muscle fatigue and make people eliminate fatigue. Although vinegar is sour, it is an out-and-out alkaline food after human metabolism. At the same time, the use of taste stimulation to refresh the mind can stimulate human nerves in lazy spring days, increase appetite, meet the increased energy demand brought by vigorous metabolism, quickly enhance immunity, easily recover physical strength, and drive away the fatigue of spring sleep in a full state.
