People with this condition "have lower-than-normal levels of stress hormones".Cortisol, adrenaline, dopamine and different hormones increment in light of worry of any kind or degree. They keep up your body's ordinary capacities while giving you additional devices to oversee or survive an apparent or genuine danger. On the off chance that pressure waits and your body keeps on feeling debilitated, the hormone levels remain up and some of their defensive activities can make you not feel so well.
