Increase in pulse rate in heat is a completely normal physiological response â when temperatures rise, your blood vessels dilate to release body heat, which slightly drops blood pressure, and your heart compensates by beating faster to maintain circulation. At 115-132 bpm while standing in heat, this is within expected range, but if you feel dizzy, breathless, or your resting pulse at home is consistently above 100 bpm, it warrants investigation.
Next Steps
Stay well hydrated in hot weather, avoid direct sun exposure during peak hours, and rest in cool environments. If you experience palpitations, chest pain, or breathlessness, get an ECG done. Feel free to consult me directly on Practo for a detailed evaluation.
Health Tips
Avoid strenuous outdoor activity in peak heat. If pulse regularly exceeds 140 bpm or you feel faint, see a doctor promptly.
