Prolonged sitting in a commercial truck cabin increases the risk of Deep Vein Thrombosis (DVT / tiefe Venenthrombose) and chronic cardiovascular disease. What evidence-based preventive measures should a professional driver incorporate during daily driving breaks?

1. Perform calf muscle pump exercises (toe-raising and ankle circles), walk actively for 10–15 minutes during breaks, maintain generous water intake, avoid crossing legs when seated, and wear medical compression socks if prone to venous insufficiency
2. Remain completely stationary in the driver's seat and avoid moving during all 45-minute breaks
3. Consume energy drinks and smoke cigarettes to increase blood circulation
4. Tighten belts and restrictive clothing to stop blood pooling in the feet
