4、 time? A growing body of research suggests that paying attention to the body clock, and its effects on energy and alertness, can help pinpoint the different times of day when most of us perform our best at specific tasks, from resolving conflicts to thinking creatively. 1. Keep pace with natural rhy

5、thms. Most people organize their time around everything but the bodys natural rhythms. Workday demands, commuting, social events and kids schedules frequently dominateinevitably clashing with the bodys circadian(生理节奏的 )rhythms of waking and sleeping. Disruption of circadian rhythms has been linked t

6、o such problems as diabetes, depression, dementia(痴呆 )and obesity, says Steve Kay, a professor of molecular and computational biology at the University of Southern California.

7、thms in response to light and other natural stimuli, it “gives us an edge in daily life,“ Dr. Kay says. When it comes to doing cognitive work, for example, most adults perform best in the late morning, says Dr. Kay. As body temperature starts to rise just before awakening in the morning and continue

8、s to increase through midday, working memory, alertness and concentration gradually improve. Taking a warm morning shower can jump-start the process. The ability to focus and concentrate typically starts to slide soon thereafter. Most people are more easily distracted from noon to 4 p. m. , accordin

9、g to recent research led by Robert Matchock, an associate professor of psychology at Pennsylvania State University. Alertness tends to slump after eating a meal, Dr. Matchock found. Sleepiness also tends to peak around 2 p.m., making that a good time for a nap, says Martin Moore-Ede, chairman and ch

10、ief executive of Circadian, a Stoneham, Mass. , training and consulting firm. 2. Make good use of fatigue. Surprisingly, fatigue may boost creative powers. For most adults, problems that require open-ended thinking are often best tackled in the evening when they are tired, according to a 2011 study

11、in the journal Thinking 6 a. m. messages are most likely to be read, says Dan Zarrella, social-media scientist for HubSpot, a Cambridge, Mass. Reading Twitter at 8 a. m. or 9 a. m. can start your day on a cheery note. Thats when users are most likely to tweet upbeat, enthusiastic messages, and least

12、 likely to send downbeat tweets steeped in fear, distress, anger or guilt, according to a study of 509 million tweets sent over two years by 2.4 million Twitter users, published last year in Science. One likely factor? “Sleep is refreshing“ and leaves people alert and enthusiastic, says Michael Walt

13、on Macy, a sociology professor at Cornell University and co-author of the study. The cheeriness peaks about 1-1/2 hours later on weekends perhaps because people are sleeping in, Dr. Macy says.

14、m between 3 p. m. and 6 p. m. , when many people lack energy to share their own tweets and turn to relaying others instead, Mr. Zarrella says. And posts to Facebook at about 8 p. m. tend to get the most “likes,“ after people get home from work or finish dinner. At that time of day, theyre likely to

15、turn to Facebook feeling less stressed. “You have less stuff to do and more time to give,“ says Mr. Zarrella. Late-night drama can be found on Twitter, where emotions heat up just before bedtime, between 10 p. m. and 11 p. m. , says Scott Andrew Golder, a Ph. D. candidate at Cornell University and c

16、o-author of the Twitter study. At that time, people tended to send more emotion-laden tweets, both positive and negative. Tired out by the workday, but also freed from its stresses and demands, people become “more alert and engaged, but also more agitated,“ Dr. Macy says. 4. Choose the right exercis

17、e time. When choosing a time of day to exercise, paying attention to your body clock can also improve results. Physical performance is usually best, and the risk of injury least, from about 3 p. m. to 6 p.m., says Michael Smolensky, an adjunct professor of biomedical engineering at the University of

18、 Texas, Austin, and lead author with Lynne Lamberg of “The Body Clock Guide to Better Health.“ Muscle strength tends to peak between 2 p. m. and 6 p. m. at levels as much as 6% above the days lows, improving your ability to grip a club(高尔夫球杆 )or racquet.

19、m the lungs, which function 17.6% more efficiently at 5 p. m. than at midday, according to a study of 4 756 patients led by Boris Medarov, an assistant professor of medicine at Albany Medical College in New York.
