Here are some quick energy boosts to get you through the day:
 
Stand up, stretch and take a couple of deep breaths. Stretch your arms, back, legs, and neck. Take a deep breath through your nose, hold it, and let it out slowly and forcefully. Do this a few times and you should feel a bit more alive. Other actions you can try are:

• briskly rub the palms of your hands together
• massage your shoulders and neck
• pat gently under your navel
• stand up and brush your hands down your arms and legs
• Clap the inside of your wrist like you were clapping your hands, but instead of clapping the palm, you clap the inside of one wrist with the other hand. Clap 5-7 times, and then switch sides and clap the other wrist. 
  

Use Aromatherapy. For a quick energy boost, keep a bottle of peppermint, cypress, eucalyptus, spearmint, or geranium essential oil handy. Place a few drops on a tissue and inhale deeply.  


Jumping Jacks: You might look like a bit of a dork, so find an empty place in the office and do a few jumping jacks - they're great for building an energy buzz without a massive amount of effort.

Hydrate Yourself: Before you head to the coffee machine in search of a pick-me-up, drink a big glass of water. 

Get Moving: No wonder you feel flat - you've been sitting in the same chair hour after hour, without moving much more than your fingers! Instead of sending an email, go to your colleague's office. Schedule a walking meeting. Take the stairs to the restroom a few floors away. Just find a reason to move around and be more active.

Alternate nostril breathing: Spend a couple of minutes breathing through alternate nostrils, it helps to give you an oxygen boost.

Eat lots of berries: Especially berries that are blue, red, or purple. The color comes from anthocyanins, a powerful antioxidant, that boosts energy.

Use caffeine wisely: Coffee and caffeinated drinks can boost your alertness, but be careful about letting it be a habitual crutch. The temptation to drink more caffeine to get even more energy will be strong. Eventually you’ll be downing 5 double-shot espressos a day just to function. Drink coffee earlier in the day to avoid insomnia, which will make the next day worse.

Herbal tea: Instead of reaching for caffeine to give you a fix, opt for a cup of herbal tea instead - peppermint, lemon or ginger are all good choices to perk you up.
