Hidden Dangers in Hot Tubs

A relaxing soak may turn risky.

It’s easy to assume that luxury means safety, but hot tub and pool dangers often lurk where you least expect. According to the CDC, up to 18,000 Americans are hospitalized yearly for Legionnaires’ Disease. This severe pneumonia is caused by inhaling vapor or mist from contaminated water, including pools and hot tubs.

Bacteria thrive in warm, moist places.

Legionella bacteria flourish in warm water, especially when poorly maintained. While it’s rare for a traveler to contract an infection, the risk increases when pools or spas aren’t properly cleaned. Even decorative fountains and cooling towers have caused outbreaks, proving the danger is more widespread than many realize.

Simple checks can protect your health.

Before stepping in, scrutinize the water. Is it clear or cloudy? A quick test is to toss in a coin—can you read the face? Trust your nose, too. Strong chemical odors could indicate poor ventilation or excessive chlorine, both of which can harm your lungs. Also, check for any slimy residue on the surface or sides.

Chlorine helps, but doesn’t solve everything.

While chlorine disinfects, it must be carefully balanced. Overexposure can harm children or individuals with sensitive skin or respiratory issues. Always shower before and after soaking. If you have kids, consult your pediatrician about chlorine safety and water hygiene best practices when traveling.

Ask challenging questions before dipping in.

The CDC recommends asking the hotel or spa specific questions. Begin with the most recent health inspection score. Then inquire if they check pH and disinfectant levels at least twice daily, or more frequently when the facility is crowded. These details matter, especially in facilities that cater to high-end guests who expect safe environments.

Biofilm buildup can be deadly.

Biofilm is that slimy film that clings to surfaces. If not scrubbed away regularly, it protects bacteria from the effects of disinfectants. Ask if staff routinely clean the tub, replace water filters, and completely change the water on schedule. These steps are not optional—they’re critical for preventing hot tub and pool dangers.

Safety begins with awareness.

Luxury shouldn’t equal blind trust. Hot tub and pool dangers remain real, even in top-tier resorts. Always ask questions, inspect facilities, and prioritize your health. After all, prevention is cheaper—and safer—than treatment.
