Baldness gives unhappiness to a person. People feel it as a sign of getting old and the person feels that because of his baldness his looks suffer. People will do anything and go to any length to get a good crop of hair on their head. Worldwide hair loss treatment industry is worth $ 3.5 billion/year.

However, new scientific evidence suggests that infrared (IR) radiation in solar energy is transmitted through bald head and may help in repair of neurons, their generation, and stop or reduce the ravaging affects of Parkinson’s disease.

In all ancient civilizations whether Greek, Egyptian, Indian etc. and in various religions, baldness or shaven head was identified with philosophers, monks and priests. Some say that it was done to differentiate such people from common folks. Thus a person with shaven head wearing an ochre robe is normally identified as a Buddhist monk or a Sanyasi.

The  ancients understood the power of solar energy on the bald head and hence the practice developed. Thus it is possible that our ancient tradition of invoking Gayatri Mantra and practicing Surya Namaskar could be traced to the understanding of beneficial effects of solar energy radiation on human body.

Bald human skull allows 10% of incident IR radiation to pass through it. IR radiation which has wavelength of 750-1500 nanometers is not visible to the naked eye and is the source of heat. On the other hand visible radiation has wavelengths in the range of 450- 750 nanometers.

Around 50% of solar radiation falling on earth is in the IR range. Nature uses this radiation very effectively since it helps in producing wind, evaporating sea water to form clouds and produce rain and to help the neurons function effectively in brain.

How the IR radiation helps in neuron repair and regeneration is still not fully understood. Some scientists say that IR, since it is mostly heat, helps in increasing the brains temperature and hence the activity of neurons while others say that the mitochondria, the engine which provides energy to cells gets repaired and energized by it leading to neuron repair and generation. Nevertheless the beneficial effect of IR on brain is evident and has been shown in human and animal trials.

Infrared light therapy nowadays is also being used and promoted as a powerful and noninvasive treatment for patients suffering strokes, head injuries and as an eye treatment.

The penetration of IR radiation into human brains is quite shallow and attenuates within 2-3 cms of entering the brain tissue but the blood flow in the brain allows the regenerated and repaired brain cells to be transported to different parts of brains.

Why are neurons affected by IR radiation? A possible explanation could be that during their firing they produce a feeble radiation in the IR range and by principle of equivalence they react positively to it.

So bald people, rejoice that nature and especially solar energy will help you in improving your brain and provide happiness since a supple and powerful brain is necessary for creating happiness. The main thing is to sit in the sun for 10-15 minutes everyday. Not only will your brain become better but you will also get much needed vitamin D.

Train Your Brain By Following Good Habits Constantly

The researchers have created a model which shows that forming good (and bad) habits depends more on how often you perform an action than on how much satisfaction you get from it.

If you want to form good habits — like going to the gym and eating healthy — then you need to train your brain by repeating actions until they stick, a new study suggests.

The researchers have created a model which shows that forming good (and bad) habits depends more on how often you perform an action than on how much satisfaction you get from it.

“Psychologists have been trying to understand what drives our habits for over a century, and one of the recurring questions is how much habits are a product of what we want versus what we do,” said Amitai Shenhav, Assistant Professor at Brown University.

“Our model helps to answer that by suggesting that habits themselves are a product of our previous actions, but in certain situations those habits can be supplanted by our desire to get the best outcome,” Shenhav added.

For the study, published in the journal Psychological Review, the researchers developed a computer simulation, in which digital rodents were given a choice of two levers, one of which was associated with the chance of getting a reward.

The lever with the reward was the ‘correct’ one, and the lever without was the ‘wrong’ one.

The chance of getting a reward was swapped between the two levers, and the simulated rodents were trained to choose the ‘correct’ one.

When the digital rodents were trained for a short time, they managed to choose the new, ‘correct’ lever when the chance of a reward was swapped. However, when they were trained extensively on one lever, the digital rats stuck to the ‘wrong’ lever stubbornly, even when it no longer had the chance for a reward.

The rodents preferred to stick to the repeated action that they were used to, rather than have the chance for a reward. (IANS)
