Add the smell of citrus - with your body wash, or a couple of slices of lemon to a glass of water. Need a serious boost? Put a couple of drops of citrus, lemon, or bergamot essential oil on a cotton ball and inhale. This is my personal favorite, I love anything citrus.

Take a deep breath - many of the toxins in our body or expelled by breathing, simply close your eyes and take several deep breaths.
Crank up the music - and get up and dance.

Write thank you notes - it's hard to be stressed and feel grateful at the same time. Take a few minutes and write notes to someone who has helped you recently.
Sit up straight - poor posture puts uneven pressure on your spine making your muscles work harder causing them to tighten up. Practice sitting straight when your working, over time it will become a habit.
End your shower with a burst of cold water - a quick short blast will perk you up.
