The Hidden Risks of Sleeping in Your Car During Disasters — It’s Not Just About Blood Clots.
In recent years, sleeping in your car during natural disasters—such as earthquakes, typhoons, or floods—has become a common way to seek safety when homes are damaged or unsafe. While it can be a practical short-term solution, many people are unaware of the serious health and safety risks associated with long-term car sheltering.
The term “Economy Class Syndrome” refers to deep vein thrombosis (DVT), a dangerous condition caused by poor blood circulation during long periods of sitting. While this is often highlighted in news coverage, it’s only one of the many health concerns. In cramped cars, people may remain still for hours or even days, increasing the risk of blood clots and cardiovascular strain.
Keeping windows closed for safety or warmth can lead to poor air circulation. In colder seasons, using the engine or portable heaters can result in a dangerous buildup of carbon monoxide, a deadly odorless gas. It’s crucial to ensure adequate ventilation and avoid running the engine while sleeping.
Without access to clean toilets, running water, or garbage disposal, maintaining hygiene in the car becomes difficult. This can increase the risk of infections, foodborne illnesses, and stress-related health issues.
Staying confined in a small space without privacy or comfort for extended periods can cause anxiety, sleep deprivation, and emotional fatigue. These factors can weaken your immune system and impact decision-making in already stressful situations.
Car shelters may seem safer than unstable buildings, but they also present risks of theft, assault, or accidents—especially in poorly lit or crowded parking areas. It’s important to stay informed about local evacuation centers and support services.
Tips for Safer Car Shelter During Emergencies
While sleeping in your car may seem like a quick solution in times of disaster, it’s vital to understand the hidden dangers. Preparation, awareness, and flexibility can make all the difference in staying safe and healthy during emergencies.
