A heart attack happens when the heart struggles to pump blood properly. Research suggests that certain habits can trigger an attack, including one that might happen in the shower.
When blood flow to the heart suddenly stops, the heart doesn’t get enough oxygen, though the person may still be conscious and breathing. In some cases, something as simple as a shower could bring on symptoms.
If cardiac arrest happens in the bathroom, getting help can be difficult since it’s a private space, which might delay treatment when it’s needed most.
Cardiac arrest often happens in bathrooms due to a combination of physiological and environmental factors, including:
-
Straining During Bowel Movements – The Valsalva maneuver (straining while holding breath) can trigger a sudden drop in blood pressure, reducing blood flow to the heart and brain, potentially leading to syncope (fainting) or arrhythmias in individuals with heart disease.
-
Sudden Temperature Changes – Bathing, especially with hot water, can cause blood vessel dilation, leading to a drop in blood pressure and reduced oxygen supply to the heart. This can be dangerous for those with underlying heart conditions or low blood pressure. Conversely, cold water can cause a sudden increase in blood pressure, potentially triggering a heart attack or arrhythmia.
-
Slippery Surfaces and Falls – Many cardiac arrests are triggered by falls, which are common in bathrooms due to wet and slippery floors. A fall-related head injury can also contribute to a medical emergency.
-
Autonomic Nervous System Response – Bathing and defecation can activate the parasympathetic nervous system, which may lead to a sudden slowing of the heart rate (bradycardia) in some individuals, increasing the risk of collapse.
-
Privacy and Delayed Response – Since people are alone in bathrooms, a cardiac event may go unnoticed, delaying immediate assistance or CPR, which is crucial for survival.
-
Medication Effects – People with heart conditions often take diuretics or blood pressure medications, which can cause dehydration, electrolyte imbalances, or low blood pressure, increasing the risk of fainting or cardiac arrest.
Preventing Cardiac Arrests in the Bathroom: Measures to Save Lives
For those at risk of cardiac arrest, it’s essential to put preventative measures in place, particularly considering the increased risk associated with bathroom activities. Here are some practical steps you can take to safeguard against this medical emergency:
Avoid straining during bowel movements
When you strain during a bowel movement, your heart rate may drop and the vagus nerve may be stimulated, which could result in a cardiac event. To prevent this, avoid straining by using a stool softener if necessary and including high-fiber foods in your diet to promote regular bowel movements.
Regulate shower temperature
Extremely hot or cold showers can lead to sudden changes in your heart rate and blood pressure, causing undue stress on your heart. It’s advisable to keep the water temperature at a comfortable level to avoid these sudden changes.
Keep emergency numbers handy
In the case of a cardiac event, time is of the essence. Have emergency numbers readily available in an easily accessible location, and ensure all family members know how to dial emergency services.
Learn CPR
In the event of a cardiac emergency, knowing how to conduct cardiopulmonary resuscitation (CPR) can be extremely important. CPR can increase a person’s chances of survival by two or three times, especially if it is done right away. Think about earning your CPR certification and urge your loved ones to follow suit.
Take Extra Precautions If You’re at Risk
Bathrooms can be hazardous areas, especially for those at risk of cardiac arrest. Implementing a safety system that all family members are familiar with can be a lifesaver.
Set up a system where you can immediately alert other family members if you need help in the bathroom. This could be as simple as a bell or more advanced, like an emergency button or intercom.
If you’re at a higher risk for cardiac arrest, let the people you live with know so they can step in if something happens. Give them a heads-up whenever you’re heading to the bathroom so they can stay alert. If you’re in there longer than usual, they should check in. If they knock and don’t get a response, they’ll know it’s time to step in and help.
Try to avoid bathing when you’re home alone, especially if you’re feeling tired. It also helps to check your blood pressure before showering—if it’s too high, it might be best to rest for a bit or even skip the shower.
