Chennai:  23.11.2020 

The city is likely to experience heavy to very heavy rain as cyclone Nivar is likely to make landfall between Mamallapuram and Karaikal on Wednesday noon or afternoon. Rainfall of 6cm-10cm is expected. Monday will be generally cloudy with light drizzle as the weather system is too far away and it will start raining on Tuesday as the cyclone edges closer to the coast.

Villupuram, Cuddalore, Puducherry and Chennai are expected to have heavy rain when it starts to make landfall on Wednesday.

An IMD bulletin said a well-marked low pressure in the Bay of Bengal closer to the Tamil Nadu coast will intensify into a depression in the next 12 hours and will develop into a cyclonic storm in the subsequent 24 hours. It is moving at 18kmph speed towards the coast.

S Balachandran, deputy director-general of regional meteorological centre, Chennai, said, “Rain will start in coastal districts on Monday and will intensify step by step. On Tuesday and Wednesday, some areas on the coast will receive heavy rain and very heavy rain. Fishermen should not venture into the sea till November 25.” He also said there are chances of heavy rain to start in the city and its suburbs on Tuesday.

The well-marked low pressure is located 760km away from Chennai and 700km from Karaikal. It will skirt the coast of Sri Lanka and move northwest to hit the Tamil Nadu coast.

A Met official said the system is moving at a good speed and has been named as cyclone Nivar by Iran. Private weather bloggers hint that conditions such as wind shear, warm sea surface temperature and absence of dry air are in favour of the cyclone to intensify. However, the speed at which it will move and also develop can be a drawback, making it less intense.

The low pressure is fast turning into a depression, in 12 hours instead of the 24 hours forecast earlier. There is a 0.46inch thunderstorm in the sea where the low pressure is concentrated but probably because of its presence, it was a hot and rainless Sunday across the state.

The cyclone is likely to improve the rainfall deficit the city is facing this northeast monsoon. Chennai has received 477.4mm rainfall so far since October 1 against the expected 539mm, leaving a 11% deficit. Tamil Nadu has a 23% deficit with 242.6mm rainfall recorded so far against a normal 314.1mm.

Chennai: 23.11.2020 

Complaints of ear pain, infection and irritation have almost doubled over the past eight months in the city, say doctors. As more people are locked indoors, glued to computers and gadgets, they have also begun to overuse earphones.

Over the past months, doctors have been getting at least four complaints a day. And every time there’s an inquiry or a visit, the first question the doctors usually ask patient is how long they use earphones in a day.

Dr Thirunavukkarasu S, senior consultant - pediatric ENT and airway surgeon, Rainbow Children’s Hospital, said people often suspect that pain or infection in the ears is caused because of the entry of water. “But then I explain to them that the ear is self-cleaning. And tell them that by using earbuds or earphones for long hours the ear wax is pushed further inside leaving no space for it to come out. This causes pain.”

As classes have also moved online, several children are keep earphones on. They watch serials, movies gadgets and listen to loud music for more than 15 hours a day, without a break. This can cause noise-induced hearing problems.

Doctors said persistent use and blasting loud music can damage hair cells which help in transmitting sound waves to the inner ear. And once these cells are damaged it cannot regenerate and the person will end up having a permanent hearing problem and depend on hearing aids or implants.

“Sound levels beyond 60 decibels and prolonged hearing for over eight hours can be damaging,” said Dr Paneerselvam V R, senior consultant, ENT neurotologist, Promed Hospital.

Conversations in online classes reach a decibel level of 60 but can touch 80 to100 decibels when volume is increased to the maximum on earphones.

Dr Paneerselvam said those who have hearing problems must be more cautious and avoid listening to loud music for long hours.

Doctors advised people against using earbuds to remove the wax since ears are self-cleaning and using the buds could cause earaches.

Asked about the prevention of ear infections, doctors suggested using headphones instead of earphones because these provide a buffering space between the speaker and the ear canal. Listening to songs in open spaces can also help prevent ear pain. And after every hour or two a 15-minute break is a must.

People must also watch out for indicators such as a constant need to crack up the volume or hearing buzzing sounds as these are symptoms of loss of hearing. “If they experience any of this, they must consult a doctor,” said Dr Thirunavukkarasu.
