Your Brain and nervous system actually work different that those of someone who is not highly sensitive. You’re more aware of the environment around you, and because you notice more, you can become more easily overwhelmed. Busy environments or more intense sensory stimuli, like load noises , high-pressure situations, or chaotic scenes make you stressed.
You tend to be cautious, preferring to look before you leap. You’re probably more conscientious and have high levels of empathy. You reflect more and can concentrate deeply, especially when there are not distractions. You’re deep and thoughtful.
