Threat associated with stress
Threat associated with stress – Stress arising through work or school, can lead to serious health problems. Such as cardiovascular diseases or the development of depression. Engineers from the lab ETH Zurich have developed in connection with this small device that allows you to measure stress levels. The instrument combines the measurement of skin conductance, heart rate and breathing with the measurement of stress hormones in saliva.
Fear like perfume
Fear like perfume – Researchers from the University of Munich showed that fear is spreading through the air. Just to our brain she sensed fear pheromones contained in sweat stressed people and they begin to be afraid. Feeling fear pushes us to hasty and risky behavior. Responsible for this state of affairs is the structure located symmetrically over our ears, namely the amygdala.
Attractiveness among stressed group
Attractiveness among stressed group – British scientists at University of Newcastle. Conducted an experiment on 81 volunteers, who had to assess the attractiveness of 10 women from very thin to obese. Half of the men just before the assessment has been subjected to stress. It turned out that the stressed group plumper women were more attractive than their calmer counterparts.
Nine-banded Armadillo – Sleeps 80% of life
Nine-banded Armadillo – Inhabits mainly in South America, and even was the mascot of the World Cup in Brazil. This is not an active animal. Armadillos are sleeping 80% of their lives. However, they have an interesting feature on reproduction. Female under stress can postpone childbirth up to 4 months.
Strong psychoactive substance
Strong psychoactive substance – C12H22O11 – a powerful psychoactive substance. Just as cocaine, alcohol or nicotine to the extent stimulates the reward system in the brain that a person can become dependent. In this chemical formula, however, doesn’t hide any illegal drug. But the Sucrose – better known as sugar, which we all use every day in their homes.
According to a recent study conducted at the University of New South Wales in Australia, sugar – especially in the form of sugary drinks – a negative impact on memory (as well as chronic stress). Researchers observed two groups of rats: suffering from stress and emotionally stable. The latter for some time given sweetened drinks. We found that in the rat hippocampus consumed sugar (in the region of the brain responsible for memory) was broken to the same extent as in the stressed animals.
Especially be careful to feed children sweets. Already a few years ago, they saw US researchers, who served for a month rats sweet drinks. It turned out that sugar had no significant impact on the brain of older rats, and impair learning and memory ability in the young.
Walnut subjected stress
Walnut subjected stress – Walnut alone can produce methyl salicylate – happens when subjected to stress, eg. If the air is polluted by all the time. Researchers believe that the walnut trees in this way strengthens their biochemical defenses and prevent infections.
Abnormal stress reactions
Abnormal stress reactions – Neuroscientist Rachel Yehuda said abnormal stress reactions in infants whose mothers shortly before becoming pregnant survived the attack on the World Trade Center in 2001. Because of experience related to the Sept. 11 changed obviously control the expression of many genes. Modified hereditary characteristics, in this case, the pattern of expression, are transmitted to offspring.
There is no doubt that memories leave traces in our genome
– says Yehuda.
Sensitive touch – The sensual intoxication
Sensitive touch – The sensual intoxication combined with a feeling of happiness can propel us also touch sensitive. Desired bodily contact causes the release of the so-called. hormones stroking, e. g. oxytocin. It has been proved that with this substance suffering from neurosis or depression female faster return to mental balance. In men, reduced blood pressure and stress.
