Why is it cold when a person dies, and why is it colder at home after a person dies

The heat of the human body comes from many aspects, and from its own point of view, it is mainly as follows: 1. The movement of skeletal muscles produces heat. For example, when a person shiveres when they are cold, this is skeletal muscle movement.

2. All cells in the body need to produce heat for work and respiration. 3. Visceral work needs to produce heat, such as the heart beating will produce a lot of heat. 4. The friction between various internal organs also produces heat.

And all of the above is classified as metabolism (except for frictional heat production, which actually only accounts for a small part).

In other words, metabolism is the main cause of heat, and when a person dies, metabolism stops, and at the same time, the internal organs no longer rub, and naturally no longer produce heat, so the body temperature decreases from ice.

Because human body temperature is maintained by the energy released by mitochondria in the body cells for respiration (the energy released by mitochondria has two places, 1 is to maintain body temperature and 2 is to carry out life activities).

The death of a person is also an indication of cell death, if all cells are dead.

Then the mitochondria die, they don't work, and the person's body temperature drops.

When a person dies, there is no breathing, no blood circulation, the human body has no metabolism, so it will not produce energy ATP, and the body's original body temperature is originally released by the metabolic ATP, so when a person dies, there will be no heat.

Physically, entropy is increasing all the time, not decreasing, but because there's no energy uptake, there's no ATP, there's no heat conduction

Death is like a withered lamp.

When the human body dies, all circulatory systems, such as blood circulation, stop functioning, so the body becomes cold. Understand?

Because he stopped eating, he ran out of energy.

No energy**, like a dead thing Of course, it's cool

Because all living things cease to function.

Because his heart won't beat to death.

You can try it and you'll find out.

Mainly because:01. Psychological factors; 02. I did something wrong。That's why I feel scared. Because if that's not the case, then there's no need to be afraid.

01. Psychological factors;

Some people may have watched too many ghost movies, so they always feel that ghosts are very afraid, in fact, from a scientific point of view, ghosts do not exist, so there is no need to be afraid of Ye Qi.

And some people have passed away from their loved ones, and they always frighten themselves, feeling that the house is gloomy, and they always feel as if there is something in the house, so they naturally feel scared.

In fact, it's just their psychological quality, because they have infinite imagination, so they are scared of themselves, and they feel that the house seems to be colder than usual.

02. I did something wrong

Don't do bad things, the night group is slow and half, and you are not afraid of ghosts knocking on the door. So if we don't do anything wrong, naturally there is no need to be afraid, and the other party is still our relatives, how can they do something to hurt us.

Therefore, the reason why this type of person feels that it is very cold in the house is entirely because they may have done something sorry for their deceased relatives, and they always feel that they are in the house, so they will also feel that the temperature in the house seems to have dropped a lot, and it is colder than usual.

ActuallyThere is no inevitable connection between the death of a loved one and whether it is colder in the house. It's just because of the portrayal of ghosts in many movies that gives us an illusion。I feel that after the death of a loved one, it has caused the house to be even colder.

People who think so, on the one hand, are affected by psychological factors, and some people are because they have really done something wrong, so they always feel that their dead relatives are still in this house, causing the temperature in the house to drop. But actually,From a scientific point of view, this is actually caused by self-suggestion.
