一、别坐着午睡:医学家们曾做过观察,当人们熟睡后,心率就变慢,血管扩张,流经各种脏器的血液速度相对减慢。若坐着睡觉,流入大脑的血液就更加少,特别是午饭后,较多的血液要进入胃肠系统,加之坐睡时,弯着腰,两腿蜷缩着,呼吸沉闷,加重了脑组织供血不足。 First, do not sit and nap: Medical scientists have done observations, when people sleep, the heart rate becomes slow, blood vessels expand, the blood flow through various organs relatively slow. If you sit and sleep, the blood flow into the brain is even less, especially after lunch, more blood to enter the gastrointestinal system, combined with sit and sleep, bending over, curled up his legs, breathing dull, aggravating the brain tissue for blood insufficient.
