💧☀️ Stay Hydrated. Keep Your Heart Happy. ❤️
Summer heat means your body loses more fluid through sweat—and staying hydrated is important for your heart, too.
When you’re dehydrated, your blood volume can decrease, which may make your heart work harder and can contribute to symptoms like dizziness, fatigue, a racing heartbeat, or feeling lightheaded. For some people with heart rhythm conditions, dehydration can also make palpitations more noticeable.
💦 A few simple summer hydration tips:
✔️ Drink water regularly throughout the day—not just when you feel thirsty
✔️ Increase your fluids when you’re exercising or spending time outside
✔️ Keep a water bottle with you
✔️ Limit excessive alcohol and caffeine, which can contribute to dehydration for some people
✔️ If you have been told to restrict your fluids because of a heart condition, follow your provider’s recommendations
❤️ Your heart works hard enough. Give it the hydration it needs this summer!
If you're experiencing new or worsening palpitations, a racing or irregular heartbeat, dizziness, or other concerning symptoms, talk with your healthcare provider.
