resync your

inner clock

Our 24-hour body clock is determined by the natural light-dark cycle and affects our wellbeing like sleep and hunger. When we travel overseas our internal rhythm is misaligned and causes jet lag.

Well timed exposure to blue light a few days before and after your trip helps you adapt faster to a new time zone. Pocket Sky allows you to work at your full potential or enjoy your holiday from day one.

Flying east: Start a couple of days before your journey. Get up earlier and indulge yourself with Pocket Sky. After your arrival use Pocket Sky in mid morning for another few days, readjusting your inner clock by two hours each day.

Flying west: Use Pocket Sky in the late afternoon for a couple of days before departure. Upon arrival use Pocket Sky early in the afternoon.

Circadian Rhythm

All life on earth, human or animal, operates on 24-hour rhythms. This body clock, the Circadian rhythm, is vitally governed by sunlight. Its blue component triggers the suppression of melatonin, a sleep-inducing hormone, and thus keeps us awake and well. It controls critical functions such as our behaviour, hormone levels, cell regeneration, body temperature, or metabolism. Light also determines our sleep and wakefulness, depending on the time of day. If our inner clock is disturbed, our wellbeing suffers and serious disorders can be the consequence.

The existence of an inner clock and its importance for life has been demonstrated by three American researchers, awarded with the Nobel prize for Medicine in 2017. It has also been proven that our inner timekeeper is set by the light the body receives. If our lifestyle is misaligned with our body clock, because we work in shifts, travel overseas or do net get enough sunlight, our mental and physical wellbeing is impaired.
