By taking a rest every hour, (or less if your body says so!) you will actually
accomplish more in a day. Do the exercises below, and you will feel more
energetic.
Press your forehead into your palms, resisting forward motion with
your hands. Hold for 15 to 30 seconds. Clasp your hands behind your
head and press your head back. Resist any motion with your hands,
holding for 20 seconds. Turn your head to one side, resisting any motion
with your hand. Switch sides and hold for the same amount of time on
each side. Then, tilt your head to one side, resisting any movement with
your hand, again, holding the position for 20 seconds on each side. Step
away from your computer for awhile. Shrug your shoulders up to your ears,
hold 10 seconds, then release. Repeat 3 times. Rotate each shoulder
separately forward and backward for 20-30 seconds each. Shake your
hands out. Shake your whole body. This will boost sluggish circulation
and help avoid stiff muscles.
To avoid a stiff neck, slowly drop your head fully forward, then backward
(only to point of discomfort, each for 10 secs.) Then tilt forward and rotate
4 times to each side. "Palm your eyes" by vigorously rubbing your hands
together and placing them over your eyes. Cup your hands so that they
cover, not press the eyes. RELAX! This works best while reclining or lying
down.
