Blood pressure
Blood pressure (BP) is the pressure of circulating blood on the walls of blood vessels.

Choking game
The choking game (also known as the fainting game and a wide variety of slang terms) refers to intentionally cutting off oxygen to the brain with the goal of inducing temporary loss of consciousness and euphoria.

Eigengrau
Eigengrau (German: "intrinsic gray", "own gray"), also called Eigenlicht (Dutch and German: "own light"), dark light, or brain gray, is the uniform dark gray background that many people report seeing in the absence of light.

Fatigue
Fatigue is a subjective feeling of tiredness that has a gradual onset.

Freediving blackout
Freediving blackout, breath-hold blackout or apnea blackout is a class of hypoxic blackout, a loss of consciousness caused by cerebral hypoxia towards the end of a breath-hold (freedive or dynamic apnea) dive, when the swimmer does not necessarily experience an urgent need to breathe and has no other obvious medical condition that might have caused it.

G-force
The gravitational force, or more commonly, g-force, is a measurement of the type of acceleration that causes a perception of weight.
New!!: Greyout and G-force · See more »
G-LOC
G-force induced loss of consciousness (abbreviated as G-LOC, pronounced 'JEE-lock') is a term generally used in aerospace physiology to describe a loss of consciousness occurring from excessive and sustained g-forces draining blood away from the brain causing cerebral hypoxia.

G-suit
A g-suit, or the more accurately named anti-g suit, is a flight suit worn by aviators and astronauts who are subject to high levels of acceleration force (g).

Hangover
A hangover is the experience of various unpleasant physiological and psychological effects following the consumption of alcohol, such as wine, beer and distilled spirits.

Hyperventilation
Hyperventilation (a.k.a. overbreathing) occurs when the rate or tidal volume of breathing eliminates more carbon dioxide than the body can produce.
New!!: Greyout and Hyperventilation · See more »
Hypocapnia
Hypocapnia or hypocapnea (from the Greek words υπό meaning below normal and καπνός kapnós meaning smoke), also known as hypocarbia, sometimes incorrectly called acapnia, is a state of reduced carbon dioxide in the blood.

Hypotension
Hypotension is low blood pressure, especially in the arteries of the systemic circulation.
New!!: Greyout and Hypotension · See more »
Hypovolemia
Hypovolemia is a state of decreased blood volume; more specifically, decrease in volume of blood plasma.
New!!: Greyout and Hypovolemia · See more »
Hypoxia (medical)
Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level.
New!!: Greyout and Hypoxia (medical) · See more »
Orthostatic hypotension
Orthostatic hypotension, also known as postural hypotension, occurs when a person's blood pressure falls when suddenly standing up from a lying or sitting position.
New!!: Greyout and Orthostatic hypotension · See more »
Panic attack
Panic attacks are sudden periods of intense fear that may include palpitations, sweating, shaking, shortness of breath, numbness, or a feeling that something bad is going to happen.
New!!: Greyout and Panic attack · See more »
Phosphene
A phosphene is a phenomenon characterized by the experience of seeing light without light actually entering the eye.
New!!: Greyout and Phosphene · See more »
Presyncope
Presyncope is a state of lightheadedness, muscular weakness, blurred vision, and feeling faint (as opposed to a syncope, which is actually fainting).
New!!: Greyout and Presyncope · See more »
Redout
A redout occurs when the body experiences a negative g-force sufficient to cause a blood flow from the lower parts of the body to the head.
New!!: Greyout and Redout · See more »
Retina
The retina is the innermost, light-sensitive "coat", or layer, of shell tissue of the eye of most vertebrates and some molluscs.

Roller coaster
A roller coaster is a type of amusement ride that employs a form of elevated railroad track designed with tight turns, steep slopes, and sometimes inversions.
New!!: Greyout and Roller coaster · See more »
Roller coaster elements
Roller coaster elements are the individual parts of roller coaster design and operation, such as a track, hill, loop, or turn.

Shock (circulatory)
Shock is the state of low blood perfusion to tissues resulting in cellular injury and inadequate tissue function.
New!!: Greyout and Shock (circulatory) · See more »
Stroke
A stroke is a medical condition in which poor blood flow to the brain results in cell death.
New!!: Greyout and Stroke · See more »
Syncope (medicine)
Syncope, also known as fainting, is a loss of consciousness and muscle strength characterized by a fast onset, short duration, and spontaneous recovery.
New!!: Greyout and Syncope (medicine) · See more »
Tunnel vision
Tunnel vision (also known as "Kalnienk vision") is the loss of peripheral vision with retention of central vision, resulting in a constricted circular tunnel-like field of vision.
New!!: Greyout and Tunnel vision · See more »
Vertical loop
The generic roller coaster vertical loop, where a section of track causes the riders to complete a 360 degree turn, is the most basic of roller coaster inversions.
