Nothing more pleasant than running on the shore while enjoying the scenery and feeling the refreshing breeze. Any physical activity that is practiced in the hottest hours of the day makes a lot of hard to lose heat by sweating, especially if there is much moisture.
However, the body is already overheated because of climate, and is even hotter depending on the exercise itself. The result is a great loss of water and minerals, which gives rise to all sorts of trouble. For an idea, researchers from the University of Chicago in the U.S., checking out the reaction of the muscle exercises pulled under a temperature above 30 degrees. In the study, the volunteers ran in these conditions and, after a rest they were forbidden to take water. Result: their muscles showed less power to fire than when they were hydrated.
“The dehydration affects the functioning of the muscles. Then, the person may have sprains by not controlling the body properly, “says Paulo Roberto Santos-Silva, of the Group of physiologist of Sports Medicine, Hospital das Clinicas in Sao Paulo. After all, water and minerals are very important to the muscles. And with those two components missing, the legs do not respond as they should, culminating in stumbling and falling frequently, lead to a twist on the ankle, for example.
This imbalance of water and minerals also causes painful cramps – involuntary muscle contractions. Moreover, when the thermometer shoots, small problems, such as an edema. “With that, a minor injury may be worse without the person understands,” warns the orthopedist Ana Paula Simões, the Group of Sports Trauma of the Santa Casa da Misericordia de Sao Paulo.
Even those who never had heart problems is hindered. Again, behind is excessive sweating, which is losing minerals – sometimes, they are important because they help regulate the heartbeats of the main muscle of the body. “In the absence of them, especially without the potassium, increases the risk of arrhythmia,” exemplifies Zogaib Paulo, physiologist at the Federal University of São Paulo, UNIFESP. This is without counting on the removal of water by excessive sweating has the power to – pasme! – Generate a clot. If he goes to the heart, the danger is of a heart attack. And if the clot that reaches the brain, a stroke.
Even though it is possible to prevent it. Just observe some basic recommendations. “In the extremely hot days, try not to work between 8am and 6pm hours,” Santos-Silva teaches. Thus, unless you force your body. It is also essential to remain well hydrated. The recommendation of experts is to take at least a glass of water every 20 minutes while working out. Only then the system of thermoregulation – responsible for the temperature of the body – is stable, preventing overheating. And always, always right, seek the guidance of a professional.
Following these strategies does not mean giving up the signs noted that the body emits when exceed the limits. “The first one is the dry mouth. In that case, stop the activity and drink more water, “says Emerson Silami Garcia, coordinator of the Group of thermoregulation and fatigue mechanisms of the Federal University of Minas Gerais (UFMG). Another warning that the time to stop already behind are the dizziness. “They happen when the blood circulation can no longer meet the demand of the rest of the body while he is exercising. Then, on little blood to the brain, “explains Zogaib. Otherwise, just avoid synthetic fabrics – they do not absorb sweat and prevent the skin breathe – and get out there enjoying the delights of the summer in a mind to recommend under suitable temperature. That is, practicing physical activity.
Only 20% of the energy produced by the body is converted into motion. The rest turns into heat

Why running?
When you are running there is this little person thats talks to you and this little person says: “I’m tired, my lungs are ready to pop, I’m so hurt, I’m so tired, there is no way I can possibly continue”. And you want to quit. right?
If you learn how defeat that person when you are running will learn how not to quit when things get hard in yout life.
Reading
the reason of reading is so important is that there were gazillion of people that has lived before all of us, there is no new possibily problem we can have with the parents, school, mate, bully, with anyone. There is no problem we can have that someone hasn’t already solved and wrote a book about it.
For the people who don’t like to read it, check out the video:

According to the team of the Lutheran University of Brazil (Ulbra), the discovery, made in the municipality of Dona Francisca, in the central region of the state, strengthening the theory that South America and Africa were connected by land.
The species, named Luangwa, has similar characteristics to the mammals of today. The scientific name was given in tribute to the first description of a cynodont discovery in the valley of the Luangwa, Zambia.
“The existence of two fossils of the same group in regions so far reinforces our theory that the continents were united by a single block of land (Pang),” said biologist Roberto da Silva Lucio, one of the researchers responsible of the finding, along paleontologist with Sérgio Furtado Cabreira.
According to the team, the good condition of the fossil will facilitate research on the biology of the animal. “Around 90% of the skull is very well preserved in relation to other materials found, as jaws and teeth, which are well fragmented,” said the biologist.
Cynodonts
Analysis of the fossil’s teeth so far indicate that the cynodonts could be omnivores, herbivores and carnivores. Luangwa was an omnivorous group, which is fed with a varied diet of plants, invertebrates and small vertebrates. One could measure a few centimeters in height, but also reach up to 2 m.

The fireworks of about 24 tons of fireworks, inspired by the “four elements of nature,” the earth, fire, water and air, tourists and joy, lasted just over 20 minutes, because of a problem the ferry that was next to the pier 4.
Some transatlantic had permission to watch the fireworks show very close to the eight ferries throughout the sea of Copacabana.
After the turn, the public auction to the sand and sidewalk early accompanying the concerts of Revelation, Mart’nália. To ensure safety, the military police increased by 42% the effective in comparison to last year and towers used to monitor the movement.
