Sleep accelerator
A bedside device that accelerates the sleeper's circadian rhythm. This speeds up sleep, but consumes a lot of electricity and also causes increased hunger. It must be placed directly adjacent to and facing the head of the bed. Placing more than one sleep accelerator near the same bed has no effect.

A Sleep accelerator is miscellaneous building added by the Ideology DLC. It increases the rate at which a pawn sleeps, giving them a longer working day, in exchange for increasing the amount of nutrition they require and consuming power.
Acquisition
Sleep accelerators can be constructed once the Microelectronics research project has been completed. They require 50 Steel, 5 Components, 6,000 ticks (1.67 mins) of work, and a Construction skill of 8. Sleep accelerators can only be constructed by colonists with an Ideoligion containing the Transhumanist meme.
Summary
Sleep accelerators can be installed to a bed, granting +35% Rest Effectiveness and +20% Hunger Rate Multiplier to the colonist sleeping in it for 400W power. Note that this Rest Effectivenes bonus is applied before the quality multiplier on Rest Effectiveness of the bed, that is the bonus is multiplied by the bed's quality Rest Effectiveness Factor. It is applied after the multiplier from being a bed being made of stone. It takes 50W power when it's not being used.
As noted by the description, the sleep accelerator must be placed adjacent to and facing the head of the targeted bed to have effect. More than one accelerator has no effect. A double or royal bed only requires a single accelerator to affect both pawns.
The following beds can utilize the sleep accelerator: Bed, Bedroll, Double bed, Double bedroll, Hospital bed, Royal bed, Slab bed, Slab double bed.
| Bed Quality | Awful | Poor | Normal | Good | Excellent | Masterwork | Legendary |
|---|---|---|---|---|---|---|---|
| Rest Effectiveness Bonus | +30% | +32% | +35% | +38% | +40% | +44% | +56% |
Nota bene: As the rest effectiveness bonuses apply to the bed before the bed's quality multiplier is applied, the exact bonus the sleep accelerator applies scales with the bed's quality.
Pawns with a Transhumanist ideoligion will gain a +3 moodlet for 24 hours whenever they sleep with a sleep accelerator.
Analysis
 | This section is a stub. You can help RimWorld Wiki by expanding it. Reason: Needs proper analysis with actual gained time for different bed qualities, as well as effects when combined with other sleep accelerating options such as bionics, circadians, etc.. |
When sleeping in a normal quality bed, sleep accelerators will save 1.4 hours of sleep (5.8% of a day). In a masterwork bed, this is reduced to saving 1.25 hours (5.2% of a day). While this might seem paradoxical considering the accelerator's increased Rest Effectiveness, there is just less time in a single day to save.
Consequently, other means of sleep reduction, like psychite tea, bionic hearts, circadian assisant
, or the Low sleep gene
, will all reduce the relative impact of the sleep accelerator. However, with multiple means of sleep reduction, pawns will start to go "beyond" a 24 hour sleep cycle. In this scenario, setting their schedule to all Anything will reduce the time pawns travel to and from bed, increasing efficiency in a different way.
The power draw is significant and spikes while colonists sleep. If a pawn sleeps for 6 hours a day and batteries are used, then an average of roughly 170 W per day if said power is constantly supplied. Batteries will only store 50% of any excess power. So if solar generators are used while colonists sleep at night, then more power is required, up to the upper limit of 200 W per accelerator.
Pawns in a double bed can share a sleep accelerator, so you may want to pair pawns up. Manipulating their actions, using the "Romance" option in the Social tab, and/or using the Word of Love psycast can all help power. If you're using solar generators, then you may want to have pawns sleep in the day in order to ignore the battery's 50% penalty and use the generator's full draw of power. If you are doing this, remember that light impacts both movement and work speed.
Overall, the sleep accelerator is a consistent +5% or so buff to a Transhumanist's work efficiency, once you can afford the resource and power cost. Once high expectations are met, Transhumanists will demand age reversal, which takes a minimum of 2.61 days/year, or 4.31% of the year when tuned in a sterile room. In a regular, clean room, this takes 3 days/year (5% of the year). Transhumanists also have access to the neural supercharger, which is another power-hungry building that acts as a further increase to work.
