Going to bed should be the safest part of the day. Yet for millions, nighttime has become a silent risk zone for the heart and brain.
The story of Roberto, a 68-year-old man who was active and seemingly healthy, illustrates this perfectly. He died in his sleep—painlessly, without warning. The immediate cause was a massive heart attack, but the real culprit had been silently building for years in his nightly habits.
This is not an isolated case. Repeated mistakes during sleep can quietly raise the risk of heart attacks, strokes, and other cardiovascular events. Here’s what specialists recommend avoiding—and how to protect yourself.
1. Sleeping on Your Back with Sleep Apnea: The Silent Suffocation
Ignoring sleep apnea is one of the most dangerous mistakes, especially when lying on your back.
Warning signs include:
-
Loud snoring
-
Pauses in breathing
-
Gasping during the night
-
Waking up tired
Each pause in breathing triggers a cascade of stress on your body:
-
Blood pressure spikes
-
Adrenaline surges
-
Heart rate accelerates
-
Micro-awakenings disrupt restorative sleep
Sleeping on your back worsens the problem. Gravity pushes the tongue and palate backward, narrowing the airway further and increasing cardiovascular risk.
What to do:
-
Sleep on your side, preferably the left side
-
Use pillows or a barrier behind your back
-
Elevate your head 6–8 inches (15–20 cm)
-
Consult a sleep specialist if you experience snoring or breathing pauses
2. Using Sleeping Pills: A Hidden Danger
Some turn to medication to fall asleep, but certain sleeping pills can worsen nighttime breathing.
Benzodiazepines and hypnotics:
-
Depress the nervous system
-
Prolong breathing pauses
-
Reduce the brain’s ability to respond to low oxygen
For those with sleep apnea or heart issues, this can be deadly. Long-term use is also linked to cognitive decline, dementia, falls, and increased cardiovascular risk.
What to do:
-
Avoid self-medicating
-
Focus on lifestyle changes first
-
Consult a doctor to address underlying insomnia
3. Sleeping in a Too-Warm Room
Deep sleep requires a slight drop in body temperature. A warm bedroom forces your heart to work harder at night, causing:
-
Increased heart rate
-
Light, fragmented sleep
-
Blood pressure spikes
-
Higher risk of arrhythmias
What to do:
-
Keep the bedroom between 16–20°C (61–68°F)
-
Use ventilation, fans, or air conditioning
-
Choose cotton or linen bedding
-
Avoid synthetic fabrics
4. Eating a Late or Heavy Dinner
A heavy meal before bed keeps the body in “active mode,” straining the heart and digestion:
-
Intense nighttime digestion
-
Acid reflux and micro-awakenings
-
Increased blood pressure
-
Extra cardiac workload
What to do:
-
Eat at least 3 hours before bedtime
-
Choose light meals
-
Avoid fried foods, heavy fats, and sugars at night
-
If hungry, opt for something small and easily digestible
5. Chronic Sleep Deprivation
Sleeping less than 6 hours per night is a major, underestimated risk factor for cardiovascular disease. Chronic sleep loss causes:
-
Persistent high blood pressure
-
Inflammation
-
Insulin resistance
-
Increased cortisol
-
Higher risk of heart attack and stroke
What to do:
-
Prioritize 7–9 hours of sleep
-
Keep a regular sleep schedule
-
Create a relaxing bedtime routine
-
Treat sleep as a vital health need, not a luxury
Final Recommendations
-
Sleeping on your side can save lives for those with sleep apnea
-
Question long-term use of sleeping pills
-
A cool bedroom protects your heart
-
Eating an early, light dinner reduces nighttime cardiac strain
-
Prioritize quality sleep—your body repairs itself while you rest
Many heart attacks and strokes don’t happen during the day—they happen silently, while we sleep. But small, consistent changes in nightly habits can dramatically reduce risk.
Getting a good night’s sleep isn’t indulgent—it’s life-saving.
