8 Tips for Nighttime Cough Relief

Nighttime coughs can be sleep-wreckers. The key is to soothe your ticklish throat and over-sensitive airways before you go to bed.

Drink herbal tea with honey. Get into the habit of having a mug of non-caffeinated tea before bed. "Any warm liquid can help break up mucus in your airways," says Norman H. Edelman, MD, chief medical officer of the American Lung Association. Add a little honey. 

Sleep on an incline. When it comes to nighttime cough, gravity is your enemy. All the postnasal drainage and mucus you swallow during the day backs up and irritates your throat when you lay down at night. Try to defy gravity by propping yourself up on some pillows while you sleep.

Another trick for people with acid reflux is to stick wooden blocks under the head of the bed to raise it 4 inches. With that angle, you might keep acids down in your stomach where they won't irritate your throat. Of course, you'll have to get your partner's OK first.

Use steam cautiously. Dry airways can make your cough worse. You may find relief from taking a shower or bath before bed -- or just sitting in a steamy bathroom. Edelman has one caution: "If you have asthma, steam can actually make a cough worse."

Watch the humidity. Humidifiers can help coughs if the air is dry. But too much moisture in your bedroom can keep you coughing, too. Dust mites and mold -- both common allergens -- thrive in damp air. Edelman suggests that you keep humidity levels at 40% to 50%. To measure humidity, pick up an inexpensive device -- a hygrometer -- at your hardware store.

Prepare your bedside. In case you start coughing in the night, have everything you need by your bed -- a glass of water, cough medicine or drops, and anything else that seems to help. The sooner you can stop a coughing fit, the better. Continually coughing irritates your airways, which can make your nighttime problem last longer.

Keep bedding clean. If you have a cough and are prone to allergies, focus on your bed. Dust mites -- tiny creatures that eat dead flakes of skin and lurk in bedding -- are a common allergy trigger. To get rid of them, each week wash all your bedding in hot water, Edelman says. You may also want to wrap your mattress and pillows in plastic, as that can keep dust mites from invading.

Consider medicine. Over-the-counter cough medicines can help in two ways. An expectorant can help loosen mucus. A cough suppressant blocks the cough reflex and reduces the urge to cough. Look carefully at the label to make sure you get the medicine that's right for your cough. Ask your pharmacist or doctor if you're not sure.

See your doctor. If you've had a nighttime cough for longer than 7 days, it's time to check in with your doctor. It may take some time, but together, you and your doctor can figure out the cause -- and make your nights peaceful again.

The Truth About the Common Cold

How long can germ live on your bathroom sink?

Germs can survive up to three hours on objects like your bathroom sink, the kitchen counter, and that doorknob your preschooler just touched after wiping his nose without a tissue. If someone in your house has a cold, you may be able to stop spreading it by wiping surfaces with a virus-killing disinfectant.

Colds are actually most contagious before symptoms appear and during the first 2-4 days after symptoms start to appear. You don't have to hide in a bubble, but try to avoid close contact with others when you have a cold and be sure to wash your hands frequently. Cover your mouth with a tissue or handkerchief when you sneeze or cough -- or use the crook of your elbow. (You don't usually touch people or objects with your elbow, so you're less likely to spread germs than if you cover your mouth with your bare hand.)

What causes colds?

There are more than 200 viruses that cause colds, with rhinovirus being the most common. Colds arenot caused by bacteria, which means that antibiotics -- designed to treat bacterial infections -- are useless against them. Treating a cold with antibiotics not only won't work, it can be hazardous.

"Don’t go out with that wet head, you'll catch your death of cold!" Despite Mom's warnings, going outside with wet hair or without a hat doesn't put you at greater risk of catching a cold. You might becold and uncomfortable, but colds are spread by germs, not the temperature.

People get more colds in winter because Colds are spread by close contact, and in the winter we spend a lot more time inside, keeping warm. That means we're more exposed to other people -- and their germs. Winter air is also much drier than the air in spring and summer, and cold viruses tend to thrive in low humidity. (Running a humidifier in your bedroom during the coldest winter months can help with cold symptoms.)

Some people swear by vitamin C or echinacea. But there is very little proof that vitamin C has any effect on the average person with a common cold. Studies have shown that very high doses of vitamin C may reduce your chance of getting a cold, but only under certain circumstances. High doses of vitamin C can also hurt the kidneys and cause nausea and diarrhea.

Echinacea is one of the best-selling herbal products in the U.S., but many researchers believe there is no proof that it has a benefit for people with colds.

What is the best treatment when you have a cough?

The best remedy for a preschooler's cold is an old-fashioned one: stay in bed and get plenty to drink to stay hydrated. Over-the-counter cold and cough medications should not be given to children under age 4. There’s no evidence that these medicines help children. Some believe the possible benefits are not worth the risk.

Grandma was right: Chicken soup can help relieve a cold?

It's not just Grandma's tale: Chicken soup helps break up nasal congestion and ease stuffiness. Some studies suggest that it inhibits the inflammatory response that leads to a sore throat. And when you're feeling run-down, the combination of lean protein and vegetables can help boost your strength to fight off illness.

What is the best way to prevent a cold?

The best way to keep from catching or spreading a cold is by washing your hands thoroughly and regularly. Wash hands frequently, and here's how: Wet your hands first, then apply soap, and scrub forat least 20 seconds. Singing "Happy Birthday" all the way through two times takes about 20 seconds. Hand sanitizers can also be a good supplement to handwashing.

Children get between 6 and 10 colds every year -- including spring and summer -- so it's not unusual for your child to be sniffling and sneezing every other month, or even more often. If they are in day care, preschool, or other settings where they spend a lot of time with other kids, they'll be exposed to lots of germs, and regular colds aren't necessarily something to worry about.

It's probably a flu -- not just a cold--- if you have a high fever: Some people do run a slight fever along with a cold, but if you have a high fever it's more likely the flu or a complication. Fatigue, while more common with the flu, also is seen with colds.

It's not just your yoga teacher trying to persuade you to take another class: Studies have found that people are more susceptible to catching colds when they're under stress. Vulnerability appears to be linked to chronic stress that lasts more than one month, like trouble at work or problems in your family relationships.
