 Sleep is perhaps the single most effective thing that we can do each and every day to reset the health of our brain and our body. By understanding a little bit more about what sleep is we can get the chance to improve both the quantity and quality of our sleep.  What is sleep? Well sleep at least in human beings is subdivided into two main types. Non REM (Rapid Eye Movement) Sleep. REM Sleep Non-REM Sleep: Non REM sleep is further subdivided into 4 separate stages: Stage 1: Awake/Light Sleep Stage 2: Light Sleep Stage 3/4: Deep Sleep As we go into the light stages of Non-REM sleep our heart rate starts to decrease, your body temperature starts to drop and your electrical brain wave activity starts to slow down but as we move into deeper Non-REM sleep that is the stages 3 and 4, all of a sudden the brain erupts with these huge big powerful brain waves. The body gets recharged in terms of its immune system, we also get this beautiful overhaul of our cardio-vascular system and u...

 Many of us like to start our day with a cup of coffee and perhaps end the day with a glass of wine or some other kind of alcoholic drinks . But it turns out that these two substances alcohol and caffeine can have surprising impacts on our sleep.  Caffe ine: Let's start with caffeine, Caffeine is a kind of drug that we call the psycho-active stimulu s and everyone knows that caffeine can make you more alert and can wake you up but there are at least two additional hidden features of caffeine that some people may not be aware of. 1. The first is the duration of action of the caffeine. Caffeine for the average adult will have an effect for about 5-6 hours, what that means is that after about 5-6 hours   50% of that caffeine that you had is still circulating in your system. Caffeine has a quarter-life of about 10-12 hours. In other words, let's assume that you had coffee at 2 pm in the evening, it could be possible that almost the quarter of that caffeine is still swirling ...

Good night sleep is incredibly crucial for our health, it is as important as eating healthy and exercising.  Let us first consider some of the points to understand why sleep is that important for us. Poor sleep can link to higher body weight. In fact, short sleep duration is associated with an increased risk of weight gain and obesity in both children and adult.   Poor sleep affects hormones that regulate appetite. Those who get adequate sleep tend to eat fewer calories than those who don't.  Good sleep can maximize problem-solving skills and enhance memories. Poor sleep has been shown to impair brain function. Long sleep has been shown to improve many aspects of athletic and physical performance. Sleeping less than 7-8 hours per night is linked to an increased risk of heart disease and stroke. Sleep deprivation can cause prediabetes in healthy adults in as little as 6 days. Many studies show a strong link between short sleep duration and type 2 diabetes. Poor sleepi...

 How many schools do we have in India? We have 1.5 million schools in our country, yes 15 lakh schools and China just has 2.5 lakh. A country which is more populous than ours and is about three times our size China has only 1/6th of our schools. And when it comes to learning, Chinese kids are among the top 5 globally and Indian kids, unfortunately, they are in the bottom 5. More than 50% kids in India cannot read fluently and cannot do basic addition.  As a country we have one of the largest footprints of schools and one of the deepest learning crisis. Experts say that our learning crisis is linked to our footprints and so India needs to shut down half of its government schools. If we want to improve education in India, not for a few but for all of our kids we really need to shut down 5 lakh government schools in the country.  The picture above shows exactly what a government school looks like in the rural India, it has 45-50 kids and perhaps 2 classrooms, electricity and...

  Rana Ayyub is an Indian journalist whose work has exposed government corruption and human rights violations, and over the years she got used to trolls and controversies around her work but none of them have prepared her for what she faced in April 2018. She was sitting in a cafe when she saw it for the first time, a two minute twenty second video of her engaged in a sex act. She could not believe on her eyes because she never made a sex video but unfortunately thousands and thousands of people believed it was her. Ayyub said that sex is so often used to demean and shame women especially minority women who dare to challenge the powerful men, which she had done in her work. The fake sex video went viral in just 48 hours, all of her online accounts were flooded with screenshots of the video, with graphic rape and death rates, and lots and lots of abusive messages. An another online post suggested that she was available for sex and her home address and cell phone number was spread ac...

Time Travel  has been one of the most exciting topics for the Science Fiction movies since decades. In such movies we see that people sit in some sort of vehicles and they travel into time and reach to the past or future, full of adventures. But is this really possible? Can we travel into time? According to most of the scientists it is not possible with the best of physics or technological knowledge but some still believe that is possible.  What is time? According to Einstein's Theory of relativity time is relative, it is an illusion, it can vary for different observers depending on their speed through space and not constant as it is believed by many of us. Einstein theory of special relativity says that time slows or speeds up depending on how fast or slow we move relative to something else. This theory also explains the Twin Paradox, that says if one of the twins travels through space with the speed of light while the other twin being on earth, then the one who traveled spac...

We all live  in a world that is full of mysteries, many a times we do not have any scientific explanation to the things that are happening around. We encounter incidents that make us believe in some supernatural powers even if we do not want to. Parallel Life, Parallel Universe, Time travel and many more are some of the phenomena that the world has encountered in real and have evidences but it is still hard to believe in these and we do not have any scientific explanation to them, these are beyond our science. Parallel life is one of them and many of us may or may not have heard about it. Parallel life actually means that an individual lives exactly the same life that was lived in the past by some other individual after his death. They have the same qualities, same attitude and even same kind of death. This is really shocking and most of us may not believe in this but it is true. There are many evidences to prove this, so let us look at some of these: 1. Abraham Lincoln and John ...
