The hormone that increases heart rate and blood pressure is noradrenaline.
According to research, noradrenaline, often called the "fight-or-flight" hormone, surges when stress occurs. This surge increases heart rate and blood pressure, which leads to physical symptoms such as a pounding heart, sweaty palms, and rapid, shallow breaths.
- Noradrenaline prepares the body to respond to stress.
- Increased heart rate ensures more oxygen is delivered to muscles.
- Elevated blood pressure helps to facilitate quick reactions.
