What You'll Learn
Insulation and bedding
Insulation is key to keeping your car warm when sleeping in it during cold weather. The windows, in particular, are a major source of heat loss, so it's a good idea to cover them with foil bubble wrap insulation, thermal or insulated window coverings, or reflective sunshades. Weather stripping can also be added to seal any gaps around the windows and doors, creating a further barrier against the cold.
When it comes to bedding, a good sleeping bag is essential. Choose one with a temperature rating suitable for the conditions you'll be sleeping in, and consider adding a sleeping bag liner to increase the temperature rating. A wool blanket between your sleeping surface and your sleeping bag can add extra warmth, as wool is a natural insulator that doesn't trap moisture. If you're camping in very cold temperatures, you may want to invest in a heated mattress pad or a memory foam mattress topper, which can be preheated before bedtime. A thick memory foam mattress will also provide better heat retention than a sleeping pad.
For additional warmth, you can layer blankets and quilts on top of your sleeping bag. Merino wool long underwear and wool socks can help keep you cozy, as can a hat to retain body heat. A hot water bottle, either plastic or metal, filled with warm or near-boiling water, can also be placed inside your sleeping bag. Just be sure to wrap it in a towel first.

Clothing and comfort
When sleeping in your car, clothing and comfort are paramount. It is important to wear the right clothes and have the right gear to stay warm and comfortable.
Firstly, it is crucial to dress in layers to retain body heat. Thermal or moisture-wicking base layers, warm socks, and a hat will help keep you warm. Wool, a natural insulator, is a great choice for clothing and bedding. It will keep you warm and dry without trapping moisture, which can increase the sensation of cold. Merino wool long underwear and a wool blanket are good options to stay cosy. If you are camping in cold weather, consider a cold-weather sleeping bag designed for lower temperatures. You can also layer it with blankets and quilts for added warmth. A sleeping bag liner can also increase the temperature rating of your sleeping bag.
Additionally, a high-quality, insulated sleeping pad or air mattress will provide essential cushioning and an additional barrier between your body and the cold car surface. A memory foam mattress has better heat retention and can be preheated with a heated mattress pad. A thick memory foam mattress topper can also be a game-changer if you suffer from back pain or discomfort. For your head, a pillow from home or a neck pillow can help prevent neck and shoulder strain.
To keep your feet warm, it is important to insulate them as best as you can. One trick is to fill a hot water bottle with near-boiling water and place it at the bottom of your sleeping bag or by your feet. A Nalgene bottle filled with warm water can also be used, although it won't stay hot for as long. Additionally, keeping your clothes by your feet will help keep them warm.
Finally, consider the comfort of your car's interior. Insulating the interior will minimize heat loss. Use thermal or insulated window coverings, and reflective sunshades on the windshield and other windows. Weather stripping can seal any gaps around windows and doors, creating a barrier against the cold.

Location and safety
When it comes to sleeping in your car, location and safety are paramount. It is generally recommended to avoid busy roadsides and opt for a well-lit and secure location. It is also crucial to adhere to local regulations and ensure that your car is parked legally. One option is to park in a Walmart parking lot, as it is known to be a safe haven for people needing a peaceful night's rest.
Before settling down for the night, it is essential to prepare your car to maintain a comfortable temperature. Insulating the interior of your car is vital to minimize heat loss. Use thermal or insulated window coverings, and reflective sunshades on the windshield and other windows. Adding weather stripping can help seal any gaps around windows and doors, creating a barrier against the cold.
When choosing a parking spot for the night, consider the outside temperature. Experts agree that an outside temperature below -30°F is too cold to sleep in a car, and temperatures lower than 32°F involve some level of danger, especially if you get wet. To stay safe, ensure you have adequate insulated camping gear and a suitable sleeping bag for the expected temperature range.
Additionally, it is important to prioritize your safety by keeping your doors and windows locked. If you need to keep a window slightly open for ventilation or to prevent condensation, ensure it is only open a small amount to maintain security. It is also a good idea to set an alarm to wake up on time and be aware of your surroundings when sleeping in a public place.
Lastly, be mindful of your parking location and any potential hazards. Avoid parking on roads that might get plowed or where you could get blocked in. Consider whether your spot will still be suitable in the morning, especially if there is a risk of snow or icy conditions overnight.

Ventilation and moisture
When sleeping in your car, ventilation and moisture are important factors to consider. Firstly, it is crucial to prevent condensation buildup inside the vehicle. To achieve this, keep the windows slightly open to allow for air circulation. This is especially important if you are using a propane heater, as propane heaters deplete oxygen levels. Even a small crack in the window can help maintain airflow and reduce condensation.
Additionally, moisture from wet clothing or equipment can significantly increase the sensation of cold and make your car sleeping experience uncomfortable. Ensure that you dry your clothes, skis, snowshoes, or boots before bringing them into the car. If they are already inside, unbundle and hang them to allow for faster drying.
Choosing the right materials for your bedding and clothing is also essential. Avoid cotton as it traps moisture and can freeze, potentially making it dangerous in cold conditions. Opt for wool or merino wool instead, as they are natural insulators that keep you warm and dry. Woollen blankets, sleeping bags, and underwear can make a significant difference in your comfort levels.
To further enhance ventilation and reduce moisture buildup, consider using a small, battery-operated fan. This can be especially useful in warmer months when temperature regulation is a priority. Additionally, insulated window coverings and reflective sunshades can help minimize heat buildup and improve airflow.
Remember, while ventilation and moisture control are important, your safety should always come first. Ensure that your windows are only cracked enough to allow airflow without compromising your security. By following these tips, you can create a more comfortable and safer environment when sleeping in your car.
