Fireworks are widely associated with celebration and spectacle, yet behind their bright colours and loud explosions lie significant health risks that are often underestimated.
These risks affect not only those who handle fireworks directly, but also spectators, nearby communities, animals, and emergency responders. Understanding these dangers is essential for making informed decisions about their use and for promoting safer alternatives.
One of the most immediate health risks of fireworks is physical injury. Burns are the most common, ranging from minor skin damage to severe, life-threatening trauma. Fireworks can explode unpredictably, causing injuries to the hands, face, eyes, and ears.
Eye injuries are particularly serious, as fragments or sparks can lead to permanent vision loss.
Small fireworks such as sparklers also carry risks, and are believed to be responsible for starting the fire at a Swedish ski resort recently, killing forty people and injuring many others.
With large fireworks, even bystanders at a safe-seeming distance are at risk from misfires or falling debris. Children are especially vulnerable, both because of curiosity and because their smaller bodies are more susceptible to harm.
Noise-related health impacts are another major concern. Fireworks can reach noise levels well above 140 decibels, comparable to gunfire. Exposure to such intense sound, even briefly, can cause temporary or permanent hearing damage.
For individuals with pre-existing hearing issues, tinnitus, or sensory sensitivities, fireworks can be painful and disorienting. Infants and young children are at particular risk because their ears are still developing, and they may not be able to communicate discomfort effectively.
Pollution
Fireworks also pose significant respiratory and cardiovascular risks due to air pollution. The smoke released contains fine particulate matter (PM2.5), heavy metals, and chemical compounds used to produce colours and effects. Short-term exposure can irritate the lungs, trigger asthma attacks, and worsen conditions such as bronchitis or chronic obstructive pulmonary disease (COPD).
Studies have shown spikes in hospital admissions for respiratory and heart problems following major fireworks displays, especially among older adults and people with underlying health conditions.
Mental health impacts shouldn’t be overlooked. Loud, unexpected explosions can cause anxiety, stress, and panic, particularly in individuals with post-traumatic stress disorder (PTSD), autism spectrum conditions, or anxiety disorders.
For some, fireworks can trigger flashbacks or intense distress that lasts well beyond the event itself. Sleep disruption caused by late-night displays can also affect mental wellbeing, especially when fireworks are used over multiple days.
Beyond human health, fireworks indirectly affect wellbeing by impacting animals and the environment. Pets and wildlife often experience extreme fear, leading to injuries, escape, or even death.
Environmental contamination from debris and chemicals can enter water and soil, contributing to longer-term ecological harm that ultimately feeds back into human health.
Because of all the above issues, the Netherlands has just decided to ban fireworks.
Australian regulations around fireworks have tightened in most jurisdictions in recent years, at least for personal use, but large public fireworks displays in most cities have become even more entrenched, at times such as New Year’s Eve.
While fireworks are culturally significant and visually impressive, they carry real and sometimes serious health risks.
Reducing these risks through regulation, public education, protective measures, and consideration of quieter or alternative forms of celebration can help protect everyone while still allowing communities to mark special occasions safely.
