What You'll Learn
Sleep helps fight illness
When you're feeling under the weather, your body is telling you to slow down and rest. Sleep is an essential part of the recovery process, and getting enough of it can help your body fight off illness.
The urge to sleep when you're sick is your body's way of protecting itself. Illnesses often make people tired, and this fatigue is an adaptation called "sickness behaviour". It's your body's way of forcing you to slow down and rest, so you can get healthy. This tiredness is your body's way of promoting sleep to help recover from cellular stress.
Sleep is like medicine for the immune system. When you're asleep, your body can focus on keeping your immune system healthy and fighting off illness. This is because your body doesn't have the same demands on its resources as when you're awake. Your body can channel all its resources toward breaking a fever, fighting pathogens, and recovering from illness. Research shows that rats that slept while ill recovered faster than those that didn't.
When you're sick, your body may need more sleep than usual. Aim for more than nine hours if possible, as this is the amount recommended by the American Academy of Sleep Medicine and Sleep Research Society. While it can be challenging to get quality sleep when you're congested, achy, coughing, or shivering, there are some tips to help you get better sleep when you're sick. These include sleeping with your head propped up to help your nasal passages drain, avoiding cold medications that may keep you awake, and eating a few hours before bed so your body isn't hungry during the night.
So, if you're feeling sick, listen to your body and get some rest. Sleep is an important part of the recovery process, helping your body fight off illness and get back to full health.

Lack of sleep can make you sick
When sick, our bodies need rest. Sleep specialists share that quality sleep can help shorten the duration of an illness and boost the immune system's response to pathogens. When we are resting, our bodies can allocate more resources to fighting infection and recovering from cellular stress.
Research has shown that a lack of sleep can make you more susceptible to getting sick. Sleep is necessary to keep the central nervous system functioning properly, but chronic insomnia can disrupt how the body usually sends and processes information. Sleep deprivation can also negatively affect mental abilities and emotional states, causing irritability, mood changes, and compromised decision-making processes.
Additionally, a lack of sleep can lead to cognitive challenges, including thought processes related to learning, remembering, planning, and interpreting information. It can also cause memory and learning difficulties, emotional distress, increased production of stress hormones, and other mood changes. Sleep deprivation has also been linked to an increased risk of obesity, type 2 diabetes, hypertension, and some cancers.
Furthermore, when we are sick, our bodies may require more sleep than usual to support our immune systems in fighting infection. This is because our bodies produce protective, infection-fighting substances like antibodies and cytokines during sleep. A lack of sleep results in lower production of these substances, reducing the body's ability to combat foreign invaders such as bacteria and viruses.
Therefore, it is essential to prioritize sleep when sick to support the body's natural healing processes and boost the immune system's response to illness.

Resting is reducing activity
Resting is an important part of any fitness regimen, and it involves reducing physical activity to allow the body to recover. Rest days are necessary to help the body and mind recover from physical activity and prevent injury. They are also essential for muscle growth and repair, as well as maintaining mental health and preventing burnout.
When sick, resting becomes even more crucial. Illnesses often cause fatigue and lethargy, and getting adequate sleep is an essential part of the recovery process. Sleep boosts the immune system, helping the body fight off illness and recover faster. It is like medicine for the immune system, allowing it to replenish energy sources and focus on restoration.
The body's need for rest when sick is also supported by research. Studies have shown that adequate sleep can shorten the duration of an illness and improve the immune system's response. Additionally, rest helps to conserve the body's resources, allowing them to be directed towards fighting infection and recovery.
While resting when sick is important, it is also crucial to ensure proper nutrition and hydration. It is recommended to eat nourishing meals and stay hydrated by drinking enough water throughout the day.
In some cases, illness may persist or worsen despite adequate rest. If symptoms do not improve or if exhaustion and lethargy continue even after recovery, it is important to consult a doctor for further evaluation and treatment.

Sleep is like medicine
Research suggests that a lack of sleep can make you more susceptible to getting sick. When you're sick, your body may try to compensate by making you feel tired, which can help protect you from further illness. This is because staying inside and getting extra sleep helps your body build up its immune system.
Sleep is the only time of the day or night when restoration processes happen. It's when we replenish our energy sources, which are exhausted when we're sick. When we're doing activities, our body sends resources all over—to our muscles, our immune system, and our energy supply. When we're resting, more of these resources can be spent on recovery and fighting infection.
If you're sick, try to get a good long continuous stretch of sleep over the course of the night. This will help you hit all the stages of your sleep cycle, including restorative slow-wave sleep. If you're having trouble sleeping due to congestion, try sleeping with your head propped up to help your nasal passages drain and reduce pressure in your head.

T-cells are a type of white blood cell that plays a critical role in your body's immune response to infectious diseases.
