It is interesting to note that the festival of Holi is significant for our lives and body in many other ways than providing joy and fun. We also need to thank our forefathers who started the trend of celebrating Holi at such a scientifically accurate time. And, also for incorporating so much fun in the festival.
As Holi comes at a time of the year when people have a tendency to feel sleepy and lazy. This is natural for the body to experiences some tardiness due to the change from the cold to the heat in the atmosphere. To counteract this tardiness of the body, people sing loudly or even speak loudly. Their movements are brisk and their music is loud. All of this helps to rejuvenate the system of the human body.
Besides, the colours when sprayed on the body have a great impact on it. Biologists believe the liquid dye or Abeer penetrates the body and enters into the pores. It has the effect of strengthening the ions in the body and adds health and beauty to it.
There is yet another scientific reason for celebrating the Holi, this however pertains to the tradition of Holika Dahan. The mutation period of winter and spring, induces the growth of bacteria in the atmosphere as well as in the body. When Holika is burnt, temperature rises to about 145 degrees Fahrenhiet. Following the tradition when people perform Parikrima (circumambulation or going around) around the fire, the heat from the fire kills the bacteria in the body thus, cleansing it.
The way Holi is celebrated in south, the festival also promotes good health. For, the day after the burning of Holika people put ash (Vibhuti) on their forehead and they would mix Chandan (sandal paste) with the young leaves and flowers of the Mango tree and consume it to promote good health.
Some also believe that play with colours help to promote good health as colours are said to have great impact on our body and our health. Western-Physicians and doctors believe that for a healthy body, colours too have an important place besides the other vital elements. Deficiency of a particular colour in our body causes ailment, which can be cured only after supplementing the body with that particular colour.
People also clean-up their houses on Holi which helps in clearing up the dust and mess in the house and get rid of mosquitoes and others pests. A clean house generally makes the residents feel good and generate positive energies.
