Get a new mattress. Does your mattress make you toss and turn? Shmerling says. Regularly missing sleep contributes to obesity, which is also linked to inflammation.

Getting seven to nine hours of sleep per night is associated with reduced risks for many chronic diseases, including dementia. Brush your teeth regularly.

We're all supposed to brush our teeth twice per day, and floss them at least once per day. It's necessary to brush away the bacteria that can inflame the gums, lead to infection, and cause inflammation or infection elsewhere in the body. Inflammation in the gums also is strongly associated with diabetes," says Dr.

Tien Jiang, a prosthodontist in the Department of Oral Health Policy and Epidemiology at the Harvard School of Dental Medicine. Go for a walk. Aerobic exercise — the kind that gets your heart and lungs working, like brisk walking — is an important way to fight chronic inflammation.

Exercise may also increase the production of hormones that help keep inflammation in check," Dr. We all need at least minutes of aerobic activity per week to stay healthy.

If you've been inactive for a while, start with a five-minute daily walk and work your way up to 20 or 30 minutes a day.

Difficulty initiating or maintaining sleep, early awakening, interrupted or non-restorative sleep, and associated impairments in daytime functioning, which must be present for at least 3 nights per week and last for 3 months or longer.

A stage of sleep, also known as deep sleep, that ischaracterized by synchronized electroencephalogram activity with the presence of slow waves, or delta wave activity. SWS is often viewed as a time of rest for neocortical neurons, in which the brain recovers from activities during the day.

In animals and humans, the sleep—wake cycle, which influences physiological processes including immunity, as well as levels of behavioural arousal. A measure that tracks the electrical activity of the brain; one use is to graphically represent stages of sleep, which are defined by differences in waveform shape, frequency and amplitude.

A measure that tracks the electrical activity of muscle; one use, together with the EEG, is to define stages of sleep, such as rapid eye movement sleep, in which there is low muscle tone or activity accompanied by random and rapid eye movements.

Bursts of oscillatory electroencephalogram activity that occur during stage 2 sleep, caused by a peak of electrical activity in one area of the brain followed by a peak of electrical activity in an adjacent area of the brain. Large event waveforms of electroencephalogram activity that are considered to be a defining brainwave of stage 2 sleep.

They are characterized by a brief negative peak of electrical activity, followed by a longer-duration positive complex and then another negative peak. HPA axis. A neuroendocrine system that links the hypothalamus, pituitary and adrenal glands and functions to regulate the immune system in response to circadian signalling, behavioural states such as sleep and peripheral inflammatory signals.

A component of the autonomic nervous system that comprises nerve fibres that innervate lymphoid tissues, as well as nearly all other body tissues. The SNS regulates immune cell traffic and immune responses during sleep and in response to stress through the release of noradrenaline.

Also known as the circadian clock. Cycles of oscillation are determined by biochemical signals and synchronized by solar time to influence hour circadian timing in animals and in humans.

Imposing a loss of sleep during the night, for either part of the night in other words, partial night sleep deprivation or for the entire night in other words, total night sleep deprivation.

REM sleep. A stage of sleep, also known as paradoxical sleep, that is characterized by desynchronized electroencephalogram activity in a manner similar to waking, accompanied by random and rapid movement of the eyes together with low muscle tone.

REM sleep is viewed as the sleep period in which there is a propensity to dream. The ability of IL-6 to form an agonistic complex with a soluble IL-6 receptor and thereby to activate cells that lack the membrane-bound IL-6 receptor, such as neural cells.

A sleep-like state described in invertebrate models, in which a period of behavioural quiescence follows exposure to conditions that induce cellular stress, including exposure to tissue damage or extremes of temperature.

The amount of time spent asleep during the night, measured either by subjective report or objectively, using polysomnography or actigraphy. Short sleep duration is defined as less than the reference amount of 7 hours per night and is typically characterized as being less than 6 hours of sleep per night.

Long sleep duration is typically characterized as being more than 8 hours of sleep per night. The relative distribution of uninterrupted sleep, as opposed to wakefulness, during the night, as measured by sleep efficiency time spent asleep as a percentage of the total time spent in bed and wake time after sleep onset the amount of time spent awake after turning off the lights and initiating sleep.

An acute phase protein that is synthesized by the liver in response to the production of IL-6 by macrophages or T cells. Neuroendocrine hormones that belong to the steroid hormone class, which suppress inflammation and antiviral immune responses, in addition to having a role in the metabolism of protein, fat and glucose.

A state of decreased sensitivity to the anti-inflammatory effects of glucocorticoids, which can be caused by ongoing increases in inflammation as well as by a genetic predisposition. A component of the autonomic nervous system that comprises nerve fibres that innervate visceral tissues to regulate actions of the body when it is at rest, mainly through release of the neurotransmitter acetylcholine.

The state of a cell in which it is no longer able to replicate, which is also characterized by increased release of inflammatory mediators. An estimate of biological age given by evaluating changes in DNA methylation at particular genomic locations, which is found to be more predictive of mortality risk than is chronological age.

A sleep pattern characterized by high levels of sleep efficiency and low levels of awakening or sleep interruption. Reprints and permissions. Sleep and inflammation: partners in sickness and in health.

How to Protect Yourself There are several common-sense things you can do to protect yourself against inflammation: Get some sleep. You should try to get seven to nine hours of sleep a night.

Sleeping less can trigger your body to become inflamed.

A healthy diet, exercising regularly, getting enough sleep, maintaining good oral health, and reducing stress all reduce inflammation. If those strategies seem too big to take on all at once, just start with small steps in their direction, such as the following.

Eat fatty fish twice a week. Here's that salmon dinner we mentioned earlier. Salmon and other fatty fish such as anchovies, halibut, sardines, and tuna contain omega-3 fatty acids that reduce inflammation.

They may even help lower the risks for stroke and for the type of brain inflammation associated with Alzheimer's disease," says Dr. We need to get them from food.

Get a new mattress. Does your mattress make you toss and turn? Shmerling says. Regularly missing sleep contributes to obesity, which is also linked to inflammation. Getting seven to nine hours of sleep per night is associated with reduced risks for many chronic diseases, including dementia.

Brush your teeth regularly. We're all supposed to brush our teeth twice per day, and floss them at least once per day. It's necessary to brush away the bacteria that can inflame the gums, lead to infection, and cause inflammation or infection elsewhere in the body. Inflammation in the gums also is strongly associated with diabetes," says Dr.

Tien Jiang, a prosthodontist in the Department of Oral Health Policy and Epidemiology at the Harvard School of Dental Medicine. Go for a walk. Aerobic exercise — the kind that gets your heart and lungs working, like brisk walking — is an important way to fight chronic inflammation.

Exercise may also increase the production of hormones that help keep inflammation in check," Dr. We all need at least minutes of aerobic activity per week to stay healthy. If you've been inactive for a while, start with a five-minute daily walk and work your way up to 20 or 30 minutes a day.

There is a clear connection between sleep and inflammation, so if you suffer from any disorder or injury that has caused an inflammation, you will struggle to sleep at night.

The inflammation, which can cause you a lot of pain and discomfort, is removing the harmful pathogens from your body. A rapid inflammation, in response to a broken bone, or a viral infection, can cause swelling for a few days and dissipate quickly.

Arthritic pain, for example, can make it difficult to fall asleep, and you may wake up in the middle of the night in pain. Inflammation can even affect the sleep centers in your brain, and chronic inflammation from fibromyalgia can affect the functioning of your hypothalamus, making it very difficult for you to sleep at night.

Another way inflammation affects sleep is through your sleep cycles. Those with inflammation tend to spend less time in REM sleep, and suffer from a lack of deep sleep.

This in turn makes it harder to fall asleep the next night, and you may struggle with insomnia. If you have a chronic inflammation, consult your doctor as soon as possible to treat the cause of your inflammation. You may be able to take medication to reduce your inflammation, and manage pain.

Next, examine your sleep habits and sleep hygiene to improve your sleep. To sleep better, help your body develop a consistent sleeping pattern by going to bed and getting up at the same time each night.

This will train your body to feel sleepy at the same time each night, and wake up at the same time every morning. Remove the TV from your room and leave your phone outside.

Lower the temperature in the room for the most comfortable sleeping, and put up darkening blinds to make your room cozy for the night.

But they all represent healthy lifestyle habits that help fight chronic inflammation, a persistent state of the immune system that's linked to many health problems.

And the more healthy habits you practice, even simple ones, the better chance you'll have at thwarting chronic inflammation and disease. Normally, inflammation is part of how the body responds to threats such as injury or invading microbes.

The body sends special cells to attack and isolate invaders, clean up debris, and heal tissue and organs. It's an important system that kicks into high gear when we need it, and returns to normal when health is restored.

But sometimes the immune response continues indefinitely, fueled by unhealthy lifestyle habits. A constantly active immune system does more harm than good. It damages tissues and organs, and increases the risks for asthma, rheumatoid arthritis, inflammatory bowel disease, diabetes, heart disease, dementia, weight gain, heart attacks, and strokes.

Fortunately, for reasons we don't fully understand, certain healthy habits can counter chronic inflammation. A healthy diet, exercising regularly, getting enough sleep, maintaining good oral health, and reducing stress all reduce inflammation. If those strategies seem too big to take on all at once, just start with small steps in their direction, such as the following.

Eat fatty fish twice a week. Here's that salmon dinner we mentioned earlier. Salmon and other fatty fish such as anchovies, halibut, sardines, and tuna contain omega-3 fatty acids that reduce inflammation.

They may even help lower the risks for stroke and for the type of brain inflammation associated with Alzheimer's disease," says Dr. We need to get them from food. Get a new mattress.

Does your mattress make you toss and turn? Shmerling says. Regularly missing sleep contributes to obesity, which is also linked to inflammation.

Getting seven to nine hours of sleep per night is associated with reduced risks for many chronic diseases, including dementia.

Brush your teeth regularly. Those daily sleep-wake cycles we move through without much thought? Our circadian rhythms are working behind the scenes to keep us on schedule. When circadian rhythms are out of sync, so is sleep. Circadian rhythms also regulate our immune system , and with it, our levels of inflammation.

When circadian rhythms are disrupted, so is normal immune function. One way to help keep circadian rhythms in sync is to maintain a consistent sleep routine. Our bio rhythms thrive on consistency. Going to bed at the same time and waking at the same time every day reinforces the healthy circadian rhythms that govern both our sleep and our immune function, including inflammation.

Scientists still have a lot to learn about the specifics of the relationship between sleep and inflammation. Laboratory studies have tested acute, prolonged sleep deprivation—conditions under which sleep is restricted for 24 hours or more—and found this severe degree of sleep loss increases inflammation activity in the body.

Scientists have also studied partial sleep deprivation, the kind of chronic, insufficient sleep that so many people experience in their daily lives. While the study results are mixed, many studies show this form of everyday sleep loss also elevates inflammation.

It might surprise you to learn that sleeping too much can also trigger unhealthful inflammation. A study reviewed more than 70 scientific investigations into the relationship between inflammation and sleep.

The long-term effects of poor sleep on health are a major public health concern. The influence sleep can have on inflammation is a significant factor in managing health and guarding against disease over the course of our lives.

According to research, it takes as little as a single night. Research has shown that one night of insufficient sleep is enough to activate pro-inflammatory processes in the body. A study found that one single night of partial sleep resulted in significantly higher levels of NF-kB , a protein complex that acts as a powerful signal to stimulate inflammation throughout the body.

One noteworthy aspect of this study: the researchers found the higher inflammatory response occurred in female subjects, but not in male subjects. The differences in the ways women and men respond to sleep loss are important, and under-studied. This is an area of study that needs more attention.

But every night of sleep counts. Stress is a common obstacle to sleep. Worried, on high alert, agitated and anxious—these emotional and physical states of stress make it difficult to fall asleep and to sleep soundly throughout a full night. In turn, not getting enough sleep makes us more vulnerable to the physical and emotional effects of stress.

Many people fall into a difficult cycle: ending the day stressed out, having a hard time sleeping, feeling exhausted and even more stressed the next day—which leads to more problems sleeping.

This chronic sleep-stress cycle does more than make us tired and irritable. Stress is also a trigger for inflammation. Over time, chronic stress creates systemic, low-grade inflammation that wears at the health of our cells and makes us more vulnerable to disease.

Science is now identifying just what that means, and how stress contributes to disease by stimulating inflammation. A study identified the critical connections between chronic stress, increased inflammation, and the development of a range of diseases including cancer, heart disease, diabetes, and depression.

Sleep has a powerful, dual role to play in this complex interaction with stress and inflammation. Sleeping well can work directly to keep inflammation in check by avoiding the pro-inflammatory activity that occurs in the presence of poor, dysregulated sleep.

And sleep offers us significant protection against stress, itself a major contributor to chronic inflammation—a now known pathway to disease. One of the most exciting areas of sleep and health research involves the human microbiome. Our microbiome is the vast, dynamic, ever-shifting collection of bacteria and other micro-organisms that live within our bodies.

An unhealthy gut contributes to chronic inflammation. How does a gut become unhealthy? Poor diet, stress, medication and illness are all contributors. So, too are disrupted circadian rhythms and poor sleep. Poor and insufficient sleep appear to change the composition of our natural microbiota, decreasing beneficial bacteria and increasing bacteria associated with disease.

The emerging science points to a powerful two-way street between sleep and gut health. Sleeping well is one way to help maintain a healthy gut. Both those pillars—healthy sleep and a balanced, thriving gut—can work to limit harmful inflammation, and may help deliver long-term protection against disease.

Sleep well can be a potent tool in helping guard against this often silent, and damaging, form of inflammation. Michael Breus, Ph.
