<p><b>Matt takes a deep dive into REM sleep this week, highlighting methods to enhance this vital stage for emotional regulation and creativity. Detailing pharmacological approaches, he focuses on the neurotransmitter acetylcholine and how medications like donepezil and modern DORAs can boost REM sleep, while also identifying common suppressors like alcohol and THC. Throughout the episode, he also emphasizes that the goal is not to maximize one stage but to achieve a balanced sleep architecture.</b></p><p><b>The discussion then covers behavioral and lifestyle strategies, explaining how simple changes like sleeping later into the morning, regular exercise, and stress management can remove natural roadblocks to REM. Matt also outlines how managing light exposure - by avoiding blue light at night and getting bright light in the morning - and consuming complex carbohydrates in the evening can further support this dream stage. Finally, the episode touches on emerging technologies like electrical brain stimulation that aim to amplify the brain's natural REM rhythms.</b></p><p><b>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.</b></p><p><b>One of this week's sponsors, </b><a href="https://drinklmnt.com/"><b>LMNT</b></a><b>, offers a science-based electrolyte drink with no sugar or artificial ingredients.
