Cold – everything to the head: what’s wrong with hot yoga
Hot yoga (or bikram yoga) – the direction of classical yoga, which has not been losing popularity for several years. This happens, first of all, because we are all absolutely sure: if we make well-known asanas in a clearly hot place, then the fat in the body will be burned faster , which means it will be easier to lose weight. But is it really so? It turns out, just not. Recently, scientists have found that training in the cold work to get rid of excess kilos much better.
A new study at the University of Tokyo claims that replacing weekly hot yoga with a weekly session in a cool pool will affect your weight more clearly. The fact is that exposure to low temperatures for long periods of time obviously improves the body’s ability to regulate blood sugar and increases metabolism.
This effect, scientists explain, is the result of stress, which is promoted by the influence of cold temperatures on the normal body temperature. In the end, fat begins to turn into energy to produce the necessary heat.
It is worth noting that the fitness community has long been discussing the topic of ideal temperature for training. There are many “hot” workouts that increase the amount of sweat and are supposed to facilitate weight loss. At the same time, Olympic swimmer Michael Phelps, for example, is sure that the cool environment automatically causes the body to work more intensively and, as a result, quickly removes it from excess fat.
The Japanese study, according to the Daily Mail, has deepened the properties of various types of fat to answer the question of what temperature is better in fact.
Recall that there are two main types of fat: brown and white. Brown fat is mainly found in newborns that use it to regulate body temperature before developing the ability to tremble. This fat is responsible for burning calories for the purpose of generating heat and is not associated with health risks.
In adulthood, most of the brown fat is replaced with white, which isolates and softens the organs. Historically, the body stores white fat to help people survive at low temperatures and use it as an energy source when food is scarce. However, today our bodies store white fat even though the food is easily accessible.
In their study, scientists from Tokyo discovered a third type of fat, which was called beige fat. Like brown fat, it is designed to destroy fatty tissue and sugar, improving sensitivity to insulin and activating metabolic processes .
Experiments have shown that after just one week in a room with a temperature of 0 degrees Celsius, the protein in laboratory mice changed, turning useless white cells into thermogenic beige cells. The team is sure that the same effect with further study will be achieved without the cold. How exactly – this question is still open.
“Understanding how the environment affects metabolism is interesting from a scientific, medical and pharmacological point of view,” said lead author Yuro Sakai. “Our subsequent work, we think, will allow us to look more closely at epigenetic modifications of thermogenesis, so that in the future we could manipulate it.”
