Bryan Johnson's Eight Sleep: His Bed Temperatures and Cheaper Alternatives (2026)
By ProtocolPicksPublished
What Bryan Johnson's protocol says about bed and bedroom temperature, the Eight Sleep settings listed for him, and two bed-cooling systems on Amazon that cost less. Scope: This summarizes his protocol and Eight Sleep's own Blueprint page. Eight Sleep is not sold on Amazon, and neither alternative here is his. It is not medical advice.

What the sources show
What his protocol says
The sleep section of his protocol asks for a quiet, dark, cool bedroom at about 65-70°F (18-21°C), and says temperature-controlled mattresses such as Eight Sleep are great. The "Stuff you may want" list at the end of the protocol includes an Eight Sleep bed. The protocol also lists a hot bedroom or high body temperature among the things that raise his resting heart rate at night.

The settings Eight Sleep lists for him
Eight Sleep's Blueprint page says he has used its Pod every night for years. It lists his bed at 71°F during deep sleep and 73°F during REM sleep. The page is a co-marketing page that also sells a Blueprint sleep supplement to Eight Sleep members, so treat it as the company's account. It does not say which Pod model he has.
Eight Sleep sells the Pod on its own site, not on Amazon, so there is no Amazon link for it here.

A water-cooled alternative: Chilipad
The Chilipad Cube ($629.10 on Amazon when we checked in October 2026) works the same basic way as Eight Sleep: a small bedside unit pumps temperature-controlled water through a pad on your mattress. It can be set from 60 to 115°F, which covers the 71-73°F listed for him. This listing covers one side of a queen bed, so two sleepers who want different settings need two. It has no sleep tracking and does not change temperature on its own through the night.
An air-based alternative: BedJet
BedJet ($509.98) blows air under your sheets through a hose from a bedside unit. It cools with room air and can also warm the bed. It fits any mattress, but it cannot make the bed colder than the room; the listing says it is not meant for rooms over 78°F without air conditioning. It works best alongside the 65-70°F bedroom his protocol already asks for.

Start with the room
Before spending hundreds of dollars on the bed, his protocol's cheaper basics cover a lot: set the thermostat to 65-70°F, make the room dark and keep it quiet. Blackout film and a sound machine handle the last two.
