What are the effects of dehydration on heart health?

South Asian Health — Heart & Circulation19 June 2026
Dehydration can have serious effects on heart health. When your body loses more fluids than it takes in, it can lead to an increase in blood viscosity, which can make it harder for the heart to pump blood efficiently. This can put extra strain on the heart and potentially lead to complications such as arrhythmias (irregular heartbeats) or even heart failure. Moreover, dehydration can cause low blood pressure, which can further impact organ function. Staying hydrated is crucial, especially for British South Asians who may be at risk of heart conditions. Drinking enough water and consuming hydrating foods can help maintain heart health and overall wellness.
