Do you feel wide awake as soon as you get up or feel more energised during the evening? This is all to do with your personal body clock.
Known as the body’s circadian rhythm, it’s the function that makes sure we go to sleep at night and able to wake up for work and last during the day. However, everyone’s varies.
Now scientists have developed a system that allows people to find out exactly what their personal body clock is and when their hormones (which affect it) peak. It’s all via a computer algorithm software called TimeSignature which uses blood samples and artificial intelligence to determine the results.
Being able to determine your circadian rhythm, is not only useful for finding out when you’re most awake, and therefore productive during the day, but it’s also a great way of being able to have a better chance of reducing the likelihood of you developing sleeping problems such as insomina.
The test requires you to take two blood tests 10 to 12 hours apart. The software then analyses 7,000 genes in the blood sample to find out at what times these genes peak throughout the day and identify the 40 genes that make up a person’s circadian rhythm.
“Before we didn’t have a clinically feasible way of assessing the clock in healthy people and people with disease,” explains the study’s co-author Ravi Allada, professor of neurobiology at Northwestern University, to the Independent.
“Now we can see if a disrupted clock correlates with various diseases and, more importantly, if it can predict who is going to get sick.”
Indeed, the researchers say that knowing people’s circadian rhythm could also mean that doctors could determine if certain patients are more susceptible to medication during particular times of the day.
“Knowing what time it is in your body is crucial to getting the most effective benefits,” said co-author Dr. Phyllis Zee, chief of sleep medicine in neurology at Northwestern University.
“The best time for you to take the blood pressure drug or the chemotherapy or radiation may be different from somebody else.”
What do you make of the new testing? Will you be finding out your circadian rhythm?
