Some Brazilian states are suffering from low temperature records in recent days. São Paulo, for example, had the coldest morning in 22 years on the last day 13. If you, like most Brazilians, does not have a heating system at home, check out some tips to fight it even without heating:
1. Ventilate, but in moderation
It takes five minutes to ventilate the house completely; ten if your windows are small. Do not do it in cold times and try to do when there is sun. "In the morning, immediately after waking up, is the best time," said Barrera Viera, an energy expert.
2. Save the sun's heat
Ideally, when the sun is beating the house, all the possible openings are closed, but without any obstacles, such as blinds or curtains that prevent the entry of light. Do not open the windows because, otherwise heat the house accumulated gradually go away.
In contrast, when the sun goes down, the process should be the opposite: close the curtains and blinds to keep the heat derived from the infrared radiation (from the sun) to dissipate. The order of the method does not necessarily depend on being in the morning or afternoon: it may be that a certain room receives no light in the morning but in the afternoon, when they should take advantage of the presence of the sun.
3. Electrical tape
An economic remedy that can be found in any hardware store is the tape, used to plug existing gaps in doors, windows and other places, in order to prevent air circulation from a warmer room for more cold.
"So you cut the typical sense of a stream of air that enters not know where and what is much more common than we think," says the president of the College of Professional Environmentalists Andalusia.
4. Hot water bottle in bed
It's time to go to the warmth of the bed. But the mattress and blanket will take a few minutes before to preserve the warmth of his body. To avoid collision with the cold sheets, you can preheat the bed by placing a hot water bottle between the mattress and blanket to lie without fear.
5. Colors relate to station
Noticed ever more heat than common when using a black blouse under the sunlight? This is due to the colors and the temperature are related: the darker an object, the more heat it absorbs, as confirmed by a study by the State University of Campinas (Unicamp), in São Paulo, according to which the black captures 98% of the heat that reaches it, then gray (90%) and dark green (79%).
Of course, this assumption also applies to the room. This is due to the white or light colors absorb heat from the sun, but return the light spectrum, so that filter low energy. Arranging a dark chair to the hostile winter afternoons is not a bad idea.
6. Carpets
"The floor is the constructive element that has greater energy loss. In winter is at an average temperature of 10 to 12 degrees, while in the summer reaches 14 or 16, "says Barrera Viera, which recommends the use of textile solutions, such as carpets, for without being insulated, retain high temperatures. However, the ideal floor to combat the cold is the wooden floor or carpet, more comfortable and warm the marble floors.
7. blanket material
There is something more classic in winter the days of film and blanket? Wool is able to, in cold and wet conditions, generate heat due to the thermal insulation it provides and also by its absorption properties of up to 30% of own weight in water vapor without transmitting moisture feeling, according to a study published in 2009 by the Argentine website of Animal Production.
Other options are a fleece blanket and flannel, polyester compounds and cotton or synthetic fibers, respectively.
