Alcohol May Sedate You but Damages Restorative Sleep

Using alcohol after several disrupted nights can appear to solve sleep onset while degrading sleep quality. Breus says it destroys stage-three sleep, the stage associated with physical restoration, so drinking oneself to sleep is not a sound fix.

  • Sedation is not the same as healthy sleep
  • Alcohol damages stage-three sleep
  • Physical restoration suffers even if sleep onset feels easier

Alcohol destroys stage three for sleep, which is the physical restoration.

Dr. Michael Breus · 11:00

So this is where people usually use alcohol, right? Bad idea.

Why Breus Warns Against Nightly Benadryil for Sleep

Breus strongly warns against consistent nightly use of Benadryil or sleep products containing the same antihistamine. He distinguishes habitual use from occasional use and advises addressing the underlying sleep problem with a clinician instead.

  • Many PM sleep products contain the same antihistamine
  • Breus links consistent anticholinergic use to Alzheimer's risk
  • His warning targets regular nightly use rather than rare use
  • Persistent insomnia warrants clinical investigation

there is direct evidence to show that consistent use of benadryil on the nightly as an antiolinergic leads directly to Alzheimer's.

Dr. Michael Breus · 16:30

If you use it once in a while, it's not you're not going to have Alzheimer's. I'm talking about people who have to have one…

Melatonin Is a Hormone, Not a Harmless Nightly Default

Breus limits his preferred melatonin use cases to jet lag, shift work, REM behavior disorder, and genuine deficiency, including age-related decline. He warns that melatonin can interact with birth control, SSRIs, blood-pressure medication, and diabetes medication, and says it is not for children.

  • Jet lag and shift work are specific use cases
  • Age-related deficiency may justify supplementation
  • Melatonin can interact with several medications
  • Breus advises against giving it to children
  • Treat melatonin as a hormone rather than a benign root

Melatonin is not for children. Period. Full stop.

Dr. Michael Breus · 22:00

So, it's a hormone. It's not just this root that we're getting from somewhere.

Hot Take· 1

Hot Take15:30

A Sleep Pill Can Solve One Problem and Create Another

Breus acknowledges that sleep medications have benefits as well as drawbacks. Even when a newer pill is not physiologically addictive, the experience of finally sleeping well after years of insomnia can create strong psychological reliance.

  • Sleep medications have both pros and cons
  • Lack of physiological addiction does not remove psychological reliance
  • Repeated pill use can become attached to confidence in sleeping

then you got a sleep problem and a pill problem.

Dr. Michael Breus · 16:00

if you haven't slept well in 20 years and I give you a pill, you're g you're gonna want that pill again and again and…

Why People Naturally Wake Between 1 and 3 a.m.

Breus says core body temperature falls after its nightly peak and eventually has to rise again. That increase commonly produces a brief awakening between 1 and 3 a.m., but many people return to sleep before becoming consciously aware of it.

  • Core body temperature rises before beginning its nightly decline
  • A later temperature increase commonly triggers a brief awakening
  • Awareness requires being awake for roughly 45 seconds

every human on Earth wakes up

Dr. Michael Breus · 02:00

most people don't even know that they've woken up because you have to be awake for about 45 seconds to actually realize that you're awake

CBD, CBN, and THC Play Different Roles in Sleep

Breus distinguishes the major cannabis components rather than treating gummies as one category. He says CBD may indirectly help when pain or anxiety blocks sleep, CBN has evidence related to nighttime awakenings, and higher THC can reduce REM sleep and raise heart rate.

  • CBD is framed as support for pain or anxiety rather than sleep itself
  • CBN is the component Breus associates with fewer awakenings
  • High THC may lower REM sleep and increase heart rate
  • Cannabis is optional, not required for better sleep

CBD does almost nothing for your sleep. However, CBD is good for pain and it's good for anxiety.

Dr. Michael Breus · 12:00

THC at high amounts will lower your REM sleep and increase your heart rate, which we don't want either one of those.

Omegas May Support Sleep Indirectly, Not Target One Stage

Breus says omega supplements support broader cellular functions that relate indirectly to sleep. He notes that studies have not isolated an improvement in a particular sleep stage, but regular users have reported higher overall sleep quality.

  • Omegas support cell membranes and broader body functions
  • Evidence has not isolated one improved sleep stage
  • Regular use is associated with reported sleep quality rather than a precise stage effect

omegas, they help with a whole host of different functions in our body, which then relate to sleep.

Dr. Michael Breus · 23:30

what we have seen is when people take omegas regularly that they actually report higher quality sleep.

Yoga Nidra Can Make Wakeful Rest Less Frightening

Breus presents yoga nidra, also called non-sleep deep rest, as a rejuvenating fallback when sleep will not return. He says lying still with eyes closed and breathing is not equivalent to sleep, but can reduce the fear that wakefulness is entirely wasted.

  • Lie relaxed in bed with eyes closed
  • Use a corpse-pose-like resting position
  • Treat quiet rest as beneficial without pretending it is sleep

some people call it non-sleep deep rest. I call it yoga nidra.

Dr. Michael Breus · 08:30

Now it's not the same as sleep, but it's probably worth 30% sleep.

The Gentler Sleep Supplements Breus Discusses

For people avoiding antihistamines, cannabis, and alcohol, Breus names several supplements he considers relatively gentle. He describes GABA as slowing thought and anxiety, valerian root combined with hops as a studied sleep aid, and ashwagandha as potentially useful for anxiety.

  • GABA may slow racing thoughts and anxiety
  • Valyan root is discussed in combination with hops
  • Ashwagandha is presented as anxiety support
  • Supplement choices should follow root-cause assessment

GABA is kind of like the breaks of the brain. It definitely can help you slow down your thinking, lower your anxiety.

Dr. Michael Breus · 19:00

Valyan combined with hops has been shown to be actually quite effective, as effective as sleeping pills in some cases.

Acceptance Breaks the 3 a.m. Catastrophe Loop

Breus argues that a bad night feels more dangerous at 3 a.m. than it really is. Remembering that the body has survived this state before can reduce catastrophic thinking and the pressure to force sleep.

  • Do not treat one awakening as an emergency
  • Recall that previous bad nights were survivable
  • Avoid making major judgments while tired and anxious
  • Trust the body's changing nightly sleep needs

You've actually were here last night. Okay? And guess what? Your head didn't pop off. Nothing terrible happened.

Dr. Michael Breus · 10:00

you don't make great decisions at 3:00 in the morning when you're thinking about those kind of things.

Test Three Nutrient Deficiencies Before Chasing Sleep Aids

Breus prioritizes fixing the body's measured deficiencies over blindly adding sleep supplements. He recommends discussing blood work with a doctor and checking vitamin D, magnesium, and iron before deciding what intervention is needed.

  • Start with blood work rather than supplement guesses
  • Check vitamin D, magnesium, and iron
  • Correct measured deficiencies first
  • Reassess sleep after the body is operating from a healthier baseline

I'm not a big supplement guy when it comes to sleep. I'm a big let's fix the body guy.

Dr. Michael Breus · 18:00

Vitamin D, uh, magnesium, and iron. If you are deficient in any one of those three, there's no universe that you're getting a good night's…
