Is a rapid heartbeat in hot weather dangerous? When should medical evaluation be sought?

A rapid heartbeat in hot weather may be a normal physiological response as the body increases blood flow to the skin to dissipate heat. This often occurs after sun exposure, outdoor physical activity, heavy sweating, or prolonged exposure to hot, humid, and poorly ventilated environments.
However, a rapid heartbeat may also be a sign of dehydration, low blood pressure, electrolyte imbalance, or cardiovascular disease, especially if it is accompanied by prolonged palpitations, chest pain, shortness of breath, dizziness, fainting, or a sensation of an irregular heartbeat.
