Self-massage: It is necessary to massage your shoulders, neck, head, lower back. It helps a lot. Another great relaxation technique is to tense up and then relax each muscle in your body, one at a time, starting from your toes up to your head.
Exercise: You may ride a bicycle or go for walk instead of taking buses. It really gets the stress out of your system and gives you some quiet time to think when you exercise, such as jogging.
Meditate: You don’t need to be trained to have a short, relaxing meditation session.
Deep breathing: Take a deep breath. Hold it, then let it out slowly. When other things pop into your head (they will, inevitably), acknowledge them (don’t try to force them out) and allow them to leave. Just sit somewhere quiet, close your eyes, relax, and focus on your breathing. Try to concentrate on it coming into your body, and then going out.
Take a nap: Just take a 30-minute nap, and you will return to the job with renewed vigour. A nap is like a restart button for life.
Have a breakfast: One can not keep full of energy in the whole day without breakfast. It makes sense to include low-fat and high protein dairy in your diet according to the docter, as protein can increase the secretion of adrenalin which helps to concentrate.
