3. Breathe
If you do not have the space to perform stretching exercises, you can also take advantage of the revitalizing breathing techniques of yoga: While sitting, fully straighten your spine, put one hand on your chest, another on your abdomen and breathe in such a way that it moves plus the hand you have on your abdomen. Spend a full minute taking a series of abdominal breaths for the count of two, inhaling and exhaling firmly. This type of breathing not only promotes blood circulation, but also helps you with concentration and with conditions such as headaches and back pain that can take away your vitality.
