Just 6 hours of sleep invites illness — toxins start accumulating in the brain
When you sleep less than 7–8 hours, your brain doesn’t get enough time to perform its “night cleaning” process. During deep sleep, the glymphatic system becomes active — this system removes waste proteins, dead cells and toxins from the brain.
But with only 6 hours of sleep, this system works for a much shorter time. As a result, toxins like beta-amyloid start accumulating, which are linked to memory loss, low concentration, irritability and long-term neurological diseases.
Lack of sleep also weakens immunity, increases inflammation, disturbs hormones and raises the risk of diabetes, obesity, high BP and heart disease. That’s why experts say: sleep less today, fall sick tomorrow.
1. Fix a regular sleep time
Go to bed and wake up at the same time daily. A fixed routine trains your brain to fall asleep faster.
2. Avoid screens 1 hour before bed
Mobile/TV light blocks melatonin (sleep hormone). Keep screens away to fall asleep naturally.
3. Eat light at night
Heavy or late-night meals disturb digestion and delay sleep. Prefer a light dinner 2–3 hours before bedtime.
4. Keep the bedroom cool and dark
A slightly cool, dark, quiet room helps your brain enter deep sleep quicker.
5. Reduce caffeine after evening
Tea, coffee, cola, energy drinks stay in the system for 6–8 hours and disrupt deep sleep.
