Monday, April 22, 2013 0 comments

All people must have felt the stress, anger, or other negative feelings. But not many people know how the processes in the body that cause negative feelings arise.

Negative feelings, either stress, anger, and others may arise from the performance of the three hormones in the body. Here are three hormones which are responsible for the stress that you feel, as quoted by The Huffington Post (19/04).

1. Adrenalin
Adrenaline is a hormone produced by the adrenal glands after getting a signal from the brain when enough stressful situations arise.

Adrenalin in cooperation with other stress hormones, namely norepinephrine are responsible for deciding your reaction when stress appears. Suppose that when you're driving, then there are other fast-moving cars will hit you. You swerve, stop and feel your heart rate increase. Your muscles tense, you breathe faster, and sweating. That is done by adrenaline.

In addition to increasing heart rate, adrenaline also increases the energy that allows you to do something to shy away from danger, and makes you more focused.

2. Norepinephrine
Adrenaline is a hormone similar to that released by the adrenal glands and is derived from the brain. Norephnephryne hormone function is to keep you focused and awake during stress. You will be more alert, awake, and focus on the issues.

Norepinephrine helps divert blood flow in the space do not really need for other body parts are more important, eg muscle or brain that makes you able to face the dangers well.

3. Cortisol
The hormone cortisol is also produced by the adrenal glands and is also known as the stress hormone. The hormone that determines your response to stressful situations and that can be stressful.

Compared with other hormones, these hormones work more slowly. First, part of the brain called the amygdala will determine threats or situations that can cause stress. Then the signal is sent at hypotalamus. Hypotalamus CRH produces hormones related to ACTH. ACTH then signals the adrenal glands to release cortisol. Wow, quite a long journey instead.

In many circumstances the danger, the hormone cortisol can save lives. Still too much of the hormone cortisol production is also not good for the body. These hormones suppress the immune system, improve blood pressure and blood sugar, causing acne, obesity, and others.

Above three hormones responsible for the stress that you feel and how your body deal with it. In some cases the above hormones can be useful. But too much stress hormone production is also not good for health.

Too old to drink milk make baby less iron? - Although breast milk is considered as the best nutritious food for babies, but a study shows that babies who are too old to drink milk possible iron deficiency.

"We found that after one year, the longer the baby feeds her mother, the higher the risk for iron deficiency," said researcher Dr. Jonathan Maguire, a pediatrician from the Li Ka Shing Knowledge Institute at St. Michael's Hospital, University of Toronto, Canada.

The study, published online in the journal Pediatrics on April 15, the findings suggest an association between duration of breastfeeding children with their propensity to consume iron deficiency can cause anemia. Iron is an essential nutrient, especially for children. Iron is needed in the development of the nervous system and brain.

World Health Organization recommends exclusive breastfeeding for the child for six months, then introduce them to food ation supporters. Based on research, WHO allow breastfeeding to children aged two years or more.

Researchers looked at 1,650 children aged between one and six years with an average age of three years. No one is suffering from a rare disease. Yet they found a decrease in the level of iron as much as five percent of each additional month of lactation. Researchers also found the same in children who consume too much dairy cows.

"Cow's milk does not contain a lot of iron, for that breast milk is better for the child during the first year," Maguire said, as quoted by Health Day News (19/04).

Meanwhile, one of the doctors laRabida Children's Hospital in Chicago still recommends breast milk for the baby. According to him, the iron in the mother can be given to children more effectively to children growing up. After that, the need for iron increases and the child would have to be supported by other foods.

Closed windows jeopardize patient in hospital

Her hospital room had a window covered are known to increase a patient's risk for infection, according to new research. British scientists using carbon dioxide as a tracer gas when doing this experiment. They find out whether the infection will spread at a hospital with a room that usually contains up to 30 beds in one room.

"By measuring the concentration of carbon dioxide in a certain time, we can see the quantity of gas exposure on each patient and see the level of risk in these patients," said researcher Laura Pickin from the University of Leeds, as quoted by Health Day News (19/04) .

When the window is open space, pretty good indoor ventilation and the risk of infection is low. But the danger of infection is increased four-fold when the window is closed. It is the same even when the researchers tried the room containing only six or eight beds.

With natural ventilation from a window, the patient is safe from the risk of infection. But this soon changed when the windows were closed and replaced with air conditioning. European hospitals usually do this during the winter. In Indonesia, because there is no winter so it's good to keep the windows open whenever possible to avoid the spread of infection in patients.
