Is it OK to scuba dive with a cold?

Any diver, proud to be so, knows ears, nose, and lungs have to work properly, otherwise, it could be an important drawback. Diving with a cold would not allow you to compensate during the descend. On the other hand, reverse-compression could happen on the way back up. So, diving with a cold is not recommended.

Can I dive with a runny nose?

Your symptoms can be just like a severe head cold — runny nose, sneezing, coughing and fatigue. If you are suffering from an acute episode due to hay fever, the recommendation is the same as a head cold, and you should not dive.

Can I scuba dive with a stuffy nose?

It's always best not to dive with a cold or any condition that may block the sinus air passages. If you experience difficulties during descent, this is the time to abort the dive. Remember that you can only abort a descent, never an ascent.

Can I scuba dive with a cough?

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.

Can you scuba dive with a chest infection?

During this time there may also be excessive mucus in the airways, which could cause gas-trapping during ascent. Because of this, diving physicians recommend that diving should be postponed after a respiratory infection until all symptoms, including cough, have completely resolved.

How do you get rid of congestion before diving?

Nasal Saline Spray

Make sure to read the bottle and verify that it is natural saline spray and that it is free of any medications. A couple of squirts up each nostril before you dive may irrigate your sinuses enough to provide relief and allow you to equalize them efficiently.

Can you scuba dive with bronchitis?

Furthermore, it can lead to a bacterial pneumonia. For a diver, the optimal function of the pulmonary system is of paramount importance to his or her safety and ability to dive. At no time should an individual with bronchitis dive without first being treated and cleared by an appropriate diving medical officer.

Can I dive with sinus infection?

Divers with recurrent sinus barotrauma should be advised not to dive with a congested nasal cavity (e.g., during an upper respiratory infection or during an episode of either allergic or nonallergic rhinitis).

Is scuba diving good for your 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.

What is the golden rule of scuba diving?

1. 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.

What happens if you fart while scuba diving?

Farting is possible while scuba diving but not advisable because: Diving wetsuits are very expensive and the explosive force of an underwater fart will rip a hole in your wetsuit. An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness.

What is the number one rule of scuba diving?

1. Breathe continuously while on scuba. Never hold your breath. There is no way, you would have missed that one.

Why do you have to jump in backwards when scuba diving?

The Backward Roll Helps Keep Boats Stable

While these boats may have a low center of gravity, a few divers standing on the gunwale will shake things up on board. By entering the water with a backwards fall, you minimize this rocking motion for everyone else on board.

Why do divers spit in their masks?

Decreasing the surface tension and creating a moisture film prevents fogging. So how does Spit help? Saliva acts as a surfactant. Surfactants are wetting agents that lower the surface tension of a liquid, allowing easier spreading.

Why do scuba divers wear snorkels?

By breathing through the snorkel, you'll avoid swallowing lungfuls of water and emptying your dive tank. A snorkel can help you assess dive conditions from the surface. If you're on a dive boat, you could get into the water first while wearing your mask and snorkel to assess the current and level of visibility.

What depth can you get decompression sickness?

Nitrogen narcosis symptoms tend to start once a diver reaches a depth of about 100 feet. They don't get worse unless that diver swims deeper. Symptoms start to become more serious at a depth of about 300 feet. Once a diver returns to the water's surface, the symptoms usually go away within a few minutes.

At what age should you stop scuba diving?

In the US, there is no maximum age limit for scuba-diving. Those over age sixty-five, however, should be in good physical condition before they dive. A detailed medical exam will provide you with information as to whether or not you are physically fit enough for scuba.

What should you not do before scuba diving?

What should you not do after scuba diving?

Why do the divers shower?

Showering helps keep muscles loose between dives, meaning they are less likely to cramp up or become stiff when they enter the pool, or mid-rotation. This is the same reason divers sometime sit in hot tubs between dives – it helps keep their muscles relaxed and supple.

Can a fat person scuba dive?

Can I dive if I am obese? If you are overweight or obese it is strongly recommended that you see a diving doctor before undertaking any diving activity. It is likely that you will be required to have a face to face medical where many factors other than your weight (such as cardiovascular fitness) will be considered.

Do you burn calories scuba diving?

As a rough guide scuba diving can use from 400 to 700 calories each hour. The actual number of calories burned can change due to different conditions – such as water temperature, currents, and the amount of exercise carried out during the dive.

Does diving shorten life?

Ingrid Eftedal, Ph. 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.

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.

Does scuba diving affect life insurance?

Recreational scuba diving won't impact your life insurance policy, but habitual or professional scuba divers will have to pay a flat extra on top of their premium.
