Weather Office to Issue UV Advisories in New Delhi

The India Meteorological Department (IMD) announced that it will be issuing ultraviolet (UV) rays advisories at 10 locations in New Delhi.

The India Meteorological Department (IMD) announced that it will be issuing ultraviolet (UV) rays advisories at 10 locations in New Delhi which will allow the citizens in the national capital to find out the dose of UV rays that they are exposed to and take the necessary precautions to protect themselves from sunburn.

Invisible UV rays are emitted by the sun and overexposure to them is said to be the major risk factor for most skin cancers.

About Skin
Skin types can range from oily to dry, extreme dryness accompanied by rashes and itching can often denote the presence of a skin problem or skin disorder.

The weather office has recently launched the UV Index service for Pune and would launch it in Delhi by October. The UV rays readings will be displayed on LED screens at 10 locations in Delhi along with the temperature and humidity.

The Pune based-Indian Institute of Tropical Meteorology (IITM) will install Pyranometers at 10 places in Delhi to calculate the UV-Index, which will be measured on a scale of 1 to 10.

"Any reading between 1-5 is considered safe for Indian skin while limit between 5-6 is low risk. Reading between 6-8 is medium risk, while 8 and above falls in the category of high risk," Gurfan Beig, SAFAR programme director at IITM, told IANS.

Cyanosis - Causes, Diagnosis and Treatment
Cyanosis is the bluish or purplish discoloration of the skin and mucus membranes due to lack of oxygen in the blood. Cyanosis can occur at any age, but is particularly prevalent in babies born with congenital heart defects.

The facility is part of the SAFAR (System of Air quality Forecasting and Research) monitoring stations - India's first air quality prediction system of monitoring stations - that were put in place ahead of the 2010 Commonwealth Games.

"The instruments have been acquired from a US-based company and each costs around Rs. 15 lakh. They will measure UV rays that can cause skin cancer over prolonged exposure," Beig said.

Foods that are Bad for your Skin
Hydration, sebum formation and skin acidity determine the skin condition. Along with aging and environmental factors, diet too influences skin condition.

The UV-Index for India was developed by the scientists of the ministry of earth sciences after extensive research based on an analysis of the long-term atmospheric ozone data. It also follows the guidelines laid down by the World Health Organisation (WHO) on the UV rays.

"The UV-Index will be displayed along with the other parameters like temperature, humidity and pollutants on the LED screens already put at 10 places across the national capital," Beig said.
