Exposure to space causes rapid oxygen loss, pressure damage, and radiation injury.

Описание: Space is not just empty. It is a vacuum. There is no air, no pressure, and no protection. The human body is not built for this environment. If a person is suddenly exposed to space, the body begins to shut down almost immediately.

The Loss of Air

The first danger is the absence of oxygen. The air in the lungs is forced out, and no new oxygen can enter. Within seconds, the brain is starved of what it needs to function. A person would lose consciousness in about ten to fifteen seconds.

What Happens to the Body

Without pressure, gases inside the body expand. This does not cause the body to burst, but it does cause swelling. Moisture on the eyes, mouth, and skin begins to evaporate. Body fluids do not boil violently, but they do begin to vaporize in the vacuum, damaging tissues.

Temperature in Space

Space itself is cold, but heat does not leave the body instantly. A person would not freeze right away. Instead, the danger comes from oxygen loss and pressure changes long before temperature becomes a factor.

Radiation and Exposure

With no atmosphere to block it, radiation from the Sun and cosmic sources strikes the body directly. Cells are damaged at a deep level. Even brief exposure is extremely harmful.

What This Means

Without a protective suit, a human cannot survive in space. The body depends on air, pressure, and shielding that only Earth’s environment provides. Space offers none of these.

In Short

Exposure to space causes rapid oxygen loss, pressure damage, and radiation injury. Consciousness is lost in seconds, and survival is impossible without protection.
