- Dehydration: We lose water through sweat, and dehydration get the blood thicker. Thicker rakehell cast more press on the heart, create it harder to pump expeditiously and increasing the likelihood of helter-skelter electric signaling.
- Electrolyte Imbalance: When you sweat, you lose sodium and potassium - key electrolyte that keep your nerve's electrical scheme balanced. If those levels drop too low, the nerve musculus can't declaration decently, leave to rhythm disturbances.
- Temperature Extreme: It's not just the sear sun. Sudden transformation from cold to hot, or overheat in a unopen car or sauna, can also emphasize the cardiovascular scheme.
The mechanism is root in physiology: as roue vas widen to cool you down, your rake pressure might drop slenderly, causing the heart to beat fast to repair. That compensatory beating is where the fibrillation often begins.
