Mental health and anxiety disorder

While both fear and anxiety can provoke an arousal response, their other effects diverge. Very intense fear sometimes serves to "freeze" the body to protect it from harm, causing little or no change in heart rate and blocking the impulse to move. In anxiety, the physical changes caused by arousal lead to a second stage marked by thought patterns such as worry, dread, and mental replays of anxiety-arousing events.

Experts have yet to agree on the root cause of anxiety disorders. In fact, most concede that several factors may be at work in each case.

Biochemical theory suggests that biologic imbalances, perhaps among the neurotransmitters in the brain, may be the primary cause of anxiety disorders. Indeed, in one study researchers were able to trigger a panic attack in some people simply by infusing certain chemicals. Many scientists involved in anxiety research now argue that correcting biochemical imbalances with medication should be the first goal of treatment. Other studies suggest that biochemical changes can also be achieved through the psychological and behavioral changes produced by psychotherapy.

Stress, trauma, uncertainty. Most theorists agree that, other factors aside, stress, trauma, and uncertainties can play a role in the development of anxiety disorders. Studies show a relationship between anxiety and stress, which can be defined as a consequence of adapting to a change. Challenges such as the death of a loved one require a major adaptation that can contribute to the development of an anxiety disorder. Uncertainty during transitions, or about the future, can also produce anxiety. Some studies have found that a stressful event precedes the appearance of many anxiety disorders, though this result is not yet conclusive. The influence of these factors appears to vary with the disorder. In post-traumatic stress syndrome, such factors play a major role, whereas in obsessive- compulsive disorder, brain chemistry appears to be the primary culprit.

Psychopharmacology, the treatment of psychiatric disorders and emotional distress with medication, has developed over the last fifty years, as our understanding of the workings of the brain has increased in sophistication. When medication is prescribed for mental and emotional illness, the most frequent goal is to restore the chemical balance within the brain, thereby restoring equilibrium to the entire system. Certain drugs function to address certain symptoms, such as when sedatives are prescribed for insomnia. Medications can work to slow disease processes, such as when anti-oxidants are used to treat Alzheimer's. Still other drugs control cravings and curb other problematic behaviors, such as taken to control alcoholism.

Medication is most helpful when there is clear disorder or, sometimes, a specific target symptom for a particular drug. Usually, a pattern of symptoms point to a specific chemical imbalance. Whenever an imbalance appears evident through a person's disordered behavior and emotional state, medication centers on modifying the strength of the signal or readjusting the balance among them.

The human skin and modern skin care

The skin is often known as "the largest organ in the human body". This applies to exterior surface, as it covers the body, appearing to have the largest surface area of all the organs. Moreover, it applies to weight, as it weighs more than any single internal organ, accounting for about 15 percent of body weight. For the average adult human, the skin has a surface area of between 1.5-2.0 square metres, most of it is between 2-3 mm thick. The average square inch of skin holds 650 sweat glands, 20 blood vessels, 1000 melanocytes, and more than a thousand nerve endings.

The constantly peeling off dead cells of the epidermis mix with the secretions of the sweat and sebaceous glands and the dust found on the skin to form a filthy layer on its surface. If not washed away the dirt and dead skin slurry begins to decompose emitting a foul smell.

Functions of the skin are disturbed when it is dirty and it becomes more easily damaged. The release of antibacterial compounds decreases. Dirty skin is more prone to develop infections. Cosmetics should be used carefully because these may cause allergic reactions. Each season requires suitable clothing in order to facilitate the evaporation of the sweat. Sunlight, water and air play an important role in keeping the skin healthy.

The skin supports its own ecosystems of microorganisms, including yeasts and bacteria, which cannot be removed by any amount of cleaning. In general these organisms keep one another in check and are part of a healthy skin. When the balance is disturbed, e.g., by antibiotics which kill bacteria, there may be an overgrowth and infection by yeasts. The skin is continuous with the inner epithelial lining of the body at the orifices, each of which supports its own complement of flora.

The most important way to care for your skin is to protect it from the damaging rays of the sun. Ultraviolet radiation damages the skin and can lead to wrinkles, premature aging, age spots, and cancer. Take extra precautions to make sure your skin is not exposed to the sun's rays. Use a natural sunscreen, or a moisturizer that contains sunscreen (at least SPF 15) everyday. Your skin does need some sunlight 10-15 minutes of direct exposure daily.

Wash your skin thoroughly on a daily basis to remove the dirt, debris, pollutants, and perspiration that accumulates on a daily basis. If you have dry or sensitive skin, use only warm water to wash your skin and use a mild natural cleanser every few days. If you have normal or oily skin, be sure to wash with a gentle cleanser on a daily basis. Be sure to brush your teeth before washing your face, as toothpaste residue can irritate sensitive facial skin.

Healthy body through weight loss

Fasting diets for weight loss may be right for obese persons who have serious weight-related medical problems. Rapid weight loss is the primary advantage of using these diets. This may be helpful in motivating the individual to continue with the program. This may help to support lifestyle changes which are needed for continued weight loss.

During a binge, 10,000 to 20,000 calories can be consumed throughout the day. Binges usually consist of foods like cookies, candy, chips, ice cream and many other high calorie foods. Binges are often done in secret. After a binge, many of the feelings that caused the binge, like stress, may have subsided only to be replaced with feelings of guilt and lack of self-control.

Obesity often is viewed as the result of a lack of willpower, weakness, or a lifestyle "choice" - the choice to overeat and under exercise. The belief that persons choose to be obese adds to the hesitation of health professionals and patients to accept the use of long-term appetite suppressant medication treatment to manage obesity.
