Daily Anger Has Been Tracked Worldwide For Nearly Two Decades

An Outburst Is Treated As The Emotion Itself

Anger Starts Well Before It Becomes Visible

Threat And Frustration Are What Trigger It

Sympathetic Nerves And Adrenal Hormones Produce The Response

Researchers Have Traced Anger To A Threat System In The Brain

Not Every Anger Response Becomes An Aggressive Act

Damage To The Frontal Cortex Makes Anger Harder To Regulate

OKAY BACK FROM THE SURVEY DESK 📊

Gallup Runs A Continuous Survey Called The World Poll

Its Interviewers Survey Residents In More Than 140 Countries

The Poll Covers More Than 98% Of The World's Adult Population

Samples Are Randomly Selected And Nationally Representative

In 2024 The Survey Covered 144 Countries And Territories

Gallup Published The Numbers On 12 October 2025

Interviewers Ask Whether A Person Felt Anger The Previous Day

22% Of Adults Said They Had

Worry Was Reported By 39% Of Adults

Stress Was Reported By 37%

Physical Pain Was Reported By 32% And Sadness By 26%

Anger Was The Lowest Of The Five Negative Emotions Measured

Gallup Compared Those Figures With A Decade Earlier

Every Negative Emotion Was At Least Four Percentage Points Above 2014

Anger Showed No Change From The Previous Year

Gallup Recorded The Highest Anger In Chad And Jordan And Armenia

Northern Cyprus And Sierra Leone And Iraq Followed Them

Those Places Are Marked By Conflict Or Political Instability

The Report Also Separated The Figures By Age And By Gender

Younger Adults Are More Likely Than Older Adults To Feel Daily Anger

More Women Than Men Have Reported Daily Anger For Nearly Two Decades

Researchers In Valencia Induced Anger In 30 Healthy Men

Each Volunteer Read 50 Self Referent Statements From A Binder

The Instruction Was To Read Each Sentence Silently

One Statement Ran I Am Consumed With Hatred

Self Reported Anger Scores Were Significantly Higher Afterwards

Heart Rate Rose From 71.73 To 74.93 Beats Per Minute

Diastolic Pressure Rose From 70.37 To 72.63 Millimetres Of Mercury

Systolic Pressure Showed No Significant Change

Salivary Testosterone Was Higher After The Induction

Cortisol Measured In The Same Saliva Fell

The Authors Call The Cortisol Finding More Controversial

Earlier Work Separated The Anger Pattern From The Fear Pattern

Fear Raises Heart Rate And Systolic Pressure

Diastolic Pressure Stays Relatively Low In Fear

Anger Raises Both Of Those And Peripheral Vascular Resistance

That Resistance Is What Lifts Diastolic Pressure

Those Cardiovascular Changes Are Part Of Something Wider

A Stress Response Has A Fast Component And A Slow One

The Fast One Runs Through The Nerves And The Adrenal Medulla

Noradrenaline And Adrenaline Enter The Circulation

Both Hormones Bind Receptors On Smooth And Cardiac Muscle Cells

Blood Pressure And Heart Rate And Cardiac Output All Rise

The Slow Component Starts In The Hypothalamus

Corticotropin Releasing Hormone Goes Into The Circulation

That Hormone Stimulates The Anterior Pituitary To Release ACTH

ACTH Stimulates The Adrenal Cortex To Secrete Cortisol

A Review Calls Reactive Aggression The Expression Of Anger

Reactive Aggression Follows A Frustrating Or Threatening Event

It Involves Unplanned Attacks On The Perceived Source

The Review Says It Appears In All Mammalian Species

Mammals Meet Threat In Stages That Depend On Its Distance

Distant Threat Induces Freezing

Closer Threat Induces Attempts To Escape

Very Close Threat With No Escape Initiates Reactive Aggression

Animal Work Places That Response In A Basic Threat System

It Runs From Medial Amygdaloidal Areas To The Medial Hypothalamus

From There It Runs To The Dorsal Half Of The Periaqueductal Gray

The System Is Organised In A Hierarchy

Aggression Evoked At The Amygdala Needs The Hypothalamus Intact

Stimulating The Periaqueductal Gray Does Not Need The Amygdala

Imminent Threat Produces Greater Periaqueductal Gray Activity

Several Regions Of Frontal Cortex Regulate That Threat System

Orbital And Medial And Ventrolateral Frontal Cortex Are Named

Induction Studies Report Increased Activity In Those Regions

Anger May Be Expressed When Those Regions Are Overwhelmed

Ventromedial And Ventrolateral Lesions Can Produce Acquired Sociopathy

Patients With Those Lesions Struggle To Regulate Their Anger

The Same Association Appears In Healthy Populations

A Predisposition To Anger Is Associated With Larger Amygdala Volume

It Is Also Associated With A Stronger Amygdala Response To The Word No
