Tips to manage tinnitus

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.

Your brain on high blood pressure

High blood pressure not only can raise risk for a heart attack, but also can affect the brain. Keeping blood pressure normal can make brain injury from stroke less likely to happen and perhaps slow the natural decline in cognitive function. Just like with the heart, the best way to protect the brain from high blood pressure is to lower blood pressure if it's high and keep it as close to a normal level as possible.

The big pain of small-fiber neuropathy

People sometimes experience a sudden tingling or numbness in the feet or hands that goes away. But if the problem keeps occurring, followed by painful or burning sensations, this could be a sign of small-fiber neuropathy. While not life-threatening, small-fiber neuropathy should always be checked out, as it could be a symptom of something more serious.

Do allergies make snoring worse?

Allergies that cause nasal congestion, sneezing, and a runny nose (what doctors call allergic rhinitis) can cause more frequent and louder snoring. Treating allergic rhinitis can reduce snoring and other symptoms related to poor-quality sleep.

Fish linked to lower risk of vascular brain disease

Older adults who eat fish several times a week may be less likely to develop early signs of cerebrovascular disease, a category that includes strokes, aneurysms, and related problems.

Anger or emotional upset may trigger stroke

Anger or emotional upset may be linked to an increased risk of stroke within an hour of experiencing those negative emotions.

The heart-related hazards of air pollution

Air pollution is an often overlooked yet important contributor to cardiovascular disease. Tiny particles known as PM2.5 travel deep into the lungs, where they irritate receptors and trigger nerves involved in the autonomic nervous system. This irritation also contributes to inflammation, which accelerates atherosclerosis. Climate change can worsen the damaging effects of air pollution in several ways, such as by promoting wildfires and dust storms, which creates more PM2.5. To reduce pollution's harmful effects, people can check air quality information and use portable indoor air cleaners when pollution levels are elevated.

Adding potassium and subtracting sodium may equal better heart health

Consuming less sodium and more potassium may be linked to better heart health, according to a November 2021 study published in the New England Journal of Medicine. After controlling for other risk factors, the researchers found that for every extra 1,000 milligrams (mg) of sodium detected in the urine, there was an 18% increase in the risk of cardiovascular disease. For every extra 1,000 mg of potassium in the urine, there was an 18% decrease in risk.
