Why You Still Feel Tired After 8 Hours of Sleep

🌙 3. Why You Still Feel Tired After 8 Hours of Sleep — The Hidden Science

 8 hours isn’t always enough. Learn the real science behind restorative sleep and how to finally wake up refreshed.

😩 When “Enough Sleep” Isn’t Enough

We’ve all been there — 8 hours of rest, yet you wake up groggy. The culprit? Poor sleep quality. The number of hours you sleep is less important than how restorative those hours are.

🧠 Sleep Quality vs. Quantity

Research shows that deep and REM sleep phases matter more than total duration. If your body keeps shifting positions, or you’re too hot, you might never reach those critical stages.

🔬 Common Disruptors

• Incorrect mattress firmness causing micro-awakenings

• Poor temperature control leading to sweat or chills

• Stress and irregular routines disrupting circadian rhythm

🌿 How to Improve Sleep Quality

• Choose a mattress with pressure relief and airflow

• Keep your room between 18–20°C

• Follow a consistent bedtime routine

• Reduce caffeine and screen time before bed
