CHAPTERS
- 0:00 – 4:03
Ashley Mason's path to CBT-I and why insomnia is so common
After a short preview of themes from the episode, Peter Attia welcomes Ashley Mason and asks how she came to insomnia. She describes training near one of CBT-I's co-inventors, how CBT-I works like a recipe, and the reward of watching patients get their lives back.
- •Mason studied at the University of Arizona alongside Dick Bootzin, a co-inventor of CBT-I
- •CBT-I is more predictable than many other psychotherapies
- •She runs her CBT-I clinic at night on top of her regular job because it is so rewarding
- •Patients often say they have their lives back by the seventh session
- 4:03 – 11:41
Defining insomnia: diagnosis, prevalence, and how it persists
Mason explains that insomnia is a clinical diagnosis requiring months of distressing sleep problems, and that point prevalence is roughly 5 to 10% of adults. She lays out predisposing, precipitating and perpetuating factors, and says CBT-I targets the behaviors that perpetuate the problem rather than the original cause.
- •No blood test or one night in a sleep lab diagnoses insomnia; about three months of distressing symptoms is the rough threshold
- •Roughly 90% of adults will struggle with insomnia at some point, and 5-10% have it at any given time
- •Precipitating events end, but the coping behaviors (naps, Ambien, phones in bed) persist
- •Mason does not ask about the cause until the end of the first session because the intervention is the same
- 11:41 – 21:17
Racing minds, middle-of-night waking, and low-hanging fruit
Peter asks whether trouble falling asleep differs from waking at 1 a.m. Mason says both need the same treatment and describes scheduled worry time, fluid timing for nighttime urination, cotton blankets instead of down comforters, and warming the hands and feet.
- •Scheduled worry time moves worry into a set period, uncluttering the day and the pillow
- •Limiting fluids with dinner plus an electrolyte tab helped some men cut nighttime urination from three times to once
- •Circadian temperature rhythm means trapping heat with down comforters can disrupt sleep
- •Warm hands and feet help the body dump core heat to fall asleep
- •CBT-I aligns time in bed with when the body can actually produce sleep
- 21:17 – 33:00
What CBT is and the history and components of CBT-I
At Peter's request, Mason explains CBT through the thoughts-feelings-behavior triangle. She traces CBT-I back to the 1970s and the Bootzin stimulus control method, then outlines its pillars: stimulus control, time in bed restriction, cognitive restructuring, and relaxation.
- •CBT intervenes on connections between thoughts, feelings, and behaviors
- •Stimulus control grew from a library-carrel study skills experiment and means the bed is only for sleep and sex
- •Time in bed restriction matches time in bed to the sleep the body can produce
- •Thought records weigh evidence for and against a thought to build a balanced one
- •Dismantling studies show removing stimulus control or time in bed restriction stops the treatment working
- 33:00 – 42:29
Implementing time in bed restriction, wake times, and napping
Mason contrasts classic CBT-I with her own clinic's approach: a seven-day sleep diary, sleep time plus 30 minutes, a 5.5-hour floor, and her own method of assigning a realistic wake time. She skips restriction in week one, removes naps, and explains the 85% sleep efficiency benchmark and 15-minute bedtime adjustments.
- •Classic CBT-I uses a sleep diary to calculate average sleep and adds 30 minutes to set time in bed
- •Mason picks a realistic wake time from the diary and gives a week at that wake time before any bedtime
- •One or two of every eight patients improve just from a consistent wake time
- •Naps are removed first, with a 25-minute alarmed nap opportunity only for some very old patients
- •If sleep efficiency exceeds 85%, bedtime moves back 15 minutes a week
- 42:29 – 49:50
Naps on trips, couch dozing, couples, and chronotypes
Peter asks about his hunting-trip naps, falling asleep on the couch, and mismatched partner schedules. Mason says napping on a trip is not insomnia, suggests scheduling couch time together, and explains deep sleep early in the night and the evolutionary diversity of night owls and larks.
- •Napping while sick is fine, but in bed rather than on the couch
- •Falling asleep on the couch can mean the body is ready for bed, and noise may degrade sleep quality
- •Couples can schedule time together at hours when the sleepier partner is awake
- •Deep sleep dominates early in the night and REM later
- •Being a night owl or lark is not pathologic and is hard to change
- 49:50 – 58:54
Sleep hygiene: temperature, light, and mattress cooling
Peter returns to sleep hygiene, starting with room temperature and darkness. Mason endorses mid-60s rooms, socks and cotton bedding, and eye masks or blacked-out lights, and discusses her concerns about mattress devices, night shift work, and circadian temperature disruption.
- •A mid-60s room works well; cold feet can be handled with socks or a small auto-shutoff heating pad
- •Light through closed eyelids can drive early morning awakenings, so eye masks or covering lights help
- •Mason is wary of mattress devices that can heat or cycle temperature, citing the circadian temperature rhythm
- •Peter pushed back on whether night shift work is causally linked to cancer
- •Hotels and hot mattresses are common problems; a cool room is the simplest fix
- 58:54 – 1:05:03
Blue light versus stimulation, and A-B testing your habits
Peter proposes that stimulating content, not blue light, is the main problem before bed, and Mason largely agrees. She notes some patients with sleep-onset insomnia benefited from orange wraparound glasses, and recommends testing single changes over two weeks with a paper sleep diary.
- •Social media, work, and email are more disruptive than blue light itself
- •Passive TV is less disruptive than interactive email for Peter
- •A few patients stopped Ambien after wearing orange wraparound glasses two hours before bed
- •Test one change at a time for two weeks using a paper sleep diary
- 1:05:03 – 1:10:25
More simple fixes: medication timing, decaf, and caffeine cutoff
Mason lists further low-hanging fruit: taking medications at consistent, appropriate times, recognizing that decaf contains caffeine, and moving all coffee before 11 a.m. without reducing the amount. She explains caffeine's half-life and why people who say it doesn't affect them may still be affected, and advises against falling asleep to podcasts.
- •All medications have circadian effects, so timing and consistency matter
- •Decaf coffee can contain meaningful caffeine
- •Her standard is caffeine done by 11 a.m., but she never reduces intake to avoid withdrawal
- •Caffeine's half-life of four to six hours means afternoon coffee lingers
- •She advises against falling asleep to podcasts
- 1:10:25 – 1:16:11
Mindfulness, CBT-I effectiveness, trackers, and why it fails
Peter asks about mindfulness, and Mason says progressive muscle relaxation is the tested component while mindfulness adds satisfaction but not better sleep outcomes. She cites remission and improvement rates, says treatment fails when people don't do it, and explains why she tells insomnia patients to take off sleep trackers.
- •Mindfulness added to CBT-I did not improve sleep metrics, though people liked it
- •About 50% reach remission and 70% see meaningful improvement
- •Treatment fails when people don't adhere, and genetically short sleepers distressed about sleep won't be helped
- •She tells patients with insomnia to take off their trackers
- •Four or more sessions work better than one or two
- 1:16:11 – 1:26:22
Access to CBT-I, apps and AI, and handling nighttime awakenings
Mason explains the long waits for CBT-I, insurance barriers, and the provider directory, then discusses whether apps or AI could scale it. She also describes what to do when awake at night: get out of bed, do a mildly boring activity, and reset.
- •Many CBT-I providers don't take insurance, and wait lists are long
- •Mason uses group visits of eight patients and a pre-treatment video that warns of early difficulty
- •She is helping an app called Rest that incorporates AI and her wake-time method
- •Patients awake at night should leave bed for a mildly boring, non-stressful activity
- •Work, social media, and current events are off the menu; short sitcoms or novels are fine
- 1:26:22 – 1:32:29
Food, alcohol, and cognitive tools like tracking belief in thoughts
Peter asks about food and alcohol. Mason asks for no eating within three hours of bed and a consistent, reduced alcohol intake during treatment. She explains that cognitive work starts in week three, including tracking how strongly a thought is believed throughout the day.
- •Mason asks patients not to eat within three hours of bed
- •Patients cut or stabilize alcohol during treatment to see sleep with minimal perturbation
- •Cognitive techniques begin in week three of five
- •Tracking belief in a worry across the day shows that 1 a.m. thoughts often fade by afternoon
- •An MS patient's dreaded 7 a.m. thoughts shrank by evening, and she used the time to learn Italian
- 1:32:29 – 1:37:37
Sleep supplements and melatonin
Peter raises sleep supplements, and Mason says she generally takes patients off them during treatment, noting weak data for ashwagandha and melatonin and doubts about supplement contents. She says melatonin can mistime sleep, but a small dose can help patients on beta blockers.
- •Mason asks patients to stop supplements so she can see what the body does
- •Data on ashwagandha and melatonin are weak except in certain cases
- •Beta blockers inhibit melatonin secretion and can cause insomnia
- •Melatonin signals when to start sleep and does not keep you asleep
- •Taking it can push people to sleep before their body is ready
- 1:37:37 – 1:51:46
Sleep medications and slow tapering of Ambien and benzodiazepines
Mason describes the sleep drugs patients want to quit, including benzos, Ambien, Benadryl and Remeron, and discusses trazodone. She explains her taper approach: coordinate with the prescriber, stabilize first, use a distress scale, and reduce in tiny increments after CBT-I.
- •Mason sees Ambien dosing sometimes far beyond FDA guidance, and women's recommended starting doses are lower
- •She is less worried about trazodone, though it may be treating depression
- •She always works with the prescribing physician
- •Patients stabilize on one consistent dose before tapering
- •Reductions are paced by a subjective distress scale, using a gem scale for tiny doses, and paused during life crises
- 1:51:46 – 1:59:24
Screening for other sleep disorders and keeping a consistent wake time
Peter asks what must be ruled out before CBT-I, such as sleep apnea. Mason describes screening questions and referrals, then stresses anchoring the wake time over the bedtime, and explains how to handle late nights by choosing which day to suffer.
- •Referrals often come from sleep centers that have done the workup
- •Mason screens for snoring or gasping and pushes patients to use CPAP
- •You can fix a wake time but cannot force a bedtime
- •During treatment, wake time stays the same every day, including weekends
- •After a late night, sleep in only one day and choose which day to prioritize
- 1:59:24 – 2:05:24
Process S, Process C, and exercise close to bedtime
Mason briefly explains sleep homeostasis (Process S) and the circadian process (Process C), and why napping and caffeine interfere. Peter then asks about evening exercise, and she says it depends on the person, fitness, and type of exercise.
- •Process S is sleep pressure that builds during the day and drains during sleep
- •Naps deflate sleep pressure, and caffeine blocks adenosine receptors
- •Process C is circadian timing that runs regardless of sleep pressure
- •CBT-I mainly works on sleep pressure by regularizing schedules
- •Evening exercise depends on fitness and heart-rate recovery; yoga is fine, HIIT late at night is better moved earlier
- 2:05:24 – 2:11:57
CBT-I structure, measurement, finding a therapist, and self-help options
Peter asks how standardized CBT-I is. Mason explains her measured, weekly, formulaic approach using the PSQI and Insomnia Severity Index, and the five core components. She advises seeking weekly sessions, using a directory, and trying the book Quiet Your Mind and Get to Sleep or apps.
- •Mason measures outcomes with the Pittsburgh Sleep Quality Index and Insomnia Severity Index
- •The five components are time in bed restriction, stimulus control, cognitive techniques, relaxation, and sleep hygiene
- •Weekly sessions matter because changes are based on weekly sleep diaries
- •Quiet Your Mind and Get to Sleep can be used alone or with a provider
- •Telemedicine has made therapists far more accessible
- 2:11:57 – 2:14:32
Sauna, cold plunge, and heat before bed
Peter asks about sauna, cold plunge, and hot baths before bed. Mason rules out cold plunges before bed, says sauna depends on heart-rate recovery and timing, and describes an NIH-funded trial combining whole-body heating with app-based CBT-I.
- •Cold plunge before bed makes the body work to rewarm and is not advised
- •Sauna may help via a temperature gradient but can raise heart rate in people who don't recover quickly
- •Drinking lots of water after sauna can cause more nighttime waking
- •Mason is running a trial combining home whole-body heating with app-based CBT-I
- 2:14:32 – 2:21:17
Closing takeaways: no one should have to suffer from insomnia
Peter says he found the conversation a master class and notes CBT-I's strong results among patients who comply. Mason urges listeners not to wait or worry about the cause, and the two discuss telemedicine access and a possible part two.
- •Peter says nobody should have to suffer from insomnia
- •You don't need to know what caused your insomnia to start CBT-I
- •Mason urges starting now because there is never a convenient time
- •Telemedicine and licensing compacts like PSYPACT widen access
- •Mason advises following the treatment as written rather than feeling like a delicate flower
