Difference Between Blackout and Whiteout

Getting unconscious is very common when a person is not aware of himself and the actions happening in the surrounding.

When a person’s blood pressure decreases or becomes weak, he experiences brief unconsciousness (syncope and fainting).

Due to airborne maneuvers, passengers may get blurry vision when traveling by plane. Blackout and whiteout are two medical states when people become unconscious or suffer nausea due to certain conditions.

Blackout vs Whiteout

The main difference between blackout and whiteout is that blackout occurs due to a sudden fall in blood pressure. On the other hand, whiteout means when people feel nausea or lose their temporary vision while traveling in the airplane due to positive and negative gravitation. Whiteout can also occur due to taking rides in an amusement park.

Blackout vs Whiteout

Blackout is that state when people faint or feels weak. Blackouts can be caused by several factors, including low blood pressure, stress, dehydration, and heat.

Consumption of alcohol can also be one of the reasons. Moreover, sometimes people can lose their memory for a temporary period or pass out for a few hours.

Whiteout is also a state when people are not conscious.

Everything around them becomes blurry, and it becomes difficult to distinguish in the colors because of the unbalance in the blood flow due to certain conditions like taking

adventurous rides or flying in the airplane when the high gravitational force is there.

What is Blackout?

As the name implies, a blackout occurs when we view everything in front of us to be dark due to insufficient blood flow. Due to the decrease of blood flow towards the brain, people might experience syncope.

Blackout happens when people faint. Under this condition, they lose consciousness for a temporary period.

The reasons can be many. Sometimes people blackout just because they experienced a minor injury. This condition is a clear sign of weakness.

Dehydration due to the heat could be a tiny cause of the blackout. Another reason could be a sudden injury to the head due to blood loss.

People who eat poor diets (junk food, sugary drinks) or have stress due to major problems may develop blackouts.

Serious conditions behind blackouts are seizures (disturbance in the neurons in the brain). Muscles contract as a result of this, and patients go unconscious.

Blackouts can also be caused by anemia (low hemoglobin levels).

By eating a well-balanced diet (fiber and protein-rich food), you can avoid common ailments like weakness and poor nutrition behind blackouts. Taking proper rest and thinking positive are two simple methods of prevention.

Proper medical assistance can resolve the blackouts due to the seizures and anemia accompanied by the meals that help in blood formation.

What is Whiteout?

Whiteout is a state in which everything around you appears to be white. It is caused due to a momentary eyesight problem, and multiple factors can cause whiteout,

including weather conditions, travel, a lack of routine, adventure, and medical issues.

To begin with, when there is a lot of fog or snow, our vision is obscured, and we are unable to drive or visit other locations because of the possibility of accidents and other environmental mishaps.

Simple steps can be taken to avoid this form of whiteout (work and travel according to the weather forecast). When people travel by air that time also whiteout could occur.

Usually, when elder people see a dim light due to higher age, they can face a whiteout.

Furthermore, positive and negative gravitation occurs as a result of the flight’s airborne movement, which generates an unconscious state and can obscure vision. Even people can feel nausea that leads to whiteout.

Disturbance in our routine can exhaust our bodies and induce mental over-exertion, which can lead to whiteout.
When riders on high-speed rides move their bodies by 180 or 360 degrees,

the surrounding area can become fuzzy, causing whiteout.

Main Differences Between Blackout and Whiteout

  1. Blackout is a condition when everything seems to be black or dark due to dizziness. However, whiteout is a condition when everything seems to be hazy.
  2. Blackout never occurs due to weather conditions. On the other side, whiteout could occur due to foggy and snowy weather.
  3. Blackout can be due to strong drugs and alcohol. On the contrary, whiteout is due to negative and positive gravitation scenarios because of traveling by air or taking rides.
  4. Blackouts are more common in adults and children. Whiteout, on the other hand, is typically experienced by the elderly.
  5. Blackout can be cured with a healthy lifestyle. However, whiteouts can be avoided by traveling according to the weather forecast and leading stress-free life.
Difference Between Blackout and Whiteout


Blackout and whiteout are two conditions when humans are not in a conscious state. There are many major and common reasons behind this state.

Due to blackout, people feel dizzy due to a change in the blood flow towards the brain. This state can be due to weakness, injury, consumption of alcohol and drugs, strong medication.

In whiteout conditions, people can have blurred vision or temporary vision loss. It is caused by hazy weather, dim lighting effect, tiredness.

Both conditions can be avoided by eating a nutritious diet, seeking medical help, putting all anxieties aside, and maintaining a good attitude in life.
