High rate of heart attacks and cardiac arrests in the bathro
Many people want to prioritise heart health, but have limited knowledge about the signs and symptoms that indicate an unhealthy heart. Most people spend an average 30 minutes or 2 per cent of their time per day in the toilet.

But, it seems to be the place where heart attack and cardiac arrests happen at a disproportionately-high frequency, of 8 to 11 per cent. Since bathrooms are private places, detection and resuscitation are always delayed, and outcomes are, therefore, poor. The frequency of collapse is 8 per cent, and the chances of revival a dismal 13 per cent.

The most common cause of heart attack and sudden cardiac death in the toilet is a consequence of defecation/micturition syncope. There is a decrease in blood pressure during straining because of an imbalance between the sympathetic and parasympathetic autonomic nervous system; this leads to a decrease in blood flow to the brain and loss of consciousness. These events may also lead to a sudden surge in blood pressure, heart attacks, and sudden cardiac arrest in the toilet and bathroom. The other causes may be rushing to the toilet after feeling sick, nausea/vomiting, and collapsing.

Taking a shower — either too cold or too hot — can impact heart rate, blood pressure, and distribution of blood flow. Taking a bath in water that is too cold can lead to blood flow from all sides towards the head, increasing the stress on arteries and capillaries, which may cause cardiac events.
