Throughout the year, the Millennium is the solar term with the largest temperature difference between day and night. Although there is still a trace of hot air during the day, we can feel the coolness at night. At this time, the yang of nature will gradually converge, and the yin will become more and more prosperous.
From the point of view of TCM health preservation, people's daily life should also conform to this change of yin and yang in nature, go to bed early and get up early as possible, and exercise properly after getting up at dawn, which is conducive to the spread of lung qi and the rise of yang in the body.
在一年四季中，白露是昼夜温差最大的节气，虽然白日间仍有一丝热气，但一入夜，我们就能感受到丝丝凉意。此时，大自然的阳气逐渐收敛，阴气将越来越盛。
从中医养生的角度来看，人的起居也应顺应自然界的这种阴阳变化，尽量早睡早起，天亮起床后适当活动，有利于肺气的宣发和体内阳气的升发。
