Tackle Jet Lag with a New and Smart Wearable Technology

Tackle Jet Lag with a New and Smart Wearable Technology

Scientists have developed a way to counter jet lag by delivering personalised advice using an advance that may help, wearable technology.

The researchers, including those from Rensselaer Polytechnic Institute in the US, said alterations in the body’s internal clock – called the circadian rhythm – cause individuals to experience jet lags. The researchers added that this internal clock helps regulate lots of our physiological processes and even how our brain functions.

In the study, published on Wednesday, 18 December in the journal PLOS ONE, the investigators demonstrated a collection of algorithms that can analyse biometric information recorded by a wise device, and then suggest the best combination of light and sleep to enable someone readjust their circadian rhythm.

“Using these algorithms and a mathematical model of a person’s circadian rhythm, we have the ability to compute the best light to adjust your circadian rhythm and boost your well-being.

Julius said the tool recommends the kind of sleep — both when it should be obtained and how much — that a individual needs. According to the researchers, other biological processes, and people’s energy, alertness can suffer when their circadian rhythm does not align with the time zone they’re trying to follow.

Study co-author, agung Julius, Rensselaer Polytechnic Institute. “The sleep and circadian procedures are also very tightly related to your mental state and how alert you are. If you attempt to do something in the wrong time of day, your alertness is not going to be as successful as though you do it in the ideal time of day as defined by your circadian clock.”
A person’s circadian rhythm variation is determined using data gathered from a saliva or blood test that measures levels of the hormone melatonin.

This approach had a problem, according to the researchers, as obtaining doesn’t allow for analysis, and these test results takes time. In the current study, the investigators used algorithms they developed to process information — like body temperature and heart rate — collected from technology that was smart.

They said these algorithms converted the data into an estimate of a person’s circadian rhythm variation from wearable technologies. The estimates were with the hormone measurement techniques used by labs, the scientists stated. “The question is whether that sort of data can provide you as accurate an estimation as the clinical standard,” Julius said.

With the new technology, the researchers said, it is now possible to effectively use light to optimise and maintain human health and performance.
