This includes thinking and such mental activities as well.  Foods have varying amounts of carbohydrates, proteins, fats, vitamins, minerals, and trace metals. These are basic components of food and should be in right proportions in daily diet for health and prevention of diseases. Diseases result from shortage of food, excess of food, as well as deficiency and excess of any of the above components of food.  Also, read Ways of eating idlis  Humans learned to cook food after fire was made using stones.

Know how immunity develops after coronavirus vaccine administration in a person!

-

 Coronavirus vaccine has come in and people are getting vaccinated worldwide against the dreaded virus! But there have been isolated cases of people getting infection despite the vaccine. There are certain things that one must know about the benefits and limitations of the vaccine to fully understand these cases. 

A few vaccines have been approved in different countries of the world against coronavirus. These include Pfizer, Moderna and other local vaccines such as in China and Russia. Studies have revealed that the vaccine efficacy is 50% after the first dose of the vaccine and 95% after the second dose of the vaccine. But the antibodies take 45 days to appear and hence the person who has taken the vaccine may still acquire the infection if he catches the virus in between.

Hence, if a person gets the vaccine and still contracts the infection, it could imply any of the following:

1.       It is possible in 50% of the people after the first dose of the vaccine if he comes in contact with the virus in the interim period.

2.       In 5% of the people, the infection may occur despite the vaccine after the second dose of the vaccine.

3.       The vaccinee may still get the infection if he has taken the second dose of the vaccine and 45 days post-second dose are not over.

4.       If the vaccine cold chain was broken before the dose was given to the person. Breaking the cold chain makes the vaccine unusable and ineffective. Safety is not hampered by it.

5.       If the vaccinee is obese and hence the production of antibodies in him or her is half that in normal individuals.

6.       For some unknown genetic reason when the vaccine may not take in a person. This is a theoretical possibility.

7.       If the viral dose is high and the antibodies produced in a person are ineffective to take care of those high viral load.

Hence, to avoid getting an infection after the two doses of vaccine, it is a must that the vaccinee should adhere to all the precautions of COVID-19 even after the second dose of the vaccine has been taken and for at least 45 days post-second dose of the vaccine. Hand hygiene, social distancing, and face mask-wearing should be followed even if one has taken the vaccine. Prevention is better than cure!

Color therapy-the ancient art of healing! Know the science behind it and its current status!

  Color as a form of therapy is not a new concept. In it, electromagnetic waves in the form of the visible spectrum (that we interpret as colors) are used to cure various body illnesses. It is an ancient mode of therapy that is being reinvented. There are attempts to elucidate its scientific basis and explanation. This would help to explore and discover newer dimensions of this old remedy. Color therapy (Chromotherapy) Newton talked about solid matter and moving objects while Einstein found out that mass and energy are dual expressions of the same universal substance. It is the vibration rate of its molecules that determines its form. When slow, it is physical matter and when the vibrations are intense it is energy. Thus, light is an energy and when it interacts with matter, color is formed. Each color has its own wavelength, frequency, and energy level. And human eye is adapted to see only this energy that has a wavelength between 380-780 nm. This is therefore, the visible spe...

 Covid-19 pandemic started in Wuhan in China. This was in December 2019. But China continues to state that though the first cases of Covid-19 were detected in Wuhan, it never originated there. But the world wants to know the true answer of origin of the virus and hence the pandemic that brought the world to a standstill. WHO is investigating this matter.  China and its denial of origin of coronavirus   China has been persistent in its denial of Covid-19 in Wuhan. It stresses that though the first cases were detected there, they never originated there. They claim that it came into Wuhan from somewhere else.  But the world feels that the wet markets are the source of the pandemic. Also, the other powerful countries of the world such as the USA blame the Wuhan Virology lab for the start of the virus and its spread to the outside world. WHO is investigating this matter. Initially, WHO was denied access of the lab but now they have been able to get inside and try to probe...
