How Long Can You Leave a Salt Lamp on

Salt lamps have been used for centuries in countries like India and Pakistan because they emit both heat and light, which can benefit those with respiratory problems, allergies, asthma, etc. In this blog post, we will cover how long can you leave a salt lamp on and also some benefits of it.

What is a Himalayan Salt Lamp? 

A salt lamp is a decorative rock-like object that gives off an orange glow when lit. The orange color is said to have health benefits. For example, it’s said that the salt lamp relieves stress, allergies, and asthma symptoms, prevent infections, improves mood, and boosts energy levels.

A salt lamp’s soft, calming light is perfect for creating a tranquil atmosphere in bedrooms and offices. These lamps are also commonly used in spas and yoga studios and are believed to be beneficial for people with Seasonal Affective Disorder, as the light can help to improve mood.

8 Benefits of Himalayan Salt Lamp:

Health and Beauty

The Himalayan salt lamp is said to have many health benefits. It can help detoxify your air, reducing the effects of airborne pollutants and allergens in the room within which it is placed. The lamp also emits negative ions, which can neutralize positive ions producing a calming effect and reducing stress.


As you gaze at the mesmerizing flame and the glowing salt crystal, it is easy to get lost in the rhythm of your breathing. However, this is a great way to relax and unwind after a stressful day.

Aesthetic Appeal

A Himalayan lamp’s soft glow can add warmth and a peaceful mood to any room or office while creating an overall relaxing atmosphere. Its unique luminosity can enhance any decor, whether contemporary or traditional.

Cleanses the Air

The lamp is made of salt and attracts moisture from the air. It emits negative ions at a rate that depends on the distance between each bulb. The lamp can also prevent your skin or furniture from becoming too dry in the wintertime.

Alleviates Symptoms of Allergies

The salt crystal in the lamp cleanses the air and rids it of pet dander, pollen, dust, mold spores, and other airborne allergens. Place one in your bedroom and enjoy clean, healthy air without chemical perfumes or additives.

Improves Sleep Quality

When you’re in the dark, your eyes are naturally drawn to the glowing salt lamp. Since a human being’s circadian rhythm (internal clock) is linked to light and darkness, it will help you drift off faster.

Promotes Calm

A Himalayan salt lamp is perfect if you want a soothing influence in your room after a long and tiring day. It can help calm you, reduce stress and regulate your breathing while setting the perfect mood for rest and sleep.

12 Factors That Determine How Long Can You Leave a Salt Lamp on:

1. Type of Salt Lamp:

Himalayan salt has small crystals compared to rock salt.

2. Size of the Lamp:

The bigger the lamp, the more time you can leave it on before it heats your room.

3. Diameter of Tube Bulb:

Halogen bulbs give out red light, safer than white light for your eyes and sleep cycle. But halogen bulbs draw more power than LED lights.

4. Quality of the Salt Lamp:

The better the quality, the longer you can leave it on before it heats your room and before you have to replace the bulb or tube.

5. Color Your Lamps:

Natural red is best for health and well-being because it mimics sunset color.

6. The Environment in Your Room:

If you have a small, enclosed space that doesn’t get many airflows, such as a large box or trunk, or if there are other heat sources near the lamp, then it may take longer for the salt lamp to cool down after being left on for extended periods of time.

7. Size of the Area:

The larger your room, the longer you can leave it on before it heats up.

8. Ambient Temperature:

If you have a small enclosed space that doesn’t get many airflows, such as a large box or trunk, or if there are other heat sources near the lamp, then it may take longer for the salt lamp to cool down after being left on for extended periods of time.

9. Type of Lighting in the Room:

If you have white lights and a red salt lamp, your eyes will be more prone to stay open later at night because of the combination of blue and red light from the salt lamp. This will lead to more exposure time to blue light from your computer, tablet, and phone screen, which is bad for sleep because it tricks the body into thinking that there’s still daylight outside.

10. Quality of Incandescent Bulbs:

If you use cheap imitations with low-grade filament material (the white part of the incandescent bulb), you will have a higher chance of breaking the salt lamp bulb after using your lamp for extended periods of time.

11. Weather Conditions:

If it is cold with snow, sleet, or frost outside, then your room temperature may be colder than usual, depending on how long you leave the salt lamp on during that day/night.

12. Salt Lamp Wattage:

Using a low-watt salt lamp will take much longer to heat your room than using a high-wattage salt lamp. Higher wattage means the salt lamp can generate more heat on its own.

Can You Leave the Himalayan Salt Lamp on Overnight?

Salt lamps are popular for emitting negative ions, but many people wonder if they can leave a salt lamp on overnight. They’re particularly concerned about leaving candles that go with them burning overnight. On the other hand, some people find it relaxing and soothing to have a soft light while falling asleep or reading a book before sleep. This is relaxing and soothing no matter the light source, whether it’s a tungsten bulb or an LED bulb.

Emitting Negative Ions

Some people turn off all the lights in their house at night but keep one lamp on for safety purposes. So then they could leave one salt lamp burning for soft light while sleeping at night. So the short answer is that you can leave a salt lamp on overnight. But if you want to do this, you should know a few things.

Things To Consider When Leaving Himalayan Salt Lamp Overnight:

  • The salt lamp is made of lightweight, porous pink Himalayan salt that can absorb moisture from the air. Unfortunately, this means a salt lamp can develop moisture inside, eventually making it heavy and unstable on its base.
  • A significant safety issue is created by leaving a candle lighted near the salt lamp overnight. There have been fires that were caused by unattended candles.
  • Many people leave a salt lamp on while they’re sleeping without realizing its potential to explode or crack because of the rapid temperature increase. The heat generated by just a small salt lamp can cause expansion, making it more flammable and unstable if you leave the lid off the lamp, or it can explode if the air temperature in the room is too warm.
  • A salt lamp generates a lot of heat during its first use after being unboxed (typically when you first turn it on). This means you should leave it for several hours while not touching it before touching it.
  • The salt lamp can become very hot, so don’t leave it where a pet or child could touch it and get burned.
  • You should always keep the salt lamp in an area with plenty of air circulation for the first few hours you use it. This will prevent moisture buildup inside the lamp. It will also help to disperse any gases from the production process of the salt lamp.
  • If you have asthma, allergies, or respiratory issues, keep in mind that heat tends to intensify symptoms. So if you’re leaving a salt lamp on overnight for its’ calming effect, then be aware that you may need to reduce your contact with it. This is especially true if heated air from the lamp is trapped in a small room or area with poor air circulation.

Final Thoughts:

In conclusion, if you want to leave your salt lamp on overnight, it is best to have a timer so that the heat doesn’t get too intense and damage any furniture or valuables. It would help if you also made sure there are no animals present in the room (especially cats) as they can knock over lamps and cause injuries.

If you’re not interested in leaving your salt lamp on all night long but still want some of its benefits, try using an aromatherapy diffuser instead! It will provide similar benefits without the risks associated with leaving a hot bulb burning unattended for many hours at a time.
