get a oxy tank .
Unless you have gills, you are going to need access to oxygen. There is the traditional snorkeling mask, a Scuba tank, or more recently, a new breathing apparatus that doesn't use tanks or tubes.
"An Israeli Inventor has developed a breathing apparatus that will allow breathing underwater without the assistance of compressed air tanks. This new invention will use the relatively small amounts of air that already exist in water to supply oxygen to both scuba divers and submarines. The invention has already captured the interest of most major diving manufacturers as well as the Israeli Navy."

Humans can adapt to underwater pressure by ascending or descending slowly to allow their bodies to adjust gradually. Divers can also use specialized equipment, such as diving suits and breathing apparatus, to help regulate pressure and minimize the risk of decompression sickness. Proper training and knowledge of diving safety practices are essential for adapting to underwater pressure effectively.
I will give you as much as i know. Humans came from water, far before our current time. You can say we were fish or lived on land and hunted and such underwater, or you can say humans were once mermaids. { Tell me what you think about our weird ability to shrink our pupils underwater, webbing between toes and fingers, and some thing of how our lungs adapt also but i cant remember what it does...It kind of crosses on of those out.} Going underwater as much as possible could cause the body to adapt to it more and maybe then could we go back to the crazy old days of being of the water. I would recommenced starting in a pool then working into the ocean. Who knows what will happen, maybe your body will change, maybe you will waste a large amount of your life. But your lungs WILL change and that is always good :D
A human is under an average pressure of about 14.7 pounds per square inch (psi) at sea level on Earth due to the weight of the atmosphere pressing down on them. This pressure decreases at higher altitudes and increases underwater.
The human body has internal fluids and tissues that balance the pressure exerted by the atmosphere. Our bodies are also designed to adapt to changes in atmospheric pressure to maintain equilibrium. Additionally, we have evolved to withstand atmospheric pressure through anatomical structures like the lungs, which expand and contract to adjust to pressure changes.
An underwater vehicle built to resist pressure is called a submersible. These vehicles are designed to protect passengers and equipment from the immense pressure of deep-sea environments.
Mermaids, being fictional creatures, do not actually exist. However, in folklore and mythology, mermaids are typically portrayed with physical attributes (such as gills or fins) that help them adapt to living in underwater environments. This mythical adaptation allows them to breathe, swim, and thrive in the ocean depths.
Humans can swim without swelling or bursting because the body is designed to maintain a balance of fluids and gases within it. Swelling or bursting can occur when there is a sudden increase in pressure, but the body adapts to changes in pressure when swimming by equalizing the pressure inside and outside the body through various mechanisms, such as the Eustachian tube in the ears to equalize pressure underwater.
Pressure increases underwater because the weight of the water above compresses the water below. The deeper you go, the greater the pressure because there is more water pushing down. This increase in pressure can have physiological effects on the human body, such as affecting breathing and circulation.
i seriously don't know
No, the fluid pressure increases with depth underwater. The pressure at 10 ft underwater will be greater than the pressure at 5 ft underwater due to the weight of the water above exerting a greater force at greater depths.
On average, a person can hear sounds underwater up to a distance of about 60 meters (200 feet). This distance may vary depending on water conditions, such as temperature, pressure, and clarity.

Fish adapt to the pressure.
Monkeys cannot survive underwater, they'd need gills like fish. Since they have lungs they could only survive underwater for a short period of time.
by being cold blooded by having second eyelids and by being able to breath underwater
Without proper equipment no human can breathe underwater anywhere.
The pressure exerted on a diver 10 m underwater is approximately 2 atmospheres or 1.8 times the atmospheric pressure at the surface. This means the pressure is effectively doubled at this depth.
Pressure rating for underwater
An atmosphere meter, or barometer, is a device used to measure atmospheric pressure, which is an important factor in determining weather patterns. It typically consists of a sealed container that expands and contracts in response to changes in air pressure, which can then be read on a scale to indicate the current atmospheric pressure.
