A calm Saturday on the lake: two friends in rented sit-on-tops, life jackets bungeed to the deck because it’s hot and the water looks flat. Down the river, a whitewater kayaker braces hard with her arm high and feels her shoulder slide out of place. Kayaking covers family floats, youth camps, college club trips, fishing kayaks, sea-kayak expeditions, marathon racing and Olympic sprint, slalom and kayak cross. Most days end with nothing worse than tired arms. When kayakers do get hurt, it’s usually one of the things below.

This page is general information, not medical advice. If you’re hurt, see a sports medicine doctor, physical therapist (PT) or certified athletic trainer (AT). In an emergency on the water, call 911 or the Coast Guard on VHF channel 16. For the big picture, start at our kayaking hub.

Drowning and life jackets: what the Coast Guard data show

The most serious kayaking risk isn’t a sore shoulder. It’s ending up in the water without a life jacket. In the US Coast Guard’s 2024 Recreational Boating Statistics, kayaks accounted for 89 deaths, 77 of them drownings, about 16% of all boating deaths and more than any other kind of paddlecraft.

Craft (USCG 2024)	Deaths	Drownings	Share of deaths from drowning
Kayak	89	77	87%
All recreational boats	556	365	66%

Drowning makes up a bigger share of kayak deaths (87%) than of boating deaths overall (66%): a kayak tips easily and puts you straight into the water. The life jacket data are stark: of the 77 kayakers who drowned in 2024, 60 weren’t wearing a life jacket, 16 were, and one is unknown. Across all boating, where life jacket use was known, 87% of the people who drowned weren’t wearing one. Alcohol was the leading known contributing factor in fatal boating incidents.

• Wear it, don’t stow it. Federal rules require a Coast Guard-approved wearable life jacket for each person on board, the right size and in good condition. A life jacket bungeed to the deck can’t help if you capsize and get separated from the boat. Paddling vests with a high back and big arm openings, like the Onyx MoveVent Dynamic, are made to be comfortable for a full day of strokes.
• Inflatables: the Coast Guard does not recommend inflatable life jackets for anyone under 16 or for non-swimmers. On whitewater, American Whitewater recommends a snug, vest-type foam PFD; Coast Guard-approved whitewater vests rated Performance Level 70 are the most common.
• Paddle sober, and not alone. American Whitewater’s Safety Code strongly discourages alcohol and drugs on river trips and says single-craft outings are a common factor in incidents and drownings.
• Practice getting back in. The Coast Guard notes kayaks tend to be less stable and can easily capsize, and asks: can you climb back in with all your gear on? Practice wet exits from a sit-inside, climbing back onto a sit-on-top, and paddle-float re-entries in warm, shallow water, or take a class.

Cold-water immersion: the 1-10-1 principle

The National Weather Service calls water of 70°F or lower “cold water” and warns that you can lose muscle control within 10 minutes. Physiologist Gordon Giesbrecht’s 1-10-1 principle is an easy way to remember what happens after an unexpected swim:

• 1 minute, cold shock: a sudden gasp and fast, heavy breathing. If your face is under water at that moment, you can breathe in water. Focus on getting your breathing under control.
• 10 minutes, cold incapacitation: over roughly the next 10 minutes your fingers, arms and legs stop working well. Use that time to get back in the boat, onto it, or to shore.
• 1 hour, hypothermia: even in ice water it can take about an hour to lose consciousness from hypothermia, but only if a life jacket is keeping your head up.

Treat the numbers as a memory aid: the National Center for Cold Water Safety notes that cold shock can kill within seconds to two minutes. Dress for the water temperature, not the air. American Whitewater says a wetsuit or drysuit is essential when water is below 50°F, with wool or synthetic layers (never cotton) as the next-best option. In a Coast Guard paddle safety release, the agency encouraged wetsuits or drysuits in water below 65°F. After a cold swim, watch for hypothermia (CDC: shivering, confusion, fumbling hands, slurred speech, drowsiness); below 95°F is an emergency.

Cold also affects hands over a season. In a 2022 survey of 609 paddlers who trained in cold conditions, 23% reported symptoms that fit non-freezing cold injury (pain, numbness or cold sensitivity after long cooling), more often in women, smokers and people with Raynaud’s. Hands that stay numb or painful after paddling deserve a doctor’s look.

Rivers: swimming a rapid, foot entrapment and strainers

American Whitewater’s Safety Code says never try to stand up in fast-moving water: a foot can wedge between rocks and the current can push you under. Swim to slow water, or water below your knees, first. Avoid trees and logs in the current (strainers), which can pin people and boats. Wear a whitewater helmet, and only run rapids you can self-rescue on, ideally with a reliable roll. In one Colorado county, 82% of whitewater drowning victims had little or no whitewater experience.

Shoulder dislocations and other acute shoulder injuries

The shoulder is the body part paddlers hurt most. In a classic survey of 392 whitewater kayakers, the upper extremity, especially the shoulder, was the most injured area, and dislocations made up 17% of injuries; 87% of injuries happened while the paddler was still in the boat. The force of the water travels up the paddle into the arm. In a UK hospital series of 57 shoulder injuries in paddlers, a capsize was the most common cause (26%), and all ten labral tears caused by a capsize needed surgery. The authors found injuries happened most often while bracing to prevent a capsize, during the capsize, or while rolling, when the arm is raised high and rotated back.

• Keep your hands in front of you. Many instructors teach a “paddler’s box”: hands in front of the shoulders, elbows low and bent, especially on high braces and rolls. Learn braces and rolls from a qualified instructor.
• Don’t fight a failed brace with a straight arm overhead, and strengthen the rotator cuff off the water (see kayaking training).

If a shoulder comes out: the American Academy of Orthopaedic Surgeons (AAOS) treats a dislocated shoulder as an emergency injury. Most dislocate forward; signs are deformity, swelling, numbness, weakness and pain. Don’t try to pop it back in yourself; stabilize the arm, get the paddler to shore and to medical care, where doctors put the joint back (a “closed reduction”). Young athletes have a higher chance of it happening again, and some choose surgery after a first dislocation to lower that chance.

Overuse: shoulders, wrists and the low back

Every forward stroke repeats the same motion, thousands of times on a long day. A survey of 583 paddlers at six Australian kayak and surf-ski races found the top paddling injuries over five years were the shoulder (31%), low back (23.5%), wrist (16.5%), neck (13.7%) and elbow (11%). Olympic sprint kayakers show the same pattern: over three years in the Australian national squad, 78% of athletes had at least one injury, with the upper limb making up 48% of injuries and the shoulder 27%.

Shoulder overuse

In one group of 31 Swedish flatwater kayakers, 55% had experienced shoulder pain; those with pain had less inward rotation and poorer shoulder-blade control. MRI scans of 52 marathon kayakers found rotator cuff problems, such as supraspinatus tendinitis and partial tears, among the most common findings, linked to overuse.

Wrist tenosynovitis

Gripping and twisting the shaft can irritate the wrist tendons. At one 5-day kayak marathon in Australia, 42 paddlers came to the medical team with wrist extensor tenosynovitis, and standard care (ice, stretches and massage) appeared to be enough to manage it during competition. A related condition, de Quervain’s tenosynovitis, causes pain on the thumb side of the wrist. Paddlers often reduce the strain with a relaxed grip (open fingers on the push side), a paddle shaft that fits the hand, and building distance gradually.

Low back

The low back was the most injured site in elite teenage flatwater kayakers in a 2025 study, ahead of the shoulder, wrist and knee. Kayakers sit with legs forward for hours, so a good seat and footrest fit, stretch breaks on long trips and trunk strength help; in a 6-month randomized trial of 103 young paddlers, a trunk program improved core strength, low-back control and posture.

Sun, heat and lightning

The American Academy of Dermatology recommends a broad-spectrum, water-resistant sunscreen of SPF 30 or higher, reapplied every two hours and after getting wet, plus sun-protective clothing, a hat and sunglasses. A long-sleeve rash guard like the O’Neill Basic Skins (UPF 50+) covers the arms that are in the sun all day, and a sport lotion such as Blue Lizard Sport SPF 50 covers the rest. On hot, still days, confusion or collapse could be exertional heat stroke: the National Athletic Trainers’ Association (NATA) says cool the person right away, ideally in cold water, and call for help. For lightning, NATA’s rule is “When thunder roars, go indoors”; a boat on open water is not a safe place.

Safety gear many paddlers use

Three items cover the biggest risks on this page: a life jacket you’ll actually wear, a floating radio (the Coast Guard advises two waterproof ways to call for help), and sun protection.

When to get help

• Right away (911 or VHF 16): anyone pulled from the water who isn’t breathing normally, or who coughs, is confused or unusually sleepy afterward; suspected hypothermia; heat stroke; a dislocated shoulder or possible broken bone; a deep cut that won’t stop bleeding; a head injury with danger signs (worsening headache, repeated vomiting, slurred speech, seizures, loss of consciousness).
• Within a day or two: a shoulder that “slipped” and went back on its own, a possible concussion (follow the CDC’s HEADS UP rule: out for the day and until a health care provider clears them; see our soccer injuries page for the return steps), wrist swelling or creaking that doesn’t settle.
• Soon: shoulder, wrist or back pain that keeps coming back after paddling, pain at night, numb or painful hands after cold trips, or a changing mole or skin spot (a dermatologist is the right person for that one).

A sports medicine physician diagnoses; a physical therapist guides rehab and the return to paddling. Between sessions, see kayaking recovery, plan safer days with paddle day and race day, and compare beacons and radios on kayaking wearables. Rowers face similar overuse issues: see rowing injuries. Canoeists have their own page: canoeing injuries.

Kayaking injuries: FAQs

What is the most common kayaking injury?

Shoulder injuries, in nearly every study, from whitewater surveys to Olympic sprint squads. Low back, wrist, neck and elbow problems follow. Recreational paddlers also get cuts, bruises and sprains, often getting in and out of the boat or carrying it.

How many people die kayaking each year in the US?

The Coast Guard counted 89 kayak deaths in 2024, 77 of them drownings, and 60 of those 77 kayakers weren’t wearing a life jacket. Kayaks made up about 16% of all US boating deaths that year.

Do I need a wetsuit or drysuit for kayaking?

Dress for the water temperature, not the air. American Whitewater calls a wetsuit or drysuit essential below 50°F, and the Coast Guard has encouraged them for paddlers in water below 65°F. The National Weather Service treats anything 70°F or lower as cold water.

How do I avoid a dislocated shoulder in a kayak?

Learn braces and rolls from an instructor, keep your elbows low and hands in front of your shoulders, and don’t fight a capsize with a straight arm overhead. Shoulder strength work off the water helps too. If a shoulder does come out, it’s an emergency: don’t try to put it back yourself.
