Antibiotics often don't help inflamed sinuses. Take steps to ease symptoms and let the problem heal itself.

The hollow spaces in your facial bones—the sinuses—are prone to infection by microorganisms of various stripes. Usually, the invader is a virus. In response, the sensitive linings of the sinuses swell up and start to pour out mucus, triggering nasal stuffiness, a runny nose, and facial pain.

Once upon a time, many sinus sufferers headed straight to their doctors to get an antibiotic. But we now know that strategy is usually a waste of time. Most cases of sinusitis are associated with viral infections, which are bulletproof to antibiotics. According to a research review by the Cochrane Collaboration, 80% of people with sinusitis improve within two weeks without taking antibiotics.

It may be as simple as adjusting the dose, avoiding alcohol, or taking the drug at a different time of day.

One of the most commonly reported side effects of some medications is drowsiness. "Many people report tiredness or fatigue as a side effect from their medicines. However, there are things you can do to minimize the feelings of daytime sleepiness," says Laura Carr, a pharmacist at Harvard-affiliated Massachusetts General Hospital.

Typical offenders

Common culprits that cause sleepiness include antidepressants; antihistamines, found in sleep aids or medicines that treat allergies; anti-emetics, which are used to control nausea and vomiting; antipsychotics and anticonvulsants, which can be used to treat seizures or depression; drugs to treat high blood pressure, including alpha blockers and beta blockers; benzodiazepines and other sedatives, which are commonly used for anxiety or insomnia; drugs for Parkinson's disease; muscle relaxants; and opioids and other prescription pain medications. Many over-the-counter medicines may also make you drowsy, such as remedies for insomnia, allergies, nausea, vomiting, or diarrhea.

Q. I often wake up with a sore neck in the morning. What can I do to prevent this?

A. Poor sleep habits can cause neck pain or make it worse. Simple changes can make it less likely that you will wake up in pain in the morning.

Sodium doesn't affect everyone equally, but there's good reason to stick to moderate amounts in your diet.

On average, Americans eat too much salt — more than a teaspoon and a half a day. Most often it doesn't come out of a shaker, but is hidden in the foods you eat. But is it really bad for your heart to eat too much, or is that just a concern for people with certain risk factors? There's been some debate on this topic, even among members of the scientific community. We asked Nancy Cook, a professor of medicine at Harvard Medical School, for her thoughts on salt — or more precisely, sodium, a mineral that makes up 40% of salt — and how it affects your health and your heart.

Is salt really bad for your heart?

"There is a fairly undisputed effect of sodium on blood pressure," says Cook. The effect is stronger in people with high blood pressure (hypertension), a sustained blood pressure reading of 120/80 or higher. The data for an effect on cardiovascular disease are somewhat more controversial, she says, but in general, the bulk of research does seem to link lower sodium intake with both lower blood pressure and a lower risk of cardiovascular disease.

Whole grains contain fiber and nutrients that can help your health.

It's a low-carb world, and many people are pushing grains off their plate in an effort to control their waistline. But they may be doing their body a disservice. Whole grains have some unique properties that make them a valuable addition to the diet. Not only do they contain a host of nutrients, such as iron, B vitamins, copper, zinc, and magnesium, but studies have linked diets rich in whole grains to a lower risk of colon cancer, which is a growing health threat for many younger Americans.

"The main benefit of whole cereal grains, such as wheat, oats, and barley, is in the fiber," says Teresa Fung, adjunct professor in the Department of Nutrition at the Harvard T.H. Chan School of Public Health. "Cereal fiber is different from vegetable fiber or bean fiber."

Do you know someone who is taking supplements in hopes of boosting their energy levels, gaining muscle, or losing weight? You may want to warn them about potential dangers. A study published online June 5, 2019, by the Journal of Adolescent Health found that products sold to boost energy, promote weight loss, or build muscle were linked to three times the number of severe medical events compared with vitamins. Researchers came to this conclusion after looking for supplement-related adverse events reported between January 2004 and April 2015 to the FDA. In total, they identified 977 cases of harm linked to supplements. Of those, 40% were severe medical events that resulted in death or hospitalization. While energy, weight loss, and muscle-building supplements appeared to be the riskiest, products sold to promote sexual function or to cleanse the colon were problematic as well. The FDA has found that some of these supplements contain dangerous substances or contaminants, such as pesticides, harmful chemicals, or heavy metals. Past studies have connected weight-loss and muscle-building supplements with serious, sometimes fatal, health problems, including liver damage, stroke, and testicular cancer.

If the contents of your lunch bag are looking less than wholesome, you're not alone. A survey sponsored by the American Heart Association found that more than half of Americans who eat lunch at work reported that their midday meal often falls short when it comes to good nutrition. In addition, 91% of those surveyed said they would be interested in making healthier lunch choices. So, what's making people choose less healthful lunch options? Top reasons included the convenience of unhealthy foods (cited by 60% of respondents), taste (54%), and a lack of healthy food options (cited by 43%). If you're looking to improve your own lunch quality, the American Heart Association offers some tips on its website at www.heart.org/healthyforlife.

Q. My smartphone tells me how many steps I take each day, but I don't know how many I should shoot for. What should my goal be?

A. You've read in these pages and elsewhere that regular physical activity reduces the risk of heart disease, type 2 diabetes, obesity, and possibly several types of cancer. Regular exercise also reduces the risk of premature death. No medicine yet invented can claim such benefits. Probably the advice you've heard most often is that moderate exercise — like a brisk walk (at about 3 mph) for 30 minutes at least five times a week — will bring all of the above health benefits.

Bacteria and mold can accumulate in various parts of the device. But regular equipment cleaning reduces risks.

Continuous positive airway pressure (CPAP) can be hard to get used to. The mask may feel bulky, or it may feel strange to have air blowing in as you try to breathe. That keeps many people from using a treatment that may, in fact, be a lifesaver (see "What is CPAP?").

People also can be put off because they've heard that a dirty CPAP machine can make you sick. Is that true? "Yes, if you don't clean the machine regularly," says Dr. Lawrence Epstein, a sleep expert at Harvard-affiliated Brigham and Women's Hospital.

The proper warm-up, equipment, and health considerations are key to maintaining an outdoor routine.

You've grabbed a hooded jacket, and you're ready for a brisk walk in the great outdoors. But is that enough to keep you safe in cooler temperatures? An outdoor exercise routine at this time of year brings unique risks and benefits. You need a little planning and preparation to keep exercising outside in the weeks or months to come.

Know the risks

Being exposed to long periods of cold weather poses numerous health risks.
