Cold showers will also help you shred fat, for two reasons. First off, cold showers cause your body to release a series of hormones that are known for their ability to decrease fat. These hormones are testosterone and leptin. Second, cold showers decrease your core body temperature. This means your body will have to burn some extra calories to increase it back up to homeostasis, and where do you think those calories come from?
Cortisone as an oral drug is another common culprit (e.g. Prednisolone). Cortisone often causes weight gain in the long run, especially at higher doses (e.g. more than 5 mg Prednisolone per day). Unfortunately, cortisone is often an essential medication for those who are prescribed it, but the dose should be adjusted frequently so you don’t take more than you need. Asthma inhalers and other local cortisone treatments, like creams or nose sprays, hardly affect weight.
