Mistakes You Never Realized Were Making You Even More Sick

Being sick sucks. Whether you have a cold or the flu, you're surely desperate to feel better. We all know the symptoms of these various ailments: sneezing, coughing, stuffy nose, sore throat, headaches. If you've come down with the flu, you may also be dealing with a fever or body aches. You'll probably be in for an uncomfortable seven to ten days with the common cold and three to seven with the flu, according to the Centers for Disease Control and Prevention (CDC). With the flu, you might also have to deal with a lingering cough or feeling rundown for as long as two weeks, the CDC explained.

Even if you manage to dodge the flu by getting the flu shot, the average adult gets a cold two or three times a year, according to the CDC. While we may each have our own tips or tricks to make our symptoms a little more bearable, you might unknowingly be making yourself feel worse. Avoid these common mistakes that could prolong or worsen your seasonal misery.

If you think you can sweat out a fever through exercising, think again. A 2014 review study in the medical journal Sports Health found that working out while "febrile" (having a fever) will only aggravate your illness, not help you get over it faster. Besides, hitting that yoga or spin class when you know you're sick puts others at risk of catching whatever you've got. Don't be that person.

If you're fever-free, the Mayo Clinic says mild or moderate exercise is okay. But walk, don't run — literally — and shorten the length of your activity. Mild exertion could even help relieve some congestion, as long as your symptoms are "above the neck," like nose troubles or sore throat.

If you're feeling funky "below the neck" (i.e., experiencing chest congestion, feel sick to your stomach, or have a gnarly cough), then wait until those symptoms have passed before you resume your regular workout regimen, according to the Mayo Clinic. You should also skip taxing physical activity if you're experiencing muscle aches or fatigue. When in doubt, just don't push yourself.

If you've got an upset stomach or a sore throat, you should steer clear of orange juice. All the acid in citrus juices can irritate the lining of your stomach, especially if you aren't consuming much else while you're sick (via The Healthy). A sore throat is another reason to avoid OJ: The acid can aggravate your already-inflamed gullet, according to Medical News Today. Opt instead for hot teas and soups, which can soothe your throat and hydrate you at the same time — and without all the sugar.

Besides, vitamin C for cold and flu relief may be overhyped. A 2013 review of multiple studies showed that while regular (daily) vitamin C supplementation could lessen the duration and severity of a cold by about 8 percent, taking vitamin C just while you're sick had no similar effect.

If you're determined, though, opt for fresh fruit. Wendy White, a professor of food science and nutrition at Iowa State University, told NPR that eating whole fruit is better because it won't spike your blood sugar like store-bought juice. Still want juice? At the very least, choose juice with pulp, which has more fiber — a nutrient most Americans don't get enough of.

We know you're really going through it, but don't treat your infection like a hangover. Registered dietitian Maryann Tomovich Jacobsen explained in an article for WebMD that foods high in sugar, refined carbohydrates, and saturated and trans fats interfere with proper immune system functions, which will slow down your recovery.

Fried foods contain massive amounts of fat, which can trigger inflammation in the body, clinical immunologist Leonard Calabrese told the Cleveland Clinic. When you're sick, your body is already having an immune response to fight off your infection. That's healthy inflammation. But excessive or prolonged inflammation can cause the body to start destroying healthy cells, making you feel worse, not better, and in the long run can lead to chronic diseases like diabetes or cancer, according to Scripps.

Sugar can actually suppress your immune response, which also means you'll be sicker longer. Niket Sonpal, a board-certified internist and gastroenterologist in Brooklyn, New York, told HuffPost that this suppression can start a half-hour after consuming the equivalent of two cans of soda, and can last up to five hours. Do you really want to add time onto your sickness sentence? We didn't think so.

Should you caffeinate when under the weather? It depends. Registered dietitian Jenny Beth Kroplin told Well+Good that the downside to caffeine is that it's dehydrating, and dehydration is the opposite of ideal conditions for quick recovery. "While you're sick, it's very important to stay on top of hydration to help the body thin mucus [and] replace fluids lost," Kroplin said. Plus, caffeine could interfere with a good night's sleep, and you need adequate sleep if you want your body to produce enough infection-busting proteins and antibodies (via Mayo Clinic).

But if you're feeling on the upswing, coffee may provide you the boost you need to break through your general crumminess, Kroplin said. Coffee also has loads of antioxidants. "Research suggests the antioxidant activity from coffee, specifically from ferulic and caffeic acids, has anti-inflammatory, antibacterial, and antiviral effects," according to Kroplin. "This can all be helpful to the body in healing from an illness."

However, alcohol is a straight up no-no. Physician Michael Albert told Popsugar there is ample evidence that alcohol suppresses our immune systems, even in smaller amounts, which could prolong illness. It can also negatively interact with some over-the-counter medicines. So say no to that hot toddy.

Being completely horizontal, clutching your pillow for comfort, might sound like the only thing you want when the common cold or flu strikes. And getting plenty of sleep is paramount. But you'll feel better if you use those pillows to prop yourself up — especially when you've got the flu, Dr. Patricia Whitley-Williams, division chief of allergy, immunology, and infectious disease in pediatrics at Rutgers Robert Wood Johnson Medical School, told WRCBtv. "It feels better to have your head up and it makes it easier to breathe," said Whitley-Williams.

If you're lying down, it becomes harder to cough, which could trap bad bacteria in your respiratory tract, and potentially even lead to pneumonia whether you've got the flu or even just a cold (via The New York Times). Staying vertical can also decrease the amount of mucus that drips down the back of your throat, which in turn can lessen coughing and sore throat symptoms, WRCBtv reported. Besides, it's easier to drink water and sip soup sitting up, which you should be doing frequently if you want to get better. 

Medicine just makes us feel better — even if it doesn't do anything (hello, placebo effect!). But when you're dealing with a cold or the flu, some medicines can hurt more than help. Let's get this out of the way first: You don't need antibiotics to treat the cold or flu, so don't pressure your doctor into prescribing them (it's a real thing, a study found). 

All variants of the common cold and the flu are viral infections, which won't respond to medicine designed to treat bacterial infections (via U.S. Food & Drug Administration). Besides, taking antibiotics when you don't need them can lead to unpleasant side effects, like yeast infections for people with vaginas, or antibiotic resistance, which can prevent the medicine from working in the future when your body is trying to fight off a bacterial infection. 

The Centers for Disease Control and Prevention says using pain relievers like acetaminophen or ibuprofen are okay — just use caution when giving them to children. But if you're seriously stuffed up, be wary of overusing decongestants. Linda Anagewa, a physician with PlushCare in Alea, Hawaii, told Real Simple that using over-the-counter nasal sprays to treat stuffy nose for more than a day or two can wind up leading to rebound congestion. No thank you!

Most people will get over a cold or the flu on their own in a week or two, according to the CDC. But if you experience symptoms like difficulty breathing or a fever that lasts longer than four days, it would be a mistake to avoid seeking medical care. As Advent Health explained, "If you feel sick, calling your doctor or scheduling a telemedicine visit can help your doctor determine the care you will need to monitor your condition and prevent it from developing into something more serious." 

According to the CDC, you should certainly call your doctor if you're not urinating, experiencing chest pressure or pain, or having dizzy spells or confusion. If you continue to get worse or temporarily get better and then worse, or experience severe muscle pains or weakness, you will want receive medical attention. Of course, this list of symptoms is not all inclusive. You know your body better than anyone else. If something is wrong, don't hesitate to seek medical care. But if you're simply dealing with a run-of-the-mill cold or uncomplicated flu, avoid the common no-nos to get well soon! Your body will thank you.
