our brains are busier than ever before. the nutrients in our brain are literally depleted. this leads to compromises in both cognitive and physical performance. many people have difficulty processing everyday sensory information. any of the senses may be over- or under-sensitive, or both, at different times. these sensory differences can affect behavior, and can have a profound effect on one’s life. responses and reactions to stimuli are bigger than it might be expected. the tendency to become overstimulated cannot be completely avoided. it is impossible to steer clear of all potentially challenging situations – accompanied by the processing of numerous internal and external stimuli.
