What are the signs of an activated nervous system?

When the nervous system is activated, there are several signs that can indicate its state. One of the evident signs is an increase in heart rate, which is caused by the release of stress hormones such as adrenaline and noradrenaline. Elevated blood pressure is another sign, as the activated nervous system constricts blood vessels to redirect blood flow to vital organs. Sweating is also a common symptom, as the body's temperature regulation system becomes more active during heightened nervous system activation. Other indications may include a decrease in salivation, dilated pupils, and rapid breathing. Additionally, heightened alertness, restlessness, and an intensified sense of fear or anxiety are commonly experienced when the nervous system is activated.
