Children should not eat too many sweets:

Eating many sweets can lead to eye disease in children. Sugar metabolism generates acidic products, as destruction of calcium and chromium (highly alkaline). The lack of this substance increases the pressure inside of the lens, changing the light refraction of the eye, causing eye more susceptible to myopia.

In addition, the following reasons also increases diseases of the eye:

- limited vision :

Eye of students in urban vision is always limited by the city has many obstacles, hard-looking eyes adjust to near and far.

Gradually adjust the capacity of the eye and eye degenerative only familiar look close, leading to myopia. For city children exposed to natural large eyes adjust to near and far is the prevention of eye diseases as well.

- Lack of sleep :

Due to lack of sleep, the eyes have to work, not relax it gradually reduced capacity to adjust, easily lead to myopia. Make sure to sleep 8-10 hours a day, reducing the intensity of learning and ensuring other conditions (tables, chairs, posture, lighting ...).

- Noise :

The noise levels greater than 90 db, the sensitivity of retinal rod cells of the eye down, the eyes take longer to distinguish brightness.

As the sound up to 95 db, 40% of cases of dilated pupils. When the noise level is 115 db, the ability to adapt to the light intensity decreased 20%, the ability to distinguish color reduction.

- Inhalation of tobacco smoke : The tobacco dicyanogen CN2, if the accumulation in the body will cause poison, clearly affected the operation of the eye.

Add a reduced risk of heart disease

Eat more sardines reduce blood triglycerides:

Even when blood cholesterol levels normal, you still have heart disease risk. High levels of fats called triglycerides also increase the risk of heart disease, stroke and diabetes. So, if you do not want heart disease, try to reduce blood triglycerides.

Here are some methods reduce triglycerides magazine Mayor Clinic Health Letter September issue of the American proposals:

- Limit use of foods high in sugar like cookies and soda water.

- Reduced fat and exercising at least 30 minutes a day.

- Eat fish rich in omega-3 fatty acids such as mackerel, salmon, herring, sardines, tuna.

- If diet and exercise does not reduce levels of triglycerides, talk to your doctor to be taking down this substance.

Measures to reduce discomfort when high

When high, the body needs time to adapt:

If you like skiing in the mountains or other forms of similar activities at high altitudes, do not be surprised if you find yourself a little dizziness, nausea in the first few days. The expression comes from the reduced oxygen content and humidity of the air as high.

The common nuisance related to altitude include: nausea, insomnia, diarrhea, constipation, headache, shortness of breath, stuffy nose, fatigue, cough, heart palpitations.

- Eat lightly and drink plenty of water.

- Sleep full.

- Pay attention to the reactions of the body and reduce the intensity of activity if one of the manifestations described.

Deaf adversely affect the development of young

Listening skills help children develop harmoniously:

Compared with normal children, deaf children often perform the movements slowly, sometimes intermittently. Deaf also affect the child's gait. The vast majority of children with severe hearing loss tend to be shuffled to go. Meanwhile, ordinary people ask to hear his footsteps should generate conscious step easier.

Advocacy, children normally sit from 7 months, walking at 12-15 months, from two to two and a half ... then all bedwetting, but they are deaf often grow more slowly than the landmark .

Intelligence also clear differences between the two groups. Children with hearing loss often less memory. If for deaf children and young fresh look at the paintings along with simple shapes such as circles, triangles, squares ... in 30 seconds and then asked to draw back, that deaf children will draw more slowly.

How to treat insect bites

Bumblebees, a type of bee venom is extremely toxic:

To relieve itching when the dog tick, mosquito, deep straw or burning ants, apply to the place burned down a few eating toothpaste or vinegar, lemon juice, onion, garlic, moth balls, chopped onion. The feeling will quickly soothe itching and loss.

* The poisonous insect bites : For topical application to human milk, will be painful.

Also, if the skin is itchy spot, you can use fresh leaves crushed melon or saline applied to clean, with good results.

Using iris cells to treat retinal

The retina contains cells extremely sensitive to light:

The cells in the iris (iris) can be genetically modified to form the retinal cells. This achievement opens to seek new materials to repair damaged retinas - the cause of many diseases of vision.

Stimulated a gene from mouse cells in the iris. Result, these cells were self-forming properties identical to the retinal cells (extreme sensitivity to light).

"We have implanted the modified cells in vitro gene in the mouse retina. After a few days, blind mice reacted to light."

The scientists said that in the future, with the help of this method, they will withdraw some cells from the iris to feed patients and transplanted into the retina. However, they still have to wait 1-2 years to eliminate the side effects that may occur during transplantation.

Give the child fever medication how much is enough?

The health professionals has released new guidelines, a more detailed description of antipyretic doses corresponding to the child's age, after a recent survey found 27% of newborns with paracetamol overdose.

Who led the study, said parents and doctors were "overconfident" when inventory paracetamol for children.

However, in the journal British Journal of Clinical Pharmacology of recent, he added that it is difficult to know exactly how much a child needs medication, and it depends on age and weight.

With this new guidance (expected to apply in the UK later this year), it will split the age group of children to prevent drug abuse. For example, children 6-12 years old are now the same group, taken from 5 to 10 ml each time, using up to four times a day, but the new guidelines, children will be divided into three groups, a two-year-old one level, with increasing number of drugs.

In addition, drug formulations for children at different ages and different. Specifically:

Formulation Age Dose

Suspension infant paracetamol

(120mg/5ml) 3-6 months 2.5 ml

6-24 months 5 ml

2-4 years 7.5 ml

4-6 years 10 ml

Suspension than paracetamol for children 6 years of age (240mg/5ml) 6-8 years 5 ml

8-10 years 7.5 ml

10 -12 years old 10 ml

Paracetamol is antipyretic, analgesic familiar to most of the parents for children.

"This change to ensure children receive the maximum dose of paracetamol priority, consistent with age. And because it very clearly divided doses, so parents will be easier to calculate the amount with their children. "
