The expression on your face can usually dramatically alter your feelings and perceptions, and it has been proved that deliberately smiling or frowning can create corresponding emotional responses. The idea was first put forward by a French physiologist, Israel Waynbaum, in 1906. He believed that different facial expressions affected the flow of blood to the brain, and that this could create positive or negative feelings. A happy smile or irrepressible laughter increased the blood flow and contributed to joyful feelings. But sad, angry expressions decreased the flow of oxygen-carrying blood, and created a vicious circle of gloom and depression by effectively starving the brain of essential fuel. Psychologist Robert Zajonc rediscovered this early subject, and suggests that the temperature of the brain could affect the production and synthesis of neurotransmitters-which definitely influence our moods and energy levels. He argues that an impaired blood could not only deprive the brain of oxygen, but create further chemical imbalance without inhibiting these vital hormonal messages. Zajonc goes on to propose our brains remember smiling associated with being happy, and that by deliberately smiling through your tears you can allow your brain to release neurotransmitters uplifting-replacing a depression condition with a happier one. People suffering from: psychosomatic, depression and anxiety states could benefit from simply exercising their zygomatic muscles--which pull the corners of the mouth up and back to form a smile-several times an hour.
