She d.ied in his sleep from doing this: I implore you, don’t do it. It causes heart attacks and strokes.

🚩 5. Sleeping in an Overheated or Poorly Ventilated Room

Why it’s dangerous:
Your core body temperature must drop to initiate deep sleep. An overheated room prevents this, leading to fragmented sleep and elevated nighttime cortisol—a stress hormone that raises blood pressure and blood sugar. Poor air quality (from dust, mold, or VOCs) can also worsen breathing issues.

What to do:

• Keep bedroom temperature between 60–67°F (15–19°C).
• Use an air purifier if you have allergies or live in a polluted area.
• Open a window slightly for fresh air (if safe).

❤️ The Bottom Line

Sleep isn’t passive—it’s when your body repairs your heart, balances hormones, and clears brain toxins. How you sleep matters as much as how long.

“The safest place in the world shouldn’t be a risk zone. Protect your nights—they protect your life.”

If you or a loved one snores, wakes gasping, has unexplained fatigue, or experiences nighttime palpitations, talk to your doctor. Simple changes—or a sleep study—could add years to your life.
