Jet lag: what is this phenomenon and how to overcome the effects of flights?

Jet lag is such a strange feeling that occurs when we quickly fly across several time zones, for example, when traveling by plane from Kyiv to New York. The body is used to living in one rhythm, and we abruptly shift it to another. As a result, you feel a bit off: it's hard to fall asleep or wake up, fatigue sets in, and even a bit of irritability appears. In simple terms, jet lag is when your “internal clock” is slightly out of sync with the real time. The human body has an internal clock (circadian rhythms) that regulates sleep, body temperature, and hormones. When you abruptly change time zones — it doesn't have time to adapt, and discomfort arises. To cope with jet lag more easily, try to gradually prepare for the new time zone before your trip. For example, a few days before departure, go to bed and wake up a little earlier or later, depending on the direction of travel. After arrival, being outdoors helps — sunlight aids in adapting to the new rhythm. And don't forget to drink enough water, as in the airplane, due to the dry air, it's easy to become dehydrated.
