If someone is easly startled what does that mean and why?

If someone is easily startled, it typically means they have a heightened sensitivity to unexpected stimuli. This can be due to a variety of factors, such as a heightened state of anxiety, a low level of comfort in their environment, or even certain personality traits. Physiologically, it may involve an overactive startle reflex, which triggers a quick reaction to perceived threats. Understanding this response can help in managing environments to reduce unnecessary stress for the individual.
