A 2022 study suggests that sleep irregularity—night-to-night variations in sleep duration and timing (when someone falls sleep)—are linked to atherosclerosis (plaque buildup in the arteries).

For many people, attacks of vertigo recur periodically. The attacks are usually caused by a disorder of the balance (vestibular) system. Examples of balance disorders include benign paroxysmal positional vertigo (BPPV), cervical vertigo, Meniere's disease, and vestibular migraine. Treatment for recurring vertigo involves getting the underlying cause under control; seeking physical therapy tailored to people with balance disorders; and (for people with BPPV) doing a particular maneuver to reposition loose debris in the ear canal.

Unlike a few decades ago, there are now a number of minimally invasive ways to treat varicose veins. Doctors can shut down problem veins with injections of various substances or certain catheter procedures. A treatment currently in clinical trials in the United States promises to simply "zap" away varicose veins from outside the body. Called high-intensity focused ultrasound, it converts sound waves into a focused beam of heat that seals a malfunctioning vein.

Daily persistent nasal drip or congestion is usually caused by chronic nonallergic rhinitis. Daily nasal irrigations and prescription nasal sprays are the recommended treatments.

A 2023 study suggests that certain social challenges, such as isolation, may be useful to help predict older adults' risk of earlier death.

A 2023 study suggests that women who practice many aspects of a healthy lifestyle are about half as likely as women who don't to experience persistent symptoms after a COVID-19 infection.

Many factors can increase heart rate from the normal pace of 60 to 100 beats per minute. Lifestyle choices and certain medications can raise heart rate, as can serious conditions. When an elevated heart rate is joined by urgent symptoms, seek immediate care.

"Brain freeze" happens when people eat ice cream or other cold treats, drastically dropping the temperature at the back of the mouth. This results in rapid changes in blood vessel size, sending pain signals to the brain. Brain freeze typically disappears within 30 seconds.

Two studies found that managing stress and eating a plant-based diet with at least seven servings of leafy green vegetables per week can help improve cognitive function and protect against Alzheimer's disease, respectively.

First-line gout treatment focuses on reducing pain and inflammation. Ideally, treatment should begin within 24 hours of the start of the gout attack. Treatment is stopped once the attack is over, and symptoms have gone away.
