## How Pressure Affects Parts of the Body While Scuba Diving
When you scuba dive, you’re surrounded by water. Water is much denser than air, so it exerts more pressure on your body. This pressure can have a number of effects on your body, depending on the depth you’re diving and how long you’re down there.
### Ears
The most common problem that scuba divers experience is ear pain. This is caused by the pressure of the water pushing against the eardrum. The eardrum is a thin membrane that separates the outer ear from the middle ear. When the pressure on the eardrum is too great, it can cause pain, discomfort, and even damage.
To prevent ear pain, scuba divers need to equalize the pressure in their ears. This can be done by swallowing, chewing, or using a Valsalva maneuver. The Valsalva maneuver is performed by pinching your nose closed and blowing gently into your ears.
### Sinuses
The sinuses are air-filled cavities in the skull. They are connected to the nose by small passages. When you scuba dive, the pressure of the water can push water into the sinuses. This can cause sinus pain, congestion, and even infection.
To prevent sinus problems, scuba divers need to clear their sinuses before diving. This can be done by blowing your nose gently and using a nasal decongestant.
### Lungs
The lungs are the organs responsible for breathing. When you scuba dive, the pressure of the water can compress your lungs. This can make it difficult to breathe, especially at depths greater than 30 feet.
To prevent lung problems, scuba divers need to breathe slowly and deeply. They should also avoid holding their breath, as this can cause air to become trapped in the lungs and lead to decompression sickness.
### Heart
The heart is the organ responsible for pumping blood throughout the body. When you scuba dive, the pressure of the water can increase the workload on the heart. This can lead to heart problems, such as arrhythmias and heart attacks.
To prevent heart problems, scuba divers need to be in good physical condition and have no history of heart disease. They should also avoid diving at depths greater than 100 feet.
### Skin
The skin is the body’s largest organ. When you scuba dive, the pressure of the water can damage the skin. This can lead to skin irritation, rashes, and even infection.
To prevent skin problems, scuba divers need to wear a wetsuit or drysuit to protect their skin from the water. They should also avoid diving in cold water, as this can cause hypothermia.
### Decompression Sickness
Decompression sickness is a serious condition that can occur when scuba divers ascend too quickly from a dive. When you ascend from a dive, the pressure on your body decreases. This causes nitrogen gas that has been dissolved in your blood and tissues to come out of solution. If the nitrogen gas bubbles form in your body, it can cause decompression sickness.
Symptoms of decompression sickness can include:
Joint pain
Muscle pain
Fatigue
Headache
Nausea
Vomiting
Confusion
Paralysis
Decompression sickness can be fatal if it is not treated promptly. To prevent decompression sickness, scuba divers need to ascend slowly from a dive and make stops at specific depths to allow the nitrogen gas to safely come out of solution.
### Nitrogen Narcosis
Nitrogen narcosis is a condition that can occur when scuba divers dive to depths greater than 100 feet. Nitrogen narcosis is caused by the effects of nitrogen gas on the brain. Symptoms of nitrogen narcosis can include:
Euphoria
Confusion
Hallucinations
Loss of judgment
Impaired coordination
Nitrogen narcosis can be dangerous because it can lead to accidents and even death. To prevent nitrogen narcosis, scuba divers should avoid diving to depths greater than 100 feet.
### Conclusion
Scuba diving is a great way to explore the underwater world. However, it’s important to be aware of the effects of pressure on your body. By taking the proper precautions, you can help prevent problems and enjoy your dives safely.
