Lightheadedness in the sun: doctors warn of signs that require early medical evaluation.

Lightheadedness when going out in the sun is fairly common during summer, especially among people who stay outdoors for long periods, drink too little water, stand under the sun for too long, or have underlying conditions such as blood pressure disorders, cardiovascular disease, anemia, or diabetes.

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.
