    What is this app?

    When a traveler crosses more than 3 time zones quickly, his internal clock is out of sync with his place of arrival, it is the principle of jet lag and this can lead to more or less important disturbances: sleep disorders, digestive disorders, concentration...

    Light is the main synchronizer of this internal clock that follows a circadian cycle (alternating sleep/sleep in 24 hours), but there are other secondary such as diet, physical exercise...

    Thus, by performing actions such as exposure to light, special meals, nap... at specific times of the day, the body will resynchronize itself in a gentle and natural way.

    Sleep Center expert

    From a medical perspective, we are familiar with the broad concepts of advice to travellers to avoid the signs of jet lag. But to date, there is no program specifying the hours of countermeasures to be applied according to the sleep of each and the journey made.

    The idea was born from a collaboration with Gowwiz and the sleep center to create an algorithm offering, via a mobile application, the measures to avoid this desynchronization.

    A new feature:

    Coaching you in taking your medical treatment when you travel.

    Because, in practice, it is not always easy to follow a cardiac treatment, for the thyroid, or quite simply the contraceptive pill when you take long-haul flights! When you cross several time zones, managing the taking of tablets quickly turns into a nightmare.

    The solution ? Gowwiz offers a brand new function: taking medication. Thus, despite the jet lag, each traveler will gradually find themselves at their destination with the right time to take treatment.
