The seven emotions are as follows:
Rage: racing heart, flushed face, high-pitched voice, dilated veins in the skull, bulging eyes, sweating, tensed voluntary muscles, distorted mimicry muscles (raised eyebrows, flashing teeth, tightened jaw), etc. All this is due to raised cortisol or adrenaline-like (main fight/flight hormone in the body) levels in blood, working on the "rage centre" in the Limbic System (subconscious) of the brain. If more are not secreted, the body calms down quickly. If irritation prevails, the rage is prolonged.
Fear: spasm of blood vessels, pale face, cold hands and feet, constricted eyelids, shallow breathing, cold sweat, erratic heartbeat, tendency to shun light. No one knows what hormone triggers the "fear centre." It's longer lasting.
Grief: slow heart rate, atonic mimicry muscles, tears, loss of appetite, frequent sighing, feeble voice, insomnia, poor motivation, sluggishness and other symptoms of depression. I suppose it's serotonin or its derivatives that causes this.
Passion/Lust: racing heart, extreme pleasure, unstoppable desire, hypersensitivity of the sensory organs (touch, smell, heat, vision, pressure, hearing, taste), easy sexual arousal, enhanced creativity (with words, songs, art, etc.). The corresponding hormone probably originates in the pituitary. The sexual drive centre has been mapped and is located above the pituitary gland.
Happiness/Pleasure: great sense of well-being, "happy face," increased energy, relaxed muscles, normal heartbeat, increased tolerance, good sleep, pleasant temperament, etc. These hormones must be sympathetic in nature, but are slower/less aggressive than adrenaline.
Jealousy/Vendetta: a nerve-wrecking chronic emotion with insomnia, persistent thoughts, desire to harm, constant conflict in the mind, tensed muscles, very tight jaw and temple muscles as if "wanting to bite," irrational behaviour. The hormone, once secreted, takes a long time to disseminate. It probably originates adrenal glands because of its aggressive nature.
Anxiety/Stress: heightened state of alertness, tensed muscles, insomnia, increased pulse rate, lack of concentration, extreme mood swings, irritable, short term memory loss, high pitched voice, change of appetite, etc. This is a chronic condition which frequently leads to exhaustion, weak immune system and can cause diseases like blood pressure, period disturbances, auto-immune disease, loss of libido, and cancer. Here it is obvious that cortisol or adrenaline is the hormone that causes all this. Anxiety has long and short-term negative effects on the body and so scientists have done a lot of work to study it. It seems the body gets conditioned to the stress and the hormones may not be stimulated in large amounts. If that were so, the adrenal glands would be exhausted and fail permanently.
Stress management is very important to maintain a balanced life and to prevent most common ailments. Stress basically uses up the body's reserve energy and so the various organs fail to function normally.
Some organs like the heart and brain suffer due to overuse and malfunction. Emotional centres are mapped by scientists and the are located in the subconscious brain but analyzed and "felt" in the frontal lobe of the brain. Some 60 years ago lobotomy (surgical removal of the front part of the brain) was used to treat patients with severe mental illnesses. They simply stopped "thinking" and "feeling emotions." It was an inhuman treatment as such patients became like animals.
Meditation, prayers, music, biofeedback, chanting, and relaxation raise your threshold for response to stress. They also directly effect the emotional centres and control their sensitivity.
