Researchers have disclosed that just one sleepless night can disrupt the immune system. A study published in The Journal of Immunology revealed significant changes in immune cells after exposing young and healthy individuals to 24 hours of sleep deprivation. Scientists report that the immune system is extremely sensitive to sleep patterns, and even short-term sleep deprivation can lead to inflammation. It is emphasized that if these changes continue in the long term, the risk of developing chronic conditions such as diabetes, heart disease, and obesity may increase.

The study examined ‘monocytes,’ which are essential components of the immune system. Monocytes are cells that protect the body against external threats and are divided into three different types: Classical, intermediate, and non-classical monocytes. In particular, non-classical monocytes patrol the body to detect inflammation and regulate the immune response. Scientists explained that the sleep patterns and immune cell profiles of 237 healthy adults were examined in the research. The results showed that obese individuals had lower sleep quality and higher levels of inflammation in their bodies. Additionally, similar changes were observed in the immune system profiles of healthy individuals who were deprived of sleep for 24 hours.

Dr. Fatema Al-Rashed, who led the research, noted that sleep patterns are increasingly disrupted in modern society due to technological advancements, increased screen time, and changing social habits. Dr. Al-Rashed stated, “These disturbances in sleep patterns can have serious consequences on our immune system and overall health.” She expressed that their goal is to develop strategies that emphasize the importance of sleep health for public health, saying that measures such as guidelines for technology use and sleep-friendly practices in workplaces could be effective in preventing the spread of inflammation-based diseases.
