According to recent studies, having two copies of a particular gene are the reason some of us tend to look on the bright side. Those of us who have a long variant of a gene called 5-HTLLPR (or the SERT gene), which helps to recycle serotonin faster and more efficiently than the short variant, tend to be the happiest.
Serotonin is a neurotransmitter that plays an intricate role in our behavior. Lower levels of serotonin in the brain can lead to depression. If you are a 23andMe member, you can view the single nucleotide polyporphism (SNP) data for rs4251417 where ‘C’ would indicate the short variant.
Given how well I know myself and my family history, I was not surprised to learn that I had two copies of the short variant. Some people are very discouraged to learn this about themselves. I look at it this way — knowledge is power. So I’m not hard-wired for happiness… so what? It just means that I have to try a little harder.
I always find that starting the day off with exercise leaves me feeling more positive throughout the day. It may be the LAST thing I want to do when I wake up in the morning, but I know how much better I feel after a workout.
Other ways to boost your serotonin levels include a good hearty meal (yep, that’s why they call it comfort food!) as well as good times with friends or family. Try choosing what suits you best on a given day.
Stay positive! Your genes do play a role in how you feel, but ultimately YOU are in control of your reactions.
