सेहतनामा : निरापद नहीं हैं शैम्पू और लोशन शिशुओं के लिए


( १)गर्भधारण से पूर्व पिता की खुराक भी अपना रोल प्ले करती है। गर्भस्थ की सेहत को असरग्रस्त करता  है खुराक में खासकर विटामिन -B9 ,का स्तर जिसे फोलेट   भी कहा  जाता है महत्व रखता है। 

अनेक पत्तेदार हरी सब्ज़ियाँ ,अनाज ,फल ,फलियां और मांस इसका 

स्रोत हैं। 

(२)जोर जोर से बोल बोलके पढ़ना और शिशुओं और नौनिहालों ,बालकों से बतियाना दिमागी विकास को एड़ लगाता है ऐसा करते रहने से कम उम्र से ही दिमाग के विकास की रफ़्तार द्रुतगामी होने लगती है। 

(३) मच्छी में मौज़ूद स्वास्थ्यकर वसायें मस्तिष्क आघात (ब्रेन अटेक ),दिमाग के अपविकासी रोग समूह डिमेंशा आदि के खतरे के वजन को कम करते हैं। 

(४)निरापद नहीं हैं शैम्पू और लोशन शिशुओं के लिए 

सौंदर्य प्रसाधनों की भंडारण अवधि बढ़ाने के लिए इनमें चंद रसायन परिरक्षी(संरक्षी ) के रूप में मिलाये जाते हैं। इन्हें parabens कहा जाता है। . 
अमरीकी रसायन संघ के एक विज्ञान प्रपत्र 'Environmental Science &Technology में प्रकाशित एक ताज़ा अध्ययन के अनुसार ये रसायन खिलौनों में ,परसनल केअर उत्पादों में भी पसरे हुए हैं। 

अमरीकी रोग रोधी तथा रोग बचावी संस्थाओं के केन्द्रों के अनुसार अमरीका की ९० % आबादी इन रसायनों के प्रभाव में अपने अनजाने आ चुकी  है।भले हमारा शरीर इन्हें सरल रूपों में तोड़ने की कूवत लिए है फिर भी मानव विसर्जित मूत्र ,मानवीय रक्त ,तथा ब्रेस्ट मिल्क में इन रसायनों की मौज़ूदगी दर्ज़ की गई है। 

इन रसायनों से असर ग्रस्त होने (प्रभावन )और स्पर्म डेमेज, स्तन कैंसर ,तथा दमा के खतरनाक तौर पर बढे हुए जोखिम की ओर इस अध्ययन ने इशारा कर दिया है।   

(५) Use narrow glasses to drink less .A study shows that those asked to serve themselves wine in wide glasses poured around 12% more .

(6)दिन भर डेस्क से चिपके काम करते रहने से जीवन शैली रोगों का ख़तरा बढ़ जाता। अलार्म लगाइये घड़ी  में हर घंटा बाद सीट छोड़के टहलकदमी कीजिये दफतर के गलियारों में।  



Humans are hard -wired to enjoy the calm of the country side ,while cities make us confused ,anxious and aggressive -even if we were born and raised in urban areas ,scientists have found .The results could be due to the fact humans lived in rural environments for hundred of years ,researchers said. 

Eating two portions of oily fish a week could help ward off a stroke, research suggests.
Scientists have found that eating two helpings of oily fish - such as salmon, trout or mackerel - every week could moderately reduce risk of a stroke.

 Why is vitamin B9 necessary?
Vitamin B9 is essential for human growth and development, encourages normal nerve and proper brain functioning, and may help reduce blood-levels of the amino acid homocysteine (elevated homocysteine levels have been implicated in increased risk of heart disease and stroke). Folic acid may also help protect against cancers of the lung, colon, and cervix, and may help slow memory decline associated with aging.
Pregnant women have an increased need for folic acid: it supports the growth of the placenta and fetus, and helps to prevent several types of birth defects, especially those of the brain and spine. Pregnant women and women of child-bearing age should take extra caution to get enough folic acid (see below for recommended amounts).

 What are the signs of a deficiency?
Deficiency has been linked to birth defects, low birth weight, pregnancy loss, depression, memory loss, and cervical dysplasia. Alcoholics, pregnant women, and people living in institutional settings are at a higher risk of vitamin B9 deficiency.

Parabens: What are they, and are they really that bad?

Parabens are a common cosmetic ingredient—and, lately, the object of much vilification. Find out what they really are and whether you should be seeking out paraben-free products

You may have noticed lately that “paraben free” labels have been popping up on some beauty products at the drugstore and elsewhere. Parabens are the most widely used preservativesin personal care products; they stop fungus, bacteria and other microbes from growing in your favourite creams and makeup, especially in the moist, warm environment of a bathroom.

Their names are a mouthful—methylparaben, ethylparaben, propylparaben, butylparaben and isobutylparaben. You’ll find them listed on thousands of personal care products such as shampoos, mascara, foundations and body lotions. But over the past few years, a debate has been building among scientists, product safety regulators and cosmetic manufacturers about whether these ubiquitous chemicals, used for almost 70 years, may actually be harmful to our health.

Some of the questions being asked: Is the rising incidence of breast cancer linked in part to the fact that parabens, which have a weak ability to mimic estrogen, have been found in breast cancer tumours and can be isolated from other body tissues? Are declining sperm counts and increasing rates of male breast cancer and testicular cancer related to the fact that these chemicals can be absorbed into our skin, potentially disrupting our endocrine systems?

We don’t know yet. But some researchers feel there may be reason for concern. One of 
the most vocal is Philippa Darbre, a senior lecturer in oncology and researcher in biomolecular sciences at the University of Reading, in England. She specializes in the impact of estrogen on breast cancer. In 2004, Darbre’s team published a pivotal study that detected parabens in 18 of 20 samples of tissue from breast tumour biopsies. Her study didn’t prove parabens cause cancer, only that they were easily detected among cancerous cells. The study was criticized for not comparing paraben levels in normal tissue, but nevertheless, the results called out for more investigation.
“We’ve known for more than 25 years that estrogen exposure is linked to breast cancer development and progression; it is the reason tamoxifen [commonly prescribed to women with breast cancer] is used to disrupt estrogen receptors,” says Darbre. “So it is not such a leap to be concerned that repeated, cumulative, long-term exposure to chemicals that weakly mimic estrogen might be having an impact.”
Darbre is particularly concerned about lotions and deodorants being applied under the arms or near the breast, and hasn’t used underarm deodorant herself for 10 years, opting instead to use just soap and water. She notes that research has found that roughly 55 percent of all breast cancer tumours occur in the upper outside portion of the breast, the section closest to the underarm. The U.S. National Cancer Institute has partly dismissed the claim, maintaining that at present, there is no decisive evidence to conclude that the parabens in these products are linked to breast cancer, but that more research is needed.
