There are few things in life as soothing and relaxing as the warm glow of a campfire,and a Himalayan salt lamp offers a similar ambiance at home.

我以前说过我如何使用它们来保持空气清新以及它们令人舒缓的红光。盐灯在过去几年里已经流行起来,以及一些关于他们利益的爆炸性声明。在本文中,I'll break down the well-studied benefits,the anecdotal ones,为什么每个人都喜欢这些灯呢?

TIP:If you're just looking for a high quality salt lamp for your home (and don't care about the science),I havethis one on my desk right now and love it.


Salt lamps or HPS (Himalayan Pink Salt) lamps are large pieces of pure Himalayan Salt with a small bulb inside.They can be solid pieces of salt (像这样) or decorative baskets filled with large crystals of salt (像这样).他们提供了一个良好的温暖的辉光时,点燃,可能有利于室内空气质量。

Himalayan salt lamps are made from pure,食品级,Himalayan salt crystals.True Himalayan Salt comes from the western side of the Himalayan Mountains in the Punjab region of Pakistan.一旦开采,这盐是手工雕刻成灯或powdered to use as salt in recipes.


Regular table salt is primarily just sodium chloride.喜马拉雅盐仍然是大约98%的氯化钠,but also contains trace minerals like magnesium,potassium,and zinc.微量矿物质使盐灯呈现出它们的色调,范围从浅粉色到深橙色/粉色。




How Does a Himalayan Salt Lamp Work?

Good question!We know the body needs salt for things like hydration,电解质平衡,proper blood pressure regulation and for the nervous system.But all of these benefits come from consuming the salt internally (which I also do).


因为空气中的水也含有过敏原,pollutants and even bacteria,these substances get attracted to the lamp too.The heated salt lamp supposedly dries out the water vapor,把微粒留在盐上。因此,许多消息人士建议每周用布擦几次盐灯来清洁它。


Do Salt Lamps Really Generate Negative Ions?

许多来源声称,盐灯是天然负离子发生器,although there are some important points to understand:


在任何给定时间,there are both positive and negative ions in the air.As a flashback to freshman science class:


带正电的离子也被称为阳离子,while negatively charged ions are anions.正电荷或负电荷使离子容易移动和结合。

Negative Ions in Nature

负离子在自然界中出现的频率更高,它们通常是由闪电风暴等物质产生的。sunlight,waterfalls,还有海浪。Running water is considered nature's greatest source of negative ionsand may be one of the things that contributes to the refreshing scent of waterfalls and the beach.事实上,this is one of the reasons people often report feeling renewed or refreshed after a storm or after spending time at the beach.


一般来说,negative ions increase the flow of oxygen to the brain;resulting in higher alertness,减少嗜睡,还有更多的精神能量。霍华德,PhD,《大脑用户手册:大脑研究的日常应用》的作者,夏洛特应用认知科学中心研究主任,北卡罗来纳州

"They also may protect against germs in the air,resulting in decreased irritation due to inhaling various particles that make you sneeze,cough,or have a throat irritation."

And for a whopping one in three of us who are sensitive to their effects,负离子会让我们感觉像在空中行走。当你打开窗户呼吸新鲜空气时,如果你立刻感到精神振奋,你就是其中之一,潮湿的空气。

Places like waterfalls and beaches where negative ions are naturally produced can have a negative ion concentration of up to 10,000 negative ions per cubic centimeter whereas busy cities can have negative ion levels as low as 100 ions per cubic centimeter.

But,Do Salt Lamps Generate Negative Ions?

简短回答:是的。But not in large amounts.

在大自然中度过时光,especially around water,is definitely the best way to get exposure to negative ions,但是,盐灯也会产生少量,尤其是长期使用时。

Since positive ions are often created by electronic devices like computers,TVs,微波,甚至吸尘器,they can often exacerbate problems like allergies,压力和睡眠问题。Negative ions can neutralize positive ions (they bond together) and help cleanse the air.此外,盐灯提供了许多人觉得放松的舒缓的辉光。

我我个人不严格使用盐灯作为负离子发生器,但是把它们放在房子周围,especially near electronics. If negative ions are the goal,使用a negative ion generatorwould be a much more concentrated source.

Salt Lamps ARE Hygroscopic

正如我上面所说,all salt,by its nature,is吸湿的,meaning that it attracts water to its surface.在喜马拉雅盐台灯里,由于光源发出的热量很小,水分蒸发得很快(这也是为什么盐灯在潮湿气候下容易出汗和变湿的原因)。

Small amounts of water vapor is present in the air and can carry things like mold,细菌,还有过敏原。盐灯会吸收这些水蒸气和它携带到表面的东西,并将它们从空气中去除。当水蒸气蒸发时,this MAY generate a small amount of negative ions.

盐灯产生负离子的理论尚未得到验证或充分研究。That said,it is likely that due to the hygroscopic nature of salt,这些灯对空气质量有积极的影响。




喜马拉雅盐灯有利于清洁空气和减少过敏。 研究表明,不同颜色的光以不同的方式影响身体。我自己的医生推荐avoiding blue light after sunset因为它会干扰昼夜节律,扰乱睡眠激素。

不幸的是,many modern light sources like cell phones,平板,计算机,电视发出很多蓝光,我们中的许多人大部分时间都盯着这些屏幕看,especially in the evening.

盐灯,on the other hand,提供温暖的橙色光芒,similar to the orange hues found in a campfire or by candlelight.因此,它们是晚上的好光源,甚至可以用作夜间照明,而不会对睡眠产生负面影响。

I often wear orange sunglasses at night如果我在电脑上或者看电影来避开蓝光,and we use mostly salt lamps and other low and orange lights after dark for mood lighting.

2。May Improve Air Quality

如上所述,盐灯并不是一种壮观的负离子源。However,由于它们的吸湿性,它们可以通过其他方式改善空气质量。Besides offering a soothing glow,它们可以吸引空气中的污染物,甚至有助于中和电子设备的影响。

3.Light and Color Therapy Benefits

这些舒缓的灯也有助于提高情绪和能量水平,especially for those with季节性情感障碍(SAD).The soft orange hues are one of the soothing colors often used to calm mood and increase focus.少量负离子may also be helpful in boosting mood as well.But,如果你在寻找负离子的好处,spend some time outside instead!





在家里的大多数房间里,我们都有盐灯,在冬天的几个月里,当我们无法打开窗户或在外面花那么多时间的时候,我们就可以享受盐灯。我们现在有一个solid salt lampand a篮灯in several rooms of our home and I love them for their ambient glow and orange color.

Salt lamps cost less than many other types of lamps,一个高质量的可以持续几十年。

如果你想在家里添一盏盐灯,choose ones with these features for best quality:

  1. 橙色–通常认为颜色较深的灯质量较高。Lamps should specify that they are 100% Himalayan salt,因为便宜的仿制品可能使用低质量的盐。
  2. Size– The bigger the salt lamp,the bigger the affect.小灯重5-6磅,大灯重50磅。Smaller lamps are typically much less expensive,so we keep 1 or 2 in smaller rooms and 2 or 3 in larger rooms of our home.
  3. Rough Surface– The surface area of a salt lamp determines its hygroscopic potential.Rougher lamps have a higher surface area than smooth and polished lamps and are more effective at improving air quality.In my opinion,they also look better and are a great decoration for most rooms.
  4. Bulb– The hygroscopic benefits are due to the salt and heat together so it is important to use a heat-producing bulb.LED灯泡不能做到这一点。我用这些便宜的灯泡.

These are a few of the Himalayan Salt Lamps I've tried that meet these criteria:

Himalayan Salt Lamp Benefits: Bottom Line

盐灯不是万能药,也不能取代优质空气过滤器.They don't create large amounts of negative ions like you'll find in nature,especially around water.If negative ions are the goal,在大自然中远足或游泳是一种更有效的方法。

Himalayan salt lamps are a beautiful light source that may offer the benefits of color therapy,通过吸湿清洁空气和减轻过敏。它们是一种廉价的无蓝光光源,可以在天黑后使用,也可以作为儿童的睡眠友好型夜灯。

一天结束的时候,they aren't going to fix any health problems on their own or drastically improve indoor air quality.They are,however,一种漂亮的环保光源,能产生健康的光谱。If you are choosing lamps for your home,they are a great option to consider.
