Discover the Fascinating World of Left-Handed People: 10+ Surprising Facts

Left-handed people are truly remarkable and deserve recognition. Let’s delve into some intriguing facts about left-handers that may not have crossed your mind:

Comprise Approximately 12% of the Population

Globally, about 12% of people are left-handed, with 87% being right-handed, and 1% ambidextrous. This percentage is slowly rising as society becomes more accepting of left-handedness. Surprisingly, there were times when left-handed children were forced to become right-handed. In the 1860s, only around 2% of the population was left-handed. This 12% figure varies by country and gender.

National Left-Handers Day

August 13th is celebrated as National Left-Handers Day. The day also aims to raise awareness of the challenges that left-handers encounter in a right-handed world. It was first established in 1992 in the United Kingdom by the Left-Handers Club.

Five Left-Handed Presidents

The Oval Office has seen its fair share of left-handed leaders, including Gerald Ford, Jimmy Carter, Ronald Reagan, George H. W. Bush, Bill Clinton, George W. Bush, Barack Obama, Donald Trump, and Joe Biden.

Left-Handed People Might Be More Intelligent

Left-handers have unique brain organization, allowing them to process verbal information using both hemispheres. In contrast, right-handers have a more specialized brain division, with the right hemisphere handling visuospatial processing and the left hemisphere managing verbal processing. This flexibility gives left-handers an edge in processing information, leading to potentially higher intelligence levels compared to right-handers.

Faster Stroke Recovery

Strokes affecting the left side of the brain can disrupt language abilities. Approximately 95% of right-handers have their language centers in the left brain, while only 70% of left-handers do. This disparity means that more left-handers can recover their language skills after a stroke.

Prone to Allergies

Research shows that left-handed individuals are 11 times more likely to suffer from allergies than their right-handed counterparts. They also face a higher risk of autoimmune disorders such as ulcerative colitis and rheumatoid arthritis.

Athletic Advantage

Left-handers enjoy a distinct advantage in certain sports like fencing, boxing, tennis, baseball, and swimming. Right-handers are more accustomed to competing against fellow right-handers, making it challenging when facing left-handed opponents. For instance, a baseball batter might struggle when confronting a left-handed pitcher. This phenomenon is particularly noticeable in tennis, with approximately 40% of top players being left-handed.

Increased Susceptibility to Migraines

Studies indicate that left-handed individuals are twice as likely to experience migraines compared to right-handed individuals.

Better Multitaskers

According to a 2008 study by the Illinois Research Consortium, left-handed and right-handed people approach task and memory performance differently. Left-handers tend to excel when given two tasks to complete simultaneously, thanks to their holistic problem-solving approach, while right-handers tend to break problems into smaller parts for analysis.

More Artistic

Left-handers exhibit greater creativity and imagination as the dominant hemisphere of their brain is associated with artistic expression and creativity. They also tend to favor visual information over language-based data.

Susceptible to Sleep Disorders

Research suggests that left-handed individuals are more likely to experience periodic limb movement disorder (PLMD), a condition in which limbs involuntarily move during sleep. A study revealed that 94% of left-handed patients had bilateral limb movements, compared to 69% of right-handed participants.

Right Brain Dominance

The notion that left-handers predominantly use the right side of their brain is widely recognized. It’s believed that the right side of the brain coordinates the left side of the body and governs artistic and creative tasks. Recent research suggests a more balanced relationship between the brain and body but emphasizes the need for further investigation.

Fear of Left-Handedness (Siniistrophobia)

Some individuals, including left-handers themselves, experience a fear of all things left-handed, a condition known as siniistrophobia.

Tongue Rolling

Interestingly, left-handers exhibit a lower proficiency in rolling their tongues compared to right-handers. Only 62.8% of left-handers can roll their tongues, while 74.8% of right-handers can do so.

A “Sinister” Reputation

Left-handers have often carried a negative reputation throughout history, being associated with weakness, bad luck, corruption, and even evil. The term “sinister” is derived from the Latin word “sinister,” which means “left.”

Delayed Puberty (Claimed but Unsubstantiated)

There’s a claim that left-handed individuals reach puberty 4 to 5 months later than right-handers. However, this assertion lacks substantial scientific support.

Life Expectancy (Disproved)

A flawed 1980s study suggested that left-handed people lived on average nine years less than their right-handed counterparts. This conclusion was largely discredited as it assumed a static number of left-handers over time, which was not the case.

Earnings (Controversial)

Studies on earnings present conflicting results. One study showed that left-handed college graduates earned 15% more than their right-handed counterparts. In contrast, another study suggested that left-handers earned 10% less. The takeaway here is that completing college is the key, regardless of handedness.
