Things you didn’t know about left-handers

Being left-handed has its advantages and disadvantages
Hitting your elbows while writing with a right-hander sitting next to you; a hand that becomes covered with ink when moved over the handwriting; a pair of scissors that cannot be held normally. Left-handed people often face clumsiness in their daily lives. But left-handers probably already know this. However, there are other things you may not know about left-handers. We will list them for you.

12 percent


Only 12% of the population is left-handed, but this percentage is slowly increasing. Although being left-handed has long been accepted in most countries, there are still countries that do not accept a person to be left-handed. Fortunately, this practice is becoming more and more accepted, and as a result, the percentage of people who embrace their left-handedness is slowly increasing. In 1860, it was even thought that left-handers had a pact with the devil.

Allergies


Are you left-handed and suffer from allergies in the spring? This is not surprising. The book “Cerebral Dominance: The Biological Foundation”, shows that left-handed people are 11 times more likely to be allergic to something. They are also 2.5 times more likely to develop an autoimmune disease.
More sensitive to migraines
The life of a left-handed person is not always a bed of roses. It also appears that left-handed people suffer from migraines twice as often as right-handed people.

Restless sleeper


We all move in our sleep, but it’s much more common in left-handed people. The phenomenon of periodic limb movements (PLMD) is much more common in left-handed people. PLMD is a disorder in which limbs move involuntarily during sleep. A 2011 study shows that 94% of left-handed people sometimes suffer from it, compared to 69% of right-handed people.

Wondering if there are also positives to being left-handed? Of course, you do! Discover them on the next page.


They’re smarter


Yes, being left-handed can also have its advantages. A 2007 study shows that left-handed people generally have a higher IQ. Unfortunately, we don’t know exactly how it works. To make the situation even more confusing, another study claimed in 2010 that it was exactly the opposite.

More left-handed men


A 2008 survey on left-handedness showed that men are more often left-handed than women. The researchers looked at data from 144 left-handed people and found that men are more often left-handed, to be precise: in men, we see it 23% more often than in women.


Best in multitasking


Data collected by the Illinois research consortium show that left-handed people are better at multitasking than right-handed ones. It also seems that left-handed people remember things better than right-handed people.

See faster underwater


We don’t really know how this discovery was made, but a neurologist apparently discovered that left-handed vision adapts more quickly underwater than right-handed people.

Language feedback


Sometimes, jokingly, we ask if someone can curl the sides of their tongue. Not everyone can do it, let alone left-handers. According to one study, only 62.8% of left-handed people manage to roll their tongues, compared to 74.8% of right-handed people.
