Usually we are more familiar with the three “one minute”, that is, people wake up in bed for a minute; after getting up in bed for a minute; after getting up legs down and so on for a minute, this is a better practice to get up. Wait a minute after waking up, this time can make the human body and the cerebral cortex gradually awake, so that the human body is in an awake state after waking up. If the cerebral cortex is awake, but the human body is not yet awake, the body may be weak. In addition, after waking up, because the body’s blood pressure is not yet regulated, it may faint due to insufficient blood supply, especially for some elderly people or those who are weak. It takes some time for the human body to respond. When the body is not fully awake, the body’s protective response is poorer, the blood supply is insufficient, and the brain may be in a transient ischemic state. This is why many people have the possibility of fainting when they are not fully awake in size. When people sleep, breathing, blood pressure, pulse, etc. are in a relatively low state, body temperature will also be 1-2 degrees Celsius lower than normal, human metabolism is also low, this minute can provide time for the body to gradually return to a normal state. The human body from sleep lying to sitting, and then to stand after getting up, from a variety of human body mechanisms, the human body has not been completely converted from sleep state, legs down for a while, or hands and feet activities, etc., is conducive to the body’s full awake, to avoid some unexpected events.
