Quick Answer
Swimming with heavy clothing in fast water is extremely hazardous and can lead to drowning, exhaustion, or even death due to the increased water resistance and reduced mobility.
Understanding the Risks
Wearing heavy clothing while swimming in fast water increases the risk of being swept downstream. The added weight of the clothing can reduce your buoyancy, making it more difficult to stay afloat. In fast-moving water, even a slight reduction in buoyancy can be fatal.
Calculating the Consequences
According to the American Canoe Association, a person in a wetsuit weighing around 5 pounds (2.3 kg) can be swept downstream by a current of 5 miles per hour (8 km/h) if they are wearing heavy clothing weighing an additional 10 pounds (4.5 kg). In contrast, a person without heavy clothing can swim against a current of up to 3 miles per hour (4.8 km/h) without exhausting themselves.
Safety Precautions
If you must swim in fast-moving water with heavy clothing, wear a properly fitting life jacket to help stay afloat. Avoid swimming alone and inform someone about your location and planned route. Consider wearing shoes with a good grip to avoid slipping on rocks or other underwater obstacles.
