Science behind eastern Hindu culture

Among all the religions the Hindu religion is considered to be very old. Here we have different culture values and also different responsibilities that really makes us feel proud and happy. We do lots many of the practices in the name of our sansar tradition. Knowingly or unknowingly we do all of this things for our own benefits yes its true. Researched have researched for this type of the things and activities that the eastern Hindu people are doing from thousands of years back in the name of the culture and traditions and the result they found were amazingly unexpected.
Most of the eastern Hindu people a vast majority from India and Nepal bow down their head in front of their elders the scientist researched on this activity and found that when they bow down head it helps to have a good blood circulation through out the body and in the same way it also helps to have good flow of blood from the arteries and have a sound body blood circulation. In the same way the next thing that the people do is they join their both hands to do namaskar, meaning its nice to meet and see them and the researchers have found out that the both fingers of the hand act as a pressure point that helps to stimulate the brain harmone which keeps the memory of that person to whom the namaskar is done is remembered for a long time by the brain. In the same way when the Hindu visit to the temple they put a red tika( powdered) on their forehead this helps to trap the positive energy from the surrounding also it helps to attract the focus of others for that person as red tika possess a strong attractive power. The woman also puts a tika on her forehead due to this reason. The next thing is the married woman put sindur(A mixture of lime,mercury,silica) on the top of her forehead that helps to maintain a good blood pressure as well as it helps to stimulate the sexual harmone this is the reason that the widow women are forbidden to wear sindur on her forehead as the eastern Hindu society is a male dominated society.
