We often talk about genes in simple terms, like who we get our eye color from. However, the list of things that we can inherit from our parents is much longer. Our genetic makeup affects more than just our hair, skin, or eye color. According to scientists, almost every behavior or preference we have could actually be a genetic trait.
We were shocked by these facts, so we invite you to take a look at these 5 traits you may have, but didn’t know were passed down to you genetically.
Only 4 Hours Of Sleep May Be Enough For You
Doctors generally recommend around 8 hours of sleep each night to keep our brains and bodies working. However, some people report sleeping up to 2x shorter without experiencing any side effects.
These so-called elite sleepers can live on 4-6 hours of sleep thanks to the gene found in up to 5% of people. These genes allow people to remove toxins from the brain and body during sleep more efficiently than others, requiring less time to rest and cool down.
You May Be Genetically Predetermined To Tolerate Pain And Spicy Food
If you have a high tolerance for pain and spicy food or no tolerance at all, your genetics are likely to blame. Furthermore, MC1R, the same genetic variant that gives people red hair, also indicates their sensitivity to pain. This is why gingers may have a higher pain tolerance in general.
Coriander May Smell Like A Soap To You
While some people can’t imagine a meal without a pinch of chopped fresh cilantro, others can’t stand the taste of this herb. This hatred is caused by markers located near genes that determine our sense of smell with receptors that detect aldehydes, compounds found in soap.
Aldehydes are also a component of cilantro’s aroma, which is why some people report a soapy aftertaste when they eat it. So the next time someone refuses to eat cilantro, blame genetics instead of assuming the person is spoiled.
The “blue Genes” May Affect Your Need For Socialization
The researchers conducted a study in which genes are linked to sadness. It turned out that these genes can also influence our need for socialization and feelings of loneliness.
Therefore, genetic inheritance may explain why some people are social butterflies, while others find comfort and happiness in an isolated lifestyle.
Sneezing At The Sun Is A Genetic Trait
Sneezing is often associated with the flu or allergies, but some people have a specific syndrome called “photic sneezing.” Those who experience it can’t help but sneeze every time they are suddenly exposed to bright light.
Photic or light sneezing is a dominant trait, which means that if one of your parents has this reflex, you have a 50% chance of having it too.
Do you think you have any of these genetic variations?
