What is the first rule of scuba diving?
1. Breathe continuously while on scuba. Never hold your breath.
What should you never do while scuba diving?
Never hold your breath.
This is undoubtedly by far the most crucial of all safety rules for diving because failure to adhere could result in fatality. If you hold your breath underwater at the depths at which scuba divers reach then the fluctuating pressure of air in your lungs can rupture the lung walls.

Why do I need to pee after scuba diving?
Our bodies sense this increase in blood volume in the chest and interpret it as too much blood/water. It sends a signal to our kidneys to get rid of this excess water. Therefore our kidneys produce more urine and we have to pee.
At what age should you stop scuba diving?
After all, according to certifying agencies like PADI, SSI or other scuba diving organizations, there is only one scuba diving age restriction. You can begin to dive when you are 8 years old, and there is no maximum age.
Do sharks mess with scuba divers?
Yes, sharks do attack divers, whether provoked or unprovoked. However, attacks are extremely rare, as sharks do not view scuba divers as a particularly appetizing prey. As such, diving with sharks cannot be considered a dangerous activity, although like everything in life some risks always exist.
Can you cough while scuba diving?
It’s perfectly alright to cough into your regulator until your airway is clear. If you feel that telltale tickle in the back of your throat, try to move into an open area where you won’t bump into anything. Also, be aware of your buoyancy when coughing while scuba diving, as you may unknowingly hold your breath.
What happens if you inhale water while diving?
Once the lungs have inhaled water, this can damage the lung sacs and lead to swelling, which in turn, can disrupt the exchange of oxygen and carbon dioxide, and lead to respiratory distress syndrome hours later. If not treated, it could be fatal.
Do divers have to be skinny?
Diving is an inclusive sport, it can be done by anyone from 13 years old and up regardless of age, weight, or size. So no, it doesn’t matter if you are a very thin person or a fat diver.

Do divers have a lower life expectancy?
D.: Diving is associated with environmental factors that affect the cardiovascular system, and as long as the total amount of physiological stress is limited and the diver is reasonably fit, no data indicate that diving is harmful to the cardiovascular system.
What do divers suffer from?
Nitrogen narcosis: At increasing depths, the partial pressure of nitrogen increases, causing narcosis in all divers. The impairment can be life threatening. This narcosis quickly clears on ascent and is not seen on the surface after a dive, which helps differentiate this condition from AGE.
Who should not scuba?
“If you can reach an exercise intensity of 13 METS (the exertion equivalent of running a 7.5-minute mile), your heart is strong enough for most any exertion,” he says. You also need to be symptom-free. If you have chest pain, lightheadedness or breathlessness during exertion, you should not be diving.
Do divers have bigger lungs?
Several cross-sectional studies have shown that divers frequently have unusually large lung volumes and a lower FEV1/FVC ratio suggestive of obstructive airways disease or airflow limitation.
Do divers have good lungs?
Evidence from experimental deep dives and longitudinal studies suggests long-term adverse effects of diving on the lungs in commercial deep divers, such as the development of small airways disease and accelerated loss of lung function.
Why do so many divers smoke?
Lots of Divers Smoke
There could be a number of factors. They have a lot of spare time. They are also with people on holiday who are treating themselves to a pleasurable experience. Perhaps they feel that smoking is a pleasurable experience that they do not wish to deny themselves in this atmosphere.
Why can’t men breathe in water?
Humans cannot breathe underwater because our lungs do not have enough surface area to absorb enough oxygen from water, and the lining in our lungs is adapted to handle air rather than water.
Do divers breathe 100% oxygen?
Mixed gases
On the deepest working dives, at depths greater than 600 m, ambient pressure is greater than 6100 kPa and the divers breathe gas mixtures containing about 2% oxygen to avoid acute oxygen toxicity.
