What are "Heat Waves" ?
The India Meteorological Department (IMD) has warned of likely development of heatwave conditions over multiple states in the country.
A heatwave is declared when the maximum temperature over a location increases by 5 to 6 degrees from normal or rises above 45 degrees Celsius in the plains.
Over the hills, the threshold is 30 degrees Celsius.

Demand for convalescent plasma has grown steadily over the past one week in Gurugram with sudden spike in COVID-19 cases.
Blood plasma is a yellowish liquid component of blood that holds the blood cells of whole blood in suspension. It is the liquid part of the blood that carries cells and proteins throughout the body. It makes up about 55% of the body's total blood volume.
Convalescent plasma refers to plasma obtained from an individual who has recuperated from an infection.
During the infectious period, the individual's immune system would have mounted an attack on the foreign virus. By the time the virus is vanquished, the body would have developed ammunition specifically to beat the virus, which will be a type of antibody.
These antibodies are suspended in the circulating blood, and can be separated out from one of the components of blood - the plasma.
A donor can donate her plasma up to twice a week with a minimum gap of 48 hours, and a maximum of 24 times in a year in India.
A special medical technology called apheresis, using expensive equipment, is used to draw blood from the patient, separate the plasma out, and return the rest of the blood back into the body.
