Water Before Bed: Not a Heart Attack or Stroke Prevention Method, Experts Say
Confirmed
In Short: A Quora question about whether drinking water before bed prevents heart attacks or strokes has been answered by a cardiovascular surgeon, who explains that while hydration is important, it does not offer specific protection against these conditions.
A Quora user recently inquired whether drinking a glass of water before bed reduces the risk of a heart attack or stroke. According to a cardiovascular and thoracic surgeon from Gleneagles Hospitals, Parel, the answer is not as straightforward as simply drinking water before sleeping.
The surgeon explained that while water helps maintain normal blood volume and circulation, it does not provide additional protection against heart attacks or strokes for most healthy individuals. Mild overnight dehydration is unlikely to independently trigger these conditions.
However, severe dehydration can reduce blood volume and make the blood more concentrated, which may affect circulation and increase clotting risk, particularly in vulnerable individuals. Therefore, while staying hydrated is important, it is not a specific preventive measure for heart attacks or strokes.
Artificial intelligence algorithms are also being developed to help identify heart conditions early, but they do not address the specific claim about water consumption before bed.
The Indian Express reports that water before bed is often recommended as a simple way to stay hydrated overnight, but it does not independently protect the heart or reduce stroke risk.
What's confirmed
- A Quora user recently inquired whether drinking a glass of water before bed reduces the risk of a heart attack or stroke. According to a cardiovascular and thoracic surgeon from Gleneagles Hospitals, Parel, the answer is not as straightforward as simply drinking water before sleeping.

What's still developing
- By analyzing an electrocardiogram, a common 10-second test of the heart’s activity, AI has been cleared to screen for common arrhythmias and structural heart conditions, and algorithms in development aim to pinpoint patients at highest risk of sudden cardiac arrest.
- The most severe kind of heart attack occurs when a coronary artery, which supplies blood to the heart, is completely blocked off.
- While many of those models are focused on early diagnosis and prevention, AI also might help a patient when they’re having a heart attack.
- Those patients need to get to a cardiac catheterization lab as soon as possible to open up the blockage and restore oxygen to the heart.
- On an EKG, doctors can identify these kinds of myocardial infarctions from their characteristic “ST-segment elevations.” To read the rest of this story subscribe to STAT+.
- So, if you’re thirsty before bed, there is nothing wrong with having some water.
- The answer, as it turns out, isn’t quite as simple as “drink a glass of water before bed and protect your heart.” DISCLAIMER: This article is based on information from the public domain and/or the experts we spoke to.
- But that doesn’t mean drinking more water at a particular time offers extra protection.
