Your heart is self-regulating, but beware of the psychological, environmental, and physiological factors that can affect your beats per minute. For example, if you are tired, on medication, under stress, at a high altitude, or in high humidity, your heart rate may change. Also, blood sugar levels, different foods, lack of sleep, anxiety, fear, or anger can alter your heart rate. When you tie your training shoes, your heart rate increases. Just anticipating a workout can measurably boost your heart rate!
