Hypothetically, if the threshold is normally -60mV, but now we have too much calcium on board, our threshold is now -50mv. That is a difference of 40mV that the cell has to account for in order to depolarize. In skeletal muscle, this can cause weakness, fatigue, etc. Too little calcium will cause the threshold to become more negative (gets closer to the resting membrane potential).
OK, this is probably going to come with you laughing at me... Once in a while I wake up with the back of my head sweating, and it`s more common when I take a nap during the day.
This will cause the metabolic rate to increase and increase the likelihood of night sweats. * Avoid spicy food â especially in the hours preceding bed time. * Activities such as yoga or meditation can be helpful before going to bed. * It is important that people ensure that their room is not overheated.
