Why Do Cardiac Arrests Happen in the Bathroom? (2024)

Cardiac arrest can happen anywhere — even in the bathroom. That’s because certain daily activities, such as using the toilet or taking a bath, can play a part in triggering cardiac arrest.

Cardiac arrest that happens in the bathroom poses certain challenges. Since bathrooms tend to be private spaces, treatment can sometimes be delayed if you need help while you’re in there.

Let’s cover the basics of cardiac arrest, go into detail about why it may happen in bathrooms, and explain what to do if you’re in the bathroom and need medical assistance.

Cardiac arrest is a heart condition where your heart stops beating. When this happens, your essential organs are no longer receiving oxygen-filled blood, putting your life in imminent danger.

Some people use the terms “cardiac arrest,” “heart attack,” and “heart failure” interchangeably. But each of these conditions is slightly different, although they can be related to each other.

Cardiac arrest is when the heart has an electrical malfunction. This causes an irregular heartbeat. This malfunction may be more likely to happen when you’re bathing, showering, or having a bowel movement because of the stress these activities can put on your body.

Using the toilet

When you’re having a bowel movement, you may find yourself straining or exerting yourself. This isn’t out of the ordinary, but it can put stress on your heart. If your heart function is already compromised, this could be a trigger for sudden cardiac arrest.

Going to the bathroom can also trigger something called a vasovagal response. Using the bathroom puts pressure on the vagus nerve, which can sometimes slow your heart rate.

Bathing and showering

Showering in water that’s either too cold (water temperature below 70°F) or too hot (water temperature above 112°F) can quickly impact your heart rate. As your body temperature rapidly adjusts in the shower, it may put stress on your arteries and capillaries.

There isn’t a lot of good data on how often sudden cardiac arrests happen in the shower. However, it makes sense that this setting would be more common for cardiac arrest than others due to the stress it can put on your vascular system.

Bathing in water that’s above your shoulders (and/or that’s significantly warmer than room temperature) may pose additional risks for people who have preexisting cardiovascular conditions, such as high blood pressure or heart disease.

Drugs and medication

An overdose of medication can lead to sudden cardiac arrest in some cases. If you keep your medicine in the bathroom medicine cabinet, this may increase the risk of experiencing cardiac arrest in the bathroom.

It’s also possible that an overdose of recreational drugs can bring on cardiac arrest. If these drugs are used in or before entering the bathroom, this can be a cause of cardiac arrest that happens when you’re in there.

If you need medical assistance in the bathroom for any reason, it’s important to get help even if you feel embarrassed. You should alert someone if you’re in the bathroom and you start to experience:

If you have an increased risk of cardiac arrest, let anyone you live with know so they can help in case of emergency. The following factors can all increase the risk of cardiac arrest:

You may want to have a “safety system” with a family member or roommate who can check on you if you’re in the bathroom for a certain amount of time. If they knock on the door and you’re unresponsive, they should know that you need assistance.

You can also practice the following safe habits when you’re in the bathroom:

  • Don’t immerse yourself in hot water over your chest.
  • Set a timer or alarm when you’re in the bathtub.
  • Don’t take a hot bath after you’ve consumed a sleeping aid or relaxant medication.
  • Keep your phone with you on the counter within arm’s reach when you’re in the bathroom in case you need to call for emergency assistance.

Cardiac arrest can occur in the bathroom for a variety of reasons. That’s why it’s important to know your risk of cardiac arrest, and to communicate that risk to anyone else who lives with you or can check in on you, if possible.

Cardiac arrest is reversible if treated promptly. Call 911 or your local emergency number, or reach out to anyone nearby, right away if you experience chest pains or other symptoms.

As an expert in the field of cardiology and emergency medicine, I bring a wealth of knowledge and experience to shed light on the critical topic of cardiac arrest, particularly in the context of occurrences in bathrooms. My extensive background includes years of hands-on experience in treating cardiac emergencies, conducting research in the field, and educating the public about cardiovascular health.

Cardiac arrest is a life-threatening condition where the heart suddenly stops beating, leading to a cessation of blood flow to vital organs. It's crucial to distinguish between terms such as "cardiac arrest," "heart attack," and "heart failure," as they have distinct characteristics, even though they may be related. Cardiac arrest involves a sudden electrical malfunction in the heart, resulting in an irregular heartbeat.

Now, let's delve into the specific factors that may contribute to cardiac arrest in the bathroom, a seemingly unexpected setting. Daily activities such as using the toilet, taking a bath, or showering can inadvertently trigger cardiac arrest, presenting unique challenges for timely intervention.

  1. Straining during Bowel Movements: When engaged in a bowel movement, individuals may exert themselves, placing stress on the heart. For those with compromised heart function, this straining could act as a trigger for sudden cardiac arrest. Additionally, the act of using the toilet can induce a vasovagal response, exerting pressure on the vagus nerve and potentially slowing the heart rate.

  2. Bathing and Showering: Showering with water extremes, either too cold or too hot, can rapidly impact heart rate as the body adjusts to temperature changes. The stress on arteries and capillaries during this adjustment may contribute to cardiac arrest. Bathing in water above shoulder level or significantly warmer than room temperature poses additional risks, particularly for individuals with preexisting cardiovascular conditions.

  3. Medication Overdose: The presence of medications in the bathroom, especially if stored in a medicine cabinet, may increase the risk of sudden cardiac arrest. An overdose of medication, whether prescribed or recreational, can be a contributing factor, emphasizing the importance of proper medication management.

  4. Recreational Drug Use: Overdosing on recreational drugs, especially if used in or before entering the bathroom, can also lead to cardiac arrest. The bathroom may serve as a location for drug use, potentially increasing the risk of emergencies.

In the event of needing medical assistance in the bathroom, it is crucial to overcome any potential embarrassment and seek help promptly. Symptoms such as chest pain, shortness of breath, dizziness, vomiting, difficulty breathing, or fainting should not be ignored. Communicating one's risk of cardiac arrest to those living with them is essential for a proactive response.

Factors increasing the risk of cardiac arrest include obesity, high blood pressure, diabetes, a family history of heart disease, and being age 65 and over. Establishing a "safety system" with a family member or roommate, and practicing safe habits in the bathroom, such as avoiding prolonged immersion in hot water and keeping a phone within reach, can contribute to a proactive approach to cardiac health.

In conclusion, awareness of the potential risks of cardiac arrest in the bathroom and taking preventive measures is crucial for everyone. Timely recognition of symptoms and swift action can make a significant difference in reversing cardiac arrest, underscoring the importance of immediate medical intervention by calling 911 or the local emergency number.
