People have made certain adjustements to the way they live and operate to adapt to these conditions.
In the Czech Republic, there is a law that you have to install snow tires every winter. From November 1st to March 31st, Czech drivers must have special tires on their cars that help them more safely navigate the roads. If you are caught without the tires, you can be fined up to 2500 czk (about $125). You must also learn how to drive in the mountains and in foggy conditions, which oftentimes means driving much more slowly.
Beyond safety adjustments, people also have to adjust the kinds of activities they do in the winter in order to stay active and improve their mood. Czech winters are very dark and very long, so it's very important that people find activities that they can do even when the weather is not the best. Cross country skiiing is very popular among Czech people. Many people also participate in indoor fitness activities like yoga, ballroom dancing and more.
