THE AIR WE BREATHE •Molecules in the air include primarily nitrogen and oxygen as well as water, carbon dioxide, ozone, and many other compounds in trace amounts - some of these are naturally occurring while  others the result of human activity. •In addition to gases, the atmosphere contains extras such as smoke, dust, acid droplets, and pollen. •The composition of the atmosphere changes constantly and depends on the season, weather, time of day etc. WHAT CAUSES  AIR POLLUTION ? Most of the air pollution results from the burning of fossil fuels, such as coal, oil, natural gas, and petrol/ diesel to produce electricity and power our vehicles.  Carbon dioxide (CO2) is a good indicator of how much fossil fuel is burned and how much of other pollutants are emitted as a result. AIR POLLUTANTS  are of three types •Gases •Particulate Matter Bacteria and Viruses  COMMON AIR POLLUTANTS  ARE •Carbon Monoxide •Ground Level Ozone •Lead •Nitrogen Dioxide •Particulate Ma...

There has been tremendous controversy recently about the "Asymptomatic Patient" - who are they and can they spread Corona virus infection? To understand the terminology in its context, let us look at three different but closely related situations -  1.  The Mildly Symptomatic Patient - This patient of confirmed Covid-19 has mild symptoms like fever, occasional cough or mild breathlessness. They gradually recover without any specialized treatment.  2.  The Pre-Symptomatic Patient -  These patients have been recently infected, have currently no symptoms, but will gradually develop them. They can transmit infection during this incubation period. This is usually about a week from contracting the infection, but could be up to two weeks. 3.  The Asymptomatic Patient  - This is a confirmed case of Covid-19 who never develops any symptom. What makes this disease pursue a relentless and fatal path in some patients and leaves many practically untouched is still ...

Though swimming is a wonderful full body exercise, it can sometimes cause problems in the ears, a condition called  'Swimmer's Ears' . Due to the constant presence of water in the ears, and sometimes because of swimming in unclean waters of rivers and ponds  etc the ears get infected leading to 'Swimmer's Ears'. CAUSES OF ITCHY EARS Wax accumulation - The presence of wax in the ears, specially when it gets excessive or dry may cause the ears to itch Eczema and other skin problems - It must be understood that though the ear is a separate organ by itself the skin on the outside portion of the ear and ear canal is the same as skin elsewhere - so skin disorders like eczema, psoriasis can affect the ears as well Dandruff - dandruff from the scalp can enter the ear canal and cause intense itching - it needs to be treated aggressively Use of ...

A Hearing Aid is a device that amplifies sound and transmits it into your ears. PARTS OF A HEARING AID A traditional Hearing Aid will have the following components: Microphone - this picks up sound around you Amplifier - this makes the sound louder for you. Receiver - sends sound into your ear. The sound is louder TYPES OF HEARING AID  Depending upon the type and degree of  hearing loss , patient profile, ear anatomy, etc different types of hearing aids are prescribed. These commonly are: ITE - In The Ear - These are discreet and though visible they fit into the ear canal. Though preferred by patients on account of the fact they are practically invisible, the truth is that these hearing aids can only be offered to patients with a mild or moderate hearing loss. Unfortunately, by the time patients decide to use hearing aids their hearing loss is usually in the severe category and these hearing aids may not be adequate.
