Light therapy treats jet lag problems, also known as jet lag, which is the result of quickly crossing (usually by plane) several time zones. It is translated into disturbances of the biological clock of which the duration and intensity are proportional to the number of time zones. The harmful effects of jet lag are only felt after 3 time zones. (example: a flight from Paris - Moscow).
What causes jet lag
The cause is crossing several time zones too quickly, not allowing the internal clock (biological clock) to adapt to the external time.
How do I know if I’m suffering from jet lag?
The most frequent symptoms are:
- Insomnia
- Drowsiness
- Physical tiredness
- Intellectual tiredness
- Mood problems
- Difficulties concentrating
How can jet lag be fought against?
Jet lag is not a pathology in the strict sense of the term. Therefore, we do not talk about a treatment but rather a solution for a better well-being. These make up part of the classic tool for chronotherapy, namely the tools which enable the resynchronization of the biological clock to its new time. We count 3 main “tools” which the traveller can use to reduce the effects of jet lag: light therapy, taking melatonin, avoiding light and sleep.
