Sick Days: Why We Sleep More When Ill

Sleep is an essential part of the recovery process when you're sick. It helps boost your immune system, giving your body the time and energy it needs to heal. This is because sleep gives your body the opportunity to produce cytokines, a type of protein that targets infections. Getting enough sleep is also important in regulating your immune system, with a lack of sleep making you more susceptible to getting sick.

When you're sick, your body needs rest to recover, and sleeping is one way it tells you to slow down. This feeling of tiredness is an adaptation called sickness behaviour, forcing you to take it easy.

So, if you find yourself sleeping all day when you're sick, it's your body's way of helping you get better.

Sleep helps your body repair itself

Sleep is an essential part of recovery when you're feeling unwell. It helps your body repair itself and gives your immune system a boost.

When you're sick, your body needs rest. Sleep gives your body time to repair itself, and it's also when your immune system is best able to function. Sleep is like medicine for the immune system, helping you make a full recovery.

During sleep, your body releases proteins called cytokines, which communicate with cells in the immune system to help fight off infection. Cytokines also promote sleep, so giving in to feelings of fatigue helps your body make more cytokines and fast-track your recovery.

Sleep also impacts the cells your body uses to fight viruses. Research suggests that sleep helps T cells (a type of white blood cell) stick to infected cells and destroy them. Slow-wave sleep and the circadian rhythm induce hormonal changes that help send T cells to the lymph nodes and stimulate an immune response against pathogens.

Natural killer cells, another type of immune cell that attacks tumour cells and those invaded by viruses, are also dependent on sleep. Even modest amounts of sleep loss can cause their activity to drop significantly.

While the exact reasons we tend to sleep more when sick aren't fully understood, research suggests that it is evolutionarily conserved across species to rest when the body is stressed.

Sleep boosts your immune system

Secondly, certain immune processes and responses occur during sleep, which help your body fight off illness. Cytokines, a type of protein in your immune system that targets infections, are produced and released during sleep. Cytokines also promote sleep, so by sleeping more, your body can make more cytokines, and in turn, fight infection more effectively.

Additionally, your body has a better fever response while you're sleeping, which is another way it fights infection. Sleep also impacts the cells your body uses to fight viruses. Research suggests that sleep helps T cells, a type of white blood cell, to stick to infected cells and destroy them. Slow-wave sleep and the circadian rhythm induce hormonal changes that help send T cells to the lymph nodes and stimulate an immune response against pathogens.

Sleep is also important for responding to cellular stress, repairing damaged tissues, and regulating immune cell proliferation and trafficking. By sleeping, you are conserving energy, which is important as fevers induced during infection are metabolically demanding.

Therefore, it is clear that sleep plays a crucial role in boosting your immune system and helping your body fight off illness.

Sleep helps your body fight off illness

Sleep is an essential part of recovery when you're feeling unwell. While you sleep, your body is able to focus on fighting off illness and restoring your health.

When you're sick, your body releases proteins called cytokines, which are a type of protein in your immune system that targets infections. Cytokines are produced and released during sleep, helping to jump-start your immune response to illness. Some cytokines even promote sleep, so giving in to feelings of fatigue helps your body make more cytokines and fast-track your recovery.

Sleep also helps your body's fever response, which is another way it fights infection. 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, enabling you to get better faster.

Additionally, sleep impacts the cells your body uses to fight off viruses. Research suggests that sleep helps T cells, a type of white blood cell, more easily stick to infected cells and destroy them. Slow-wave sleep and the circadian rhythm induce hormonal changes that help send T cells to the lymph nodes and stimulate an immune response against pathogens.

Sleep is also important for responding to cellular stress, repairing damaged tissues, and regulating immune cell proliferation and trafficking. While the exact reasons we tend to sleep more when sick aren't fully understood, research suggests that resting when the body is stressed is evolutionarily conserved across species.

So, if you're feeling under the weather, listen to your body and get some extra sleep. It's one of the best things you can do to support your immune system and speed up your recovery.

Sleep is like medicine for your immune system

When you're asleep, your body is able to redirect energy to your immune system, allowing it to fight off illness. Cytokines, a type of protein in your immune system that targets infections, are produced and released during sleep. This means that sleep jump-starts your body's immune response to illness.

Sleep also improves your body's fever response, which is another way it fights infection. Getting enough sleep ensures your body can produce cytokines productively. Research has shown that a lack of sleep may increase your susceptibility to getting sick and can even impact your risk factors for autoimmune issues and cancer.

When you're sick, your body needs more sleep than usual to help it recover. While there is no set amount, it's recommended that you aim for more than nine hours of sleep per night. Napping throughout the day can also help boost your overall sleep and aid your recovery.

To improve your sleep when you're sick, try to avoid screens and eat a light meal a few hours before bedtime. Staying hydrated is also important, but try to cut down on liquids about an hour before bed to reduce the need for nighttime bathroom trips. Using a humidifier can also help ease respiratory symptoms and improve your sleep.

Sleep helps your body conserve energy

When you're feeling under the weather, your body is telling you to slow down and rest. Sleep is an essential part of recovery and helps your immune system fight off illness.

During sleep, your body releases proteins called cytokines, which are a type of protein in your immune system that targets infections. Cytokines are produced and released during sleep, helping to jump-start your immune response to illness. Some cytokines even promote sleep, creating a positive feedback loop that aids in recovery.

Additionally, sleep impacts the cells your body uses to fight off viruses. Research suggests that sleep helps T cells, a type of white blood cell, more easily stick to and destroy infected cells. Slow-wave sleep and the circadian rhythm induce hormonal changes that help send T cells to the lymph nodes, further stimulating an immune response.

Fevers induced during infections are also metabolically demanding, and sleep helps the body conserve energy to break these fevers. Sleep is important for responding to cellular stress and repairing damaged tissues, which requires energy that your body can conserve by sleeping.

By sleeping more when you're sick, you're giving your body the rest it needs to direct its energy towards recovery, allowing you to heal and get back to full health more quickly.
