What Causes Ear and Sinus Pressure?

Snorkeling is not only a floating activity on the surface of the water, it includes a series of skills such as floating, diving, ascending, draining, ventilating, breathing, self-rescue, and equipment selection. A coach and a series of courses are required to educate and practice, and many skills must be practiced in consideration of dangerous situations.

Snorkeling

Snorkeling is not only a floating activity on the water surface, it includes floating, diving, ascent, drainage, ventilation,
Snorkeling is
1. Gloves: Because hands often touch reefs or creatures, gloves can provide adequate protection;
2. Diving shoes: like the seashore of the south, sea urchins, etc.
The practice of draining the mask must first assume that the mask is flooded to avoid the potential danger of water splashing. In addition, cramps due to improper use of fins may also cause drowning. Therefore, you should hire a professional coach to guide you in the skills practice, so as to minimize the accident rate during the activity. As for snorkeling skills, they can be divided into:
The weight of the water makes the pressure deeper in the water relatively large. As long as it is submerged into the water for a meter, it will immediately feel pain in the eardrum. That is because the pressure in the water is greater than the pressure in the inner ear space. Concavity causes pain. In addition to the ear sinus in the ear, there will be natural gas spaces in the nasal cavity such as the sinuses and the lungs. Want to avoid these uncomfortable or even painful squeezes while snorkeling. Just add some pressure to these natural cavities.

Water-inflating techniques for life jackets: The gas from life jackets should be drained before each dive. Reduce buoyancy to dive to the bottom. However, it takes a short time to rest and adjust your breathing after rising to the surface. If there is not enough buoyancy, you must always kick your fins to maintain buoyancy. Therefore, the inflatable technique of the surface life jacket is very important. First, hold the mouthpiece of the life jacket in your left hand and open the inflation valve. At this time, the fin shoe kicking method must be changed. There will be an impulse to rush out of the water surface. With the time of rushing out of the water, open your mouth to inhale, and your body will fall back into the water and then blow into the life jacket. This way, the air in the life jacket will generate a large amount of buoyancy. It is not to bite the breathing tube when doing this action.
The use of fins can increase swimming speed, but sometimes it becomes a burden. When standing in a flat position in shallow water, for example, resistance will be created so that your feet cannot step forward and cannot stand. The standing technique is very simple, as long as you lie flat on your body and turn your back to the water, then bend and bend your knees to stand. Normally, your back is facing the shore, and you must walk backwards because it is normal. The way forward is easy to fall and get hurt by the hindrance of the fins. Water activities have some potential dangers. To avoid these dangers, we must rely on equipment skills and a correct understanding of the ocean. Therefore, snorkeling needs education and training, and it is not as simple and harmless as people think.
