The Bends is an illness that arises from the rapid release of nitrogen gas from the bloodstream and is caused by bubbles forming in the blood and other tissues when a diver ascends to the surface of the ocean too rapidly. It is also referred to as Caisson sickness, decompression sickness (DCS), and Divers’ Disease.
How do you prevent bends?
- Dive and rise slowly in the water, and don’t stay at your deepest depth longer than recommended. …
- Do not fly within 24 hours after diving.
- Don’t drink alcohol before diving.
- Avoid hot tubs, saunas or hot baths after diving.
- Make sure you are well hydrated, well rested and prepared before you scuba dive.
What are the bends and how can they be prevented?
The good news is that you can avoid the bends if you dive smartly. … Breathe normally during a dive. Make sure you are hydrated before a dive. Don’t drink alcohol before or after a dive.
What causes the bends in divers?
Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body’s tissues.
How do free divers avoid the bends?
Free divers really don’t have to worry about decompression sickness (the bends) because they are not breathing compressed air underwater. They are simply taking a breath of air at the surface, descending, and returning to the surface with that same breath of air. Things just go back to normal.
At what depth do the bends start?
How great is the risk? About 40 percent of the bent divers made a single dive with only one ascent. The shallowest depth for a single dive producing bends symptoms was ten feet (three meters), with the bottom time unknown. However, most of the divers made several shallow dives and sometimes multiple ascents.
At what depth do the bends occur?
The Bends/DCS in very simple terms
Anyone who dives deeper than 10 metres (30ft.) while breathing air from a scuba tank is affecting the balance of gases inside the tissues of their body. The deeper you dive, the greater the effect.
Can you fart while diving?
Farting is possible while scuba diving but not advisable because: … An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness. The acoustic wave of the underwater fart explosion can disorient your fellow divers.
What does the bends feel like?
The most common signs and symptoms of the bends include joint pains, fatigue, low back pain, paralysis or numbness of the legs, and weakness or numbness in the arms. Other associated signs and symptoms can include dizziness, confusion, vomiting, ringing in the ears, head or neck pain, and loss of consciousness.
What happens if you fly after diving?
Flying after diving is dangerous because it can trigger DCS, a condition that is expensive to treat and can be fatal. DCS (Decompression Sickness / The Bends) is the most-common, but easily avoidable, scuba diving injury. As already mentioned on this page, divers increase the level of nitrogen in their blood system.
Can decompression sickness go away on its own?
However, In many cases of decompression illness the symptoms are only minor, such as: joint pain, numbness or tingling and muscular weakness. … Sometimes these symptoms remain mild and go away by themselves, however, they often continue to persist or even increase in severity and medical advice will need to be sought.
What happens if you don’t decompress after diving?
If the pressure reduction is sufficient, excess gas may form bubbles, which may lead to decompression sickness, a possibly debilitating or life-threatening condition.
What should you not do after diving?
Things you shouldn’t do after diving
- Fly. Flying after diving is a well-known risk to divers. …
- Drink heavily. There might be nothing better than an ice-cold beer after diving, but drinking alcohol after diving is not recommended. …
- Climb a mountain. Many scuba divers are real adrenaline junkies and love all outdoor sports.

Can you get bends from freediving?
Decompression sickness was originally thought to only occur in scuba diving and working in high-pressure environments. However, research shows that breath-hold diving (freediving) also poses its own risks for developing decompression sickness (DCS), also referred to as being bent or getting the bends.
What is the deepest free dive ever?
Herbert is a multiple World Champion and the current freediving World Record holder named “the Deepest Man on Earth”. This prestigious media-title was given to him when he then set the world record for freediving at an incredible depth of 214 meters (702 ft) in 2007 in the No Limit discipline.
How dangerous is freediving?
The main pressure related risks associated with freediving include barotrauma of the eyes, ears, sinus and lungs, nitrogen narcosis and decompression sickness.
