“The lack of sleep sets you up to potentially be more sick and makes it harder for your immune system to fight things off.” Sleep also has an impact on the cells the body uses to fight off viruses, which could impact how well you recover from a sickness.
Stay home and rest
Your body needs to battle what is ailing you. “Extra sleep can help your immune system function at its best and potentially shorten the duration of your illness,” says Heather Finn, MD, of Upstate Family and Preventive Medicine. “It can also help prevent you from becoming sick in the first place.”
When you're feeling your worst, staying in bed will likely be a no-brainer. As you work toward recovery, however, it's important that you avoid lying on your back, especially if you are experiencing shortness of breath.
As a general guide, mild to moderate physical activity is usually fine if you have a common cold. Symptoms of a common cold include a runny nose, nasal congestion, sneezing or minor sore throat. If you have a cold, you should consider reducing the intensity or length of your exercise.
Mild to moderate physical activity is usually OK if you have a common cold and no fever. Exercise may even help you feel better by opening your nasal passages and temporarily relieving nasal congestion.
When people are sick, they are not likely to wake up feeling particularly rested. One recommendation is to try to add 1 hour of sleep a night to usual sleep times, along with at least one, if not two, naps during the day.
Advise all employees to stay home if they are sick until at least 24 hours after their fever is gone without the use of fever-reducing medicines, or after symptoms have improved (at least 4-5 days after flu symptoms started).
Rest : This is the time to recharge your body's immune system. Rest and sleep are the best ways to do that. Make sure you're sleeping between eight to 10 hours at night. This is also a great chance to take a break from strenuous exercise for two to three days.
Let's clear the air on one thing – cold air doesn't make you sick. In fact, getting fresh air is good for you when you're feeling under the weather. When you're cooped up inside, you're sharing the same air with those around you.
As a minimum, people should stay away from work two to three days with a cold, and for the first week of influenza, recommends Dr Brooks. She says if you are sensing your body needs more rest, it's better to stay home.
Body temperature rises at night
For most people, body temperature naturally increases by 1.5°F at night. Combine that with your body's revved up immune system in the evening, and your low-grade fever is more likely to become a full-blown fever at night. This means more achiness and more of that all-around sick feeling.
Fever is part of the immune system's attempt to beat the bugs. It raises body temperature, which increases metabolism and results in more calories burned; for each degree of temperature rise, the energy demand increases further. So taking in calories becomes important.
At night, there is less cortisol in your blood. As a result, your white blood cells readily detect and fight infections in your body at this time, provoking the symptoms of the infection to surface, such as fever, congestion, chills, or sweating. Therefore, you feel sicker during the night.
You really do need extra sleep when you're not feeling well because of a cold or the flu, Taneja-Uppal says. That's especially true if you're running a low-grade fever, which can happen with colds, or the higher fever that accompanies the flu. Sleep helps your body fight the infection that's causing you to feel ill.
If symptoms get worse, rather than better, after 3-7 days, you may have acquired a bacterial infection. These symptoms can also be caused by a cold virus other than a rhinovirus.
Eating fruits and vegetables that are high in vitamin C is a smart move. Vitamin C boosts your immune system, which is how your body naturally fights off infection. If you're feeling nauseous, following the BRAT diet – bananas, rice, apples and toast – may be your preference.
Symptoms level off and fade: Cold symptoms usually last anywhere from 3 to 10 days. After 2 or 3 days of symptoms, the mucus discharged from your nose may change to a white, yellow, or green color. This is normal and does not mean you need an antibiotic.
Your body needs extra energy when it fights an infection. If you try to push through a cold, especially if you have a fever, you'll exhaust yourself. That could make your symptoms worse.
Yes, lack of sleep can affect your immune system. Studies show that people who don't get quality sleep or enough sleep are more likely to get sick after being exposed to a virus, such as a common cold virus. Lack of sleep can also affect how fast you recover if you do get sick.
During sickness, cells are under stress, and organisms experience sleepiness to promote sleep and recover from the cellular stress.
If your cold symptoms haven't cleared up after 10 days, but instead persist without improvement, your cold may have morphed into a sinus infection. Sinus infections happen when fluid builds up in the air-filled pockets in the face (sinuses), which allows germs to grow.
Taking a hot shower or a bath can really help to quell your various pains. The warmth from the bath can help soothe your lungs, and the steam will moisturize your throat and nasal passages that have been dried out from your sickness.
Experts suggest that particular positions can help or hinder sleep when you have a cold. When you sleep on your back, it can make congestion even worse. Try sleeping on your side, and prop up your pillows so you're sleeping at a slight angle to help prevent congestion from disrupting your sleep.
