Why does my heart rate immediately reach 160 as soon as I start running?
Disease description:
I have recently been feeling that my cardiorespiratory function is not very good. Every time I run, my heart rate immediately reaches 160. May I ask, why does my heart rate immediately reach 160 when I run?

An increase in heart rate is a natural physiological response as the body adapts to increased exercise intensity. When running begins, the muscles' demand for oxygen and nutrients rises sharply. To meet this demand, the heart beats faster, thereby enhancing blood circulation and ensuring adequate supply to the muscles.
Each individual's heart rate response during exercise varies depending on his or her physical condition, age, and overall health status. A person's maximum exercise heart rate can be estimated using the formula (220 - age) × 80%. For some individuals, reaching a heart rate of 160 beats per minute while running may still fall within their safe and effective exercise heart rate range.
There are also many non-physiological factors that can influence heart rate, such as emotional states (e.g., anxiety or excitement), environmental conditions (e.g., high temperature and humidity), and dietary habits (e.g., caffeine consumption), all of which may cause a temporary increase in heart rate.
If the heart rate remains elevated for a prolonged period after exercise and is accompanied by symptoms such as palpitations, chest tightness, or shortness of breath indicating hypoxia, prompt medical attention is recommended.
