As every Thursday we bring you a new chapter of The health of the adventurer. This section is signed by the people of Activa Mente, health exercise specialists. Today we will talk about a fairly familiar topic, especially if you practice hiking.

Rubbing, blistering and harshness

Now that summer arrives, the heat, the sweat, the days of vacations, the beach or the mountain, we will take advantage to comment on some subjects related to this time of the year.

Today we will continue to address the issue of feet But focusing on specific problems that are favored by several factors (sweat, footwear that directly contacts the skin, more free time to do more activity, etc.).

In this case, we will focus on the outermost part of the foot (skin) and the problems that could arise related to physical activity and loads representing support, contact with the ground and its continued use for moving.

The skin has a function of protection and communication (for all the nerve endings it contains), and differentiate three superimposed layers from more superficial to deep called epidermis, dermis and hypodermis.

The epidermis, being the most external, is the one that is most exposed and represents the first barrier of protection. In this case we are interested in its function and reaction to the different mechanical stimuli, namely the friction maintained with another surface together with the pressure. It is in this layer that we notice the dreaded scrapes, wounds, blisters and harshness. These can be produced for different reasons, taking into account that our foot and footwear do not form a compact unit.

The difference that a lesion or other on the skin is produced has to do much with the stimulus or the area in which it occurs. In this sense, for example, the hardness or callosities are adaptations of that area of ??the skin to a constant stimulus of pressure plus friction. Why it is possible to produce a blister or wound can be due to:

-                Friction with some more sharp or protruding area

-                Moisture of the foot that makes the skin softer

-                Greater movement of the usual inside the shoe for not having an adequate size

To give you a clearer idea of the problems that could arise and their possible solutions, we wanted to explain them from these representative cases:

Case 1

Situation: Person who premieres summer shoes (sandals) and you get scrapers coming to produce wounds or blisters.

Explanation: The difference between summer footwear and other footwear is that we wear them without socks (except in some countries) and the skin is much more exposed to the rubbing of the different materials of the sandal.

Advice: It is important to take into account a shoe made of moldable material that although at first may be somewhat rigid, over time adapts to the ankle, midfoot and fingers. So, besides trying it and being comfortable with it, you have to walk a little. The moment you notice that the first steps produce annoying friction, you can put something that covers the area of the skin affected by the friction with the aim of preventing a major problem and let the shoe adapts (bandages, Plaster, special dressings for blisters and scrapes, sprays or anti-rubbing substances, etc.). Without naming the brand, tell them that the last two work especially well, and dressings alleviate much when the blister or rub has appeared.

Case 2

Situation: Ampule blisters on the toes of walking for a long time on roads or mountains.

Explanation: The toes should move in unison as we walk or move. The blisters will come out mainly by the friction between them, which means that they are not moving well. In case this happens, it must be taken into account that it could be due to the muscular imbalances of the area (the foot) and how it affects the overload to the different parts of it.

Advise: To prevent it, in this case it is essential that the foot is prepared to make that physical effort, detecting and correcting the imbalances. In case the blisters have already occurred, apart from curing the wound, the socks could be well with fingers, as they isolate each of them and prevent them from coming into direct contact with each other.

Case 3

Situation: Person who always get strokes and blisters on different parts of the feet when making a march, put what is put.

Explanation: There are people with very fine and delicate skin who are predisposed to have more problems than others.

Advise: To harden the skin long before making the physical effort, it is good to start walking barefoot on safe grounds (for house, floor, tatami, …), rubbing or massage with rosemary alcohol, for example.

To prevent rubbing if you have already started walking, you could put two pairs of socks, one first thinner and one over the other a little fatter, spread the foot of Vaseline before placing the sock or apply the substance anti-ampoules or Scratches that we mentioned earlier.

Case 4

Situation: Person who has had an ampoule behind the heel of a foot when starting to use the mountain boots.

Explanation: The fact that it comes in one foot and not in the two being the same footwear, it is a sign that there could be differences between one extremity and the other, which should be taken into account to make a biomechanical assessment, if there is also Some more associated problems (injuries and overloads repeated or that did not just go).

Advise: As we have said before, finding a type of boot that suits us is very important, then use the appropriate socks and, finally, start using it trying to perceive the reactions of the different areas of our foot.

In case it has appeared, it is best to cure it and cover the area of friction with what is indicated in previous paragraphs.
