Kimberly Truong. Over the past few decades, sleep science has developed immensely, revealing the far-reaching importance of sleep for virtually every Lack of sleep side effects stomach of the body. As research has delved further into the links between sleep and physical healthit has become increasingly clear that sleep and the immune system are closely connected. The immune system is critical to overall health. It is fundamental to healing wounds, warding off infections, and protecting against chronic and life-threatening illnesses.
Sleep and the immune system have a bidirectional relationship. Immune response, like that caused by a viral infection, can affect sleep. At the same time, consistent sleep strengthens the immune system, allowing for balanced and effective immune function. Lack of sleep, on the other hand, can throw off the immune system.
Evidence indicates that in both the short- and long-term, sleep deprivation can make you sick. The immune system is a complex network throughout the body that provides multiple lines of defense against illness. These defenses are generally divided into two main : innate immunity and adaptive immunity. Innate immunity is a broad type of protection with several layers of defense.
Adaptive immunity, also known as acquired immunity, includes defenses that you develop over time and that are targeted to specific threats. Numerous components contribute to the complexity of the immune system. An important component of our immune system are leukocytes or white blood cells. Our immune system reacts to pathogens in an immediate innate and learned adaptive way, which allows us to safely interact with our environment every day. When a white blood cell detects a foreign pathogen, it releases cytokines to tell other white blood cells to prepare to attack.
Cytokines are proteins that act as messengers for the immune system. Other chemicals, such as histamine, are also involved in immune reactions like swelling or redness. When functioning optimally, the immune system maintains a delicate balance.
Sleep provides essential support to the immune system. Getting sufficient hours of high-quality sleep enables a well-balanced immune defense that features strong innate and adaptive immunity, efficient response to vaccines, and less severe allergic reactions. In contrast, serious sleeping problems, including sleep disorders like insomniasleep apnea, and circadian rhythm disruption, can interfere with the healthy functioning of the immune system.
Sleep is an important period of bodily rest, and studies indicate that sleep plays a crucial role in the robustness of our immune system. In fact, sleep contributes to both innate and adaptive immunity. Researchers have found that during nightly sleep, certain components of the immune system rev up. For example, there is an increased production of cytokines associated with inflammation. When someone is ill or injured, this inflammatory response may help with recovery, fortifying innate and adaptive immunity as the body works to repair wounds or fight off an infection.
Analysis of the type of cells and cytokines involved in this nighttime immune activity indicates that its role is to strengthen adaptive immunity.
Just like sleep can help the brain consolidate learning and memoryresearch suggests that sleep strengthens immune memory. While this immune system activity during sleep is beneficial, a critical aspect of this process is that it is self-regulating.
In this way, getting enough high-quality sleep facilitates the delicate balance of immune function that is vital for both innate and adaptive immunity. Vaccines work by introducing a weakened or deactivated antigen to the body, triggering an immune response. In this way, immunizations effectively teach the immune system to recognize and attack that antigen. Sleep is an important factor that helps determine the effectiveness of vaccines. While those studies involved total sleep deprivation after vaccination, other studies have found reduced vaccine effectiveness in adults who habitually fail to get at least seven hours of sleep.
People who get insufficient sleep may not give their bodies enough time to develop immunological memory, potentially leaving them unprotected despite having been vaccinated. Allergies occur when the immune system overreacts to something that does not cause harm to most people, and growing evidence connects sleep and allergies. When the circadian rhythm is disrupted, it may increase the likelihood and severity of allergic reactions.
Lack of sleep has been tied to allergies as well. Sleep deprivation has wide-ranging health effects, and mounting evidence indicates that it can disrupt the immune system and make it easier for you to get sick. A lack of nightly sleep has been connected to both short-term illnesses and the risk of chronic diseases like diabetes and heart problems. Researchers increasingly believe that this is tied to how sleep deprivation interferes with the normal functioning of the immune system. In the short-term, the risk of infections has been found to be higher in people who sleep less than six or seven hours per night.
Studies have found that insufficient sleep makes it more likely to catch the common cold or the flu. In addition, people in intensive care units ICUs who have acute recovery needs may have their healing hampered by a lack of sleep. Lack of sleep has been connected to multiple long-term health problems, and this is believed to be related to the negative effects of sleep deprivation on the immune system. In people with healthy sleep, inflammation during the night recedes back to a normal level before waking up.
This low level of systemic inflammation takes a toll, contributing to an elevated risk of diabetes, cardiovascular disease, pain, and neurodegenerative diseases. Persistent Lack of sleep side effects stomach has been associated with depressionwhich may explain the high rates of this disorder among people with sleeping problems.
Inflammation has also been linked to cancer, which animal research suggests may be worsened by insufficient sleep. Instead, this low-grade inflammation can become chronic, further worsening long-term health. While sleep plays a critical role in immune function, the immune system also affects sleep in multiple ways. Infections can trigger various responses from the immune system, including a lack of energy and sleepiness. This is one of the reasons why people who are sick often spend more time in bed and sleeping. The nature of sleep changes during infection as well, altering how much time is spent in certain sleep stages.
Specifically, the immune response induces more time in stage 3 non-rapid eye movement NREM sleepwhich is also known as deep sleep. Deep sleep involves greater slowing of bodily processes, allowing the immune system to utilize more energy to fight infection.
Fever is another important immune response. Higher body temperature can trigger new waves of immune defense, and it also makes the body more hostile to many pathogens. According to this view, deep sleep N3 stage is increased when we are fighting Lack of sleep side effects stomach infection because it is the period of sleep when our metabolism is lowest, freeing up energy to mount a high fever response.
In addition, shivering is beneficial in releasing heat and maintaining a fever. Our body cannot shiver during REM sleep due to muscle atonia, and therefore during an active infection, REM sleep is virtually abolished. While researchers continue to study the relationships between sleep and the immune system, these effects demonstrate how closely interlinked they are and how the immune system can harness sleep to improve its ability to fight off infection. Given the importance of sleep for immune function, making it a priority to get a sufficient amount of uninterrupted sleep every night can work to strengthen your immune system.
Improving sleep often starts by focusing on your habits, routines, and sleeping environment. People with chronic or severe sleeping problems or issues with recurring illnesses should talk with a doctor. A doctor can work to identify an underlying cause and the best measures to address it. People with sleep disorders like insomnia may benefit from a treatment like cognitive behavioral therapy for insomnia CBT-I. This approach works to reduce negative thoughts about sleep and promotes healthy sleep and reduced s of inflammation. Relaxation techniques, including mind-body methods like yoga or tai chi, have also shown positive in improving sleep while enhancing immune system functionincluding boosting vaccine response and decreasing indicators of systemic inflammation.

Balanced Immune Response When functioning optimally, the immune system maintains a delicate balance. Sleep and Innate and Adaptive Immunity Sleep is an important period of bodily rest, and studies indicate that sleep plays a crucial role in the robustness of our immune system.
The inflammation that happens during sleep could harm physical and mental performance if it occurred during waking hours, so the body has evolved so that these processes unfold during nightly sleep. Melatonina sleep-promoting hormone that is produced at night, is adept at counteracting the stress that can come from inflammation during sleep.
