The Origin of the Sauna

Sauna appeared for return of century III before Christ.

In mountains of the region of the Finlândia, a group of woodcutters looked shelter for the cold.

Observing it washes that she was expelled for volcanos, them had constructed a hut of closed rock in oven form.

They had stoked fire to the firewood, and after a period of 8 hours, them they had left smoke to escape and they had entered in the hut.

After warm, the diving in the water of refreshed them to the lakes and caused a thermal shock.

Mayans

The Mayan people has uncertain origin, but old Holy Writs can bind it the platonic people to it atlânte. The Mayans if had installed where today Mexico is southd, Guatemala and Honduras for return of 1000 year B.C. the succession of archaeological discoveries, from the passed century, more indicates the development of one of the notables civilizations of the New World, with architecture, sculpture and ceramics sufficiently elaborated. Without a doubt none, this civilization if exactly based on the knowledge of the archaic, previous cultures to century X B.C. But, it was the decipher of the ideogramas of the Mayan writing that allowed to partially reconstitute the history of this magnificent people. The history of the Mayans can be divided in three periods: the daily pay-classic (1,000 B.C. the 317 d.C.); the classic or Old Empire (up to 889 d.C.); e after classic or the New Empire (also known as “Mayan renaissance” up to 1697). Of the daily pay-classic age little if it knows, but it can affirm that, in this period, already it existed a social and religious structure as a sacerdotal classroom specialized in mathematics and astronomy. Probably, it was at this time that was created the Mayan calendar. The end of the daily pay-classic age and the start of the classic age had been established on the basis of the first dates that could have been deciphered in monuments.

The Ruins of Copán, the west of Honduras, had been discovered in 1570 by Diego Garci'a de Placio. One of the places most important of the Mayan civilization, these Ruins had not been excavated until century XIX. Its ortalezas and imponent public squares characterize its three main phases of development, before the city was abandoned at the beginning of century X.

The advanced knowledge that the Mayans possuíam on astronomy, as solar eclipses and movements of the planets, and on mathematics, had allowed them to create a cyclical calendar of notable precision. In the reality they are two overlapping calendars: tzolkin, of 260 days, and haab of 365 days. Haab was divided in eighteen months of twenty days, more five days free. To date the events they used the “short account”, of 256 years, or then the “long account”, that it began at the beginning of the Mayan age. They had determined with incredible exactness the lunar year, the trajectory of Venus and the solar year (365 days, 5 hours, 48 minutes and 45 seconds). They had invented a system of numeration with base 20 and had notion of number zero, which had attributed a symbol.

The Mayans used a hieroglífica writing that not yet total was deciphered. The scientists, studious of the Mayan civilization, had proven that the old ones had made many comments of the Sun, during its ticket for the zenith, in the ceremonial square of Copán. This discovery reaffirms that the Mayans had been great astronomers and that they had lived its period of esplendor enters the 900 years 250 d.C. During the solstícios and the equinoxes, the position of the Sun generates alignments special between some monuments, altars and other structures of the main square of the Mayan archaeological small farm of Copán.

Today, the valley of Copán, as other archaeological small farms, is declared Patrimony of the Humanity, protecting the center of the ceremonials of the Mayan civilization, that floreceu in Central America in the first millenium of the Christian Age.

Acariciar dog can help sick people of the heart

To pass some minutes acariciando a dog can diminish the anxiety of a sick person of the heart and even though to help inthe recovery of it during a hospital internment, researchers of U.S.A. in this tuesday had said.

The beneficial effect of the contact with the animal had been bigger of what when the sick people with cardiac insufficience had received the visit from a volunteer or when they had been left alone, had affirmed the scientists during a meeting of the American Association of the Heart.

“This therapy justifies that let us analyze with seriousness this option as a therapy auxiliary for the case of people with cardiac insufficience. The dogs represent a great comfort”, said Kathie Cole, nurse of the University of the Medical Center of California (U.S.A.), that it commanded the study.

“They leave the people happyest, calmer. They make with that the people feel themselves loved more. This is something very important when the person is if feeling rightened and badly.”

It estresse it can get worse the picture of a cardiac sick person, but It glue said that nobody had so far evaluated with depth if measured simple of relief estresse of it, as to acariciar an animal, could help in such a way that it could be measured.

The team of Glue discovered that one visits of 12 minutes of a dog helps the functions cardiac and respiratory, diminishing the pulmonary pressure, reducing the harmful hormone production and fighting the anxiety.

The scientists had evaluated 76 people with cardiac insufficience interned in a hospital. From this group, some had received the visit of a dog per 12 minutes, others had received the visit from a trained volunteer and others had been alone.

The anxiety indices had fallen 24 percent for the sick people visited for a dog, 10 had fallen percent for that had received the visit from a person and had remained unchanged for whom they had not received no visit.
