Sanity Guide — How It Works & How to Restore It
Sanity is your real health bar. Once it hits zero, your shift ends — even if you never got touched by a monster. Here is everything verified about draining and restoring it.
Community-compiled values (Fandom, post-June 19 patch). Developers have not released the full Sanity curve; treat numbers as estimates.
Sanity Basics
Default starting Sanity
~61–65%
Intern starting Sanity
~71–75%
Danger threshold
Music slows below ~35%
What Drains Sanity
| Source | Value / Rate |
|---|---|
| Jumpscare | Significant amount (exact values not disclosed by developers) |
| Cursed photo | Approx. −10 |
| Staring at the enemy | Continuous drain |
| Candle / Fire | Approx. −1/sec |
| Melee combat | Drains Sanity continuously |
How to Restore Sanity
| Source | Value / Rate |
|---|---|
| Coffee (shop) | +15 |
| Chocolate (shop) | +60 |
| Free coffee machine | +15 per cup, ~180s cooldown |
| Large coffee machine | More cups, ~300s cooldown |
| Other food | Varies by food item |
| Class perks | Doctor/Surgeon heal Sanity; Intern starts with bonus Sanity |
Reduce Unnecessary Sanity Loss
- Block threats with the shutter, put fires out with the fire extinguisher, or stun enemies with a taser — don't tank damage with your face.
- Don't look directly at cursed photos (about −10 at once) or at staring enemies (continuous drain).
- Avoid melee combat when you can — it drains Sanity continuously.
- Keep Sanity above the music-slowing threshold; the slowdown is your last warning.
Frequently Asked Questions
What happens when Sanity hits zero in Animal Hospital?
Your shift ends. Sanity is the hidden failure condition — it is not restored through combat, and it drains slowly from the atmosphere, anomalies and events. Treat it as a resource you must actively maintain.
How do I know my Sanity is getting dangerously low?
The background music noticeably slows down below roughly 35% Sanity — that is your auditory warning. Head to a coffee machine, eat stored chocolate, or move away from the drain source.
What is the best value Sanity item?
Chocolate restores the most (+60) at about 2 Cash per Sanity point — better value than coffee (~3.67 per point), but pricier per unit. Use the free coffee machines for daily maintenance and keep chocolate for emergencies.
