The perception of heat and cold is largely dependent on a person’s everyday habits. In a situation where you are accustomed to living in a cool room, when moving to a warmer apartment, you can experience a kind of shock for the nervous system.
To trust people
It is necessary to warm up, and people will have more confidence. This conclusion was made by scientists from Yale University. Experts conducted an experiment: hot and cold drinks were distributed to volunteers, and after that they offered to assess how credible the peoples are in the photographs . Those of the experiment participants who had to drink hot drinks showed themselves to be more trusting.
It can be concluded: the warmth of the body and the warmth of the soul are connected in our brain much more closely than it is customary to think about it. It turns out that one cup of hot coffee or tea can help to win the trust of a person.
Perhaps this explains the fact that in an expensive store or car dealership, as usual, customers are offered to drink a cup of coffee. Meanwhile, psychologists are ready to give advice: before making an important decision, drink a cold drink.
A recent study by Canadian scientists found a direct link between cold feeling and mood. The more miserable and lonely a person feels, the faster it freezes.
What helps to survive the inhabitants of the Far North ?
Scientists at the University of Cambridge have been able to detect among the representatives of the indigenous peoples of Siberia a positive selection of variants of genes that are associated with survival in cold conditions.
Genetics took DNA samples from two hundred representatives of ten indigenous Siberian ethnic groups. Scientists had to conduct a complex analysis of the distribution of gene variants.
The goal was to find those among them that have become the object of positive selection during the existence of man in Siberia. Scientists have discovered three genes, some of which are selectively presented in Siberians: ENPP7, UCP1, PRKG1.
The second of these genes was previously found during the study of the genetic characteristics of the Teleuts. The protein that is encoded by this gene causes the mitochondria to produce heat.
The ENPP7 gene is associated with fat metabolism. The authors of the hypothesis suggest that it helps residents of the North to cope with animal fatty foods. The PRKG1 gene is associated with a smooth muscle contraction mechanism, whose work is very important for thermoregulation.
What to do to get less cold ?
Scientists have developed tips for those who do not like the cold. We must make new friends, spend our leisure time actively, get enough sleep. Stop smoking and do not give way to melancholy in any case.
So, this was the research to know how cold affects us . Peoples living in the north side are comfortable with cold environment .
