While frightening, fainting is not always serious, though it’s important to be aware that it may be a sign of an underlying problem with the blood vessels or heart.

People concerned about sodium intake should be careful when dining out, as many restaurant meals are loaded with salt, and it’s not just the fast-food places that are guilty of this.

A five-year study of more than a quarter of a million commuters in the United Kingdom found that those who commute to work by bicycle had lower risk of cardiovascular disease and cancer, or of dying from any cause.

Of all the flavors in the world, we choose salty — and that’s not good

The average American consumes three times the recommended daily intake of sodium, largely because of salt added to processed and prepared foods. It’s possible to reduce daily sodium intake, but it does require effort and vigilance.

A large, long-term study confirms that running decreases a person’s overall risk of death, and while the benefits from other forms of physical activity are not as significant, any activity is still better than none.

Not everyone who has a heart attack experiences chest pain. Sometimes pain is felt elsewhere, or the person has non-pain symptoms such as dizziness or nausea, or a higher pain tolerance could mean a person is unaware that an attack is happening. Nonclassic symptoms tend to occur slightly more frequently in women and older people.

The health benefits of coconut oil remain unproven and there is no evidence that consuming it lowers the risk for heart disease. Results of studies of populations in parts of India, Sri Lanka, the Philippines, and Polynesia who consume large amounts of coconut must be tempered with the fact that these traditional diets include more healthful fish, fruits, and vegetables than the typical American diet. That said, it’s fine to enjoy foods prepared with coconut oil provided they are occasional treats.

With a study showing that 400,000 cardiovascular-disease deaths could be prevented each year with dietary changes, it’s time to consider adopting a healthier eating approach. Limiting unhealthy foods is a good start, but it’s also important to eat more healthful foods.

During the holiday season it’s not difficult to overindulge and too much alcohol. There’s a well-established connection between binge drinking and atrial fibrillation or afib, an irregular heart rhythm that can increase the risk of a stroke. It’s known as holiday heart syndrome. A recent study suggests that even more moderate alcohol consumption may increase the risk.
