How to Improve Sleep Quality: 5 Science-Backed Tips

Struggling with restless nights? You’re not alone. Poor sleep affects mood, productivity, and even long-term health. Here’s how to hack your way to better rest—no nuvoradream gimmicks, just evidence-based fixes.

1. Master Your Light Exposure

Your body’s internal clock loves consistency:

• Morning: Get 10+ minutes of sunlight within 1 hour of waking.
• Evening: Dim lights 2 hours before bed. Try amber bulbs.
• Pro tip: Avoid overhead lights after sunset—use table lamps instead.

2. The 20-Minute Rule

Can’t fall asleep? Get up. Lying awake trains your brain to associate bed with frustration.

“Do something boring until drowsy, like folding laundry or reading printed material.” — Sleep researcher Dr. Ellie Keller

3. Temperature Matters More Than You Think

Ideal sleep happens at 18–19°C. Try this:

• Take a warm bath 1–2 hours before bed (the body’s cooldown triggers sleepiness).
• Use breathable cotton sheets.
• Keep socks handy—cold feet disrupt sleep.

4. Caffeine’s Sneaky Half-Life

That 3 pm coffee? It’s still 25% in your system at 9 pm. Cutoff time: 2 pm for most people.

Exception: Fast metabolizers (check your gene test).

5. The Wind-Down Ritual

Replace scrolling with these 20-minute pre-bed activities:

• Gentle stretching
• Journaling (dump tomorrow’s worries on paper)
• Listening to audiobooks at 0.8x speed

Consistency beats perfection. Start with one tip tonight—your future well-rested self will thank you.
