The Secret To A Good Nights Sleep with Stephanie Romiszewski | E64

KEYPOINTS

• 01

  Doctors receive almost no formal sleep training even though sleep occupies roughly a third of life.

  Stephanie Romiszewski, a sleep physiologist whose training pathway includes work connected to NASA and Harvard Medical School sleep science, argues the medical system leaves insomnia under-taught. Patients spend decades asking GPs for help, yet undergraduate curricula she has examined devote minimal hours to the physiology of sleep. Into that gap rush books, gadgets, and Instagram rules that sound scientific but often worsen anxiety about sleeping.

• 02

  The belief you must land exactly seven or eight hours every single night is her patients' #1 misconception.

  When she crowdsourced questions before the podcast, the median ask was whether nightly totals must be perfect. She answers with 'perfection is the enemy of the good': bodies prefer consistency across weeks more than identical nights. Six-and-a-half hours followed by seven-and-a-half can be fine if most nights—roughly 80%—offer enough opportunity. Obsessing over an exact number creates performance pressure that itself fragments sleep.

• 03

  CBT for insomnia (CBT-I) rebuilds sleep drive and bed–sleep association over weeks, not overnight.

  She stresses CBT-I is not the same protocol as CBT for depression or anxiety. It systematically retrains when you go to bed, how long you stay if awake, and how to accumulate enough sleep pressure. People arriving hungry for a tonight-only hack will be disappointed; a trick that works once rarely survives. Her short-term message is reassurance: one bad night will not destroy you while you invest a few weeks in retraining.

• 04

  Habitual snoozing signals a deeper timing or debt problem, and research shows little restorative benefit.

  If the snooze button is part of every morning, question upstream sleep opportunity and wake scheduling. Restoration requires sufficient time in deeper stages; typical snooze slices of several minutes do not deliver that physiology. Better to set one honest alarm and fix the schedule than to fragment the final sleep cycle.

• 05

  Every cell runs clocks that crave regulation—moving wake and sleep goalposts confuses melatonin timing.

  Light exposure, meal timing, work, exercise, and social contact all tell the brain when to prepare for night. Pandemic routine collapse removed those anchors: more people woke buzzing at 3 a.m., stared at nothing or a million thoughts, and reported graphic dream recall. Ironically, busy structured lives are often easier to treat than idle unstructured ones because routine is medicine.

• 06

  Textbook 'perfect sleep hygiene' does not describe how good sleepers actually live.

  Endless commandments—never caffeine, never alcohol, always a bath, buy this pillow—fail the reality test. Plenty of solid sleepers break rules yet sleep well because their circadian and sleep-drive systems are intact. Environment matters, but she refuses to dictate one bed or fad product; hyper-control can become the insomnia.

• 07

  Caffeine as an upper paired with pills or supplements as a downer cannot reset sleep long-term.

  Short-term use of sleeping pills or caffeine can be pragmatic. Chronic use brings tolerance, side effects, and false hope of a miraculous reset. Chemicals do not replace behavioral retraining of the sleep system, and escalating doses often deepen the sense that nothing works.

• 08

  Sleep and mental health form a bidirectional loop—waiting to prove which came first wastes time.

  Poor sleep worsens mood regulation; anxiety and depression fragment sleep. Clinically she wants both sides addressed. Medical dismissiveness toward insomnia leaves people lonely and hopeless when expectations of a magic pill fail.

• 09

  Find your personal sleep need via holiday baselines or clinical sleep-restriction titration—not influencer charts.

  After three or four recovery days on holiday, notice what duration appears naturally. In therapy, sleep restriction raises efficiency until adding more time in bed stops helping—revealing today's set point, including rare genetically short sleepers who thrive on less.

• 10

  Insomnia often shows up as learned wake-ups: the brain rehearses middle-of-night alertness until it becomes habit.

  When nights of waking repeat, conditioning sets in. Resolving that habit requires changing the response to nocturnal wake—not only buying darker curtains. Education plus CBT-I targets the conditioned arousal that DIY tips miss.
