There is no sure way to prevent the hot and cold cycle, but there are some things you can do to try to minimize it. One is to keep your house as evenly warm as possible, so that there are no drastic temperature changes that could trigger the cycle. Another is to avoid activities that would cause you to sweat excessively, as this can also lead to the cycle. Finally, if you do experience the cycle, try to treat the symptoms as quickly as possible so that they do not worsen.
