The Dead Sea is generally safe to visit, but it requires more caution than a typical beach. Its salt concentration, roughly 10 times higher than the ocean, creates real risks if the water gets in your eyes, mouth, or any open cuts. Most visitors float without incident by following a few straightforward precautions, but ignoring them can lead to serious problems, including hospitalization.
Why the Dead Sea Isn’t Like Other Bodies of Water
The Dead Sea’s salt content hovers around 34%, compared to about 3.5% in the ocean. That extreme salinity is what lets you float effortlessly on the surface, but it also means the water is intensely caustic. It will sting any broken skin, burn your eyes on contact, and cause dangerous electrolyte imbalances if swallowed. You don’t actually swim in the Dead Sea in the traditional sense. Most people float on their backs, keeping their face well above the waterline.
The Biggest Danger: Swallowing the Water
Accidentally swallowing even a small amount of Dead Sea water is the most serious risk. The water is far more concentrated than your blood, with an osmotic pressure more than three times that of normal body fluids. When highly concentrated salt water reaches the lungs or digestive tract, it pulls fluid from surrounding tissue, potentially causing rapid swelling in the lungs, difficulty breathing, and dangerous drops in blood oxygen. Several drowning deaths at the Dead Sea have involved people who inhaled or swallowed the water after falling face-first into it.
This is why you should always float on your back and avoid splashing. If you’re not a confident swimmer or have difficulty controlling your body in the water, stay in the shallows where you can easily stand. Children need close supervision, and many guides recommend keeping very young children out of the water entirely.
What Happens if It Gets in Your Eyes
Getting Dead Sea water in your eyes causes immediate, intense burning. The high mineral concentration acts as a chemical irritant to the delicate surface of the eye. If it happens, you need to rinse your eyes with clean fresh water right away, flushing steadily for at least 15 minutes. Most authorized beaches have freshwater showers and rinse stations nearby for exactly this reason. Bring a sealed bottle of fresh water to the shoreline so you have it within arm’s reach.
Protecting Your Skin
Any cut, scratch, razor nick, or area of raw skin will sting sharply in the Dead Sea. The standard advice is to avoid shaving or waxing for at least two days before your visit, since even tiny nicks you can’t see will announce themselves the moment you enter the water. If you have eczema, cracked skin, or fresh sunburn, expect discomfort.
Interestingly, the Dead Sea’s mineral-rich water and unique climate have documented benefits for certain skin conditions. A four-week treatment program studied at Ein Gedi in Israel showed an 88% reduction in psoriasis severity scores, with over half of patients achieving complete skin clearance. But these programs involve carefully controlled, gradual exposure under medical supervision. Casually soaking with active skin lesions is a different experience and will likely hurt.
Most visitors limit their time in the water to 15 to 20 minutes per session. Staying in longer dries out your skin and increases irritation. Rinse off thoroughly with fresh water afterward, and apply moisturizer. The minerals leave a tight, dry feeling on your skin if you don’t.
Sinkholes and Beach Safety
The Dead Sea has been shrinking for decades, losing roughly a meter of depth per year. As the water recedes, underground salt layers dissolve, creating sinkholes that can open suddenly and without warning. Mineral Beach, a tourist resort on the northern shore, was permanently closed in 2015 after a sinkhole swallowed parts of the property. Highways, bridges, and other beaches along the coast have been shut down for the same reason.
Stick to officially operated, authorized beaches. These are monitored and maintained, with infrastructure like freshwater showers, lifeguards, and marked entry points. Wandering to unmarked stretches of shoreline, no matter how scenic, puts you at real risk of encountering unstable ground. The sinkholes can be meters deep and appear in areas that look completely solid.
Practical Tips for a Safe Visit
- Float on your back. Never put your face in the water. Don’t dive, don’t do handstands, and don’t splash others.
- Bring fresh water to the shore. Keep a sealed bottle at the water’s edge for rinsing your eyes or face immediately if needed.
- Wear water shoes. The lakebed is encrusted with sharp salt crystals that can cut your feet.
- Skip shaving for two days beforehand. Even micro-cuts from a razor will sting intensely.
- Limit your soak to 20 minutes. Longer exposure dries and irritates your skin.
- Remove jewelry. The high mineral content can tarnish or damage metals.
- Stay at authorized beaches only. Sinkhole risk is real along unmonitored stretches of shoreline.
- Shower immediately after. Rinse the salt off your skin and hair with fresh water as soon as you exit.
Who Should Be Extra Cautious
People with open wounds, recent surgical incisions, or active skin infections should avoid the water. The intense salinity isn’t just painful on broken skin; it can worsen inflammation and delay healing. Anyone with heart or kidney conditions should also be cautious, since the minerals absorbed through the skin during prolonged soaking can affect electrolyte balance.
If you wear contact lenses, remove them before entering. A splash of Dead Sea water trapped under a contact lens concentrates the burn directly against your cornea and makes rinsing far more difficult. Prescription swimmers who need vision correction should consider disposable daily lenses they can throw away after, or simply go without.
For most healthy adults, the Dead Sea is a safe and memorable experience. The risks are real but manageable. The key is treating it with more respect than you’d give an ordinary beach, keeping your face dry, staying at maintained sites, and having fresh water close by at all times.
