In another tip, they suggest drinking water first thing in the morning and throughout the day to stay hydrated.
在另外一个方法提示中，他们建议，早上第一件要做的事就是喝水，且一整天都要喝水以保持充足水分。
While sleeping, you will sweat, breathe, and get up to use the bathroom, and these things all work to dehydrate the body.

据报告，早晨按时吃早点的人感觉更清醒。
For foods high in simple sugars, like donuts, the alertness will wear off quickly, and those high in fat will cause you to eat more throughout the day.
像甜甜圈等单糖含量多的食物，会迅速消耗掉警觉性，那些脂肪含量高的食物会导致接下来的一天吃得更多。
But meals high in fiber and carbohydrates like oats are linked to lasting alertness throughout the morning, the video explains.
但是视频里解释说，像燕麦等富含纤维和碳水化合物的食物能使人一上午都保持清醒。

Drinking orange juice will also give you a boost in the morning, they say, as citrus fruits are rich in flavonoids.

Finally, the team suggests listening to music when you first get up.
最后，研究团队建议早晨起床后可以听点音乐。
Music can cause the pupils to dilate and increase blood pressure, inducing a "state of arousal".

Listening to music also increases activity in the areas of the brain linked to movement and emotion, and can help to release dopamine throughout the body to activate positive feelings.
