Carbon monoxide poisoning
Carbon monoxide (CO) is a colourless, odourless, and deadly gas produced by the combustion of fossil fuels such as gasoline, diesel, or wood. When a car is left running in an enclosed space, CO can quickly accumulate to lethal levels.
The gas is harmful to human health when it accumulates in enclosed areas. For example, a parked car left running with all its windows closed. The gas kills when a large amount binds to red blood cells and displaces oxygen, eventually suffocating the body by depriving it of an adequate oxygen supply.
People sleeping in a car may die from carbon monoxide poisoning without ever experiencing symptoms. However, those who are awake may experience symptoms such as headaches, nausea, dizziness, vomiting, chest pain, difficulty breathing, confusion, and seizures. The longer a person inhales the gas, the worse the symptoms will be. Losing consciousness can occur within two hours if there are high levels of carbon monoxide in the air.
To prevent carbon monoxide poisoning, never leave your vehicle's engine running when parked in an enclosed or partially enclosed space. Even with the windows open or the garage door open, carbon monoxide can reach dangerous levels in the vehicle. Regularly check and inspect your car exhaust system for leaks, as this can also allow carbon monoxide to enter your car. Install a carbon monoxide detector in your car as a safety precaution.

- Dress in layers to keep warm, including a base layer of merino wool to regulate body heat and wick sweat.
- Wear multiple pairs of pants and socks to protect your legs and feet from the cold.
- Use a 0-degree sleeping bag and add extra blankets if needed.
- Invest in heated seat covers to keep you warm while sitting and sleeping.
- Use a portable heater or the car's HVAC system to generate heat before you sleep, but be sure to turn it off before you fall asleep to avoid carbon monoxide poisoning.
- Park your car in a safe, well-lit area to help deter crime and enhance your security.
- Keep a charged phone and emergency supplies, such as a first-aid kit and a flashlight, within reach.
Hot Weather
Sleeping in a car during hot weather can also pose some challenges. Here are some tips to stay cool and comfortable:
- Crack the windows open slightly to allow for air circulation and prevent the car from becoming too stuffy and hot.
- Use window visors or rainguards to keep the rain out while allowing airflow.
- Install roof vents or fans to provide ventilation even with the windows closed.
- Park in a well-lit and safe area to allow for better airflow and security.
- Use sunshades or window covers to shield the car from direct sunlight and keep the interior cooler.
- Stay hydrated by drinking plenty of water or other fluids.
- Consider sleeping outside the car if the weather is pleasant and accommodating. Set up a campsite or use a tent for added comfort and protection from the elements.

Safety and security
Sleeping in a car with the windows closed is not recommended due to the risk of carbon monoxide poisoning. Carbon monoxide is a colourless, odourless, and deadly gas that can seep into the car from the exhaust pipe or other sources. When the windows are closed, carbon monoxide can build up inside the car, leading to dizziness, nausea, and even death. Therefore, it is crucial to keep at least one window slightly open to allow ventilation and prevent carbon monoxide buildup.
Additionally, sleeping in a sealed car can lead to air circulation issues, resulting in stuffy and uncomfortable air. The lack of fresh oxygen can make it harder to breathe, especially for those with respiratory issues. Keeping a window open, even slightly, can help improve air circulation and ensure a steady supply of fresh air.
Another safety concern is the temperature inside the car. In hot weather, the temperature inside a closed car can rise rapidly, leading to overheating and potentially heatstroke. Conversely, in cold weather, there is a risk of hypothermia. Therefore, it is important to consider the outside temperature and adjust the number of open windows accordingly.
When sleeping in a car, it is also essential to prioritise personal safety. Choose a safe and well-lit location, such as a rest area or truck stop, and ensure that your doors are locked. Be mindful of local regulations and respect any signs prohibiting overnight parking. Additionally, maintain privacy by using window shades or curtains while still allowing for some visibility to stay aware of your surroundings.
To enhance your safety, keep a charged mobile phone and emergency supplies, such as a first-aid kit and a flashlight, within reach. It is also crucial to have an exit plan in case of an emergency.
While it is important to prioritise safety and security when sleeping in a car, it is equally important to be a responsible car sleeper. Respect the local community and avoid parking in areas where overnight parking is prohibited or disruptive. By being mindful of others, you can maintain a positive image for car sleepers and minimise potential conflicts.
