Lampu Warna Biru, Pengusir Kantuk Pengganti Kopi yang Tak Pakai Beser

Color Blue Lamp, repellent Sleepiness Coffee Substitute Not Wear Beser
Jakarta, proved to be the most potent coffee to ward off drowsiness. But the side effects of coffee are less favored because it makes the car drivers beser and must often stop looking for the toilet. Alternatively, pair blue lights in the cabin.

Scientists at Universite Bordeaux Segalen recently proven blue lights as potent as the effects of caffeine in coffee in ousting sleepiness. Obviously without beser or frequent urination as happened after drinking coffee.

The findings are expected to inspire the design of the car or vehicle safer in the future. By entering the blue light as part of the interior design of modern cars, the number of accidents caused by drowsy drivers are expected to be reduced.

Experiments on 48 drivers who cover a distance of 400 km shows, the error rate is reduced thanks to the driver who made ​​the blue light. Violation of road markings done 15 times by drivers who are exposed to blue light, 13 times the driver who drink coffee and 26 times on drivers who do not get anything.

Research published in the journal PLoS ONE this proves that the color blue can improve alertness by stimulating the ganglion cells of the retina. Quoted from the Daily Mail, Thursday (11/29/2012), the cells are found in the layers of the retina located at the back of the eyeball.

Retinal ganglion cells are also connected with the nerves of consciousness. Therefore, it can induce the secretion or release menungkatkan melatonin, a hormone that makes people be awake and stay alert all night.

Various previous studies showed that a third of the victims of road accidents related to drowsiness. Because of drowsiness, the driver could lose alertness, reflexes and the ability of visual perception in the sense of vision decreases.

Jakarta, this time high blood pressure can be treated with changes in diet or consumption of drugs that lower blood pressure. But has now found a new procedure uses radio waves to destroy overactive nerves around the kidneys to help relieve high blood pressure, aka hypertension.
Minimally invasive procedure called catheter-based renal denervation (catheter-based renal denervation) using a probe or some sort of wire that is inserted through the femoral artery (major artery in the thigh) which will be issued a 'shot' of intense radio waves to destroy nerves in about kidney acting overly active in hypertensive patients, especially those that are susceptible to certain drugs.
The team of researchers from Australia who created this technique believe that the procedure lasted for 30 minutes is going to revolutionize the treatment of high blood pressure to end the use of certain pills to normalize blood pressure.
"Because achieving a significant reduction in blood pressure, reduction in levels of heart attack and stroke in patients can reach more than 40 percent," said lead researcher Professor Murray Esler of Baker IDI Heart and Diabetes Institute in Melbourne, Australia, reports the Daily Mail, Thursday (12/20/2012).
"Kidney participants had suffered no damage and functional disability. Means there is no negative effect on the long-term health of patients affected by this procedure," he continued.
The findings, published in the journal Circulation also shows that six months after treatment with this procedure, 83 percent of patients reported a decrease in systolic blood pressure of at least 10 milliliters of mercury, while 79 percent of patients in the same group known to be able to maintain it until the year-long decline.
Responding to the study, Professor Gareth Beevers of Blood preasure UK stated, "The procedure is very attractive because it can treat so many patients with hypertension and blood pressure returns to normal levels. Even so the procedure will lead to the use of drugs control blood pressure becomes obsolete .
