Jet Lag

Each year millions of travelers undertake long distance flights over one or more continents. Jet lag occurs when you travel across multiple time zones and have trouble adjusting to the new time schedule. After traveling a long distance by air, your biological clocks may still be aligned with the time zone from where you came from. The result of this misalignment is that you’ll feel sleepy when it is daytime in the new time zone or be awake when you are supposed to sleep.


Jet Lag symptoms: reduced alertness, nighttime insomnia, loss of appetite, depressed mood, poor psychomotor coordination and reduced cognitive skills.


The program "Outsmart your Jetlag" focusses on improving circadian alignment and include correctly timed Melatonin administration, adaptation of light exposure, sleep hygiene measures and targeting specific symptoms.

Largely because of its regulatory effects on our circadian system, melatonin has proven to be highly effective for treating the range of symptoms that accompany transmeridian air travel.

Shift work

Shift work comprises work schedules that extend beyond the typical "nine-to-five" workday. Schedules often comprise early work start, compressed work weeks with 12-hour shifts, night work, early start followed by a late one and vice versa.


Shift work disorder is prevalent in our 24/7 society and has been associated with significant health and safety repercussions


Individual tolerance to shift work is variable and is influenced by the number of consecutive work hours and shifts, the rest periods, the predictability of work schedules, but also by the genetic constitution of the shift worker (the chronotype). 


Safety percussions are often linked to sleepinessleading to impaired vigilance and performance. Health problems include mood disorders, weight gain, metabolic disturbances, type 2 diabetes, cardiovascular diseases, hypertension, and even cancer. 


The audits on shift work  are tailored to the assessment of health and sleeping problems, type of shift, work-personal balance, working place conditions and the individual chronotype.
