Multiple factors affect a person's normal pulse rate. The heart pumps more blood when the temperature and humidity are high, increasing heart rate by five to 10 beats per minute. Stress and anxiety raise the normal pulse rate as well, and it rises a bit when going from lying or sitting to standing but quickly returns to baseline. Certain heart medications also lower the pulse.
