Resting



Resting is used to heal in a safe place without the need to use stimpaks, buffout, healing consumables or healing perks/implants. The player is unable to rest if there are enemies nearby, when the area is exposed to radiation, or if the bed is owned by someone else.

Fallout and Fallout 2
In Fallout and Fallout 2, you can rest to recover your health in almost any place, as long as you're not in combat, using the Pip-Boy 2000 alarm clock function. A handful of places, such as the toxic caves or Vault City downtown, prohibit resting.

Fallout 3
Sleeping in a bed for any length of time will restore full health and heal all limbs, but will not get rid of radiation buildup. You cannot sleep in an owned bed (if the owner dies the bed won't revert to an un-owned state). Many places in the open wasteland have un-owned beds for players to use freely, however, most major settlements require you to rent a bed, which will give you the Well Rested bonus.

Alternatively, it is possible to wait in a certain location for however long you desire. Unlike sleeping, there is no benefit to this other than advancing the clock. It will not restore any health (unless you have the Solar Powered perk and are standing in the sun), and all the drawbacks still apply. It mainly serves the purpose of moving forward in time to a point where certain events will trigger, such as the open hours of a shop.

Well Rested
If you sleep in a bed you own or rent (such as in your Megaton house, Tenpenny Tower suite, Kenny's Cave, or a rented room) for an hour or more, you will become "Well Rested" and gain a 10% bonus to experience gained for 12 hours. The add-on Broken Steel adds the perk Deep Sleep, which gives you the bonus from sleeping in any bed (provided the rest of the conditions are met).

Bed locations

 * The article Fallout 3 player housing provides numerous locations with "free beds".

Hotels
Sleeping in these will provide you with the "Well Rested" bonus.
 * Megaton, Moriarty's Saloon, Nova, 120 caps.
 * Rivet City, Weatherly Hotel, 120 caps.
 * Underworld, Carol's Place, 120 caps.

Add-ons
The Point Lookout add-on provides an additional Well Rested bed in Kenny's Cave, provided you pass a speech check, have the Child at Heart perk, or retrieve Kenny's special teddy bear.

Fallout New Vegas
Beds act the same as in Fallout 3, but with some minor differences. In addition to owned beds conferring a Well Rested bonus, having sex with someone or sleeping in specific 'Queen' or 'Queen-sized' beds in certain locations will also confer the bonus. In Hardcore mode, the healing benefits of a bed only apply to owned beds; other beds in the Wasteland will reduce sleep but not restore any health.

Alternatively, with a high Survival skill, the perks Home on the Range and Roughin' It allow the Courier to sleep via interaction with a campfire or in an unowned bed respectively. Also, the Roughin' it! bedroll kit is essentially a portable bed.
