Prevent jet lag
A frequent flyer’s worst enemy is jet lag. It takes so much time to get used to different time zones. If you don’t want to lose a whole day in France sleeping in your hotel, try jogging for a while. You will stay alert and won’t wake up in the middle of the night with nothing to do yet.
The sun and exercise help your body accustom to the new time zone. Always bring running shoes and workout clothes on your trip; they don’t take up that much space in your luggage. It will also help you stay alert and comfortable walking through the city.
