Mental Attitude: Tinnitus Affects How Sufferers Process Emotions.
Tinnitus is a condition in which patients hear noises that aren’t really there such as ringing, whooshing, whistles, and whines. According to experts, individuals with persistent tinnitus are more likely to experience increased stress, anxiety, irritability, and depression. To investigate how tinnitus affects the brain, researchers evaluated brain responses to different emotions by individuals both with and without tinnitus using functional magnetic resonance imaging. When compared to participants with normal hearing, they found tinnitus patients had decreased brain activity in the amygdala, the area of the brain that processes emotion and stress; however, they had increased activity in the parahippocampus and insula, areas of the brain that are also associated with emotions. This indicates that in order to cope with the stress of persistent noise, the brains of tinnitus patients have reduced activity in the amygdala and rerouted some of its functions to other regions.

Health Alert: Serious Allergic Reactions with Some Acne Products.
The Food and Drug Administration has issued a warning to consumers who use certain over-the-counter skin products for acne due to the risk of extreme allergic reactions. The active ingredients benzoyl peroxide or salicylic acid are suspected to cause these reactions, which can include feeling faint, breathing difficulties, throat tightness, and swelling of the eyes, lips, face, and tongue. Products containing the active ingredients benzoyl peroxide or salicylic acid are available as face washes, solutions, cleansing pads, gels, lotions, toners, and face scrubs. The FDA recommends consumers to stop using products containing these ingredients if they develop hives or itching.

Diet: Fruits & Veggies May Not Help Weight Loss.
Adding more servings of fruits and vegetables is often recommended for individuals trying to lose weight, but according to researchers, doing so may not help them shed excess pounds. A review of seven studies found that increasing fruit and vegetable intake without reducing total calories consumed appears to have a near-zero effect on weight loss. Researcher Dr. Kathryn Kaiser adds, “In the overall context of a healthy diet, energy reduction is the way to help lose weight, so to reduce weight you have to reduce caloric intake.”

Exercise: Exercise Improves Body Composition for Kids.
A recent study referred to as “FITKids” demonstrated the extent to which physical activity can improve body composition, which is important as it contributes to overall health. The study included 220 eight- to nine-year-olds who were assigned to either a nine-month physical activity program that required 70 minutes of moderate to vigorous physical activity five days a week or a control group. Researchers measured baseline and follow-up cardiorespiratory fitness, percent fat mass, percent central fat mass, and estimated abdominal fat tissue. The FITKids showed improved cardiovascular fitness, less body fat, and carried less fat around their abdomens. The opposite was true for the control group who maintained their regular after-school routine.

Chiropractic: Strong Support for Manual Therapy to Treat Back Pain.
Two independent reviewers analyzed data from 360 studies published between 2000 and 2013 related to the use of manual therapies — such as chiropractic care — to treat acute, subacute, and chronic non-specific low back pain. For all levels of low back pain, the reviewers found strong evidence for the use of manual therapy to both decrease pain and improve function.

Wellness/Prevention: Keep Teens Safe During Sports.
Participating in sports is a key part of many children’s high school experience, but injuries can and do occur. The American Academy of Orthopaedic Surgeons suggests the following ways to reduce the risk of sport-related injuries: wear protective equipment, ensure proper training and conditioning, build strength and stamina, follow rules and practice good sportsmanship, play only one sport per season, and don’t play just one sport all year-long.
