This summer, like every summer, you are going to hear about the same health problems, and, like every summer, you are going to understand more or less what we are talking about, but nothing more. Why ? Well, because you’re not doctors, you don’t watch Health Magazine every day or, quite simply, because no one has ever really explained to you what it was all about, all these problems with more or less weird. Lucky you: it’s time to catch up.
Not a single summer goes by without hearing about sunstroke, and honestly we never quite knew what it was about, except that it had to do with taking a little too much sun. in the mouth. Well, sunstroke, in fact, that’s it: overexposure to the sun, which leads to heatstroke. Basically, the body struggles to regulate its heat because of this too violent and too long exposure. This results in sunburn, nausea, dizziness, headaches, or even downright loss of consciousness. The kind of thing that makes you want to wear a bucket hat and curl up under a parasol.
If you have to get wet gradually before entering cool water in summer, it is to avoid hydrocution. Ok, that’s very nice, but it doesn’t tell us exactly what hydrocution is. So we tell you: it’s a heat shock that leads to too rapid a decrease in blood vessels (this is called “vasoconstriction”). It causes vagal discomfort because the heart suddenly slows down to restore normal blood pressure, which means that the brain is no longer properly irrigated. And experiencing vagal discomfort when you’re in the middle of the water is a bit annoying since it leads straight to drowning. Now you have understood it, it is not so much the hydrocution in itself that is dangerous (although the risk of heart attack also exists), but it is above all the fact that it makes us lose consciousness in the water. . In short, do not jump directly into the pool in summer. Instead, listen to mom and dad telling you to get your neck wet first.
Here, let’s stay on topic and explain a bit what actually happens during a drowning. Concretely, therefore, the airways are flooded, which means that there is water where the air is supposed to circulate in the body (in the lungs, suddenly). If it’s soft water, it’ll thin the blood and cause heart fatigue. If it’s salt water, it’ll concentrate the blood and cause pulmonary edema. In both cases, it’s just super dangerous and you have to intervene very quickly by calling the emergency services and applying the right actions if you have undergone first aid training.
Ok, you know, dehydration is the lack of water. We don’t teach you anything here. But we still want to teach you something so we tell you a little more. In addition to the lack of water, what poses a problem in dehydration is the lack of mineral salts, in particular sodium. As sodium helps to fix water in the cells, to make the kidneys, nerves and muscles work, its too strong reduction in the body is dangerous. In terms of symptoms, dehydration first causes thirst, dry lips and fatigue, then, when it intensifies, it goes into fever, headaches, dizziness, malaise, (bad) delirium, coma, and death. (but this means that you are very well dehydrated). You have understood: you have to drink water regularly.
There, you are remembering your beautiful traces of sunburn and you tell yourself that you know what it is, but do you know precisely what is going on in your skin during a blow? of Sun ? No. Or else you’re doing medicine, but what are you doing here then? In short, we speak to those who do not know. Sunburn is a burn caused by UVB rays from the sun. Because of them, there is an expansion of the superficial skin vessels, which causes this characteristic red color. That’s the nice sunburn, in the first degree. Afterwards, there is superficial second-degree sunburn, with blisters but not yet too serious, then deep second-degree sunburn, which destroys the skin vessels and can leave scars. We advise you to wear sunscreen regularly.
Sun exposure doesn’t just cause sunburn. It can also start in melanoma, a malignant tumor of the pigmentary system of the skin. It’s a type of skin cancer. It comes in the form of a dark spot that can have several different shapes. It either comes out of nowhere, or from a mole that we already had, hence the interest of regularly having our skin checked by a dermatologist. If he finds that a task is suspicious, he can remove it and have it analyzed, etc. Once again, the conclusion is the same: put on some good evening sunscreen.
7. Plantar warts
In the summer, you walk barefoot, and you can get plantar warts. Warts are unattractive growths caused by a fairly contagious virus. It spreads either by direct contact (your foot touched that of someone else, bunch of little rascals) or indirect (you walked on the same tiles as this guy who already had a wart). It’s boring but not a big deal since a dermatologist can easily burn his face with liquid nitrogen or acid. Burn the mouth of the wart, eh, not the guy who gave it to you.
8. Plantar mycoses
Let’s stay in the glamor with plantar mycosis (also called “athlete’s foot” if you want to have the impression of being athletic). Plantar mycosis is simply a fungus that has developed on the foot, most often between the toes, where it is very warm and humid. It is usually caught by walking on an infected surface such as in swimming pools or gyms. As for the symptoms, we are on itchy, peeling skin that can smell like death. It’s easily treated with cream or powder, but if you don’t want to get to that, wash your ieps and dry them well.
9. Heavy legs
Among the boring things accentuated by the heat, there are “heavy legs”. In fact, the legs are no heavier than usual, but their owner feels this because his blood circulation is no longer optimal in his little legs. It can even lead to varicose veins, venous thrombosis and phlebitis, which is still less funny than the term “heavy legs”. So not great.
One of the worst things you can get after a swim (or even a plane trip) is a good ear infection from your dead. Otitis is an inflammation or infection of a part of the ear (external auditory canal, middle ear or internal auditory canal, if you are ever familiar with the anatomy of the ear). This results in pain in the ear, a feeling of stuffy ears, and, depending on the case, a liquid discharge. It can be treated very well, but it’s still extremely messy. The kind to fuck you a week’s vacation.
