The statement has often been made that to take a cold bath when overheated is dangerous just as it would be to drink a large amount of very cold water when overheated. It is said that one should wait until he cools off before taking the cold drink or cold plunge. To a limited extent there is wisdom in this advice, especially as it applies to getting into cold water when overheated and then remaining there until you have cooled off. Such quick cooling is certainly dangerous, just as drinking too much very cold water is dangerous. On the other hand, a short quick cold bath under such circumstances is not dangerous but highly advisable. The danger in such cases lies in remaining in the water until chilled. As a matter of fact, when one is overheated he can thoroughly enjoy the cold water. You will recuperate quickly under such conditions and you can better afford to take a cold bath when very hot than when chilled. Do not attempt cold bathing when you have "goose flesh" or when your hands and feet are cold. Under such circumstances the hand bath is preferable. It is always best when overheated to cool off gradually, and after the bath taken under such circumstances to use a sweater or bath robe or other covering to insure the desired result. When one is overheated, it is best to drink water lukewarm or hot or only moderately cool. If you drink lukewarm water when overheated you can take any quantity desired. As previously stated, however, I would like to point out that if you are carrying out the regimen of hot-water-drinking and exercise previously referred to, a daily cold bath is not at all necessary. It might be taken with benefit if you are vigorous, but by flushing the body with a large amount of liquid according to the plan I have suggested virtually all functions of the body, including that of the skin itself, are accelerated in their activities. Under such circumstances less bathing is required, at least for the purpose of maintaining proper circulation and functional activity. Therefore the question may be left open for each individual to determine. One may take a cold bath or not, just as he may desire, while following the regimen referred to.
