The Science of Better Sleep Habits

Introduction

Good sleep is the foundation of every healthy habit. When you sleep well, your energy, mood, appetite, and focus all improve.

This guide will help you build simple, practical sleep routines that actually stick.

Why Sleep Matters

• Energy → Rested people think clearly and stay active
• Recovery → Muscles, brain, and hormones repair overnight
• Metabolism → Sleep supports stable blood sugar and weight balance
• Mood & Stress → Better sleep reduces anxiety and improves motivation

Simple Science Behind Sleep

• Sleep Cycles
  Your body moves through light, deep, and REM sleep every 90 minutes. Each stage plays a key role in recovery.
• Melatonin (Sleep Hormone)
  Darkness increases melatonin. Bright screens at night delay sleep signals.
• Cortisol (Stress Hormone)
  It should be high in the morning and low at night. Evening calm routines help regulate it.

Daily Sleep Habits

1. Keep your sleep and wake time consistent (±60 minutes)
2. Get 5–10 minutes of sunlight after waking
3. Avoid caffeine after early afternoon
4. Eat dinner 2–3 hours before bed
5. Dim lights and reduce screen use 60 minutes before sleep
