GENEVA: A yawn is a spontaneous act. During this time, the eardrums elongate and the eyes shut firmly, making them watery.
It usually arises either prior to or following sleep. Also, it is believed to be a sign of being worn out or bored.
Not to mention that yawning is communicable to people and animals. Even babies do yawn in the womb.
Here are some of the most interesting facts about yawning:
- Yawning is considered the sign of tiredness, however, academics claim that while yawning, the heart tempo increases rapidly, which connotes that this can be a sign of attentiveness and not sluggishness.
- Moreover, you can also have this after doing workout as this would insinuate that your body switches from high energy to low energy. Nevertheless, people may often yawn while shifting physical states.
- Some studies opine that it could be a function of breathing. Yawns are more likely when the blood requires oxygen as it triggers a large intake of air and a boosted heartbeat, which, in turns, pumps more oxygen through the body. It clears out toxins from the blood and gives a fresh supply of oxygen.
- Do you know that yawning might cool the brain? Well yes, you have heard the true bit! When the jaw widens, it escalates the blood flow throughout the body particularly face and neck, which cools down the brain.
- We often wonder that when we see other people yawning, why we start up doing the same? Some historians believe that before humans communicated vocally, they may have used yawns to convey their message and watchfulness to others.
- Also, younger people are more likely to catch a yawn when compared to oldies. However, if you yawn too much, then it might be the symptom of mounting sleep or brain chaos, heart attack or troubles with the aorta.
Digital revolution: Can social media affect school grades?
BERLIN: Social media penetration gets to everywhere. Due to its hype and craze, youngsters tend to adhere to their laptops and phones so as to be connected with the online world.
In such, investigators from Germany set out to know the impacts of using social networking sites such as Snapchat, Facebook and Instagram on the academic performance of teens.
So as to look into this, Professor Markus Appel from the Julius-Maximilians-Universität Würzburg (JMU) in Bavaria, Germany and Timo Gnambs from the University of Bamberg have gone through some 59 studies harboring the link amid social media use and academic performance.
The studies comprised on approx 30,000 young people around the world.
Their findings suggest that those kids, who use social media so as to discuss apropos school related matters, have been reported performing slightly better.
On the contrary, those, who use Instagram while studying, log into others social networking sites post or send messages frequently, upload snaps and their activities, tend to perform somewhat worse as such practices trigger distraction when they do homework.
Maintaining that such sites could potentially impact its users non-constructively, academics further reiterate that parents should keep a watchful eye as to know in which activities their kids are involved when it comes to use social media.
Besides, they should inject variety in their activities (such as playing, social networking, studies, physical activities etc) as too much of anything is harmful.
The faster you eat the fatter you get!

KARACHI: People looking to shrink waistlines may want to adopt three simple eating habits to help them get there. A study tracking 60,000 people monitored eating speed and their evening meal time appeared to be significant factors in the struggle to lose weight.
Specifically, eating more slowly, avoiding snacks after dinner, and not eating within two hours before going to bed were all linked to weight loss.
The people were asked to report the speed at which they ate as fast, normal, or slow. The researchers found those who ate at normal speed were 29% less likely to be obese than fast eaters. The findings for slow eaters were 42% less likely to be obese.
Other habits the researchers looked at —including eating or skipping breakfast, and how much sleep— had no significant impact on weight.
A dietitian nutritionist and health psychologist maintained: “When you tend to eat quickly, you may miss out on your body’s cues for satiety, or fullness, and end up eating more. Natural slow eaters may be attending to their body’s cues for filling, and eat a more appropriate portion during each eating occasion”.
The study concludes that changes in eating habits can affect obesity, BMI and waist circumference. If you tend to be a fast eater try practice mindful eating, in which you consciously pay attention to each bite of food you put into your mouth and notice your thoughts, feelings, and sensations.
Asthma and pregnancy: What is the link?
SYDNEY: Asthma is a respiratory condition that affects lungs, resulting into mounting breathing troubles. It is now considered a common ailment as it is getting widespread rapidly due to environmental pollution.
Believe it or not, but a latest research has discovered a strong association between asthma and infertility.
According to the details, some specific prescriptions for asthma (particularly the quick healing medications) could potentially harm women’s aptitude to conceive.
For carrying this study out, academics have been through the records of over 5,600 preggos in the initial phase of their pregnancy.
All of the participants were from Australia, New Zealand, Britain and Ireland, who expected their foremost child.
Their outcomes revealed that those females, who took up quick asthma relievers, have been reported with having complications when it comes to fall pregnant.
It is pertinent to point it out here that those ladies take more than a year to conceive and the odds are up to 30 percent high.
It is to be noted that short-acting asthma preventers provide abrupt relief from the uncomfortable symptoms, whereas long-acting asthma relievers try to control the condition gradually.
While supporting their up shots, the study senior investigator Luke Grzeskowiak from the University of Adelaide held that besides affecting lungs, asthma also triggers inflammation in any part of the body such as the uterus, which, in return, affects the health of eggs in the ovaries.
