Health: This is what will really help you strengthen your immune system
Coronavirus: What is the real probability that my child will get Covid-19 at school?
Although they seem a thing of the past, the chilblains are back and even in the smallest.
Ventilation is non-negotiable, but it is clear that nobody wants to be cold.
How can we get it?
What is the best way to keep warm without ending up looking like a "Michelin doll"?
The three-layer theory
We tend to bundle up with endless
layers in onion mode
when, in reality, there are more comfortable and efficient ways to do it.
The three-layer theory, which is widely accepted by people who spend time in the mountains for various reasons, proposes:
First layer:
The first layer seeks a "
second skin
" effect and we will achieve this thanks to a thermal undershirt.
No matter how much affection you have for them,
forget about the advertising t-shirts with pellets
, the one from that trip through Ecuador or the one they gave you in the popular race of the festivities of your town.
Cotton absorbs moisture and in this case what we want is the opposite: to keep the moisture from the sweat as far away as possible from the body, evacuating it to the second layer.
How do we choose a good thermal shirt?
As almost always, looking at the label.
In its composition there must be materials such as polyester or, for example,
blends of polyester with polyamide
.
Many shirts also include
elastane
in their composition so that they fit better, achieving that sought after "
second skin
" effect.
Second layer:
The function of the second layer is that of insulation and in this case a good choice may be the useful polar linings.
Important!
In addition to the classic synthetic materials that we have discussed, let's not forget that merino wool is an excellent option, and also sustainable, for this type of outerwear.
Let no one think of a thick "itchy" wool sweater!
Merino wool garments are "not itchy" as they have very fine fibers.
Third layer:
A fiber or feather jacket can be a good option.
Let us remember that if we are going to use them indoors while we work, we write ... it is advisable that they
be light
as much as possible
to allow movement in the arms
.
The "anticovid" poncho and other teasing
Precisely to facilitate movement in the arms,
there are
currently
numerous companies proposing ponchos or "school blankets" as a solution
so that children can comfortably carry out their tasks in class while keeping the windows open.
A poncho can, of course, be a good coat option, but let's not forget that a poncho is just that: a poncho.
There is no evidence that "covid blankets" or "covid ponchos" decrease transmission of the virus.
On the contrary, they
can lead to a false sense of security thinking that the child is "more protected" by relaxing other measures.
Let us remember that a mask, distance, hand washing and ventilation are still the essential measures and that "anticovid fabrics or surfaces" do not fall within the recommendations of any health authority.
Shoes: return of the chilblain
Filomena brought snowmen into our lives, but also chilblains, old men forgotten in many families who, however, never quite left.
During these days, photos have been shared on social networks of some children's limbs with chilblains due, in many cases, to the use of inappropriate footwear for snow.
In
snowy and rainy
areas,
remember that footwear with good insulation on the sole and studded
to avoid slipping is essential.
The classic "goretex" is still a good choice as a waterproof technology.
And of course, let's not forget that "
second skin
" on the feet that are socks.
In this case
, merino wool socks are also an excellent option.
Heat patches
There is a type of heat patches - which adhere to tissue and not to the skin like patches that apply heat for a therapeutic purpose - that can be useful in some contexts.
How do they work?
After previously shaking them, thanks to
a thermal reaction
that can be similar to that of "self-
heating
" coffees, they reach temperatures of up to 50 degrees with a duration of between five and ten hours.
As I mentioned, they
must adhere to the fabrics
, for example, between the first and second layers or between the sock and the boot.
They are not recommended for use in young children
, but they can be a complement for adolescents and also for many adults who work outdoors.
CO2 meters: when in all schools?
The most effective strategy for renewing the air in classrooms and reducing aerosol transmission is to ventilate naturally,
introducing "fresh air" from outside into the building
.
When a building is occupied, the CO2 concentrations inside are elevated by the CO2 exhaled by the people who occupy it.
It is true that a high concentration of CO2 in a classroom or an office does not necessarily imply the existence of "viruses floating in the air" in the form of aerosols (no occupants may be infected).
But given the impossibility of knowing it, this data can serve as a good guide to know if the rooms are being adequately ventilated.
For all this, it
is highly recommended to have a CO2 meter
.
The usual outdoor CO2 concentration (outdoors) is around 420 ppm and it is recommended that it not exceed 700 ppm indoors.
The myth: we don't "get cold"
There is an ingrained belief that we can catch a cold or the flu because "
we have caught the cold
."
We know, and today more than ever, that for an infection to occur,
the presence of the "bug" that originates it (virus, bacteria ...) is necessary
.
Therefore, without the existence of viruses, cold alone will never be the ultimate cause of a cold or flu.
However, it is true that the cold can contribute in some way to making the "bugs" find their way easier.
How?
In our nasal mucosa we have a kind of villi, called cilia, that act like a broom "sweeping" the agents of evil that try to sneak in and do their thing in our body.
The cold can make this "internal broom" of our mucous membranes not work
as it should, favoring infection.
Covering our airways, for example, with a scarf or scarf can be a good option
to minimize this undesirable effect of the cold.
This year,
thanks to the mask our "internal broom" is a bit more protected as standard
.
Something good had to have.
