As combat the heat in pregnancy

Along with the invention of the turbo fan and air conditioning, showers and baths are the best to alleviate the despondency and suffocation caused by high temperatures.

Put under a jet of cold water and other temperate immediately provides welfare, because it cools and activates blood circulation, which in pregnancy is slower. During working hours, women can obtain a benefit similar submerging their arms in cold water and putting wet cloths on the forehead and neck. If hydrotherapy is repeated several times throughout the day, it is possible that blood pressure is stabilized.

In recent months pregnant, it is normal to feel the very heavy legs, and even that will swell a little. The disorder is relieved by sitting a few minutes with the body leaning back and legs elevated.
Rest is very necessary. The pregnant woman should know that the exercise continued, albeit moderate, decreases the blood supply that reaches the fetus as much as 25 percent (depending on the intensity) and that, therefore, it should be pausing for a half hour throughout the day. These periods are ideal for relaxing moments with the exercises learned in the course of maternal education, it should use them.

The clothes more comfortable at this time is that of cotton, linen or silk, all natural fabric. Synthetic fabrics, like the dark colors, warm. A garment with a mixture of both can be tolerated if the percentage of fiber does not exceed 30 percent. The shoes should be wide enough so as not to hinder the movement.

¿Take sun after plucking stain the skin?

Yes, it is because the pigments that give color to the skin are highly activated by the heat of the wax.

If in that state still receive the aggression of ultraviolet rays, the pigmentation will be higher.

How to avoid heat exhaustion

This is a common problem in sport, especially in children and during the summer months. The phenomenon is caused by a drop in blood pressure, loss of body fluids and salts at a faster pace than that of the replenishment.

Also contributing to this situation the impact of heat on blood vessels, which dilate to produce a sudden drop in blood pressure.

By knowing how it occurs, we are able to take some precautions: avoid playing for a long time without replenishing the fluids that are going to lose if it is hot wet neck frequently monitor the location of sports is well ventilated in what may be cool.

If a kid is so faint must lie with their heads sideways as if to vomit and the lower the level of the body, while the doctor is called.

Water key to the temperature

The fact is that the water wets, but not much, something we can check to wash our hands without using soap. One of the tasks of detergent is precisely reduce surface tension so that water wet out garments and act more effectively. For this same reason, to moisturize skin creams are used instead of water.

Another peculiar property of the famous fluid element is its high heat capacity, that is, we must provide a large amount of heat to increase its temperature. In fact, is the second substance after ammonia which has the largest known calorific capacity. Therefore, if we make a bowl with warm water and another with alcohol, we will need more time to keep it so that the temperature increase in both equally.
This not only affects the time that we expect in the kitchen to prepare a soup, but something much more important: the effect of the global circulation of the oceans on the Earth's climate.
It should be borne in mind that a high heat capacity also means that the water cools more slowly, therefore must lose large amounts of heat to lower the temperature significantly. Thus, sea currents are capable of delivering a colossal amount of energy around the globe.

Thus, the Gulf Stream helps keep northern Europe warmer than the Labrador Peninsula, although they are the same latitude. Not only that. The "ability" to regulate the water temperature inside it has proven to be essential if we are here today.
Some sea ice, or sudden changes in temperature have prevented the chemistry of life.

This and more is water. Perhaps the best way to describe it are these words of one of the greatest experts in water chemistry and its relation to ecosystems, biophysicist Felix Franks: "Of all the known liquids, water is probably the most studied and least understood. "

Does the Air conditioning Make Bad?

The human body is capable from certain adaptation to the room temperature when the changes are progressive, let us remember as oneself temperature, for example 20ºC, they can be perceived as warm" "temperature in winter or I eat cold" "temperature in summer. However every time is more enhanced the climatizadores use and air conditioning, as much in particular homes as in public places of business, working centers and in the automobiles. These devices are conceived to improve the comfort, but you are not always this way, since sometimes your use can involve nuisances and even problems of health.

The factors that can contribute to these problems of health can be intrinsic to the own facilities and devices. Fundamentally they are the environment dryness that you/they cause, an excessively cold temperature, noises and a faulty maintenance of the facilities. The different susceptibility of people will also be a determinant factor.

Beginning with the first of them, the dryness of the environment created by the air conditioning is usually an irritating important factor, to which are allocated to be the lawsuit of quarrel-pharyngeal nuisances, dryness of eyes and sometimes dermal irritations. In susceptible people they can be something more than nuisances causing pharyngitis. In the users of contact len the dryness can be so irritating that you impede you the use of the same ones if they remain a lot of time in dependences with air conditioning.
Difference of temperature

When the difference of temperature is excessive among the dependences with air conditioning and those that don't have it or with the exterior, when passing a person of a place with air conditioning and therefore cold, to another that don't have it and therefore warm, or on the contrary, to pass of a place without air conditioning to another with air conditioning, a sharp change will take place in your room temperature giving place to reactions you wander you with sudoración and sometimes sensation of dizziness, in extreme cases the sudoración can be very intense, and even to take place a vasovagal authentic syncope.

The direct inhalation of cold air and the dryness of the air, very together or individually, they diminish the defensive barriers of the bronchial epithelium making you more vulnerable to the infections, so much bacterial as viral. Also the direct inhalation of cold air in susceptible people can unchain intense rinorrea and a broncoespasmo crisis in asthmatic people. Not they are uncommon the migraines, being able to unchain migraines or headaches

Another factor anything worthless you are the noise caused by the apparatuses, so much for the own machinery as for the step of the air for the conductions. This noise can pass desapercibido initially, but when we abort the place or you fade the installation you show the "noise that you had" and acúfenos can sometimes be suffered with sensation of auditory temporary forfeiture after remaining a lot of time in an air conditioning installation.
Big facilities

The "towers of refrigeration" of the big facilities or the compressors of the domestic apparatuses are places where heat is generated and you also condense the air humidity that cool down. These two factors favor the increment of microorganisms, being characteristic the increment of specially ubiquitous germs as the bacterium Legionella pneumophila and the mushrooms Aspergillus.

Legionella usually nests in the dampening systems and in the towers of vaporization, that makes that the infection can be transmitted by the air conditioning conductions, but also to the exterior. As the air conditioning it is also used logically in summer, the high temperature contributes to the survival of the bacterium in the ejected vapor, having been this the mechanism of the last you emerge there been in our country. The manifestations of the infection taken place by Legionella can vary especially from a catarrhal bare syndrome that pass desapercibido, until a pneumonia that put in hazard the person's life, if you suffer another illness that weaken your system inmunitario.

The Aspergillus is specially ubiquitous mushrooms that can be in the earth, powder, sheets of dry plants and many other places. They can also grow inside air conditioning facilities with a faulty clean-up. The inhalation of spores of Aspergillus is very communio but the illness is strange, practically only taking place in people with faulty defence, mainly to suffer another debilitating illness. The call bronchopulmonary allergic aspergilosis takes place in asthmatic people.

This exhibition can give the idea that the use of the air conditioning only produces nuisances and risks of contracting illnesses, however the frequency of these problems is petty comparing it with the great number of people that you/they use it.

We can also palliate partly them taking some elementary measures as:

* Not to put an excessively cold temperature that even force us to use certain coat clothes, as sweaters or jackets. The temperature should oscillate between 21ºC and 25ºC, depending from the physical activity to develop, but in any case it should be inferior at 21ºC.
* The border of temperature that prevent to reconcile a remedial dream is around the 27ºC, for that that at night in the places where you will fall asleep you are not necessary to make use of the air conditioning if you doesn't arrive to those temperatures and in any event not to put it more low of 25ºC.
* You are to lend care to breathe correctly for the nose when you is with air conditioning, since the nose will heat and you will humidify the air that we inhale. Let us remember that the cold and the dryness are two factors that make vulnerable to the bronchial epithelium, what are specially important in people with respiratory chronic illnesses as EPOC.

Regulatory schemes exist for the maintenance of the big air conditioning facilities that you are to observe conscientiously. But we should also take care of the maintenance of the domestic facilities. Although they are much plainner, you will have to clean the filters and conductions periodically and to clear every day the vessels of condensation of water if a system that make it alone don't exist.

The regulation of temperatures and hours of up-to-date use you have special importance in the sanitary centers, since for your own nature a concentration of people exists with problems of health that make them more susceptible.

A rational use of the air conditioning is safe and you produce more comfort than health risks. Your uncontrolled use will represent a bigger risk for the health to half and I release term for the problems caused to the environment, due to the excessive energy consumption currently pollutant that what can suppose nowadays at individual level.

Salamanders - Messages of Love Through Them

From centuries the human beings have searched heat and light behind, by means of the fire, using it to not only take the cold away from the body, but besides the soul. When lighting the vent, not importing the mime's size, the high one and intensity of the flames, they produced a hypnotic effect on the men.

This way he/she went that you were discovered to the elementary spirits corresponding to the element Fire: the salamanders.

With running then of the time, the human beings learned how to request you you help these beings interpreting the movement of the flames.

This communication form with the salamanders, he/she can make it any person. To discover that they predict the salamanders mainly in the affective plan, we will detail the procedure mode and the keys to decrypt these messages.

The procedure is very plain, but you require of a lot of patience and concentration. For you light a vent and you observe during some minutes the flames of the conflagration until melting mentally in your colors and movements. To the end of some moments, you will be contagious of that vehement energy that produce the fire and your heat. You observe with patience and in a completely careful way as the dark forms leave generating. Have a notebook and a pencil by hand to take the necessary annotations that well can represent them with the drawings that you perceive in those magic flames.

After all ésto, you look at what you have drawn and you are about interpreting what the salamanders have wanted to transmit you by means of the flames of the fire.

As you are about beings of natural energy, in general they are expressed by means of physiques of animals. Here we also expose a guide so that you can interpret them according to your meanings:

Bird: necessity of freedom.
Wolf: sexual pent-up desires.
Winch: double-cross and game to two tips in the love.
Butterfly: you thrill and heart purity.
Dog: companionship and good couple relationship.
Snake: overflowing sexuality, reciprocal desires.
Dragon: to be able to of the sex, necessity to like to the other one.
Bear: I use of the sex like protection mechanism.
Mouse: fears of the childhood that end in moral prejudgments.
Horse: encounter proximate pasional.

Not to heat alone water in an oven microwaves

WE REPRODUCE THE TESTIMONY OF A PERSON THAT SUFFERED SERIOUS BURNS WHEN TRYING TO MAKE BOIL A BOWL OF IT DILUTES

"TO TAKE INTO ACCOUNT AT HOME... I RETRANSMIT THEM A TESTIMONY: This is an I articulate that he/she speaks of the hazards of heating water in the oven of microwaves:

5 days ago my son of 26 anuses decided to take a cup of instant coffee. He/she took a cup of water and it put it to heat in the oven of microwaves (something that had already made before in different occasions). Not I know time exactly whereas it programmed it, but he/she told me that he/she wanted that the water boiled.

When the time finished, the oven faded and it took out the cup of the oven. While he/she looked at the cup, he/she realized that the water was not boiling; however, the water emerged directly to its face.

He unties her of their hands after the water has jumped to its face, due to the cumulative energy. All its face has wounds of 1º and 2º grade and it is very probable that the face is marked him/her, besides lost book credit the view partially of the left eye. While we were in the hospital the physician that attended it he/she commented that this type of accidents was very frequent and that he/she should never put on sólamente it dilutes to heat in the microwaves.

If he/she warms water this way he/she should always put on something in the water, a wooden stick or a bag of tea, but if he/she will warm sólamente the water it is better to use a heater of special water for these cases.

This is what the physics teacher said in this respect: "Thank you to send me the message noticing me about the water in the microwaves.
I have known about several cases: This phenomenon is caused by a well-known phenomenon as "super heating."

It can happen in any moment that the water is heated and especially if the tool that you this using is new. What happens is that the water warms a lot but quick of that that the bubbles you begins to form. If the cup is new he/she doesn't have any raspón or slot for where the bubbles can leave forming and they can begin to bubble the water that already this boiling, in such a way that the water goes warming on the time passing of boiling. (so to speak it boils... and it boils... and it boils... CDLR).

What happens then is that the water chokes, it is stagnant and to the contact with the air the water emerges with force for the contained energy.
It is what happens to all the charred drinks. When he/she becomes agitated the bottle being closed to the moment to open it the water it emerges for to the contained energy.

Please send this message to all their friends, they could avoid them a great pain and suffering."
