Can You Sleep with A Lava Lamp On?

Lava lamps tend to drift in and out of fashion, but they’re rarely far from the minds of interior designers. If you’re considering using a lava lamp to enhance your bedroom decor, you need to know the risks.

If you have a lava lamp in your bedroom, turn it off before you go to sleep at night.

Most lava lamps are designed to be used for a maximum of 8 hours at a time. Any longer than this leaves your lava lamp at significant risk of catching fire.

Lava lamps are decorative items, providing stimuli or calm to a living environment. If you think a lava lamp would improve your bedroom decor, they’re a good addition.

Just understand the safety implications of sleeping in a room with a lava lamp.

Are Lava Lamps Safe for a Bedroom?

Lava lamps can make a great addition to any bedroom, due in no small part to the vast array of colors available. You can use lava lamps to create a calming or stimulating environment, enhancing existing bedroom color schemes based on paint or wallpaper.

The striking visuals produced by lava lamps are created by heat. The ‘lava’ element of the light is made from wax, usually created by blending perchloroethylene and paraffin. The liquid this wax floats within is typically water, antifreeze, and salt.

To make a lava lamp, a glass container holds these liquid and wax states, and a direct heat source is applied. A 40-watt bulb will typically do the trick here.

Overall, lava lamps are a marvel of engineering and science, but they’re also dangerous. Combining all these materials means that you’ll have a potentially flammable object on your hands.

You’ll need to tread carefully and turn off a lava lamp overnight.

How Long Can I Leave My Lava Lamp on?

If you have purchased a lava lamp from a store, carefully review the safety information found on the label. Typically, this will recommend that the light is not switched on for more than 8-10 hours.

Abide by these guidelines, as a lava lamp that is left to burn too long can become dangerous. Lava lamps are designed to help you enjoy the light show they create, not sleep through it.

What Happens if You Leave a Lava Lamp on Too Long?

The color that makes a lava lamp so visually appealing stems from wax. This wax is heated by the 40-watt bulb found at the bottom of the light. This heat reduces the density of the resin, encouraging it to rise.

What comes up must come down. As the wax reaches the top of a lava lamp, it cools off and starts to sink back to the bottom, where the whole process begins again.

Sooner or later, this becomes risky. Running a lamp for this long without a break is never advisable, especially when you’re encouraging the bulb to attract wax. Eventually, it becomes a fire hazard.

The light displays are made to be admired, not dozed through. Leaving a lava lamp on while you slumber disturbs your sleep at best and places you at significant risk at worst.

Fire Hazard

The most significant risk of a lava lamp is fire. Aside from periodically switching off the lava lamp and leaving it to cool off fully, basic safety steps to keep a lava lamp in a bedroom fireproof include:

  • Avoiding clutter around the light, especially flammable materials such as paper or books
  • Keep an eye on the aesthetics of the lamp. If the wax is not flowing, switch it off at once
  • Don’t touch or allow a pet or child to touch a lava lamp that has recently been in use
  • Never place the lava lamp on or near another direct heat source, including a windowsill that allows direct sunlight
  • Never use a lamp with a greater wattage than 40

Lava lamps are best located in a larger bedroom, locating the light somewhere far from anything else that would impact it, on as long as a lead as possible.

Can Lava Lamps Catch on Fire?

Homemade or low-cost lava lamps are the likeliest to catch fire.

Any lamp that is left plugged in constantly without having the opportunity to cool off is a risk, though. Equally, replacing a 40-watt bulb with a more robust alternative increases the hazard.

If you’re going to have a lava lamp in your bedroom, consider having a fire extinguisher on hand. This is not said to be alarmist but advised as a precaution. Unplug your light enough, and it won’t be a concern, but a lava lamp is a theoretical fire hazard in any room.

Can Lava Lamps Topple Over?

Lava lamps are only as sturdy as the materials used to create them and the location they are found in. This means that a lava lamp could easily topple over. When it does so, this risk of fire becomes increasingly pronounced.

A lava lamp could be knocked over by the following:

  • A sharp gust of wind blown in through an open window
  • Clumsy and explorative pets, most notably cats, that wander around the home at night
  • Kicking and thrashing in your sleep
  • Knocks to the lamp when making a bed or getting dressed

The hazards of a lava lamp being knocked over aren’t restricted to fire.

The contents of a lava lamp may be toxic to humans or animals. Clinical Practice and Cases in Emergency Medicine explains how ingesting the contents of a lava lamp can lead to blood disorders.

Visual Stimulation

Arguably the overriding component of a lava lamp is the visual impact.

Different lava lamps have varying implications for viewers. Some people find lava lamps exciting to watch, while others find the light show relaxing.

If you fall into the latter camp, there’s plenty to like about relaxing to the light show of a lava lamp. Like TV screens and other stimulation forms, lava lamps need to be used sparingly at night.

There’s no denying that a lava lamp excites the senses. Some parents of autistic children use them to create an environment of controlled visual stimuli. You’ll need time to cool off after watching the lights before attempting to sleep.

If in doubt, switch off a lava lamp no less than an hour before getting into bed. This should be enough time for your eyes to enter a state of calm. That will, in turn, lead to a relaxing night of slumber.

Increased Ambient Temperature and Noise

As discussed, many people use a lava lamp to relax and unwind. Such an appliance, especially a cheap or low-rent version, will likely have the opposite effect if you try to sleep with it switched on.

Consider the noise that a cheap lava lamp will emit. Like all poor-quality technology, a constant low hum is likely to be emitted. That may not seem like a big deal, but it can quickly grow infuriating, especially when paired with the light show of a lava lamp.

Humming technology is one of those things that, once heard, can longer be ignored. Before too long, you’ll likely need another noise to distract you. If you prefer to sleep in silence, that will become problematic before too long.

Another consideration is the heat that will be released from a lava lamp. As we explained earlier, a lava lamp is hot at the base and cool at the top. This heat will spread and radiate, potentially increasing the ambient temperature in the room and keeping you awake.

Burning Out the Lamp

Remember that all lava lamps have a shelf life. On average, you’ll get around 10,000 hours of use from a superior, store-bought lava lamp. If you keep it on overnight, that time will drastically reduce and shrink.

If you make your own lava lamp at home, this becomes increasingly likely. You’ll quickly find that the lamp burns out and fails to meet your long-term plans. As discussed, don’t replace the bulb with another, more powerful alternative as that will magnify any risks. 

Lava lamps are best enjoyed during the early evening before retiring for the night. Use the light show provided by the lamp to calm down before the end of the evening.

In the spirit of safety, switch off the lamp and let it cool for some hours before submitting to sleep.
