Ī link was found between higher CRP levels, chronic stress, and burnout in women with psoriasis. In a study that examined job stress and CRP levels among Chinese workers, effort, overcommitment, and effort-reward imbalance were all significantly correlated with higher CRP while rewards were significantly related to lower CRP. Scientists found that both psychological and social stress significantly impacts CRP. 3) StressĬRP is elevated in chronic stress and may be the link between stress and low-grade inflammation-related diseases. 2) SmokingĬigarette smoking increases CRP. Excessive, irregular, and insufficient sleep have all been linked with higher CRP levels and inflammation. Men and women with higher sleep-wake concordance had lower CRP values. whether couples are awake or asleep at the same time throughout the night. Interestingly, one study looked at sleep-wake concordance i.e. On the other hand, a recent investigation focusing on young adults who nap infrequently reported that IL-6, an inflammatory molecule that usually increases together with CRP, increased following sleep deprivation but decreased after subsequent naps. In one study, self-reported nappers had increased CRP, and the authors suggested that frequent naps may actively elevate CRP, possibly via enhanced blood pressure upon waking. The relationship between daytime naps and CRP is ambiguous. It’s quite possible that longer sleep time doesn’t cause higher CRP, but rather people with inflammation (and therefore higher CRP) need more sleep.Įlevated levels (>3.0mmol/l) of CRP were observed in both ≤6h and ≥10h sleep in a study of over 2.5k aging men. On the other hand, several investigations have linked oversleeping (≥9 hrs/night) with higher CRP in those with Obstructive Sleep Apnea and type 2 diabetes. Īnother study showed that CRP was elevated immediately after sleep restriction, and since this protein has a half-life of 19h, this elevation was sustained even after two days of recovery sleep. In one study, both total (88 hours) as well as partial (4.2 hours during 10 consecutive nights) sleep restriction significantly increased blood levels of CRP. Insufficient sleep has been linked to inflammation.įor example, scientists have found that CRP increases with both sleep deprivation and poor self-rated sleep quality in a dose-dependent manner. Excess sleep, insufficient sleep, frequent napping, and infrequent napping have all been linked with elevated CRP, but these relationships seem to depend on both night and daytime sleep patterns. There is an established, yet complex, relationship between CRP and sleep. Lifestyle Causes of High CRP 1) Sleep Disturbances If your CRP is high, work with your doctor to get an accurate diagnosis. Keep in mind that CRP can be elevated due to underlying medical conditions that need treatment. Keep reading to find out about the main lifestyle, dietary, hormonal, and other causes of high CRP that are rarely talked about.īelow are some of the causes that have been associated with higher CRP levels. A plus sign next to the number “” means that the information is found within the full scientific study rather than the abstract.ĬRP is a protein that links stress, emotional, and socioeconomic cues to chronic inflammation and heart disease. ![]() Note that each number in parentheses is a clickable link to peer-reviewed scientific studies.
