New research reveals insight into the impact sleep quality has on a person's immune system, and how it could be linked to the development of diseases such as obesity, diabetes, and cardiovascular diseases.
The study found that even a single night of 24-hour sleep deprivation in young, lean, and healthy individuals altered the profile of immune cells that help regulate the immune system to resemble that of individuals with obesity—a condition known to drive chronic inflammation. This suggests that the immune system is highly sensitive to sleep and may adapt rapidly to changes in sleep pattern. According to the researchers, if these shifts persist, they could contribute to long-term inflammatory states and increase the risk of disease.
Substantial evidence exists linking sleep disorders and disturbances to an array of chronic conditions and morbidities, such as type 2 diabetes and cardiovascular diseases. It's also known that poor health outcomes can be driven by chronic inflammation but the direct influence of sleep on circulating immune cells, such as monocytes, is not as well understood.
Monocytes are a vital component of the innate immune system—the body's first line of defense that rapidly detects pathogens and kickstarts the immune response. There are three subsets of monocytes—classical, intermediate and non-classical monocytes. Non-classical monocytes patrol the body, sense and respond to inflammatory cues, and help to maintain and regulate the immune response.
In this study, the researchers analyzed the sleep patterns of 237 healthy adult participants of varying BMI, and took blood samples to profile the levels of different monocytes as well as markers of inflammation. They found that obese individuals had significantly lower sleep quality and higher chronic low-grade inflammation compared to the lean group. Non-classical monocytes were also increased significantly in obese participants, correlating with reduced sleep quality and elevated pro-inflammatory markers.

Even one overnighter compromised the immune system.
Sleep - the most signicant defense against a serious case of SARS-2-CoV (aka "COVID-19").
Almost never mentioned by all our medical and research "experts" with "expertise."
My cat and I sleep 10 hours every night.
Last night I only slept 8 hours, had to get up early for an appointment. Got home, fell asleep watching TV. woke up, made dinner and eating it at 8:45 p,m.
Kitty girl and I are apparently safe from inflammation. Cat scratch fever is a possibility.

“One night of lost sleep” huh?
Had plenty of nights of lost sleep and I’m still as healthy as ever.
Was going to say Nonsense, but you said it better.
I couldn’t sleep tonight - now this
As I’m reading this at 3:30 am EST…. 🤔
Ugh I was literally up all night because I have a (routine) surgery today and I’m all nervous. Stupid hernia!
I’m jealous. Usually 6 or 7 hours for me (and 3 cats). I’d love to get more for sure.
Hubby gets about 10 hours at night, and a long day during the day. I can’t nap. 😕
Tell it to my geriatric feline overlord.
I know, whenever I get poor sleep, I run out and get a covid booster the next morning. It really helps my immune system.
Seriously, I do not trust any medical research, studies or claims about anything anymore.
If one night of sleep deprivation can cause immune issues that then I’d be a walking bloated catastrophic fatal disease.
i love sleep, and I love coffee. Talk about a contradiction!
