Holi is played in the Spring Season which is a period between end of winter and advent of summer. We normally go through the transition phase of winter and summer. The period induces the growth of bacteria in the atmosphere as well as in the body. When Holika is burnt, temperature of the nearby area raises around 50-60 degree Celsius. Following the tradition when people perform Parikrama (go around the bonfire/pyre), the heat coming from the bonfire kills the bacteria in the body and cleanses it.
This is the time, when people get the feeling of tardiness. This is quite natural for the body to experiences some tardiness because of change in weather from cold to the hot in the atmosphere. To counter this laziness, people sing Songs (Phag, Jogira etc.) with Dhol, Manjira and other traditional instruments.
Colours play vital role in fitness of human body. Deficiency of a particular colour could cause an ailment and can be cured when that colour element is supplemented either through diet or medicine. In ancient times, when people started playing Holi, the colours used by them were made from natural sources like turmeric, Neem, Palash (Tesu) etc. The playful pouring and throwing of colour powders made from these natural sources has a healing effect on the human body. It has the effect of strengthening the ions in the body and adds health and beauty to it.

Now a day, market is mostly flooded with synthetic colours and herbal colours are not available in adequate quantity. Synthetic Colours are also cheap but are very harmful to the all.

Composed of gas and dust, the pictured pillar resides in a tempestuous stellar nursery called the Carina Nebula, located 7500 light-years away in the southern constellation of Carina.
Taken in visible light, the image shows the tip of the three-light-year-long pillar, bathed in the glow of light from hot, massive stars off the top of the image. Scorching radiation and fast winds (streams of charged particles) from these stars are sculpting the pillar and causing new stars to form within it. Streamers of gas and dust can be seen flowing off the top of the structure.
Hubble's Wide Field Camera 3 observed the Carina Nebula on 24-30 July 2009. WFC3 was installed aboard Hubble in May 2009 during Servicing Mission 4. The composite image was made from filters that isolate emission from iron, magnesium, oxygen, hydrogen and sulphur.
These Hubble observations of the Carina Nebula are part of the Hubble Servicing Mission 4 Early Release Observations.
