Cold water, an ally to lose fat?
According to a study published on PubMed, “cold showers might lead to a change in weight or fat distribution in the body. The cold will mobilize the brown fat and melt it in a few minutes (source 1)”. And this brown fat or brown adipose tissue is precisely the one that we might well want to eliminate, being located mainly at the top abdomen and neck. Another clinical study from Quebec and Sherbrooke completes: “brown fat in humans can burn a significant amount of energy already stored in other fats when the body is exposed to cold” (source 2). And who says “burn energy says” burn calories “….In In this sense, we might therefore say that a good cold shower contributes to weight loss.
How many calories do you burn when you take a cold shower?
While some health professionals such as Doctor Frédéric Saldmann believe that a cold shower at 20°C would allow you to lose on average between 100 to 200 calories in two to three minutes, this amount of energy is still rather low if it is taken compared to any form of physical activity. One hour of jogging (10 km/h) will, for example, burn between 700 and 900 calories and around 400 calories for one hour of basketball (source 3).

Are there any health risks in taking a shower with cold or even icy water?
Although cold showers have many health benefits, they can also carry some risks. In fact, according to the Montreal Heart Institute, cold can be associated with an increase in cardiac symptoms (angina, arrhythmias) and an increased incidence of myocardial infarction and sudden cardiac death. “Even in healthy volunteers, the simple act of dipping the hand into cold water while holding the breath can cause cardiac arrhythmias (nodal and supraventricular tachycardias) (source 4). In addition, it will be important not to do not take a cold shower immediately following prolonged exposure to heat, at the risk of causing thermal shock.It will also be essential not to stay too long in the cold shower as this can cause hypothermia….But rest assured you will realize it long before if it happens.
Finally, if you have any pre-existing health conditions, it will be recommended to consult a doctor before starting to shower with cold water.
