If the same force is applied to two areas, a smaller and a larger one, the pressure would be greater for the smaller area.

You will probably agree that it is less scary to be stepped on by someone wearing running shoes than by someone wearing stilettos. For example, if you try pushing a sharp knife down through a carrot or a tomato, you will cut it. The area where the force is applied is small, so the pressure is high enough to cut through the object. If, on the other hand, you use a blunt knife, you will not be able to cut through because the area is greater and the pressure is lower as a result.

In some cases, pressure of gases is measured as the difference between the total or absolute pressure and the atmospheric pressure. This is known as gauge pressure, and it is the pressure measured when determining the air pressure in car tires. Measuring devices often show gauge pressure, although absolute pressure sensors are also in use. Atmospheric or air pressure is the pressure of air in a given environment. It usually refers to the weight of the column of atmospheric air above the unit surface area.

Atmospheric pressure affects weather and temperature. Considerable changes in the atmospheric pressure cause discomfort for people and animals.

The decrease in atmospheric pressure can cause psychological and physical discomfort for people and animals, or even death. For this reason, airplane cabins, which would otherwise experience low air pressure at cruising heights, are artificially pressurized. Atmospheric pressure decreases with the increase in altitude.

People and animals, who live at high altitudes, for example in the Himalayas, adapt to the low pressure. Travelers, on the other hand, often need to take precautionary measures to avoid discomfort. Some people, such as mountaineers, are affected by altitude sickness, caused by oxygen deficiency in the blood. This condition can become chronic with prolonged exposure. It typically happens at altitudes above 2, meters.

In severe cases, people may be affected by high altitude cerebral or pulmonary edema. To prevent altitude-related health problems, medical professionals recommend avoiding depressants such as alcohol and sleeping pills, and also to hydrate well, and ascending to higher altitudes at a slow pace, for example on foot, instead of using transportation.

Additional recommendations include a diet high in carbohydrates, and resting well, especially for individuals who ascended quickly. This will allow the body to combat the oxygen shortage, which results from low atmospheric pressure, by producing more red blood cells to carry oxygen, and by increasing heart and respiratory rates, among other adaptations. Emergency treatment for severe altitude sickness has to be provided immediately.

It is paramount to bring the patient to lower altitudes where the pressure is higher, preferably to an altitude below meters above sea level. Treatment also includes medication and the use of the Gamow Bag. It is a portable lightweight container that can be pressurized by using a foot pump. The patient is put inside this bag to simulate lower altitudes. This is an emergency treatment and the patient still needs to be transported to lower altitudes.

Low atmospheric pressure is also used by athletes, who sleep in simulated high-altitude environments but exercise in normal conditions. This helps their bodies to adapt to high altitudes and start producing greater amounts of red blood cells, which, in turn, increases the amount of oxygen carried through their body, and enhances their athletic abilities.

For this purpose athletes often use altitude tents or canopies, which have low atmospheric pressure inside. Astronauts and pilots who have to work at high altitudes use pressure suits to compensate for the low air pressure. Full-pressure suits are used in space, while partial-pressure suits, which provide counter-pressure and assist breathing at high altitudes are used by pilots. Hydrostatic pressure is the pressure of fluid caused by the force of gravity.

It is an important factor not only in engineering and physics, but also in medicine. For example, blood pressure is the hydrostatic pressure of blood on the blood vessel walls. It usually refers to arterial pressure and is represented by two numbers: systolic or maximum pressure and diastolic or minimum pressure during a heartbeat.

The instrument used to measure blood pressure is called a sphygmomanometer. Millimeters of mercury are used as units for blood pressure measurements, even in countries like the USA and the UK, where inches are used for measuring length.

A Pythagorean cup is an interesting device, which uses the principles of hydrostatic pressure. According to legend, it was designed by Pythagoras to moderate wine drinking. Other sources mention that this cup was meant to regulate the drinking of water during a drought. It usually has a stem and always has a dome inside of it, which allows liquid to enter from the bottom through an embedded pipe.

This pipe runs from the bottom of the stem of the cup to the top of the dome, then bends, and opens into the cup, as in the illustration. Liquid enters the pipe through this opening. The other side of the pipe that runs through the stem also has an opening at the bottom of the stem. The design and operating principles of a Pythagorean cup are similar to the ones in modern toilet bowls.
