विज्ञान विविधा :शोध की खिड़की से ,एवं इलाज़ से जुड़ी भ्रांतियां और सच्चाई

विज्ञान विविधा :शोध की खिड़की से ,एवं इलाज़ से जुड़ी भ्रांतियां और 

सच्चाई 

(१) शोध से इल्म हुआ है ,दीर्घावधि से योगाभ्यास करते आ रहे लोगों में रोगों से लड़ने में सक्षम जीवन इकाइयां (disease fighting genes )बड़ी तादाद में मौजूद रहती हैं। 

(२) भूखे -प्यासे लोग बीवियों से ज्यादा झगड़ा करते हैं। खून में शक्कर का स्तर गिरने पर पति अक्सर अपनी चिड़चडाहट पत्नी पर चीख कर निकालते हैं। हंगरी इज़ एंग्री ,काल हिम हैंगरि।मर्द को जीतने के दो आसान रास्ते हैं पेट (रसोई )और सेक्स -तृप्ति(बेडरूम  )।   

(३) पिता से व्यवहार करने का ख़ास अंदाज़ ही नौनिहालों तक नहीं पहुंचता है ,स्ट्रेस भी अंतरित होती है। चूहों पर प्रयोगों से इल्म हुआ है चूहों के नर नन्हों  में स्ट्रेस स्माल राइबोन्यूक्लिकअम्लों को असर ग्रस्त करती है। इससे आइन्दा आने वाली संतानों ,में अवसाद के लक्षण आ सकते हैं 

चिकित्सा से जुड़े मिथ और यथार्थ :

(१) च्यूंगम सात सालों तक पेट में पड़ी रहती है ?

भले गम में इलास्टोमर्स के अलावा कई रेझिन (राल यानी वृक्षों से प्राप्त एक किस्म का गौंद ,resins  ),कई वसा या तेल से बने मोमियां पदार्थ (waxes ), मौजूद रहतें हैं लेकिन हमारा सक्षम पाचन तंत्र (पाचन मशीनरी )हमारी अंतड़ियां तमाम किस्म के अपच को गुदा का रास्ता दिखला देती हैं। हम कई खादय रेशे भी तो खाते हैं रोज़ जिनमें  कई अपचनीय बने रहते हैं। चिप -चिपि च्युंगम को भी यह नायाब मशीनरी निकाल बाहर करती है। तो ज़नाब महज़ मिथ है ऐसा मान लेना की च्युंगम सालों साल पड़ी रहती है आमाशय में। 

(२) फ्ल्यू का टीका ही फ्ल्यू की वजह बन जाता है ?

महज़ मिथ है यह भी सच्चाई ये है :

टीके की प्रतिक्रिया स्वरूप हमारा रोगरोधी तंत्र हरारत की  वजह लो ग्रेड फीवर की वजह बन सकता है लेकिन वेक्सीन फ्ल्यू रोधी होती है जिसमें फ्ल्यू की ही मृत विषाणु रहतीं हैं। अब भला डेड वायरस आपका क्या कर लेगा। 

(३) विटामिन एवं खनिज सम्पूर्ण हमें  दीर्घ स्वास्थ्य 

प्रदान करते हैं ?

तथ्य आपको डरा  सकते हैं हिला सकते हैं मिथ है यह 

भी। 

जर्नल "कैंसर रिसर्च "में इसी बरस प्रकाशित एक अध्ययन के अनुसार 

फिश आइल चूहों में कैंसर की वजह बनते देखा गया है। 

लेकिन कुदरती स्रोत से भले आप इसकी ज़रुरत से फ़ालतू डोज़ ही क्यों न 

लेलें कोई ख़तरा पेश नहीं होगा। 

(४) Cold weather makes you sick 

Studies have shown we may feel more cold symptoms ,real or imaginary ,when we are chilled ,but the temperature does not make us more susceptible to viruses .Studies have shown when shivering in a frigid room or stuttering in an icy bath ,people are no more likely to get sick after sniffing cold germs then they are in warmer climes .Scientists speculate that colds are more common in cooler months because people stay indoors more ,interacting more closely with one another and giving germs an opportunity to spread .

(५ )सिर में चोट आने के बाद मरीज़ को सोना नहीं चाहिए ?

बेशक तुरत डॉ. के पास पहुंचे लेकिन अक्सर ये खतरनाक साबित नहीं होती हैं। अपवाद तो फिर सब जगह हैं। एक ख़ास किस्म की हेड इंजरी में जिसमें ब्रेन -ब्लीडिंग होती है तथा मरीज़ कोमा में भी जा सकता है को लेकर यह मिथक शुरू हुआ था। सिर की आम चोटों से इसका कोई लेना देना नहीं है। 

मिथ या यथार्थ :

Truth be told

Mumbai Mirror Bureau

Medical myths that survive despite contrary research are dangerous. Get smarter with our facts-first guide.

Myth: Chewing gum stays in your stomach for seven years 

Fact: While it is true that many of the ingredients in gum, such as elastomers, resins and waxes, are indigestible, that does not mean they hang in our guts for eternity. Plenty of what we eat including recommended edibles such as fibre, is indigestible. However, the digestive system is a robust piece of organic machinery, and anything it can't absorb, moves along. Despite the stickiness and strange consistency of gum, it passes right through your digestive tract and into the toilet bowl. 

Myth: Reading in the dark or sitting too close to the TV ruins eyesight 

Fact: Dim light, or staring into the multicoloured tube at close range, can undoubtedly make your eyes work so hard that they hurt. However, there is no evidence that these practices cause long-term damage. The TV myth may have started in the 1960s, and at that time, it may have been true. Some early colour TV sets emitted high amounts of radiation that could have caused eye damage, but this problem has long been remedied, and today's TV and computer monitors are relatively safe. If you tend to sit so close to the computer or TV it hurts the eyes, it may be time to check for nearsightedness. 

Myth: Vaccines cause the flu 

Fact: While there is a possibility that our body can react to any shot with a low-grade fever, rumours that a flu shot causes the flu are not quite true. The flu shot does contain dead flu viruses but they are, as their name suggests, 'dead'. And a dead virus cannot be resurrected to cause a flu. 

Myth: Supplements make you healthier 

Fact: Really? Research suggests the reverse. In fact, an increasing number of studies say that vitamin supplementation may not only be ineffectual, but also hazardous to your health. A study published this year in the journal Cancer Research linked fish oil supplements with cancer in mice. On the other hand, there is no need to worry about overdosing if the 'good-for-you' compound is coming from real food, rather than a pill. Go natural, we say. 

Myth: Cold weather makes you sick 

Truth be told

Fact: Studies have shown we may feel more cold symptoms, real or imaginary, when we are chilled, but the temperature does not make us more susceptible to viruses. Studies have shown when shivering in a frigid room or stuttering in an icy bath, people are no more likely to get sick after sniffing cold germs than they are in warmer climes. Scientists speculate that colds are more common in cooler months because people stay indoors more, interacting more closely with one another and giving germs an opportunity to spread. 

Myth: You need to stay awake if you've had a concussion 

Fact: While concussions always merit medical attention, they are rarely severe or lifethreatening. Warnings to stay awake after a concussion grew out of a misunderstanding about a particular type of head injury that involves brain bleeding, where a lucid period is followed by a coma. However, this is uncommon and doesn't concern people with normal concussions. 

Myth: You should wait an hour after eating before you go swimming 

Fact: There is no special reason not to swim after eating. Sure, any type of vigorous exercise can be uncomfortable (although not dangerous) after eating a hearty meal, but for most of us whose waterfront dining experience includes fried chips and sandwiches, that is hardly a concern. And cramps can happen anytime, whether you've eaten or not.

Hungry? You're more likely to fight with spouse

Low levels of blood sugar can increase the risk of a niggling irritation with your partner turning into a blazing row according to a study suggesting a physiological basis for marital disharmony. 

Scientists have found that glucose levels in the blood can accurately predict whether someone is likely to feel angry enough with their spouse to secretly stick pins in a voodoo doll meant to represent them in psychological tests. People with low glucose levels were also more likely than individuals with high levels to blast their partners with loud noise if they had just competed against them in a game, according to a second experiment. 

The findings support the widely held belief that hungry people are more likely to be angry than well-fed individuals. They also provide a scientific basis for suggesting that food and diet may play an important role in aggressive tendencies in certain social situations where people spend a time together, whether at home, in schools or in prisons. 

"People can relate to this that when they get hungry, they get cranky. We found that being 'hangry' - hungry and angry - can affect our behaviour in a bad way, even in our most intimate relationships," said Professor Brad Bushman of Ohio State University in Columbus, Ohio. 

The three-year study involved 107 married couples who were assessed for their general relationship satisfaction to see how happy there were with one another overall. Over a period of 21 days, each couple monitored their blood glucose levels in the morning and evening and were given a voodoo doll and 51 pins, which they were supposed to stick in the doll when they were on their own depending on how angry they felt towards their spouse.

Sperms carry stress from dads to kids: Study

LONDON: Men may not only pass traits to their offspring, but some stress too! 


Stress alters the expression of small Ribonucleic acids (RNAs) in male mice and leads to depressive behaviours in later generations, a new research suggests . The mice show depressive behaviours that persist in their progeny, researchers said. 

In the study, Isabelle Mansuy, a neuroscientist at the University of Zurich, Switzerland, and her colleagues periodically separated mother mice from their young ones and exposed the mothers to stressful situations. 

These separations occurred every day but at erratic times, so that the mothers could not comfort their pups (termed the F1 generation ) with extra cuddling before separation. 

When raised this way, male offspring showed depressive behaviours, the study found. The F1 males' offspring, the F2 generation , showed similar depressive behaviours and metabolism disorders.
