We all know caffeine gives us that extra boost. Whether it's the morning coffee that jump-starts our day or the energy drink that powers us through a late-night study session, caffeine is a beloved stimulant. But how much caffeine is too much, and how does it really affect our sleep?

Caffeine Content: A Quick Look

• Coffee: A cup of brewed coffee typically contains 95-200 milligrams (mg) of caffeine, with espresso packing a stronger punch at around 64 mg per shot.
• Tea: Black tea generally has around 47 mg of caffeine per 8-ounce serving, while green tea contains slightly less at about 28 mg.
• Energy Drinks: This is where things can get tricky. Energy drinks vary wildly in caffeine content, with some containing upwards of 300 mg per can.

Popular Energy Drinks and Their Caffeine Content (Approximate):

• Red Bull: 80 mg
• Monster Energy: 160 mg
• Rockstar: 160 mg
• 5-Hour Energy: 200 mg

The Sleep-Stealing Effect

A recent study shed light on how caffeine can disrupt our sleep, even when consumed hours before bed.

• Small Doses: A small cup of coffee (around 100mg of caffeine) is usually okay.
• Big Doses: Consuming 400mg of caffeine or more (roughly equivalent to 4 cups of coffee or 2 energy drinks) can significantly disrupt sleep for up to 12 hours.

How Caffeine Disrupts Sleep:

• Reduced Deep Sleep: Caffeine interferes with deep sleep, the restorative phase crucial for feeling refreshed.
• Increased Wakefulness: It can lead to more frequent awakenings throughout the night.
• Difficulty Falling Asleep: You may find it harder to fall asleep after consuming large amounts of caffeine.

How Caffeine Can Sneak Up On You:

The most concerning part? You might not even realize how much caffeine is affecting your sleep. The study found that people often underestimate the impact of caffeine, especially when consumed earlier in the day.

Tips for Caffeine Consumers:

• Be Mindful of Your Intake: Track your caffeine consumption throughout the day.
• Limit Afternoon and Evening Caffeine: Avoid coffee, tea, and energy drinks in the afternoon and evening.
• Listen to Your Body: Pay attention to how caffeine makes you feel. If you notice difficulty sleeping, cut back.
