From threading a needle to opening a juice tin with an opener, the lefties life struggle is real. Lefties covering 10% of total world population may have little differently operating brains and bodies than those of right-handed people.
Lefties usually have unique and creative personalities. Surely, being a lefty can be frustrating at times (especially during the middle age), but it’s pretty cool to be a little different. So take a moment to pause and appreciate the plight of your cack-handed friends living in a right-handed world.
Let us look at some of the most common facts about being left-handed, and what it might really mean for your health.
- If your child is leftie the reason may be your pregnancy stress:
Studies show that fetuses of super-stressed pregnant women more likely touch their faces with their left hands, which are known to be signs of leftie. Many Swedish studies which support this theory. So, if you donÔÇÖt want your child to e leftie avoid stress during your pregnancy.
- Twins have high chances to be leftie:
A 1996 Belgian study found that about 21% of twins, both fraternal and identical, are left-handed. Which means left-handedness is about twice common in twins than in the general public.
- Left-handedness can be to a higher risk of breast cancer
Study published in the British Journal of cancer (2007), states that left-handers had a higher risk of breast cancer than right-handers, especially for cancer that occurred after menopause.┬á In fact, Left-handedness seems to be associated with some other physical health issues like low birth weight, weak immune system and low stamina.
- May up the risk of PTSD
Lefties are more likely to have unusual brain lateralization, which could affect the way their brains process fear and anger resulting in PTSD. Taking a research background from 2007 Scottish study we can say that left-handers were more likely to display symptoms of post-traumatic stress disorder after watching clips from a scary movie. So, if you are leftie think twice before watching any horror movie.
- Your rate of recovery can be quicker:
Research show if you are leftie you can recover faster from a stroke or other brain-related injuries. While we hope nobody has to go through anything as traumatic as a brain injury, itÔÇÖs nice to know that you could potentially have an easier time recovering. Reason? The cognitive functions are spread out in the brains of lefties, which mean that in theory, when you have a stroke, less of your cognitive functioning will be affected. I wish to be leftie now, Do you?
- Leftie can face some sleep problems:
There can be periodic limb movement disorder (PLMD) in lefties, which causes patients to involuntarily kick and jerk their arms and legs while sleeping. A study conducted by the University of Toledoin year 2011 states that left-handed people have significantly higher chances of having bilateral limb movements, indicating the potential for PLMD.
Overview: handedness doesn’t really matter
Of all the interesting facts about handedness, probably the most important one is that it doesn’t matter much at all. “The differences between righties and lefties are really rather subtle. Both righties and lefties are same.
Hopefully, we’ll have a better understanding of them soon. We shouldn’t assume much about people’s personalities or health just because of the hand they write with. And we certainly shouldn’t worry about lefties’ chances of success: After all successful personalities like and Aristotle and Barak Obama are left-handed.
