Remember to do leg, arm and neck exercises in your seat. All airlines suggest a set of exercises and it is advisable to do them. Long flights can cause blood clots (deep vein thrombosis), so move your limbs around to get your circulation going.
Business trips are stressful. Exercise before you leave and on arrival too. Even a brisk walk around the hotel where you are staying will get your brain cells functioning efficiently. Airports are large, so walk around briskly for 10 minutes just before your flight.
Don't drink too much alcohol on the flight. It will make you feel sluggish on arrival and increases jetlag. Water is a good substitute.
If you are staying in a hotel with a gym, try to fit a half-hour workout into your schedule. It is beneficial.
