VAN-COMPARATOR Guide
How to sleep well in a campervan: bedding, darkness and temperature, the guide
Mattress, window blackout, temperature and noise: what actually determines sleep quality in a campervan or motorhome, what the research shows, and the mistakes to avoid.
You painstakingly plan the route, the budget, sometimes even the hiking list — and almost always overlook the question that actually shapes the rest of the trip: will you actually sleep well? A bad night in a van ruins the following day far more reliably than a rain shower. Here’s what really matters, backed by what sleep research actually shows.
The mattress: the starting point
The stock bedding in rental campervans, especially older models, is often just 8-10 cm of thin foam — fine for one night, not for a week. A 5 cm memory-foam topper, easily stowed under a seat, transforms comfort without taking up much space. Before booking, check the listing’s photos and description for mattress thickness and type rather than finding out on arrival.
Darkness: what the research shows
A 2022 study in the Proceedings of the National Academy of Sciences by Ivy Mason, Phyllis Zee and colleagues at Northwestern University (DOI 10.1073/pnas.2113290119) found that a single night exposed to moderate room lighting (100 lux, roughly an overhead light left on) was enough to raise nighttime heart rate and next-morning insulin resistance compared with a night in near-total darkness. In practical terms: invest in effective blackout covers for the windscreen and side windows, especially in summer at northern latitudes where daylight barely fades.
Cabin temperature
A landmark study by Kazue Okamoto-Mizuno and Koh Mizuno, published in 2012 in the Journal of Physiological Anthropology (DOI 10.1186/1880-6805-31-14), shows that both excessive heat and excessive cold increase wakefulness and reduce deep and REM sleep. The optimal range generally sits around 16-19°C. In summer, a roof fan or simply cracking the windows for cross-ventilation (see our guide to RV ventilation) is often enough; in winter, a well-regulated auxiliary heater beats an overheated cabin that turns freezing by dawn.
Noise, the quiet culprit
Rain on the roof, wind in the branches, a neighbour’s door slamming at 6am: noise remains one of the leading causes of broken nights in a van. Foam earplugs, packed in the wash bag before you even leave, solve most of the problem for next to nothing. Choosing where to park matters just as much — our guide to overnight parking etiquette explains how to spot a genuinely quiet spot rather than just a legally permitted one.
Mosquitoes, the quiet saboteur
A single mosquito in the cabin is enough to ruin an entire night, closed van or not. Magnetic or zip-on mosquito screens for the rear doors and sliding windows, sold as universal accessories, are well worth their price across Southern Europe as much as in the midge-infested Scottish Highlands — our guide to mosquitoes and bugs in a campervan covers the right gear by region.
What to pack for a genuinely good night
A minimal kit covers most situations: blackout covers for every window, earplugs, a sleep mask as backup, and your own fitted sheet rather than the sometimes basic bedding some rental companies provide. These few accessories, which fit in a small bag, shape trip quality far more than the final choice between two comparable van models.
