Tinnitus is an internal high-pitched ringing, whooshing, or hissing noise. The condition can make it hard to concentrate, reduce sleep quality, and cause irritability, nervousness, anxiety, depression, or feelings of hopelessness. Methods for easing tinnitus symptoms include treatment of underlying conditions, trigger avoidance, hearing aids, sound masking devices, exercise, stress reduction, and social connection. Certain programs can also help reduce tinnitus symptoms, such as cognitive behavioral therapy, group support, and tinnitus retraining therapy.
There are many questions a patient should ask when a new medication is prescribed. Examples include why the medication is needed, what side effects to watch for, whether it might interfere with other drugs, how to take the drug, how long to take it, what to do for a missed dose, how to store it, how much it costs, whether there’s a generic form, what signs indicate the drug is working, and how to get refills.
Chronic stress is bad for health. It can trigger physical problems, including chronic inflammation—the persistent activation of the immune system, which sharply raises the risks for many diseases such as dementia, heart disease, or stroke. Ways to reduce stress include living a healthy lifestyle, doing relaxation exercises, stretching, being mindful, taking a brisk walk, reducing loud noise, using laughter, playing soothing music, countering negative thoughts, reaching out for help from a loved one, and using positive self-talk.

The American Heart Association released updated dietary guidelines in November 2021. Instead of focusing on certain nutrients, the guidelines emphasize healthy eating patterns that include fruits, vegetables, whole grains, plant-based proteins, and plant-based oils. The guidelines also urge people to avoid foods and drinks that are ultra-processed or that have lots of added sugars; to choose or prepare foods with little or no salt; to limit alcohol consumption; and to follow the rules for a heart-healthy diet no matter what the setting.
Exercising is crucial for good health, even if exercising doesn’t help a person get down to a healthy weight. Exercising reduces the risk of high blood pressure, high cholesterol, high blood sugar levels, heart disease, stroke, diabetes, Alzheimer’s disease, and premature death. If someone is overweight and unfit, the risk of premature death is double the risk of someone who is the same age and sex, and is overweight but fit.
Hand pain or stiffness makes computer or smartphone use difficult. Strategies to combat this include stretching the hands and fingers, avoiding awkward hand positions when holding a smartphone or computer mouse, taking breaks, alternating the fingers that do the work, and taking breaks. Using certain tools can also reduce hand strain or pain. Such tools include voice-to-text features, a wide-grip stylus, a smartphone holder, gel-filled wrist rests, and a comfortable mouse (which might be bigger, smaller, or vertical) to keep hands from stretching too wide or gripping too hard.
Vitamin D’s primary function is to help the body absorb calcium, though it may also protect against prostate cancer and other diseases. Many people do not get enough from sunlight, its natural source, and should get the needed amount via a supplement.
