22 Surprisingly Dangerous Things People Treat As Completely Safe

Sometimes, the most dangerous things are those we least suspect and treat as perfectly safe.



Piñatas, a staple at many festive gatherings, can surprisingly pose serious risks. 

Hospital staff often see children with severe brain injuries or head trauma from being accidentally struck by swinging piñata sticks. What’s intended as playful fun can quickly turn into a risky activity without careful supervision.



Dense crowds can be more hazardous than one might expect. 

Once you’re stuck in a mass of people, escaping quickly becomes difficult. This makes it easy for theft or physical attacks to occur undetected. Moreover, a small trigger can turn a peaceful gathering into a dangerous stampede, potentially leading to fatalities due to suffocation in the chaos.



It’s easy to overlook the effects stimulants and sleep aids can have on our health. It might get you through that college paper, but it can be extremely dangerous for your heart. The rollercoaster from high energy to sudden sleep can be a real shock to the system. 

For those who have experienced it, even a small cup of coffee years later might bring back a rush of anxiety and palpitations. A little decaf, anyone?

Standing on a Numb Foot


It might sound trivial, but standing up on a foot that’s “asleep” can unexpectedly lead to serious injuries, including broken bones. 

This often-overlooked issue was personally experienced by many who were unaware of the risk until it was too late.

Natural Gas


Natural gas leaks are a significant hazard often underestimated by many homeowners. 

The inconvenience of repairing a gas appliance might seem bothersome and costly, but the risks of ignoring such issues are far greater. A faulty appliance can lead to catastrophic accidents like explosions.

Cat Bites


While cats are beloved fluffy pets, their bites and scratches can pose serious health risks. Many people underestimate these injuries, but the consequences can be dire, including severe infections that might lead to limb loss or even death. 

Cat scratches, particularly those involving contact with litter, also carry risks due to the bacteria they can spread.

Germs from Mild Illnesses


People often trivialize the risks of spreading mild illnesses like the common cold, not realizing how dangerous they can be to those with weakened immune systems. 

Children can be especially prolific spreaders of germs, highlighting the need for vigilant hygiene practices to protect the vulnerable.



Loneliness is a serious health risk that’s gaining global attention and is recognized by the World Health Organization (WHO).

Described by health authorities as having effects comparable to smoking up to 15 cigarettes a day, loneliness can increase the likelihood of dementia by 50% and heart disease or stroke by 30%. It affects all ages and demographics globally, posing a significant challenge for public health.

Mosquitoes Bites


Mosquitoes are often just an annoyance, but they can also be deadly carriers of diseases like the West Nile Virus. Mosquito bites can lead to a variety of symptoms, often starting mild but potentially escalating to severe conditions. 

Initial signs might include fever, headache, sore throat, abdominal pain, muscle aches, swollen lymph nodes, and rash. As the disease progresses, symptoms can become more severe, including high fever and severe headache, disorientation and coma, vision loss, tremors, convulsions, and muscle weakness.

Metal Grill Brushes


Using metal grill brushes might clean your grill effectively, but they can leave behind dangerous bristles that could end up in your food. These tiny metal pieces can cause severe internal damage or infections if ingested, and they don’t simply dissolve away. 

  • Pro tip: Alternatives like wooden paddles for cleaning grills are much safer and can prevent such hazardous incidents.

DIY Electrical Repairs


Tackling home electrical projects might seem like a cost-effective solution, but without proper training and precautions, it’s a risky endeavor. Faulty wiring can lead to fires, electric shocks, and other dangerous outcomes. 

It’s safer (and often more cost-effective in the long run) to hire a professional electrician for significant electrical work.

Jet Skis


Jet skiing might seem like fun, but it comes with its own set of dangers, particularly from the powerful water jet. 

Injuries from falling off the back can be severe, with the water jet capable of causing serious harm to sensitive areas, including internal damage. It’s a risk that’s rarely discussed, making awareness all the more critical for enthusiasts.

Co-Sleeping with Babies


It’s natural for exhausted parents to want their newborn close at night, especially when every minute of sleep counts. However, the convenience of co-sleeping can come with a heavy price—accidental smothering remains a leading cause of infant deaths. A safer alternative is a co-sleeper crib. It offers the closeness parents crave without the risks (and maybe a bit more sleep!).

  • Did you know? China accounts for 28% of the unintentional suffocation deaths among children under 1 year of age globally.

Football and Hockey

Contact sports like football and hockey are thrilling to watch and play, but they come with significant health risks that can extend far into an athlete’s retirement. 

Concussions and traumatic brain injuries are common, with long-term effects potentially including arthritis, cardiac events, and severe neurological conditions. 

Unsecured Dogs in Cars


Dogs that are not secured in moving vehicles pose a risk to themselves and all passengers. In the event of a crash, an unsecured pet can turn into a dangerous projectile. 

Investing in a basic vest harness and dog seatbelt is a small but life-saving tip to protect everyone in the car.

Ice on Lakes


Venturing onto a frozen lake might seem like a winter wonderland activity, but it carries significant risks. Ice thickness can be deceptive, and just because a lake appears solid doesn’t guarantee it’s safe to walk or ride on. 

Escaping from beneath ice is far more challenging than it appears on TV, and even if one manages to get out, the risk of hypothermia is high, which can be fatal without proper intervention.

Over-the-Counter Pain Medication


It’s easy to assume that over-the-counter (OTC) medications are completely safe, but excessive or improper use can lead to serious health issues, such as liver damage, gastrointestinal problems, addiction, and even death. 

In the United States, the issue of prescription painkiller overdoses is a significant and escalating problem, particularly among women. Data reveals that about 18 women die each day from an overdose of prescription painkillers, totaling more than 6,600 deaths in 2010 alone. Always adhering to the recommended dosages and consulting with a healthcare provider for long-term use is essential to prevent harmful effects.

Metal Rakes


Metal rakes might seem harmless enough, but leaving one hidden under leaves can lead to painful accidents. 

A rake might completely get pierced through your foot when stepping on it (even while wearing flip-flops)—a far cry from the harmless slapstick of cartoons.



Using a treadmill without attaching the safety clip is a common oversight that can lead to nasty falls and severe skin injuries. One incident of slipping can result in painful abrasions from the moving belt. 

Consider this your reminder of why the safety clip—which stops the treadmill if you fall—is your best friend at the gym for preventing ugly injuries.

Drowsy Driving


Drowsy driving causes both personal risk and broader societal impacts, including impaired cognition, increased vehicle and workplace accidents, and significant health consequences. 

Tackling this issue is challenging in a society that often prioritizes activity over sufficient rest. Perhaps better sleep should be a priority for all.

Charging Devices Overnight


Leaving devices to charge overnight is routine for many, but it comes with risks, such as overheating and potential fires, especially with older or faulty wiring or devices. 

To minimize risks, it’s advisable to charge devices when you can monitor them and ensure they are away from flammable materials.

Gas Pump


Pumping gas is a routine task for many, but it carries risks of fires if not done carefully. Static electricity is a naturally occurring phenomenon that can occur under various conditions, but it’s more common in cool, dry weather. While it’s not unique to gas stations, the environment there can make static discharge particularly hazardous due to the presence of flammable gasoline vapors.

Before you start pumping gas, touch a metal part of your car or the car door with your bare hand. This simple action discharges any static electricity that might have built up on your body, reducing the risk of igniting a fire. Once you begin to pump gasoline, avoid getting back into your car. Re-entering your vehicle can cause your body to build up static electricity again—stay safe!
