生命在于运动。流水不腐,户枢不蠹。有道是一日之计在于晨,有些老年人东方一放鱼肚白,就起床出门晨练,日复一日,形成了“闻鸡起舞”的习惯。对此,有越来越多的养生学者提出质疑,认为:晨练必须肯定,但时间上还须随季节而调整,冬季晨练以“必待日光”为准。 Life is movement. Water is not rotten, households are not beetles. The only way to do this is to look forward to the morning. Some elderly people take the morning exercise after getting out of the east. From day after day, they form a habit of “dancing with chicken”. In this regard, more and more health scholars questioned that: morning exercise must be affirmed, but time must be adjusted with the seasons, winter morning exercise to “must be daylight ” shall prevail.
