🧠 Why Sleep Is Crucial for the Brain
During deep sleep, your brain activates the glymphatic system — a cleaning process that removes toxic waste, including proteins linked to Alzheimer’s disease. No sleep = no cleanup.
🚨 What Happens If You Don’t Sleep Enough?
- Poor memory and focus
- Mood swings and anxiety
- Weakened immune system
- Increased risk of heart disease and obesity
Even one bad night affects your thinking like alcohol does.
🕐 How Much Sleep Do You Need?
Adults: 7–9 hours per night
Teens: 8–10 hours
Quality matters too — irregular schedules, screen time, or caffeine can disrupt your sleep cycle.
✅ Science-Backed Tips for Better Sleep
- Sleep and wake at the same time daily
- Avoid screens before bed
- Keep your room cool and dark
- No caffeine after 2 PM
- Wind down with reading or meditation
Final Thought: Sleep isn’t a luxury — it’s essential. Want better focus, mood, and memory? Start by getting a full night’s sleep
