We all do it. But what if your daily bathroom routine could pose serious health risks—even death? According to anatomy professor Michelle Spear from the University of Bristol, a common habit known as the Valsalva manoeuvre could be more dangerous than most people realize.
The Valsalva manoeuvre happens when you hold your breath and strain while trying to “push” during a bowel movement. This action increases pressure in the chest and activates the vagus nerve, which helps regulate your heart rate. While mostly harmless for healthy people, Spear warns it can trigger dangerously low heart rates, fainting (defecation syncope), or even cardiac arrest, especially in those with underlying heart conditions.
This is believed to be what contributed to Elvis Presley’s death, as he was reportedly straining in the bathroom with chronic constipation and a weakened heart.
And that’s not the only bathroom hazard. Spear points out that sitting too long—especially while scrolling your phone—can increase the risk of hemorrhoids and anal fissures. The Western-style toilet also doesn’t help. Unlike squatting toilets, our typical sitting posture causes the rectum to bend, making it harder to pass stool and encouraging straining.
Even your smartphone could be part of the problem. Studies show that phones taken into bathrooms are often contaminated with bacteria from fecal matter, sometimes housing more germs than the toilet seat itself.
So, what can you do?
- Don’t strain—breathe normally and relax.
- Limit time on the toilet (leave your phone outside).
- Improve posture with a footstool or toilet squat aid.
- Eat more fiber and stay hydrated to keep things moving naturally.
When nature calls, answer wisely—your heart, gut, and overall health will thank you.
