Bryan Johnson explains how a single night of poor sleep raises brain-injury markers by 20%, matching levels seen after a concussion. The protein S100B leaks into your bloodstream and can kill neurons. He calls bedtime your most important appointment of the day.
Sleep deprivation is literally brain damage. A study in young participants showed that one night of bad sleep increased levels of this protein, called S100B, by 20%, the same level as caused by a traumatic brain injury. Now what happens is it enters the bloodstream, it leads to toxicity, which can lead to neuronal death. So how do we stop this from happening? Get high quality sleep. You are a professional sleeper. Bedtime is the most important appointment of the day. Be on time and respect yourself.
