The right amounts are essential for normal functioning. Certain foods provide more energy than others, some provide it quickly and others are released slowly into the system. Energy is used to perform muscular work and to maintain body temperature. Water comprises two-thirds of our body weight and the human cannot survive for more than a few days without water.
Many foods contain high levels, but it is also important to drink sufficient water on a daily basis.
The pressures of modern life restrict our breathing and for the most part we are unaware of how much. Restricting the breathing is restricting our energy. For best results practice deep breathing outside, walking or sitting in the garden, or on the beach, and make the most of fresh air. We breathe more deeply and spontaneously once we move out of doors. You will find that your mind clears and your body has fresh energy and has better metabolism due to the increase in oxygen and the reduced level of carbon dioxide in the bloodstream.
