Hot weather and heatwaves can affect your blood pressure. The heat can cause blood pressure to drop or temporarily rise, and some people may experience symptoms such as dizziness, feeling faint, headaches or a faster heartbeat.
Staying cool and well hydrated is particularly important if you have high blood pressure, a long-term health condition, or take certain medications.
