Blue Nails
The colder it gets, it is common for our body to end up reacting in common ways to what it is used to in summer. A common example of this is the presence of blue nails, being able to happen in the hands as well as in the feet and being noticeable with the naked eye.
The reasons why people can have blue nails are different, and can be for mild cases as well as some more complex ones. It is in this way that among the first cases it is worth seeing the presence of poor circulation by the blood, which is also responsible for transporting heat to all parts of the body, this is also the reason why if we cut off circulation in some way, our fingers turn blue and purple.
Another case is the malnutrition, being our body unable to provide the energy necessary to provide body heat in the best possible way.
A somewhat different case is that of the so-called Raynaud's syndrome, which is a blood circulation disorder that causes pain and numbness of the extremities, noting this in that the hands and especially the nails acquire this aforementioned tonality.
