     How to build energy into your mornings Here are a few things I've found helpful to become fully

alert (清醒的) from being asleep. Not only does speeding up this wake-up process save time, it makes

waking up less of a struggle.

     Light. Your body's natural clock is tuned to the amount of light. Turn on all the lights in your room

right after waking up. Getting bright lights can help trick your body into thinking it is time to get out of bed.

     Exercise. Put something physical right at the start of your morning. In the summer, I did a quick morning

run and found it helpful in shaking off any sleepiness. Considering the outside temperature hovers (持续)

around--- 20℃, I've stuck to doing a few pushups in my room. The exercise gets your heart pumping and

snaps you out of a groggy (摇摇晃晃的) state.

     The 10-minute rule. If you want to stick with a consistent wake-up time, practice the ten-minute rule.

This means you commit to staying awake for at least the next ten minutes. Once you get over that initial period,

the temptation to go back to bed is usually gone.

     Active work. Start your day with work that actively uses your mind. Creative activities like writing,

drawing, programming or designing work better than passive activities like reading. By focusing your mind

early you can stay focused and brush off any unwanted drowsiness (昏昏欲睡).

     Don't skip breakfast. Wake up early enough to get something to eat. Skipping meals throw your metabolism

out of balance, causing you to gain fat and lose energy. Skipping breakfast also means your blood sugar will

be low in the morning and energy levels down.

    Commit to a sleep schedule. The obvious solution to combat against sleepiness is to get more rest at night.

Carrying a sleep debt throughout the week with the hopes of paying it off on the weekend is a bad strategy.

Instead, compress your work into the morning hours so you can get the 6-8 hours you need each night.

    Turn up the volume. I've found listening to music or audio (音频的) books helpful in keeping myself awake

during the morning. Best of all, if you put on an audio book from your favorite speaker, you can get some

encouragement to start your day.
