Dr. Eti Ben Simone is back with Matt Walker to delve into a range of intriguing topics surrounding sleep, circadian rhythms, and the impact of shift work on our health, all within the engaging context of today’s installment of their increasingly popular Ask Me Anything (AMA) sessions. Their conversation begins by exploring the intriguing link between the APOEε4 genotype and sleep disturbances, particularly concerning Alzheimer's disease. It's noteworthy that individuals carrying the APOEε4 variant, especially those with two copies, face a heightened risk of developing Alzheimer's. Surprisingly, research shows that these individuals tend to experience more deep non-REM sleep, typically associated with better memory. This paradoxical discovery hints at the possibility that sleep may serve as a compensatory mechanism to counteract the memory decline associated with APOEε4.The discussion then shifts to the consequences of shift work on our health, a topic of great interest among the podcast's audience. Shift work disrupts our circadian rhythm, the internal clock governing various facets of our health, including our sleep patterns. Quick transitions between different shifts, akin to frequent experiences of jet lag, can prove particularly detrimental. Such rapid shift rotations contribute to increased rates of insomnia and diminished sleep quality, with some night shift workers reporting sleep disturbances nearing 40%. The disruption of the circadian rhythm impacts not only our sleep but also a multitude of physiological functions. This underscores the paramount importance of maintaining a consistent sleep schedule for our overall well-being.Please note that Matt is not a medical doctor, and none of the content in this podcast should be considered medical advice in any way, shape, or form, nor prescriptive in any way.One of the podcast’s new sponsors is Levels, the groundbreaking continuous glucose monitor that keeps track of your blood sugar levels day and night.
