1. Drink lots of water
Keep a bottle of water with you and sip it throughout the day. Dehydration can leave you feeling sluggish and sleepy.

2. Have a good breakfast
Breakfast is the most important meal of the day! Avoid greasy, sugary and carb-filled food. Opt for fruits, wholegrain bread and yogurt.

3. Take a walk 
This can boost energy levels and decrease fatigue. Making this a daily habit can also add seven years to your life. To stay well, walk for 30 to 45 minutes nearly every day. Do it all at once or in chunks as short as five to 10 minutes. Aim for a brisk pace of three to four miles an hour, but remember that you’ll get plenty of benefit from strolling at a slower pace as long as you stick with it.

4. Listen to music 
This can increase your concentration levels, keep you awake or even give your mood a boost. Studies  have shown that 9 out 10 people worked better when they were listening to music!

 5. Power nap

Search for a quiet place at work to lay down. Consider stashing a pillow and blanket in your drawer if you plan to nap in your office to help relax you. Keep naps short. Aim to nap for only 10 to 20 minutes. The longer you nap, the more likely you are to feel groggy afterward.
