Water intake keeps disease away

With the summer fast approaching, let us be prepared to fight the heat with a bottle of pure drinking water.

Most people drink water only after the throat becomes parched and tongue turns dry. But by then, dehydration has already set in and it does not help if one consumes sugary beverages, say doctors.

These beverages do not provide the nutrients the body needs at that time.

Our body is made of 70 per cent of water. It is needed to digest food, and for smooth functioning of muscles, nerves and joints. Water flushes out toxins through the kidney and keeps the skin supple and soft. You should make it a habit to drink two-and-a-half glasses of water after brushing your teeth in the morning and 200 ml of water before going to bed at night.

Drinking a glass of water every two hours activates the gut. Anybody over the age of 20 years needs 10 glasses of water. That is about 2.5 to 3 litres. Without water the skin loses its elasticity and blood becomes thicker.

Cells require water to carry on their work. We advise diabetics with renal problems to reduce water intake if their kidney function is impaired. The body loses water through sweat and expiration.

Drinking soda with salt in summer helps replace the electrolytes that we lose through sweat. In summer, the kidney conserves energy by producing less urine but water continues to be lost through sweat.

People with normal health should consume anywhere between 8 and 12 glasses of water every day. The intake should be more when they exercise.

Symptoms of dehydration

What do we have to look for? Symptoms of mild dehydration include sore throat, dry cough, burning sensation in the stomach, muscle cramps, fatigue, dry skin, headache, cold feet and hands, a hoarse voice, flushed skin, loss of appetite, dizziness, chronic pain in joints and lower back pain. A strong odour and change in urine colour is another sign of dehydration.

Severe symptoms are difficulty in swallowing, delirium, numb and shriveled skin, sunken eyes and blurred vision, clumsiness, stumbling, pain while passing urine and muscle spasm.

But doctors also warn that there are medical conditions when patients are not advised water intake. A patient with congestive heart failure is already drowning in his own fluid. His feet are swollen and the body is bloated. He cannot lie down because of the fluid overload. Such persons are advised to consume less water as body loses capacity to get rid of un-required water.

Such patients are put on diuretics to ensure that they get nutrient supplement.

Innovation - The Japanese Soap Factory Story

A Japanese soap factory had a problem: they sometimes shipped empty boxes, without the soap inside. This was due to the way the production line was set up, and people with experience in designing production lines will tell you how difficult it is to have everything happen with timings so precise that every single unit coming out of it is perfect 100% of the time. Customers who come all the way to the supermarket would end up buying someone else’s product. Understanding how important that was, the CEO of the soap factory got the top people in the company together and they decided to start a new project, in which they would hire an external engineering company to solve their empty boxes problem, as their engineering department was already too stretched to take on any extra effort. The project followed the usual process: budget and project sponsor allocated, RFP, third-parties selected, and six months (and $8 million) later they had a fantastic solution — on time, on budget, high quality ...

OOPS Concept explained by Steve Jobs

Would you explain, in simple terms, exactly what object-oriented software is?
Objects are like people. They’re living, breathing things that have knowledge inside them about how to do things and have memory inside them so they can remember things. And rather than interacting with them at a very low level, you interact with them at a very high level of abstraction, like we’re doing right here. Here’s an example: If I’m your laundry object, you can give me your dirty clothes and send me a message that says, “Can you get my clothes laundered, please.” I happen to know where the best laundry place in San Francisco is. And I speak English, and I have dollars in my pockets. So I go out and hail a taxicab and tell the driver to take me to this place in San Francisco. I go get your clothes laundered, I jump back in the cab, I get back here. I give you your clean clothes and say, “Here are your clean clothes.” You have no idea how I did that. You have no knowledge of the laundry place.  May...

The truth behind whitening lotions and creams

Let's face it -- the average Indian is obsessed with a fair complexion. Most dusky Indian beauties would give an arm and a leg to acquire pasty white skin, which we refer to as 'gora-chitta'. It's quite sad to see fresh, smooth-skinned (albeit dark) people ruin the texture and glow of their complexions by using every possible cream, lotion, soap, serum, face pack and what-have-you to become fair. The only ones benefiting from this craze are the fairness product companies who are laughing all the way to the bank. Don't get me wrong -- there are chemicals which work and there are ways to get rid of unwanted pigmentation, but you need to have the correct knowledge of what's good for you and what's not. Check out the ingredients on your fairness product package and read on to get the low-down on what works and what doesn't: 1.Hydroquinone: This is one of the most effective whitening compounds known today. However concentrations used matter immensely and in...
