I read some Yogi can sleep naked at snow. Is there any scientific studies how they did it? Also what exactly regulate our body temperature? How much is the role of ATP in it?
There is no scientific study showing how they do it because they can't.seazal said:I read some Yogi can sleep naked at snow. Is there any scientific studies how they did it?
I read that the indigenous peoples of Tierra del Fuego, maybe the Yamana people, who did not wear clothes, would roll their baby in the snow to warm them up. I am sure you will have experienced the rush of blood to the periphery when eventually you remove your hands from the snow.seazal said:I read some Yogi can sleep naked at snow.

The set point temperature, Tset, is determined by a reference signal that is the constant FR of the temperature-insensitive neurons (I) (Figure 1.5) while the effector neurons receiving antagonistic excitatory and inhibitory signals from W and I function as an “error-comparator” for generating their adaptive neural output. The cold-sensitive neuron (C) is not cold-sensitive per se, but it is the inhibitory input from the warm-sensitive neuron (W) that provides it with cold-sensitivity. The thermosensitive neurons of POA also receive information on the body temperature from the spinal cord, via the brain stem. The set point temperature, Tset for effector neurons (w and c), is the temperature at which the excitatory and inhibitory inputs are balanced, and any change in the FR of W and I neurons will cause a shift in the Tset; when the FR increases, the Tset will be higher, and the contrary will happen when the FR decreases. Several internal and external stimuli that increase the FR of W and C neurons are known to lead to corresponding elevations of the Tset.
So , I don't think anyone actually answered your question. The mechanism of thermogenesis is associated with mitochondria. In the oxidative phosphorylation system, the electron flow from an oxidised NADH through complexes I-V to generate ATP is coupled to proton pumping from across the intermembrane space. These protons enter through complex V to generate your ATP. This mechanism also produces your mitochondrial membrane potential However some protons instead enter through the uncoupled proteins UPR at the mitochondrial membrane and the free energy released is heat. This produces your body temperature. So its the fact these protons don't go into making any ATP that makes body temperature. From this, metabolism and mitochondrial bioenergetics is linked to body temperature and mechanisms which control metabolism regulate body temperature. Its all interconnected.seazal said:I read some Yogi can sleep naked at snow. Is there any scientific studies how they did it? Also what exactly regulate our body temperature?

The main source of body heat is metabolism, which is the process of converting food into energy. This process generates heat as a byproduct, and is responsible for about 70-85% of the body's heat production.
The body has a built-in mechanism called thermoregulation to maintain a stable internal temperature. This involves the hypothalamus in the brain sending signals to adjust the body's heat production and loss through actions such as shivering, sweating, and changes in blood flow.
Yes, external factors such as the environment, physical activity, and clothing can impact the body's heat production and regulation. For example, being in a hot environment can cause the body to produce more sweat to cool down, while exercising can increase heat production through muscle activity.
As we age, our body's ability to produce and regulate heat declines. This is due to a decrease in muscle mass and a slower metabolic rate. Older adults are more sensitive to extreme temperatures and may have a harder time maintaining a stable body temperature.
Certain medical conditions, such as hypothyroidism and diabetes, can affect the body's metabolism and therefore impact heat production and regulation. Additionally, substances like alcohol and certain medications can interfere with the body's ability to thermoregulate.
