Sleep Is The Mate Of Death

17 min • 2,183 words • 258 comments • 160 likes • podcast
Scott examines the relationship between sleep, synaptic homeostasis, and depression, exploring how sleep deprivation temporarily alleviates depression symptoms. Longer summary
Scott Alexander discusses a phenomenon where sleep deprivation temporarily alleviates depression, and explores the potential connection between sleep, synaptic homeostasis, and depression. He reviews the synaptic homeostasis hypothesis of sleep, which suggests that sleep helps renormalize synaptic connections, and connects this to research indicating that depression involves a deficit of synapses. The post then delves into various subtopics related to this theory, including the roles of REM and non-REM sleep, the effects of TMS and electroconvulsive therapy, and potential connections to circadian rhythms and bipolar disorder.

Melatonin: Much More Than You Wanted To Know

41 min • 5,247 words • 154 comments • podcast
Scott Alexander examines melatonin's effects, proper dosage, and uses for sleep disorders and circadian rhythm issues, emphasizing its dual role as a hypnotic and chronobiotic. Longer summary
Scott Alexander provides an in-depth analysis of melatonin, its effects, and proper usage. He explains that melatonin functions as both a hypnotic (inducing sleep) and a chronobiotic (shifting circadian rhythms). The post covers optimal dosing (0.3 mg, much lower than commonly available doses), use in treating circadian rhythm disorders, jet lag, and potential connections to other psychiatric conditions like seasonal affective disorder and depression. Scott also discusses personal experiences with melatonin, including its tendency to cause early waking and vivid dreams in some people. Shorter summary

Sleep

4 min • 508 words • 17 comments • podcast
Scott Alexander discusses his brain's arbitrary division of sleep into 'sleep mode' and 'nap mode', which interferes with establishing a normal sleep schedule, and asks for others' experiences and solutions. Longer summary
Scott Alexander describes a peculiar sleep pattern he experiences, where his brain distinguishes between 'sleep mode' and 'nap mode' based on the time he tries to fall asleep. Sleep attempts after 1 AM result in longer, groggier sleep periods, while attempts before 1 AM lead to shorter, more refreshing naps. This pattern interferes with his attempts to establish a normal sleep schedule and is incompatible with standard work hours. He shares his experiences with various sleep aids and techniques, noting their limited effectiveness in addressing this specific issue. Scott asks if others have experienced similar patterns and if they've found solutions. Shorter summary
