Insufficient sleep and chronic fatigue lead to tens of thousands of serious road accidents every year in Europe. 20% of serious accidents are the result of falling asleep behind the wheel or serious fatigue.

International studies indicate that with sleep under 5–6 hours a night, the risk of a crash increases 3–5 times. If the driver is not well rested, his reaction, concentration and motor skills decrease drastically — an effect comparable to alcohol intoxication.

The World Health Organization and the European Commission report that lack of sleep is the cause of over 3,000 deaths on the road annually in the EU — about 15% of all victims. In Bulgaria, serious accidents in 2025 remain at a high level, and fatigue and impaired attention are among the leading indirect causes.

Practical recommendations from doctors and specialists:

The official guidelines of the European Parliament for 2025 provide for the introduction of intelligent systems in cars, which monitor attention and automatically warn the driver if a deviation or signs of drowsiness are detected.

The constant fight against fatigue and good sleep hygiene not only save lives, but also reduce injuries, treatment costs and the burden on the emergency services.
