Bryan Johnson calls himself a professional
sleeper.
He goes to bed at 8:30pm every night. He
tracks his sleep with a wearable device.
He has achieved what he describes as eight
months of consecutive perfect sleep scores.
Sleep is not an afterthought in his protocol.
It is the foundation everything else is
built on.
Here's what he actually does — and what
UK adults can realistically implement.

WHY SLEEP MATTERS SO MUCH
Johnson's approach to sleep is backed by
straightforward biology. During deep sleep
your body releases growth hormone, repairs
tissue, consolidates memory, and clears
metabolic waste from the brain through the
glymphatic system.
Poor sleep raises cortisol, impairs insulin
sensitivity, accelerates cellular ageing,
and undermines every supplement and
intervention you stack on top of it.
In Johnson's view no supplement compensates
for poor sleep. It is non-negotiable.

WHAT BRYAN JOHNSON'S SLEEP PROTOCOL
ACTUALLY INVOLVES
Consistent sleep and wake times
Johnson goes to bed at 8:30pm and wakes
naturally without an alarm at around 5am.
The consistency matters as much as the
duration — his circadian rhythm is tightly
regulated.
No screens two hours before bed
He enters what he calls night time mode
at around 6:30pm. No messages, no social
media, no screens. This is non-negotiable
in his protocol.
Blue light blocking glasses from early evening
Johnson wears blue light blocking glasses
to filter the blue light that suppresses
melatonin production. He puts them on
well before his screen cutoff as an
additional layer of protection.

Temperature regulation
He sleeps in a cool room. Lower core body
temperature is associated with deeper sleep
and faster sleep onset. Many people sleep
too warm without realising it.
Low dose melatonin
Johnson takes 300mcg of melatonin before
bed. This is a very low dose — far lower
than the 5-10mg commonly sold in the US.
In the UK melatonin is prescription only
so this element of his protocol is not
directly replicable without a GP
conversation.
No food after 11am
Johnson eats all his calories before noon
as part of his time-restricted eating
protocol. Digestion disrupts sleep quality.
He gives his body 17+ hours to complete
digestion before sleeping.
Tracking
He tracks sleep duration, sleep stages,
and heart rate variability every night.
Wearables like the Oura Ring or Whoop
are the most popular options for this
in the UK.

WHAT UK ADULTS CAN REALISTICALLY DO
You probably cannot go to bed at 8:30pm.
Most people have jobs, families, and social
lives that make Johnson's schedule
impossible.
But the principles are accessible.
Pick a consistent bedtime and stick to it
seven days a week. Even if it is 11pm.
Consistency matters more than the specific
time.
Stop using screens an hour before bed.
Not two hours — just one. That alone will
make a measurable difference for most
people.
Wear blue light blocking glasses from
around 8pm. This is low effort, low cost,
and has solid evidence behind it. Your
melatonin production will thank you.
Bio-Sync Blue Light Blocking Glasses
— £24.99. UV400 protection. Sleep and
screen protection in one.
Keep your bedroom cool. 16-19 degrees
Celsius is the research-backed optimal
range for sleep.
Avoid eating within three hours of bed.
You do not need to eat before noon like
Johnson. Just stop eating closer to
bedtime.

THE ONE THING WORTH PRIORITISING FIRST
If you only do one thing from Johnson's
sleep protocol make it the blue light
blocking glasses.
It costs £24.99. It takes zero willpower.
You put them on in the evening and your
melatonin production stays on track.
Most people notice a difference within
a week.
Everything else in the protocol builds
from there.
