With some tricks you can better adapt to your new environment. If possible, the waking and sleeping times should be postponed two to three days before the flight. Those traveling west should go to bed later and go to bed earlier on a flight east. Anyone who adjusts to the new local time during the flight and participates in the regular social life after arrival, makes the time change easier.
It also includes outdoor exercise and exercise for better "biological synchronization". This means that the biological rhythms adapt faster when exposed to bright sunlight.

On the tablet intake, a time shift lasting several hours can have a very negative effect. The best known example is the contraceptive pill. According to a recommendation of the Federal Association of German Pharmacist Associations, the pill should be taken at home at the usual time. If this is not possible, the intake interval between two tablets should be shortened rather than prolonged. The additional pill required for this can be taken from the reserve pack and swallowed twelve hours after the last regular dose.
For combination preparations with estrogens and progestins, this change can usually be tolerated more easily than with the so-called mini-pill, which contains only progestin. If the mini-pill is missed by more than three hours, it will no longer be reliable. However, since diarrheal diseases, which can occur frequently, especially when traveling to tropical countries and warm holiday destinations, significantly affect the effect of the pill, it is worth recourse to additional methods of contraception. In addition, condoms protect against HIV and other sexually transmitted diseases.
