Dry static apnea implies a form of breath-holding approach for freediving, which is performed specifically on the firm land and excluding any kind of movements. The main purpose of this form of technology is to instruct your mind and body in such a way that it remains calm during the breath-holding process to absorb less oxygen.
Understanding the strengths of dry static apnea
It is safe
If the freediver holds their breath for longer time spans, and forces stuff upto an extent and blackouts in the process, drowning becomes out of the question. Although, it is necessary to perform dry static breath-holds laying down, so you're not going to hit your head or injure yourself if you pass out.
Safe to perform unattended
This is considered as one of the major advantages of doing dry static breath-holds is that you don’t need any diving friends along with you and still perform it safely. Since you are not underwater, so you are at a safer spot and at no risk zone of drowning even if you pass out.
Water bodies are not required
The most crucial and beneficial aspect of dry static breath-hold apnea is that the person doesn't need a water body around you to perform the technique. You can easily just do it anywhere, lying on your bed or the sofa. Thus, making this practice readily available.
Talking about the constraints of dry static apnea
Do not expect it to be very productive
Dry static breath-holding certainly prepares you to deal with apnea's unpleasant impacts. Since, you don't do it underwater, which means it isn't as relevant to freediving. The body will not be as accustomed to underwater freediving as it should be.
Difficult as compared to wet apnea
Freediving is an underwater activity that involves rigorous underwater breathing training. But in the case of dry static apnea, you don't get the benefits of the breath-holding practices while in water, so the outcome is shorter apnea periods.
