STEP 1 Eat right 正确饮食

Eat plenty of protein, fruits, and vegetables. Avoid overeating starchy foods like pastas, breads, and rice. They can make you drowsy.

Snack on almonds and cashews, which contain magnesium, a mineral that converts sugar into energy.

STEP 2 Stay moving 动起来

Stay moving. Go for a brisk 10-minute walk to give you a boost that could last up to two hours.

STEP 3 Get a quick jolt 快速“动”一下

Splash cold water on your face and pulse points and expose yourself to bright light for a temporary jolt of energy.

STEP 4 Have some decaf 喝点“低咖啡因”饮品

Try the placebo effect. One study found that drinking a cup of decaf coffee left most people feeling just as awake as drinking the real thing.

If you need to be up late, take a preemptive nap to keep from nodding off; it's more effective than caffeine at keeping people up and alert.

STEP 5 Use aromatherapy 做香薰按摩

Use stimulating smells. The scent of peppermint and rosemary essential oils has been shown to increase alertness. So breathe deep and enjoy a natural, caffeine-free boost of energy.
