Can hsCRP help with sleep?

hsCRP (high-sensitivity C-reactive protein) is a well-established marker of systemic inflammation. Observational studies suggest that chronically elevated hsCRP levels are associated with poorer sleep quality, sleep disturbances, and increased daytime sleepiness – likely via inflammatory pathways that modulate sleep-wake regulation. However, the evidence is predominantly mechanistic and not causal. hsCRP is not a direct sleep aid or diagnostic tool for sleep disorders. An elevated level may indicate underlying inflammation that impairs sleep – for example in obesity, metabolic syndrome, or chronic stress. Conversely, sleep deprivation can raise hsCRP. For individual sleep optimization, hsCRP alone is insufficient; persistent sleep issues warrant medical evaluation. Caveat: MyBody-X offers hsCRP in its blood test panel, but interpretation must be in clinical context. Evidence: mechanistic/unclear.
