Fatigue is Partly Influenced by Genes

Genes may contribute to why some people suffer from low energy levels or tire easily. According to recent research, being prone to fatigue is partly heritable, with genetic accounting for 8% of differences between individuals who were asked about their tiredness levels.
The study was led by Saskia Hagenaars and Dr. Vincent Deary, from the University of Edinburgh and Northumbria University respectively. They examine genetic make-up of 111,749 people who had reported whether they had low energy or felt tired in the two weeks before collection of data.
Also, the researcher also discovered that genetic predisposition to fatigue was also present in individuals genetically susceptible to various physical and mental health conditions, such as schizophrenia, depression, and smoking. Additionally, an overlap was identified between low levels of energy, and high levels of cholesterol and obesity.
According to the scientists, this raises the likelihood of a genetic linkage between fatigue and a susceptibility to physiological stress. The researchers also found that there was an overlap between a general tendency to poor health and tiredness.
The researchers said that most of the differences in tiredness are mainly environmental. The genetic data accounted for just 8.4% of people’s differences in tiredness. The findings were published in the journal Molecular Psychiatry.
