OUR DAILY PULSE 每天的节奏

The shifts of energy that we experience are tied to the ultradian rhythms that regulate physiological markers of alertness at 90-to 120-minute intervals.

我们的精力变化与次昼夜节律有关。次昼夜节律会每90-120分钟调节生理表征。

In the absence of any artificial interventions, our energy stores naturally ebb and flow at different times of the day. Somewhere around 3:00 or 4:00 P.M. we reach the lowest phase of both our ultradian and our circadian rhythms.

若是没有人为的干预，我们的精力的存储在一天中会自然低波动，大概在下午3或4点，会达到昼夜节律和次昼夜节律的最低点。

Brief catnaps sometime in the afternoon—consistently report that they sustain high energy well into the evenings.

下午短暂小睡的人一般晚上也会精力充沛。

我的思考My Thinking

我中午一般是午休或者打乒乓球，两者都可以让我感到不困，不过我发现午休比运动的效果更好，运动后下午三四点还是发困。鉴于中午休息比运动更能恢复精力，以后中午一定要午休一下，毕竟40分钟的休息可以提高34%的效能。

I usually nap or play pingpang, which energize, but I feel tired between 3-4 pm when playing pingpang, so I concluded that napping is better than exercise. I will try to nap at noon as 40 min nap will improve 34% of performance.
