## Learning Hub Articles

### How Long Until I'm Sober?
URL: /when-am-i-sober
Explains how the body eliminates alcohol at a fixed rate (~0.15‰/hour), why you can't speed up sobriety, and how to estimate when you'll reach zero BAC. Covers the difference between feeling sober and being sober.

### Why Do I Feel Anxious After Drinking? (Hangxiety)
URL: /hangover-anxiety
Explores "hangxiety" — the anxiety that follows drinking. Explains GABA rebound, cortisol spikes, and why the brain overcompensates after alcohol's sedative effects wear off. Includes coping strategies.

### Why Do My Drinking Goals Keep Failing?
URL: /drinking-goals-that-work
Analyzes why willpower-based and rigid rules (like "never more than 3") fail. Presents science-backed alternatives: flexible limits, tracking-based awareness, and identity-aligned goal setting.

### How Does Blood Alcohol (BAC) Change Over Time?
URL: /bac-over-time
Visualizes the BAC curve — absorption phase, peak, and elimination. Explains why BAC doesn't drop linearly and why reaching zero takes longer than most people expect.

### Why Can't I Stop at One Drink?
URL: /one-more-drink
Explains how alcohol impairs the prefrontal cortex, reducing self-control as BAC rises. Covers the neuroscience of "just one more" and practical pre-commitment strategies.

### Alcohol and Sleep: Why Drinking Ruins Your Rest
URL: /alcohol-and-sleep
Despite making you drowsy, alcohol fragments REM sleep, disrupts sleep architecture, and causes next-day fatigue. Explains the rebound effect and timing considerations.

### Only Drinking on Weekends: Why This Rule Often Backfires
URL: /weekend-only-rules
Calendar-based rules create artificial scarcity that can trigger binge behavior. Explores why rigid time-based rules fail and what flexible strategies work better.

### Why Do Hangovers Get Worse With Age?
URL: /hangover-tolerance
Explains how aging affects alcohol metabolism, liver enzyme efficiency, body composition, and recovery capacity — making hangovers progressively worse even at lower consumption levels.

### Alcohol and Nicotine: Why They Reinforce Each Other
URL: /alcohol-and-nicotine
Details the neurochemical loop between alcohol and nicotine through shared dopamine pathways. Covers cross-addiction mechanisms and strategies for breaking the reinforcement cycle.

### Why Does Alcohol Make My Heart Race?
URL: /alcohol-and-your-heart
Explains why alcohol triggers heart palpitations, racing heart the next day, and increased risk of atrial fibrillation. Covers "holiday heart syndrome," dehydration effects on heart rate, and when palpitations warrant medical attention.

### Can You Sober Up Faster? The Truth About Coffee, Food, and Cold Showers
URL: /sobering-up-myths
Debunks common myths about speeding up sobriety. Explains why coffee, food, cold showers, and exercise don't lower BAC — only time does. Covers the science of alcohol metabolism and why these myths persist.

## Interactive Tools

### BAC Calculator
URL: /tools/bac-calculator
Free, no account required. Estimate your blood alcohol content by entering your gender, weight, regional unit standard (Sweden, UK, USA, Canada, Australia, Denmark, France), and the drinks you've consumed (beer, wine, or spirits with adjustable size and ABV). Uses the Widmark formula with configurable metabolism presets. Results include: estimated BAC in ‰, BAC zone classification (green/yellow/orange/red), standard units consumed, and estimated time to reach zero BAC. Includes FAQ covering calculator accuracy, standard drink definitions by country, body weight effects on BAC, and BAC zone meanings.

### Elimination Timeline
URL: /tools/time-to-sober
Free, no account required. Enter how many standard drinks you've had to see a projected timeline showing when your BAC will reach the legal driving limit and zero. Based on the average alcohol elimination rate of 0.15‰ per hour. Displays: estimated peak BAC, time to full sobriety, and key sobriety milestones visualized across impaired, caution, and sober zones. Includes FAQ on whether you can sober up faster, morning-after driving safety, acute tolerance (feeling sober vs. being sober), and how body weight affects elimination speed.

### Drink Pacing Calculator
URL: /tools/drink-pacing
Free, no account required. Set a target maximum BAC (e.g. 0.5‰), your body details (gender, weight), preferred drink type, and session duration to calculate how many drinks you can have and the recommended time gap between each drink. Displays a projected BAC curve showing how your BAC will rise and fall over the session, plus a drink-by-drink pacing timeline. Includes FAQ on safe drinking pace, how food affects alcohol absorption, body weight and drinking pace, and impairment thresholds by country (Sweden 0.2‰, Europe 0.5‰, US/UK 0.8‰).

### BAC Simulator
Experiment with different drinking scenarios to understand how drink count, spacing, and body parameters affect BAC curves.

## Technical Details

### BAC Calculation
- Uses the Widmark formula: BAC = (alcohol in grams) / (body weight × r-factor) − (burn rate × hours)
- Gender-specific r-factors (male: ~0.68, female: ~0.55)
- Configurable burn rate presets: Very Slow (0.10‰/h) to Very Fast (0.20‰/h)
- 30-minute absorption window with 10% instant absorption
- BAC calibration feature for personalized accuracy using breathalyzer readings

### Standard Drink Definitions
- Sweden: 12g per unit
- UK: 8g per unit
- USA: 14g per unit
- Canada: 13.6g per unit
- Australia: 10g per unit
- Denmark: 12g per unit
- France: 10g per unit

### Hangover Risk Algorithm
Weighted scoring based on: alcohol amount (35%), peak BAC (23%), time above thresholds (14%), drink mixing (10%), high-ABV beverages (10%), drinking pace (8%). Hydration can reduce risk by up to 20%.

## Frequently Asked Questions

**Q: Is AlcoInsights a medical device?**
A: No. AlcoInsights provides estimates based on the Widmark formula and should never be used as a substitute for actual BAC measurement or medical advice.

**Q: How accurate is the BAC estimation?**
A: The Widmark formula provides a reasonable estimate, but individual metabolism varies. The BAC calibration feature (Pro) lets users refine accuracy using breathalyzer readings.

**Q: Can I use AlcoInsights to determine if I'm safe to drive?**
A: AlcoInsights provides estimates only. Always err on the side of caution and never rely solely on any app to determine driving fitness.

A: Yes. All data is stored securely with row-level security. No data is shared with third parties. See our privacy policy at /privacy.

**Q: What platforms does AlcoInsights support?**
A: AlcoInsights is a PWA that works on any modern browser. It can be installed on iOS, Android, and desktop for a native-like experience.

**Q: Is the Learning Hub free?**
A: Yes. All articles, videos, and interactive tools in the Learning Hub are free and accessible without an account.
