5 Ways Being Left-Handed Affects Your Health

Being left-handed is a unique characteristic that sets most people apart, especially since a majority of people are right-handed but linking this attribute to health is now an emerging concern for many. Here’s how being left-handed affects your health;

Brain structure and function

Left-handed people may exhibit differences in brain structure and function compared to their right-handed counterparts.

These differences are prominent in the corpus callosum, the bundle of nerve fibres connecting the brain’s hemispheres, which could influence cognitive abilities and processing speed.

How they think

Some studies have also suggested that lefties tend to think differently from people who are right-handed.

A study conducted in 2009 showed right-handed people preferring items on the right while left-handed people would typically go with anything placed on the left-hand side.

Mental health

There’s also a suggested link between being left-handed and mental health issues.

While the evidence is not conclusive, researchers have explored associations with conditions such as schizophrenia and bipolar disorder.

There have also been links between non-right-handedness and dyslexia, attention deficit hyperactivity disorder, and some mood disorders.

Links with cancer

Being left-handed also means a slightly higher risk of cancer. A 2007 study showed that left-handed women had a higher rate of breast cancer compared to right-handers.

This was observed in women in both post-menopausal and premenopausal ages. However, the study did not show how this can happen exactly.

Physical health challenges

Living in a predominantly right-handed world can pose physical challenges for left-handed individuals. Tools, gadgets, and even classroom setups are often designed with right-handed users in mind.

Adapting to these environments may contribute to increased stress and discomfort, potentially impacting overall well-being. However, left-handedness can provide a unique advantage in sports.
