Think that late-night espresso is harmless? Your brain waves beg to differ. Caffeine consumption has the power to disrupt your natural sleep-wake cycle and to significantly alter your sleep architecture. 

​

• Delays falling asleep by blocking adenosine, the brain’s natural sleep signal

• Reduces total sleep time by up to 45 minutes, even when taken six hours before bed

• Lowers sleep efficiency by increasing the time spent awake after falling asleep

Jittery nerves, jittery wallet? Caffeine consumption has significant quantifiable effects on impulsivity and consumer behavior, particularly in shopping and gambling contexts.

​

• Increases spending by 50% and item purchases by 30% when consumed before shopping

• Increases purchases of non-essential items by 56% 

• Significantly correlated with higher gambling urge scores and impulsive behavior scores ​​​​​​

Suffering from stained teeth? Coffee, tea, and energy drinks can leave a lasting mark on your smile — and not just the kind that fades by lunchtime.

​

• Stains teeth with tannins that bind to enamel, causing yellowing even with one daily cup

• Linked to higher gum disease rates in those drinking 3+ cups daily

• Weakens enamel through acidity, increasing sensitivity and decay risk over time

Anxiety in your cup? Recent research shows that caffeine intake is associated with an elevated risk of anxiety, including in healthy individuals. Caffeine stimulates the central nervous system, causing the body to produce and release adrenaline, which can trigger anxiety or nervousness.

​

• Mimics or exacerbates symptoms of anxiety, including nervousness, restlessness, and a fast heart rate

• Increases anxiety risk even at moderate doses (<400 mg)

• Triggers panic attacks in over 50% of people with panic disorder at higher doses (equivalent to ~5 cups of coffee)

Does your morning coffee kickstart more than just your day? Besides having a mild diuretic effect, caffeine interferes with the absorption and retention of multiple nutrients.

​

• Interferes with iron absorption by up to 80% when consumed with iron-containing foods or supplements

• Increases stomach acidity by 2.3 times compared to water due to stimulating gastric acid secretion

• Stimulates colon motility 23% more than decaf coffee and 60% more than water​

Could your daily brew be stressing out your skin? Excessive caffeine intake can potentially accelerate skin aging and exacerbate various skin concerns.

​​​

• Stimulates cortisol secretion, which can lead to increased oil production and potential acne breakouts

• Dehydrates skin by acting as a diuretic, leading to dryness, dullness, and more pronounced fine lines

• Slows collagen production and may accelerate wrinkles and sagging over time
