Very surely you have had this feeling when you take a pretty cold liquid or eat some ice cream, this happens when the cold touches the nerves located in the upper part of the mouth causing a sudden change in temperature in it, as a reaction of this the Body sends more blood to our head, making the brain feel more pressured and because of that we feel that slight headache.
¿Why are we getting goosebumps?

Surely many have had goose bumps, perhaps by the cold, some caress or whatever the motive, the skin is put so because of muscles under the skin (epidermis) called piloerectores, these muscles are specifically attached to the hair of our body, which is contracted for feel an emotion or feeling and make the hair rise, the main function of this contraction in mammals is to contain warm air between the hairs, Currently this function is considered unnecessary in humans, because thanks to the evolution we have been through, we no longer have a large quantity.

Moles and freckles can come out in all kinds of skin, they appear due to a substance present in our body called melanin. When a group of these substances are gathered in a small part of our body they are considered freckle and lunar.
¿Why are some parts of our body falling asleep?

This occurs when the blood flow in which it travels through us is blocked and you do not let it flow properly. Example when you sleep on your arm, cross your legs, etc. This is called Parestecia. You'll probably wonder why you feel a tingle in that area? Well this is the signal that the brain sends us to change position and thus allow the correct flow of blood.
¿Why are your fingers wrinkled in the water?

When we take some time in the water we see that the fingers wrinkle us, according to what they told us before this happened because our body is covered by an oil called sebum that protects us from the liquids but when we carry a considerable time in the water , the oil that covers the body "disappears" allowing the water to penetrate our skin and causing these to swell,But according to a study published in the journal Biology letters What really happens is that our body narrows the blood vessels by the contraction of their muscular walls and have also concluded that this could have helped our ancestors to improve the Grip of wet or underwater objects.
