Can you scuba dive with bad lungs?
For individuals with any lung condition that has an increased risk of pulmonary barotrauma, diving physicians recommend that they avoid scuba diving.
Does scuba diving make your lungs stronger?
With breath-hold diving, total lung volume will decrease with increasing depth or ambient pressure, due to Boyle’s law. The pressure and density of the gas inside the lungs will increase accordingly.

When should you not scuba dive?
If you’re generally fit and healthy, there should be no problem. You will be required to sign a medical statement before learning to dive. If you’re already certified to dive, avoid diving if you’re not feeling one hundred percent. In particular, don’t dive if you’ve got a head cold or a hangover.
When should you not dive?
The general rule that seems to be widely agreed upon is that you should wait 12 hours after a single no-decompression dive, 18 hours after multiple dives or multiple days of diving and at least 24 hours after dives requiring decompression stops.
At what depth will your lungs collapse?
If one descends to a depth of 100 feet (about 30 metres), the lung shrinks to about one-fourth its size at the surface. Excessive compression of the lungs in this manner causes tightness and pain in the thoracic cavity.
What does scuba diving do to your lungs?
As you ascend, water pressure decreases, and the air in your lungs expands. This can make the air sacs in your lungs rupture and make it hard for you to breathe. If air bubbles get into an artery, they can cause a blockage that affects your organs. The blockage is called an arterial gas embolism.
What are the side effects of scuba diving?
Diving does entail some risk. Not to frighten you, but these risks include decompression sickness (DCS, the “bends”), arterial air embolism, and of course drowning. There are also effects of diving, such as nitrogen narcosis, that can contribute to the cause of these problems.
How can I improve my scuba diving breath?
The only thing for certain is that the optimum breathing strategy when scuba diving is deep slow breathing. You need to inhale slowly and then also exhale slowly without holding your breath. Develop a pattern that you are comfortable with and that works for your current work load.
Can I go scuba diving if I can’t swim?
The answer is: yes, you can
To get certified as a diver, you need to know basic swimming (ability to float or tread water for 10 min, swim 200m unaided/300m with mask-fins-snorkel). However, to do introductory scuba diving program such as Try Scuba or a PADI Discover Scuba Diving program, swimming is not required.
