Chemical effects. Adrenaline and nonadrenaline are released from the adrenal glands. Cardiovascular effects. Heart rate and strength of the heart beat increase, readying the body for action by speeding up blood flow and improving delivery of oxygen to the tissues. Respiratory effects. Speed and depth of breathing increase, which brings oxygen to the tissues and removes waste. This may produce feelings of breathlessness, choking or smothering, or chest pains. Sweat gland effects. Sweating increases, which cools the body and makes the skin slippery. Other physical effects. The pupils widen to let in more light, which may lead to blurred vision or spots in front of the eyes. Salivation decreases, resulting in a dry mouth. Decreased activity in the digestive system may lead to nausea and a heavy feeling in the stomach. Muscles tense in readiness for fight or flight, leading to subjective feelings of tension, aches and pains, and trembling.
