You stumble to the kitchen and pour yourself a cup of coffee ambition as part of your daily routine. Should you try to kick the habit? Not according to new studies, which show java benefits ranging from weight loss to reduced diabetes risk to tinnitus prevention, reported Medical Daily on August 10.
Tinnitus consists of ringing in your ears or noise in your ears. When researchers from Brigham and Women’s Hospital (BWH) in Boston analyzed the benefits of caffeine for more than 65,000 healthy women, they found that women who drank about five cups a day were 15 percent less likely to develop tinnitus.
But the precise reason is to be determined, said Dr. Gary Curhan, study co-author and a physician-researcher in the Channing Division of Network Medicine at BWH. "We know that caffeine stimulates the central nervous system, and previous research has demonstrated that caffeine has a direct effect on the inner ear in both bench science and animal studies."
The challenge in comprehending the link between caffeine and tinnitus lies in the multiple causes for the condition. For example, it can result from broken or damaged cilia (hair) on the auditory cells of the inner ear, turbulence in a carotid artery or jugular vein or even temporomandibular joint (TMJ) problems, reported the Daily Digest News on August 10.
Because it typically impacts women, the new study does contain hope for those for whom other treatments have failed. However, tinnitus can also be caused by the initial signs of hearing loss or even an injury. One in five people have the condition.
The researchers plan to conduct additional studies to investigate how caffeine can help to control tinnitus. One problem in telling people with the condition to dash out and drink up: That much coffee is considered hazardous to your health, reported the Atlanta Journal Constitution on August 9.
The Mayo Clinic warns that sipping four or more cups of regular coffee daily can cause anxiety, stomach problems and insomnia. One study linked a shorter life expectancy to drinking that much coffee.
However, for those with tinnitus, the new study does offer hope in preventing what can become a frustrating condition. Moreover, other studies have shown that drinking coffee has additional benefits.
One study, for example, found that drinking three to four cups of coffee per day can help prevent type 2 diabetes. Another study, published in the journal Diabetologia, revealed that by increasing your coffee intake by more than one cup a day, you can reduce your risk of type 2 diabetes by 11 percent.
Coffee also can help with weight loss, according to Dr. Mehmet Oz. It can increase energy expenditure, speed up your metabolism and suppress your appetite.
Other studies have shown that caffeine intake can promote weight loss via fat oxidation and thermogenesis. In one study, reported in the Obesity Research Journal, researchers found that mixing green tea with caffeine helped to maintain weight due to those factors.
