AUDIBEL PROMOTES HEARING HEALTH

According to hearing health providers, nearly one in five Americans age 12 years and older – 48 million people – experience hearing loss severe enough to hinder communication. Hearing loss is the third most prevalent age-related disability in adults age 75 years plus, following arthritis and hypertension. Only 5 percent of hearing loss in adults can be improved medically or surgically. The vast majority of Americans with hearing loss are treated with hearing aids.

TAKING CARE OF YOUR AGING SKIN

As you age, you may notice wrinkles and brown spots on your skin. Aging makes skin more prone to dryness. Your skin also becomes thinner and loses fat, making it less plump and smooth. Cuts and bruises might take longer to heal. How skin ages will depend on several factors: your heredity, lifestyle, diet and other personal habits, such as smoking. Sunlight is another major cause of skin aging.

A GOOD NIGHTS SLEEP IS GOOD FOR SENIOR HEALTH

For some seniors,getting a good night’s sleep is an everyday challenge. Some sleep specialists recommend seniors sleep about seven and a half hours on average, while others say seniors need to get as much sleep as they always have to function at their best. The National Sleep Foundation (NSF) convened experts from the fields of sleep research, anatomy and physiology as well as pediatrics, neurology and gerontology to reach a consensus from the broadest range of scientific disciplines.

All types of aerobic exercise qualify, even dancing, which is said to beat traditional exercise when it comes to improving older adults’ balance and may enhance brain areas related to memory and learning. More research is needed to judge the effects of exercise on the brain for those who are already cognitively impaired and for the already frail individual. But the message is clear: For big brain benefits, get in your exercise most days of the week. Mark it on your calendar and just do it, whether it is walking, biking or some other form of movement. Your body – and your brain – will thank you.

Exercise offers neurobiological benefits, too, such as helping to reduce stress. An experiment was performed on mice who exercised and mice who did not. The researchers concluded exercise reorganizes the structure of the brain to react differently to stressful situations by reducing the excitability or firing of neurons. Exercise helped reduce the level of anxiety the mice that exercised felt when experiencing stress. There was less or no reduction of stress in the mice that were sedentary.


Exercise increases energy and reduces fatigue. It was found to ramp up the creation of new mitochondrial cells in the brain, which can help guard against mental fatigue. It slows down degenerative changes in the brain, thereby reducing brain atrophy. After age 30, the brain loses volume, specifically in the hippocampus. This affects cognitive abilities. Researchers discovered moderate exercise in healthy older adults actually reversed brain aging by helping them gain 1 percent to 2 percent volume in the hippocampus. Exercise seems to create a lowered risk for dementia and Alzheimer’s disease. It increases productivity, boosts creativity and jumpstarts learning.

While exercise has long been known for its positive effects on physical health and its ability to heighten energy and help manage chronic health problems such as diabetes, hypertension and high cholesterol, exercise is now being lauded for its beneficial effects on the brain.


These benefits touch almost every aspect of life. Exercise helps sharpen short-term memory and improve long-term memory. This happens because exercise can reduce insulin resistance and inflammation and stimulate the release of chemicals that promote the growth of new blood vessels in the brain. It can even affect the abundance and survival of new brain cells. Exercise increases focus and cognitive flexibility. In a 2009 study, researchers found there is a link between aerobic exercise and increases in mental speed, attention and cognitive flexibility.


Psychological benefits of exercise abound. It has the ability to restore positive feelings and make you resistant to stressful situations. Neurochemicals are released into the brain during exercise. The chief ones are endorphins, dopamine and norepinephrine. These are “feel good” chemicals that help clean out stress hormones such as cortisol and adrenaline from the body. Exercise positively impacts self-esteem and counteracts depression. In many individuals, exercise has been shown to increase pain tolerance. And exercise makes you happier. In a long-term study, researchers found people who were active tended to be happy and remain happy, whereas people who were not active often failed
