Antioxidants: Antioxidants, such as vitamin E, vitamin C, or beta-carotene, are thought to protect the body's cells from the damaging effects of free radicals. A diet rich in antioxidants has been suggested as a possible anti-aging treatment. Exercise: Regular exercise may decrease an individual's risk of developing potentially fatal or debilitating medical conditions, such as heart disease, cancer, or diabetes. Exercise is any form of physical activity that helps to promote overall health. Most movement of the body is considered beneficial, as long as it is done in moderation and at the skill level of the person. Current opinion finds regular exercise to boost energy, encourage healthy sleep patterns, and help individuals maintain a regular weight. All major medical organizations recommend exercise as one of the most important ways to stay healthy and recover after illness. There are many ways for people to exercise, including gardening, walking, sports activities, and dancing. Patients who are beginning an exercise program should choose activities that fit their levels of strength and endurance. The type of exercise is not as important as a consistent exercise schedule. Most experts today agree that burning calories should not be the goal of exercise. Exercise that causes extreme pain or discomfort is considered by many experts as harmful, and it may even cause permanent damage to the body. Healthy diet: Eating a healthy and well-balanced diet may also help individuals live longer, healthier lives. The U.S. government issued a revised food pyramid in 2005 in an effort to help Americans live healthier. The new pyramid provides12 different models based on daily calorie needs. Current research suggests that a low-calorie diet with the required nutritional content may delay human aging. According to animal studies, a low-calorie diet, ranging from 1,400 to 2,000 calories, may lead to a 50% increase in life expectancy. However, a low-calorie diet is not for everyone, especially those who exercise rigorously. Therefore, individuals should consult their healthcare providers and/or nutritionists before starting a low-calorie diet. Red wine in moderation (about one glass a day) has been suggested as having anti-aging effects. Red wine contains a substance called resveratrol, which has been shown to mimic the effects of a low-calorie diet in laboratory studies. Researchers believe that resveratrol fools the body into thinking it is being deprived of food. As a result, the genes that repair DNA are activated and the aging process is slowed. Hormone replacement therapy (HRT): The human growth hormone (hGH) has been suggested as an anti-aging treatment. This hormone is naturally produced by the body's pituitary gland to stimulate growth. Researchers are currently studying the hormone to determine if it can delay the aging process. It has been suggested that hGH may reduce signs of aging by increasing muscle mass, strengthening the immune system, and increasing libido. However, further research is warranted to determine the safety and effectiveness of this treatment. Currently, the U.S. Food and Drug Administration (FDA) has not approved the use of hGH as an anti-aging treatment. Lifestyle: Individuals can make lifestyle changes to delay aging. Research has shown that individuals who are able to manage their stress levels are able to live longer, healthier lives than those who do not. Individuals should not smoke because the toxins in cigarette smoke promote free radical damage, which may speed up aging. Individuals should consume alcohol in moderation. Research has shown that individuals who have the support of friends, family members, spouses, and/or significant others are more likely to live longer, healthier lives than those who do not. Retinol: Retinol lotions, gels, serums, peels, creams, and make-up removal products may help prevent wrinkles. Vitamin A is the active ingredient in retinol. Vitamin A has been shown to increase collagen and elastin formation in the skin. This helps minimize fine lines, wrinkles, and sagging skin. Sunblock: Protecting the skin from sun exposure can help prevent wrinkles and age spots associated with aging. Patients should choose a sunblock with a sun protection factor (SPF) of 15 or higher. The sunblock should offer protection against both ultraviolet A (UVA) and ultraviolet B (UVB) rays. Patients can wear hats with brims, sunglasses, and protective clothing when outside to minimize sun exposure. An umbrella or parasol may also help block sunrays.
