Sleep is a derived statistic in Fallout 3, Fallout: New Vegas and Fallout 4.
Characteristics
Sleep is a consequential statistic of the total time spent awake: the longer one is awake, the higher the sleep value becomes. Beverages containing caffeine will reduce this value, as will sleeping typically in a bed.
Fallout 3
In Fallout 3, Sleep modifies Hit Points.
Fallout: New Vegas
In Fallout: New Vegas, sleep is measured in hardcore mode as SLP in the Pip-Boy 3000. Sleeping in an owned or rented bed will give the Well Rested bonus for 12 hours. As sleep deprivation worsens, stats will be negatively impacted, starting with Agility. Not sleeping for two weeks equals death.
Stages of SLP
| Stages | Value | Effects |
|---|---|---|
| Minor Sleep Deprivation | 200-399 | Agility -1 |
| Advanced Sleep Deprivation | 400-599 | Intelligence -1, Agility -2 |
| Critical Sleep Deprivation | 600-799 | Endurance -1, Intelligence -2, Agility -3 |
| Deadly Sleep Deprivation | 800-999 | Endurance -2, Intelligence -2, Agility -3 |
| Fatal Sleep Deprivation | 1000 | DEATH |
| Name | Level req | Other requirements | Benefit |
|---|---|---|---|
| Home on the Range | 8 | Survival 70 | Whenever you interact with a campfire, you have the option of sleeping, with all the benefits that sleep brings. |
| Irradiated Beauty | 22 | Endurance 8 | Sleeping removes all rads on normal mode/Removes 100 rads on hardcore mode. |
| Roughin' It | 28 | Survival 100 | Well Rested bonus when you sleep outside, including in unowned beds. |
Notes
- Although there are some consumable items that help reduce SLP deprivation, attempting gameplay without sleep may not be possible unless being prepared to skip a few quests that require sleep. The effects of not sleeping, that is surviving on caffeine based consumables or chems, is uncertain, however, no known ill effects have been reported.
- In Hardcore mode, Completing the initial quest of any of the DLC packs will bring the SLP meter to 0 and disable it. Otherwise, the lowest value that can be achieved through normal means is 2.
Bugs
Sometimes the SLP meter on the Pip-Boy 3000 can get stuck on zero, and in fact will not display any number below the indication arrow. This is normally caused by travelling through canyon wreckage, which sets all hardcore meters to zero. During this time the PC will not advance into sleep deprivation. This bug may be fixed by finding a bed and sleeping for any amount of time. After the PC awakes, the gauge will display the number and resume its normal function. [verified]
Fallout 4
In Fallout 4, Sleep modifies Fatigue in Survival mode. Sleep deprivation is displayed as an icon just below the AP bar. If sleep deprivation is left untreated it will directly impact available action points (AP) and SPECIAL stats.
Stages of sleep deprivation
| Stages | Duration in-game hours (real-time mins) | Effects |
|---|---|---|
| Tired | 27 hours (61 mins) | AP Refresh -5% |
| Overtired | 40 hours (120 mins) | Strength-1, AP Refresh -15% |
| Weary | 55 hours (165 mins) | Agility -1, Luck -1, Strength -2, AP Refresh -30% |
| Exhausted | 69 hours (207 mins) | Agility -2, Luck -2, Strength -4, AP Refresh -50%, Can't Sprint |
| Incapacitated | 82 hours (246 mins) | Agility -4, Luck -3, Strength -6, AP Refresh -75%, Can't Run |

Notes
- To get the full benefits of sleep you will need to sleep in a real bed, as a sleeping bag will slowly get rid of sleep and eventually will stop helping altogether.
- In Survival mode sleeping is the only way that the game can be saved.
- In Survival mode, the Sole Survivor cannot sleep more than 3 hours in a sleeping bag and more than 5 hours on a mattress. To sleep for longer amounts of time, it is required to use a real bed.
