Hungry, Angry, Lonely, Tired. An unmet physical need can pass for a mood and steer your next decision. HALT is a ten-second body scan to check for one first.

The mechanism at a glance. Energy is a reservoir. Rest is an inflow, not a reward, and the floor is not optional.
Before you conclude that you are anxious, check whether you are hungry. Before you conclude that you are depressed, check whether you are exhausted. Before you conclude that you are angry at your partner, check whether you are lonely.

SHORT ANSWER
HALT stands for Hungry, Angry, Lonely, Tired. Before reacting to a strong emotion or making a decision, you run the four letters as a quick body scan: am I hungry, angry, lonely, or tired? It comes from twelve-step recovery, where it is a reminder for people in recovery, and it points at the idea that body signals feed into emotion. HALT itself has little direct research behind it, so treat it as a prompt, not a diagnosis. Sometimes the anxiety is hunger or the low mood is exhaustion, and sometimes it is not. Meet the need first, then reassess the emotion. If the feeling stays, take it seriously.

The problem
It's 4 p.m. The email reads as hostile. Your partner's tone feels like an attack. The decision in front of you feels urgent and obvious. So you fire back, or you commit, or you spiral, and an hour later, fed and rested, you can't believe you read it that way.
The feeling was real. The interpretation was a hijack. An unmet physical need (low blood sugar, no real sleep, no genuine connection in days) doesn't politely announce itself. It can dress up as a mood and steer your next move. And we tend to trust the mood and blame our character.
HALT is the interrupt. Four letters, ten seconds, before you react.
The mechanism
HALT (Hungry, Angry, Lonely, Tired) comes from twelve-step recovery, where it is a self-check before high-stakes moments, and SAMHSA's Treatment Improvement Protocol 65 (2023) lists it for people in recovery. The mnemonic itself has little direct research behind it: a 2026 review (Kretchman) says so. What it points at is interoception, which has a much larger literature.
Interoception is the perception of your internal physiological state: hunger, fatigue, heart rate, the felt sense of the body. It involves the insular cortex, and Antonio Damasio (1999) argued that the feelings you call "emotions" are built partly out of body signals.
Sometimes a body signal that goes unnoticed gets read as an emotion. In one 21-day diary study of 64 adults, hungrier moments came with more anger and irritability (Swami et al., 2022). In a larger study of 748 adults, hunger was not linked to sadness, anxiety or anger (de Rivaz et al., 2022). So the link holds for some people some of the time; it is not a rule, and this page cites no study for tiredness or loneliness playing the same role. In a lab experiment, hunger made people judge a researcher more negatively only when they were not aware they were reading their state as an emotion (MacCormack & Lindquist, 2019). Price and Hooven (2018) set out how interoceptive awareness skills could support emotion regulation; that is a theory paper on a body-oriented therapy, not a test of HALT. HALT is a deliberately simple scan: a structured prompt to check the body before you trust the feeling.
The operating system
Five steps. The middle three are the four letters; the bookends are what make it work.
STEP 01
Stop before you react
The moment you notice a strong emotion or an urgent decision, pause before acting on it. Not forever, just long enough to run the check. The pause itself is the intervention; everything else fits inside it.
Tie it to a trigger: any time you're about to send a heated message or say a hard yes/no, HALT first.
STEP 02
Run the four letters
Scan, in order. Hungry: when did I last eat, and is my blood sugar stable? Angry: is there an unaddressed grievance or crossed boundary? Lonely: when did I last have genuine connection? Tired: am I running on caffeine and willpower instead of rest?
Ask all four even if the first one lands. People are often two at once: hungry and tired, or lonely and angry.
STEP 03
Name which is firing
Say it plainly to yourself: "I'm not actually furious, I haven't eaten since breakfast." Naming the likely need can loosen the grip of the emotion, because it moves the problem from your character to your body.
If none of the four is firing, that's useful too: the emotion is probably real and worth taking seriously.
STEP 04
Meet the need first
Address the physiology before the feeling. Eat something. Step away from the trigger. Text the person you can be honest with. Lie down for twenty minutes. The need is concrete and usually quick to fix.
Hold the decision until the need is handled. Whatever feels urgent at 4 p.m. on an empty stomach can usually wait twenty minutes.
STEP 05
Reassess the emotion
Once the need is met, check the feeling again. It may have shrunk. What is left after the need is handled is the signal worth acting on, and you can respond to it with a steadier head.
If the feeling holds after HALT, trust it. HALT clears the noise so the real signal is easier to hear.

HALT · BEFORE YOU REACT
Ten seconds. Scan the body before you trust the mood.
H · HUNGRY
When did I last eat? Is my blood sugar stable?
Hunger can read as irritability.
A · ANGRY
Is there an unaddressed grievance or crossed boundary?
Name it instead of leaking it.
L · LONELY
When did I last have genuine connection?
Unmet, it can read as resentment at whoever's near.
T · TIRED
Am I running on caffeine and willpower instead of rest?
Exhaustion can read as hopelessness.
THEN
Meet the need first. Hold the decision. Reassess the emotion.
Sometimes the feeling eases. If it holds, trust it.

Hungry, Angry, Lonely, Tired. It's a quick self-check before reacting to a strong emotion or making a decision. It comes from Alcoholics Anonymous and twelve-step recovery, and SAMHSA's Treatment Improvement Protocol 65 (2023) lists it as a reminder for people in recovery.
Is there evidence that HALT works?
Not much, directly. A 2026 review of the framework (Kretchman) found little research on HALT itself. It points at interoception, the perception of internal body states, and Antonio Damasio argued in 1999 that feelings are built partly from the brain's reading of the body. Studies on hunger and mood disagree: one 21-day diary study found hungrier moments came with more anger and irritability, and a larger study of 748 adults found no link between hunger and sadness, anxiety or anger. Use HALT as a cheap prompt to check the body before you trust a feeling, not as a proven treatment.
How do I use HALT day to day?
Before reacting to any strong emotion, ask four questions: Am I hungry (when did I last eat)? Am I angry (is there an unaddressed boundary)? Am I lonely (when did I last really connect)? Am I tired (am I running on caffeine instead of rest)? Address the need first, then reassess the emotion.
Who benefits most from HALT?
Anyone who tends to notice the feeling before the body signal under it. That may include some people with alexithymia (difficulty identifying emotions) or trauma histories that disconnect mind from body, for whom a structured prompt to scan physical needs can be easier than reading the emotion directly. That is a reasonable guess, not a tested result for HALT. Price and Hooven (2018) describe interoceptive awareness skills as a route to emotion regulation, in a theory paper on a body-oriented therapy.

We cite peer-reviewed work by its DOI, so each reference above opens the article itself.
Where a framework's owner published a book rather than a paper, we name the author, year

and his 2023 reply to its critics,
and Fisher and Ury's Getting to Yes (Penguin).
Where we have no peer-reviewed article, we name the framework's author and say so.
