Central nervous system stimulants, such as caffeine and amphetamines, are known for their ability to increase alertness, attention, and energy levels. They work by stimulating the central nervous system, which includes the brain and spinal cord. This stimulation can also lead to an increase in body temperature. Therefore, it is incorrect to say that central nervous system stimulants cause a decrease in body temperature or heart rate. Additionally, some people may experience a sense of calmness after consuming stimulants, but this is typically followed by the stimulating effects. Therefore, the calming effect cannot be considered a direct effect of central nervous system stimulants.
