Jet lag: How much does artificial light help?

Blaulicht gegen Müdigkeit Lichtdusche

After air traffic has been very limited in recent years, things will look completely different again in 2022. According to a study , passenger occupancy in international air traffic is over 80 percent - this figure is lower in the Middle East, Asia and Africa alone. With the increased volume, more people are suffering from the strain, especially from long-haul flights. The diagnosis is often: jet lag. But what exactly is jet lag? What causes it and how can it best be counteracted?


What is jet lag?

First of all: jet lag is not an illness. Jet lag is more likely to be a health disorder caused by quickly crossing time zones. This throws the internal clock out of sync and shifts the usual rhythm of day and night because it is synchronized by light. This means that you move it too quickly through long flights and you can't keep up. The most common symptoms include:


  • Fatigue, physical and/or mental
  • Mood swings
  • Difficulty concentrating
  • Lack of sleep or problems falling asleep
  • Digestive problems
  • Irregular heart rate


The body has its own biorhythm, which all mental and physical functions are based on; this always lasts around 24 hours. Whether pulse rate or body temperature, the body regulates its activities independently at any time of the day or night. A functioning metabolism in particular makes it easier to switch between rest and activity phases.

What's interesting here is that the adaptation problems for the body can also be related to the direction in which you are flying. A flight lasting several hours in an easterly direction shortens the physical experience of the day. Even at late local time, the activity and vitality hardly correspond to the local nighttime conditions. Conversely, a flight westwards means that the day is longer and fatigue sets in at an early hour.


Home remedy light: This is how jet lag is tricked

The best tip is of course to get used to the “new” time zone before departure, which means going to bed earlier or later. This works best if this habituation phase is started a few days beforehand. Sunlight here plays a large part in how we feel. It ensures that the metabolism gets going and stimulates many other activating processes in the body. The light ensures relaxation and influences mood, attention and performance. Ultimately, it is largely responsible for the fact that we have a functioning day-night rhythm. And that is exactly what jet lag poses as a major challenge for the entire organism.


Our HEAVN ONE Series II can help here: with the light shower function and the biological effect of 10,000 lux you can ideally prepare for long-haul flights. Activating light gets your body used to the unusual day-night rhythm before you take off. The innovative technology ensures lighting conditions that correspond to 95 percent of sunlight. Waking up early can move the day forward with a shower of light in the morning and cool light in the evening can move the day back. This way you will be productive even in winter and benefit from improved vitality.

You will see that light is more than a home remedy for jet lag - it accompanies you throughout the day and is largely responsible for your performance.
