SLEEP:
Developing muscle growth is an effective way to stay healthy as we get older, but many people find it difficult to develop this muscle growth, even after modifying their exercise routine and food intake. What many people may not realize is that getting the proper amount of uninterrupted sleep plays a major role in the development of muscle. The hard work of developing muscle is done in the gym, on a track, or on the court, but the actual growth takes place during the rest periods that follow a workout. Your body immediately begins rebuilding the muscle fibers that were broken down during the course of your workout. Much of this process is carried out while you are sleeping, so without a full night of sleep, muscle fibers will not have the opportunity to rebuild.
Human growth hormone (HGH) is an amino acid that is central to regulating metabolism, building muscle, facilitating calcium retention, and stimulating the immune system. The amount of HGH in your body spikes significantly during deep sleep, which makes getting at least 7 to 10 hours of sleep every night imperative to anyone hoping to develop additional muscle growth. Recent studies have linked inadequate amounts of sleep to lowered levels of leptin, a hormone in the brain that controls appetite. Test subjects who received less sleep, or frequently interrupted sleep, would crave carbohydrates even after their caloric needs reached satiety. This can contribute to obesity and negatively affect any good habits people may have developed with regard to food intake.

HCFS:
The impact of high fructose corn syrup (HFCS) on health has been a topic of concern in recent years. High fructose corn syrup, a sweetener derived from corn, has been linked to various health issues, including obesity. Unlike refined table sugar, which is a natural product, HFCS is manufactured through a chemical process. Studies have shown that rats tend to prefer HFCS over other sweeteners, raising questions about its effects on human health. The American Medical Association (AMA) has examined the implications of HFCS consumption and its potential role in the obesity epidemic. Despite some benefits in terms of cost and versatility in food products, the association has highlighted potential health risks, including increased caloric intake and potential links to obesity. As research continues, the debate over the safety and health implications of HFCS remains relevant.

The Long-Term Impact of Toxic Exposure:
Lie out in the sun too much today�and get skin cancer 20 years from now. Smoke too many cigarettes now�and get lung cancer decades down the road. Now there is potentially a third danger to add to this list: be exposed to too much lead, pesticides, or mercury now and have your aging brain become seriously confused during your senior years.
�We�re trying to offer a caution that a portion of what has been called normal aging might in fact be due to ubiquitous environmental exposures like lead,� says Dr. Brian Schwartz of Johns Hopkins University. �The fact that it�s happening with lead is the first proof of the principle that it�s possible.� A new area of medical research is one that studies how exposure to toxic elements in younger years can result in serious health problems in senior years.
It is difficult to research these problems because the only way to do so is to observe people over many years. Physicians test for lead amounts by seeing how much has accumulated in a person�s shinbone. Testing the blood also often reveals amounts of lead, but that is a sign of recent, not lifelong, exposure. The higher the lifetime lead dose, according to the study, the worse the performance of mental functions, including verbal and visual memory and language ability.

YOGA:
Yoga is an exercise that everyone should try. Yoga was first practiced thousands of years ago. It helps connect the mind and body by taking a person through a series of poses while emphasizing controlled breathing and meditation.
Every year hundreds of thousands of people enjoy the benefits of yoga by treating the movements and postures as exercise. Yoga works by safely stretching muscles, ligaments, and tendons. This helps release the buildup of lactic acid in the muscles that can often cause stiffness, tension, and even pain. Yoga helps develop the body�s range of mobility and increases the ease of everyday movements. Many participants report improved flexibility, especially in the trunk and shoulders, after only two months of practice.
Yoga improves posture, balance, and sleep, and it also helps with weight control. Physically, many yoga poses help build upper-body strength, which is increasingly important as the body ages. Other poses help strengthen the muscles in the lower back, and when properly practiced, nearly all of the poses strengthen the body�s abdominal, or core, muscles. This helps improve the circulation of blood that increases the delivery of nutrients and oxygen to the body and also removes wastes produced by the body. When combined with yoga�s benefit of lowering a person�s heart rate, the result is increased cardiovascular endurance.
The University of Maryland School of Nursing recently published a study that showed yoga was especially effective at reducing stress. In addition, researchers found that yoga surpassed traditional aerobic exercise, often significantly, in improving flexibility, pain tolerance, and daily energy levels. One enthusiast says that her advice to skeptics is simple, �Take a deep breath, stretch, and indulge in a few poses. You�ll feel better.�
