SCIENCE BEHIND SUPERSTITIONS
It is really surprising that they could judge the reasons for infertility and knew at that time that avoiding certain circumstances should significantly improve the likelihood of conception by decreasing attrition to the active genes controlling reproductive processes.
There are certain major contributing factors :
1. Biological problems with organic defects/disorders
(ex. Tubal Problems, Ovulation Disorders ,Uterine Tissue Endometriosis )
2. Geographical environment
(Excessive or insufficient availability of certain minerals or vitamins
in food ,water & breathable air)
3. Live Style ( Smoking, Occupations, Stress, Obesity)
Consuming well water contaminated with high levels nitrates, chemicals or bacteria is particularly dangerous for pregnant women can cause miscarriages in some women. It has been proved chemicals of pesticides like nitrites in food and well water, and chlordane in breathable air are potent inhibitors of fertility.
Our Ancestors would have also felt that certain occupational environments need a break to get conceived.
Further they thought pilgrimage , the tour to God places would get the positive factors like necessary vitamins and minerals which are unavailable locally and that are the most important in terms of fertility and preconception , apart from inculcate some discipline so to avoid the negative factors like smoking and consuming alcohol - as smokers sperm count is 15% lower than non smokers / have more abnormal sperms and alcohol consumption reduces 50% conception.
And no one can deny that Obesity and excess fat may also cause infertility by blocking the reproductive tract which can be managed by body fitness and having balanced diet - more protein and less fat.During pilgrimage the excess calorie is also burnt out while walking and claiming steps to reach the holy places and avoiding non vegetarian diet, the chance of eliminating this factor can’t be also ignored.
