The aurora borealis, a celestial curtain of shimmering green and violet light, is a phenomenon that inspires wonder in almost everyone who witnesses it. This breathtaking display, often called the northern lights, prompts a fundamental question for travelers and photographers: is aurora borealis dangerous? The short answer is that the lights themselves are entirely harmless, but the environment required to see them presents specific risks that demand respect and preparation.
Understanding the Science Behind the Display
To assess the danger, it is essential to understand the science of the aurora. This visual spectacle occurs when charged particles from the sun collide with gases in Earth’s atmosphere around 60 to 250 miles above the surface. The energy release happens at such a high altitude that it poses no threat to people on the ground. You are simply observing a reaction similar to a very large, slow-motion neon sign powered by solar wind, and the experience of watching this natural light show is no more dangerous than standing under a common streetlamp.
Primary Risks Are Environmental, Not Visual
The Challenge of Arctic Weather
The most significant danger associated with chasing the aurora is not the light, but the extreme weather conditions found in high-latitude regions. Travelers often underestimate how quickly a clear, calm evening can transform into a freezing storm with wind chills dropping below -30°C or -22°F. Hypothermia and frostbite are genuine threats, making proper layered clothing, insulated boots, and thermal gear absolutely essential for safety.
Navigating Darkness and Terrain
Because the aurora is visible only in the deep darkness of night, often far from urban centers, the risk shifts to the journey itself. Driving on icy roads in the Arctic night requires snow tires or chains and a high tolerance for stress. If you are venturing away from populated areas, you risk getting lost or stranded if your vehicle fails on a remote snow-covered road. Carrying emergency supplies, including blankets, food, water, and a fully charged power bank, is non-negotiable for mitigating this danger.
Photography and Physical Safety
Photographers chasing the perfect shot often place themselves in precarious positions, standing on frozen lakes, rocky shores, or steep embankments. The danger here is purely physical, as the ground can be slippery and unstable after dark. Using a tripod with a wide aperture lens allows for a stable shot without the need to lean over edges. Additionally, the cold drains camera batteries rapidly, so keeping equipment warm in inside pockets and having spares is crucial to avoid being stranded without a means of communication.
Health Considerations and Comfort
While the aurora does not cause illness, the act of observing it can strain the body. Standing still in sub-zero temperatures for hours while waiting for the lights to intensify can lead to stiff muscles and reduced circulation. This physical discomfort can distract from the experience and increase the risk of accident. Taking warm breaks in a vehicle or shelter, staying hydrated, and avoiding alcohol—which accelerates heat loss—are practical strategies to maintain physical health during an aurora hunt.
Technology and Communication
Another layer of risk management is connectivity. Many prime aurora viewing locations lack cellular service, which means that if an emergency arises, help cannot be summoned with a simple phone call. Satellite communicators or personal locator beacons are valuable investments for remote excursions. Furthermore, checking the space weather forecast is vital; a geomagnetic storm that produces a strong aurora display might also disrupt GPS systems and radio communications, adding complexity to navigation.
The Verdict on Safety
Ultimately, the aurora borealis is a safe and passive spectacle. The danger is not found in the lights dancing across the sky, but in the human decisions made to reach that location. A traveler who respects the power of the Arctic cold, prepares for the darkness, and maintains reliable communication will find the experience overwhelmingly safe and spiritually enriching. By prioritizing preparation over panic, the pursuit of the northern lights becomes a rewarding adventure rather than a hazardous undertaking.
