Sleep is a powerful tool when it comes to recovering from sickness. It is a natural way to boost your immune system and fight off illness. When you're awake, your body needs to direct energy to activities like thinking or moving around, but when you're asleep, that energy can be redirected to your immune system. This is because your body releases proteins called cytokines when you sleep, which communicate with cells in the immune system to help fight off infection. In addition, sleep gives your body time to repair itself, which is essential when you're sick.

What You'll Learn
Sleep boosts the immune system
Sleep is essential for the body to recover from illness. When you are sick, your body needs to replenish its energy sources, and sleep is the only time when this can happen. Sleep is like medicine for the immune system, giving your body time to repair itself and fight off illness.
During sleep, the body produces cytokines, a type of protein that targets infections. Cytokines are also involved in regulating sleep, with some promoting sleep to help the body fight off viruses. A 2019 study found that sleep helps T cells (a type of white blood cell) to more easily identify and destroy infected cells. Sleep also induces hormonal changes that help send T cells to the lymph nodes and stimulate an immune response against pathogens.
The immune system is closely linked to sleep, with immune signalling molecules present in the healthy brain, interacting with neurochemical systems to regulate normal sleep. When infection occurs, these interactions are amplified, causing changes in sleep architecture that support the generation of fever, which helps the body fight infection.
The importance of sleep for the immune system is further highlighted by the increased risk of certain diseases with sleep loss. Individuals who sleep less than 6 hours per night are more likely to develop diabetes and cardiovascular disease, demonstrating the wide-ranging consequences of sleep loss on physical health.
Therefore, when you are feeling unwell, listen to your body and get some rest. Sleep is your body's way of boosting its immune system to fight off illness and make a full recovery.

Sleep helps fight illness
Secondly, cytokines, which are a type of protein in your immune system that target infections, are produced and released during sleep. This means that sleep helps jump-start your immune response to your illness. Your body also has a better fever response while you are sleeping, which is another way it fights infection.
Thirdly, sleep can keep you away from other potential germs and diseases. When you are awake, your body needs to direct energy to activities like thinking or moving around. Therefore, getting rest allows your body to focus its energy on fighting off your illness.
Finally, sleep helps T cells (a type of white blood cell) more easily stick to infected cells and destroy them. Sleep loss is also associated with a higher risk of developing other health issues, such as diabetes, cardiovascular disease, and hypertension. Thus, getting enough sleep when you are sick is crucial for your overall health and well-being.

Sleep is restorative
When you're awake, your body needs to direct energy to activities like thinking or moving around. Sleep helps your body conserve energy, which can then be used to fight off infection. This is why you may feel sleepy when you're sick—it's your body's way of telling you it needs to rest so it can focus on getting better.
Sleep also helps your immune system do its job. Cytokines, a type of protein in your immune system that targets infections, are produced and released during sleep. This means that sleep helps jump-start your immune response to illness. Your body also has a better fever response when you're sleeping, which is another way it fights infection.
The link between sleep and the immune system is so strong that sleep loss has been associated with a higher risk of developing other health issues, such as diabetes, cardiovascular disease, and hypertension. Studies have also shown that those who get less than seven hours of sleep a night are three times as likely to develop the common cold compared to those who get eight hours or more.
So, if you're feeling under the weather, listen to your body and get some rest. It's one of the best things you can do to support your recovery.

Sleep prevents illness
When you are sick, your body produces cytokines, a type of protein that targets infections. Cytokines are produced and released during sleep, helping to jump-start your immune response to illness. Sleep also improves your body's fever response, which is another way it fights infection. Your immune system needs energy to function, and when you are awake, your body's energy is directed towards activities like thinking and moving around. Therefore, getting more sleep when you are sick helps give your body the energy it needs to fight the illness.
In addition, sleep helps to regulate immune signalling molecules, which interact with neurochemical systems to contribute to the regulation of normal sleep. These interactions are amplified during infection, indicating that they may play a role in the changes in sleep that occur during infection. For example, during infection, there is typically an increase in the amount of time spent in NREM sleep and a decrease in REM sleep. Sleep also impacts the cells the body uses to fight off viruses, with studies showing that sleep helps T cells (a type of white blood cell) more easily stick to infected cells and destroy them.
Furthermore, getting enough sleep can help prevent chronic illnesses such as diabetes, cardiovascular disease, and hypertension. Poor sleep can increase your susceptibility to certain types of illnesses, with studies showing that those who get less than seven hours of sleep per night are three times as likely to develop the common cold.
Therefore, getting enough sleep is crucial for preventing illness and supporting your immune system. When you are sick, listen to your body and get the rest you need to recover.

Sleep loss is detrimental to health
Sleep is an essential physiological process that allows the body and brain to rest, recover, and perform essential functions, including memory consolidation, emotional regulation, immune function, and general health maintenance. Sleep loss or deprivation can have detrimental effects on overall health and well-being.
Chronic sleep loss or deprivation can lead to poor short-term and long-term health outcomes and impair everyday functioning. It can negatively impact the immune system, making individuals more susceptible to infections and reducing their ability to fight off illnesses. Sleep deprivation has been linked to a higher risk of developing Type 2 diabetes, metabolic disorders, and cardiovascular issues such as high blood pressure and high cholesterol. It also negatively affects brain function, including learning and memory processes, and can increase pain sensitivity.
Additionally, sleep loss can contribute to mental health issues such as anxiety and depression. It can lead to changes in mood, increased stress and paranoia, and in severe cases, even psychosis. Sleep-deprived individuals may also experience impaired judgment, making them more prone to errors in decision-making. This can have far-reaching consequences, as evidenced by incidents like the space shuttle Challenger disaster, which was partially attributed to errors in judgment due to sleep loss.
The amount of sleep needed varies with age, with newborns requiring up to 17 hours and adults generally needing 7 to 9 hours of sleep per night. However, individual needs may differ, and some people may require more or less sleep to feel well-rested. Prioritizing sleep and maintaining consistent sleep and wake times are crucial for maintaining optimal health.
In summary, sleep loss is detrimental to health as it weakens the immune system, increases the risk of various health conditions, impairs brain function, and contributes to mental health issues. Adequate sleep is necessary for the body's restoration and recovery processes, and consistent sleep deprivation can have far-reaching consequences on overall health and daily functioning.

Frequently asked questions
Your body needs more energy to fight an infection, so it makes you feel tired so you sleep more and give it the rest it needs to recover.
Sleep helps to boost your immune system. When you're awake, your body needs to direct energy to activities like thinking or moving around. When you're asleep, your body can redirect that energy to your immune system so you can get better.
Make sure your sleeping environment is cool, dark, and quiet. Sleep with your head and neck slightly elevated if you have a stuffy nose to help ease congestion and promote mucus drainage. You could also try using a humidifier to soothe any irritation from a dry nose or throat.
