It is a strange phenomenon that some of us are still freezing, while others are absolutely boiling water.

You might be shaking in five layers, exactly the same time your partner is throwing open windows, fanning.

It is not enough for your weight and height, but also their age, sex, diet, sleep habits, lifestyle and even your happiness.

Humans are warm-blooded, with our average body temperature of around 37 ° C.

In warm blood, it just means that we can adjust our internal body temperature regardless of the environment, while the cold-blooded animals are subject to the temperature of their environment.

But as all human beings are "homeothermic" our body temperature can vary greatly, as a fascinating video D News explains.

The temperature control starts in the brain and is controlled by hormones, which reflect the core temperature and the temperature of the outer skin.

The hormone estrogen is part of the regulatory process, according to the Lancet.

Women are generally colder than men, and young people aged cooler. People who are more active tend to have warm hands and feet together than those who do not.

Men tend to have more muscle and more fat women. Operating muscle generates heat during storage of fat cells. Utah State University researchers found that the hands of men were 32.3C on average, while women were 30.7C.

Women's bodies have to work harder to maintain their core body temperature, leaving less energy resources to heat extremes.

The time of the month can come into play as well. The menstrual cycle can change the temperature of a female body in varying degrees.

People tend to feel more hot fat because their central bodies are hot, but its objectives are actually colder.

People with lower body mass index tend to feel colder because the blood pumped through the ends warm up considerably when you return.

We regulate our internal temperature by regulating the heat cells in our skin that detect cold cut our hair and blood vessels in a process called "vasoconstriction" the decrease of blood flow velocity in our.

People who smoke are more vasoconstriction, peripheral coldness, while active people have hands and feet warm.

And it does not only have to be physically warm, it is also our perception of temperature.

If you are surrounded by people that you're comfortable, you will feel warmer. A Canadian study found that people who are alone or feel isolated are more aware of the cold body temperature, while people tend to feel socially connected hot
