Camphor vs naphthalene balls: Which one is safer for your health?

Most homes have used either camphor or naphthalene balls at some point. You open an old cupboard, and that sharp, familiar smell hits you instantly. Clothes stored for months. Corners no one checks often. And the simple hope that insects, moisture, and musty smells will stay away. But somewhere along the way, a question quietly comes up. Are these things actually safe for us?Because what keeps insects away also ends up staying in our living space. And that matters more than we realise.Camphor and naphthalene balls both serve the same purpose in most households. They’re meant to repel insects, especially moths, and keep stored clothes from smelling stale. They work by slowly turning from solid to gas. That strong smell is what insects hate. But humans breathe that air too. And that’s where the health conversation begins.For years, these balls were treated as harmless household staples. Cheap, effective, and widely available. No one questioned them. But over time, doctors and health experts started noticing patterns. Headaches. Breathing discomfort. Nausea. And in some cases, more serious reactions, especially in children.Let’s start with naphthalene balls because they’ve been around forever. They’re made from a chemical called naphthalene, which easily evaporates into the air. That’s why the smell is so strong and long-lasting.The problem is that naphthalene fumes are toxic when inhaled over time. Short exposure can cause headaches, dizziness, and nausea. Longer exposure can irritate the lungs and eyes. In children, it can be especially dangerous. Accidental ingestion has led to serious poisoning cases. Even skin contact over long periods isn’t ideal.And here’s something many people don’t realise. Naphthalene doesn’t stay limited to cupboards. The fumes travel. They spread into the room, especially in small homes or poorly ventilated spaces. So even if you think you’re using it carefully, your body is still exposed.That’s why many health experts now strongly advise against using naphthalene balls inside homes. Not because they don’t work, but because the cost to health is simply too high.Camphor often feels like the safer choice. It comes from the camphor tree, sounds natural, and has been used in traditional practices for generations. And yes, compared to naphthalene, camphor is less toxic. But less toxic doesn’t mean completely safe.Camphor also releases strong fumes. In small amounts and well-ventilated spaces, most adults tolerate it without problems. But prolonged exposure can cause headaches, nausea, and irritation of the nose and throat. For people with asthma or respiratory sensitivity, even camphor fumes can trigger discomfort.And then there’s children again. Camphor ingestion is dangerous. Even small quantities can cause vomiting, confusion, or seizures. That’s why camphor should never be left within reach of kids, no matter how “natural” it sounds.So while camphor is safer than naphthalene, it still needs caution.One common assumption is that if something smells strong, it’s doing its job. That’s true for insects. But for humans, strong smells are often warning signs. Your nose reacts for a reason. Headaches after opening a cupboard. A slight burning sensation in the nose. That heaviness in the head. These aren’t random.Both camphor and naphthalene work by releasing chemicals into the air. The difference is how toxic those chemicals are. Naphthalene is clearly more harmful. Camphor sits in a grey zone. Safer, yes. But still not something to overuse.And storing them inside closed cupboards only increases exposure because the gas builds up and gets released all at once when you open the door.The real concern isn’t one-time use. It’s repeated exposure over months and years. That’s when subtle symptoms start creeping in. Frequent headaches. Irritated eyes. Unexplained fatigue. People rarely connect these to something sitting quietly in a cupboard.Indoor air quality matters. We spend a lot of time indoors. And small chemical sources add up. One mothball here. One strong cleaner there. Incense, room fresheners, mosquito repellents. Together, they create a chemical load the body has to deal with.So choosing the lesser evil, or better still, choosing safer alternatives, becomes important.Household habits don’t change overnight. Many of us use what we grew up seeing. But health awareness evolves. What once felt normal may no longer be the safest choice.If you must choose between the two, camphor wins. But using smaller amounts, ensuring airflow, and not keeping it permanently inside cupboards makes a big difference. Even better is slowly reducing dependence on both and relying more on cleanliness, dryness, and regular airing.Your home should protect your health, not quietly challenge it.And sometimes, that starts with questioning the smallest things. Even something as ordinary as a mothball.
