Why we have no cure for common cold yet and symptom difference with Flu and Pneumonia


Why we have no cure for common cold yet?

Common cold is a viral infectious disease of the upper respiratory tract that mainly affects the nose. With other health problems or already weak immune system, one may develop pneumonia also.
Over 200 virus strains are implicated in causing the common cold, with rhinoviruses being the most common. These viruses stick to the cells at the back of your throat. They quickly reproduce from the cells to spread to neighboring cells in the rest of the tract.

And while we can treat the symptoms of cold by isolating the virus like other diseases, we cannot cure it, because of their different types and rapid mutation property of each of those types. Thus, in the time it takes to develop a vaccine, it will no longer be useful to us.

Symptom difference with flu and Pneumonia?

Apart from acute viral respiratory illness being a common symptom, the basic difference between below diseases are:

Common cold: Less severe symptoms, runny nose, sore throat

Influenza (flu): severe symptoms, (less likely to have a runny nose), fever, chills, fatigue, muscle aches

Pneumonia: severe symptoms, sharp chest pain with inhalation, excessive sweating, increased breathing and heart rate and light blueness around the mouth and lips.

Why a slow song seems fast just after waking up?


Have you ever played a song right after waking up? If no, then please do. You will certainly agree with the title of this post.

As a matter of fact, after gaining access to media devices in my childhood, I observed this strange thing for days..later forgetting the whole thing.

So how’s this possible? I have two speculations in queue,

Speculation 1:

Recall the time when you heard that song first time, the speed you heard that time can be compared with nothing, but many repetitions later, a default speed is saved.

And it is natural for the brain to reset and go through a mental checklist every time you wake up from sleep.

Now when you wake up, although the song is in your memory but the timbre, rhythms, pitch etc are not yet fetched instantly. Hence our brain sort of behaves like its hearing few wave parts for the first time. And till the time it fetches it node by node, the wave line passes, making it to lose the details or in other words the song appears faster.

Incidentally, instrumentals seems less faster thus supporting above speculation.

Speculation 2:

It has been known that humans recall fatal events in ‘slow motion’ due to a reverse of this phenomenon i.e.; more details recalled to increase survival chance or slower overall recall because of a fixed recall speed.

The ‘grogginess‘ experienced upon waking might play a part as well. Thus we can blame evolution over here 😛

Another example of this is, sitting down and relaxing music seems faster, but if you go for a jog or begin any strenuous activity, the speed decreases. Thereby supporting this speculation.

But no matter what the speculations are, listening to our favorite songs right after waking up takes refreshments to another level.

so Happy listening 🙂

Why clothe particles gets stuck in belly button?


Many times you must have observed some sort of fuzzy substance stuck in your belly button.  The term is belly button lint, my friend. But why it is caused and why only near the belly button.

Well the credit goes to research done by Austrian chemist Georg Steinhauser.
As per him, firstly, the hairs around the navel have very minute scales that act a bit like hooks that latch onto clothe fibers.

Then secondly, those hairs tend to grow in circular patterns around the belly button, leading to the optimize the collection.

Steinhauser tested his hypotheses by shaving his belly. He learned that shaving the belly does indeed lead to a lint-free belly button.

However some also think that rubbing of navel hairs and clothing contributes to a build-up of static electricity, resulting in the collection of clothing fibers and to a lesser extent, dead skin cell. But no solid grounds for that yet.

Healthy food substitutions for healthy lifestyle

Healthy diet

In recent times, people are making good effort to maintain an active and health-conscious lifestyle. So as to stay out of trouble for the long run. Of which a healthy diet is very crucial.

Usually, we’re always looking for ways to make our favorite foods healthier without sacrificing flavor. So below is the compiled list of 11 substitutions, (centered over Indian taste) having tasteful swaps.

1. Digestive biscuits over regular biscuits

These digestive counterparts are a clear winner over regular biscuits, in terms of health.  They ares not too sweet but with a faint salty aftertaste. Every bite feels delight, toasty and fibery.

Note: Oats and Ragi flavored Nutri choice biscuits have been labeled as ‘diabetic friendly’.

2. Canola oil over regular Cooking oil

Though as per Indian cuisine, Oils which can be used for roasting, deep frying etc. But oils with above properties which are low in saturated fats and having a healthy ratio of your “good” and “bad” cholesterol can be a good substitution for regular cooking oils.

And among many such oils, Canola oil tops the list.

A very elaborated description is provided at Self.com.

3. Dark chocolate over regular chocolate

While this is not really an alternative to chocolate, it is the best way to satisfy a chocolate craving with the real thing, but minimizing calories.  Choose the highest percentage cocoa that you can, as these contain the most beneficial antioxidants.

Note: the darker the chocolate (aka the higher % of cacao), the less sugar will be in the bar.

4. Fig bars over regular Cookie

These cookie-like treats are healthier than most homemade or packaged alternatives. Usually fig bars have 90 calories and 1 gram of fat compared to two homemade chocolate chip cookies at 120 calories and 14 grams of fat.

5. Skimmed milk for regular Milk

Skim milk is much lower in calories than whole milk — containing 90 calories per cup vs. 150 calories in whole milk — but provides about the same amount of protein, vitamins and minerals as whole milk. Whole milk contains saturated fat and dietary cholesterol, while skim milk provides just negligible amounts of these nutrients.

6. Brown rice for white rice

When white rice is processed, the “brown” bran layer gets stripped away, cutting out essential nutrients (like fiber). Opt for brown rice for a fuller nutritional profile.

7. Whole-wheat flour for white flour

In virtually any baked good, replacing white flour with whole-wheat can add a whole new dimension of nutrients, flavor, and texture. Because whole-wheat includes the outer shell of the grain, it also provides more fiber, which aids in digestion and can even lower the risk of diabetes and heart disease.

If you are not sure your family will embrace whole-wheat pasta or flour? Mix it in with white to get them adjusted. Or use semi-brown rice (as shown in above pic) your family won’t even notice. Also same goes for Pasta as well. Prefer whole wheat pasta over regular white paste.

Note: Whole-wheat pastry flour is less dense and works well in softer products like cakes and muffins.

8. Dark leafy greens for typical lettuce

All greens are not created equal. Darker greens usually mean more nutrients like iron, vitamin C, and antioxidants. Sorry, iceberg’s just not cutting it anymore—go out and get some grown-up greens.

9. Whole-wheat bread for white bread

You’ve heard it all before, but we can’t forget to mention this one. Whole-grain wheat beats out processed white with a complete nutrition profile and better flavor and texture.

10. Popcorn for potato chips

Lower in fat, natural popcorn without pre-flavored seasonings is a great snack alternative to replace those oily, super-salty potato chips. Try made-at-home flavors by adding cinnamon, chili powder, or Parmesan.

11. Olive oil for butter

When you’re about to stir-fry your favorite vegetables, sauté in oil instead of butter to stick to your vegan diet. Given image is of a popularly used Olive oil spray.

Why do we feel sleepy in the afternoon?

Boring afternoon

I often feel tired and lazy between 2:30 pm to 4 pm in office. A task that takes five minutes in the morning starts to take fifteen minutes in the afternoon.
It becomes especially difficult if you have a meeting during this time, since as per my current position, I cannot postpone it 😛 .
So as usual, I researched it a bit and found out that its more common than I think.

:> Why ?

Just like most of the bodily activities are cyclic. Means there is a rhythm our body follows (technically known circadian rhythm). If you’ve not completed your usual quota of sleep the previous night then these dips can be even more intense.
On the other hand, having enough sleep can reduce the intensity of such dips.

[Other] reasons may include: 

Heavy lunch: in case of heavy lunch, body extracts extra energy from your body to digest, which in  turn reduces the overall quota.

Schedule change: In case of any schedule change like you have started jogging/gym in the early morning (or any other physical session), you will feel dip. Since your body did not adapted to this change yet. Though it will, depending on your workout sessions.


Heuristic naps: Since childhood, have been taught to sleep in afternoon, so that our parents could sleep peacefully 😛 . Maybe this schedule has caught on.


Boring work: It seems this reason is for me these days. The kind of interest you show in your work is inversely proportional to dip you feel.
Now you can think, why a new GOT episode you can watch even in late hours and why you can’t create a PPT in afternoon. Hell, I am getting bored just after thinking it :/

:> You have stated reasons but not yet answered why the rhythm itself exists ?

Reason for this is that human beings are bi-phasic (physically designed for two sleeps a day), with two major bodily rhythms (homeostatic sleep drive and circadian arousal) which pull us in different directions in terms of staying awake or sleeping, but they fascinatingly align in the middle of the day to create a ‘nap zone’.

This bi-phase could have evolved during our evolution. When humans were just plain wild hunters, they were able to get only few preys during afternoon since animals were not in the open (maybe due to another hunting predator or scorching heat in that time period etc). Thus they both might have decided to rest instead.

:> Ok, so how to overcome that ? Give both temporary and permanent solution.

A given solution directly depends on the cause of this dip.

If its meal, eat light.
If its workout schedule change, have patience, it will get sorted out by itself.
If its boring work, well you know what to do… 😛 . Just kidding, its true that given assignment is boring. But that’s not all. If there is one reason of why you do not like your job, then there must be several others, of why you do. You just need to find out 🙂

Saying that, below are the generic solutions one may try…


Usually, people overcome this dip by having a coffee or something sugary. However, this is not a good idea as a little while later your energy levels may dip even further. Also, as we all know coffee works around 45-60 mins later consumption. So if you are going for it, go sooner.

As a catalyst, you can go for a five-minute walk in the sun (if you have that kind of spacesuit 😛 ).


Sleep tight. Also don’t take 8 hours for the sake of taking 8 hours of sleep. Sleep as much as you need. Sleep early if you don’t want to curse your alarm clock. I know its easier said than done, but you need to plan the night first if you want to plan the day.

And if all else fails, take out your mobile, make it silent-vib mode, then take a 20-minute nap wherever you feel comfortable like a Panda 🙂 .
