THE ALCOHOL COMPARISON 🍷
Drew Dawson And Kathryn Reid Ran The Test In 1997
Their Results Went Into Nature That Year
Volunteers Stayed Awake For Up To Twenty Eight Hours
Others Drank Until They Reached Measured Alcohol Levels
Both Groups Sat The Same Hand Eye Coordination Tests
Each Extra Hour Awake Matched 0.004 Percent Alcohol
Seventeen Hours Awake Landed At 0.05
At Twenty Two Hours It Reached 0.08
Twenty Four Hours Reached 0.10
Many Countries Set The Driving Limit At 0.05
A Normal Day Ending At Midnight Reaches Seventeen Hours
Nobody Gets Stopped For It
The Comparison Covers Coordination And Reaction Speed
It Does Not Mean Tiredness And Alcohol Are The Same Thing
Alcohol Leaves A Reading On A Breathalyzer
Sleep Loss Leaves Nothing To Measure At The Roadside
That Difference Runs Through Everything Written About This
Impairment Without Evidence Is Still Impairment

THE FOURTEEN DAY EXPERIMENT 🧪
Hans Van Dongen And David Dinges Ran The Larger Study
Forty Eight Healthy Adults Moved Into A Laboratory
Sleep Was Controlled Rather Than Self Reported
Each Person Got Four Six Or Eight Hours In Bed
The Same Schedule Held For Fourteen Straight Nights
Every Day They Sat A Simple Reaction Time Test
A Light Appears And You Press A Button
The Test Measures Attention Rather Than Skill
Eight Hour Sleepers Scored The Same On Day Fourteen
Six Hour Sleepers Scored Slightly Worse Each Day
Four Hour Sleepers Dropped Faster
Neither Group Ever Stopped Declining
Two Weeks At Six Hours Matched Two Nights Without Sleep
Researchers Also Asked How Sleepy Everyone Felt
Those Ratings Rose For A Few Days Then Stopped
Six And Four Hour Sleepers Reported Feeling About The Same
Their Scores Were Nowhere Near The Same
People Could No Longer Judge Their Own Impairment
