Can Humans Sleep Standing Up? Exploring The Possibility

Sleep is an essential part of human life, allowing our bodies and minds to rest and recharge but can humans sleep standing up?

While we are all familiar with the conventional image of slumber taking place on a soft, cozy bed, the question of whether humans can sleep standing up provokes the interest of many. 

The idea of a person dozing off upright is intriguing, almost laughable. In the animal kingdom, some species possess a unique anatomical mechanism enabling them to sleep securely while standing. 

What about human beings? Can Humans Sleep Standing Up?

Although it is technically possible for humans to sleep while standing up, it is an incredibly challenging task. To achieve this feat, one must be utterly exhausted. 

Additionally, it is not a sustainable sleeping position, as eventually, gravity will take its toll, and you will inevitably fall. Unlike certain animals, humans lack the specialized anatomical feature called the “passive stay apparatus” that locks our legs in place while at rest.

Soldiers Sleeping While Standing

This phenomenon has been observed in military personnel during extreme fatigue or extended periods of standing. It is a natural response of the body to try and find rest, even in an upright position.

Lack of sufficient sleep is a major reason behind it. Soldiers often have demanding schedules and may not have enough time to get proper rest, leading to fatigue which is why they may sleep even while standing. 

Military operations’ physical and mental demands can take a toll on their sleep patterns. The high-stress nature of their work can disrupt their sleep patterns and make it difficult for them to get quality rest. 

It can lead to exhaustion and the need to sleep at any given moment, even if they are in a standing position.

Environmental conditions also play a part in soldiers sleeping while standing. Soldiers often operate in extreme environments, such as in hot desert climates or cold mountainous regions. 

These conditions can make finding suitable resting spots or comfortable sleeping arrangements challenging, leading to soldiers sleeping while standing. Although, as explained earlier, it is an uncomfortable position for sleep.

Additionally, the weight of their gear combined with physical exertion can cause exhaustion, and a soldier, if standing, can find himself or herself asleep.

While sleeping while standing may seem unusual to those outside the military, it is a testament to soldiers’ physical and mental resilience. 

The demanding nature of their profession requires them to be able to function under challenging conditions, including sleep deprivation.

So We Can’t Sleep While Standing Up; What About Sleep Walking?

While it is true that the average person cannot maintain sleep while standing up due to the lack of a “passive stay apparatus” to support the body’s weight, sleepwalking presents an exception to this norm. 

Sleepwalking, also known as somnambulism, is a disorder characterized by performing complex actions while asleep, often in partial arousal.

During sleepwalking episodes, the brain transitions between different sleep stages, and the body temporarily disengages from its typical muscle paralysis during REM sleep. 

It allows sleepwalkers to physically move while still in a state of sleep. While the exact mechanisms behind sleepwalking remain elusive, it likely stems from an imbalance in the brain’s sleep-wake cycle.

Sleepwalking is more likely to occur during the first few hours of sleep when the individual is in a deeper slumber. While asleep, individuals are disconnected from their conscious awareness, yet their motor functions remain partially active. 

This unique state enables them to walk, talk, and even perform complex activities without full cognitive awareness. Somnambulism can be triggered by sleep deprivation, stress, and even genetic predisposition. 

While sleepwalking is generally considered harmless, it can occasionally lead to injuries or accidents. For instance, one could fall on the stair or walk into oncoming traffic while sleepwalking.

Despite our inability to naturally sleep while standing, sleepwalking reminds us of the complexities and mysteries surrounding our sleep cycle.

Animals That Can Sleep While Standing Up 

Several animals have the unique ability to sleep while standing up. Some of these animals include horses, bison, zebras, and elephants. These animals have evolved to have a special mechanism that allows them to rest upright. 

Cows also have the ability to do so. However, they mostly lie down when they sleep, providing them with more comfort and relaxation. 

Conversely, Giraffes can also sleep standing up, but only for short periods because of their long neck.

Why It’s Unhealthy To Sleep While Standing

It is important to ensure that we sleep in a position that promotes health and well-being. Sleeping while standing up is a practice that should be avoided, as it can harm our bodies and overall sleep quality. Here is why sleeping while standing is problematic.

1. It increases the risk of deep-vein thrombosis, a condition characterized by the formation of blood clots in deep veins, usually in the legs. When we sleep in an upright position, there is the pooling of blood in the lower limbs. 

This stagnant blood flow increases the risk of clot formation, which can travel to other body parts, potentially causing life-threatening complications such as pulmonary embolism. 

2. Sleeping while standing up applies unhealthy pressure on the vertebrae and joints. Our bodies are designed to rest and relax horizontally during sleep, allowing proper spine alignment and alleviating pressure on our joints. 

When you sleep while standing up, the strain on your vertebrae and joints leads to discomfort and long-term musculoskeletal complications.

3. Maintaining balance and stability while asleep in a standing position is challenging, especially during the REM stage of sleep when dreams occur. This increased risk of falling can result in fractures and concussions. 

4. Our muscles work continuously throughout the day to support our bodies in various activities. 

When we sleep in an upright position, these muscles must engage in a constant state of contraction to maintain balance. This prolonged muscle tension can lead to fatigue, muscle cramps, and stiffness upon waking up.

5. Disruption of sleep architecture refers to the different sleep stages throughout the night. Typically, our sleep cycles consist of alternating periods of non-rapid eye movement sleep and REM sleep. 

However, sleeping while standing up can prevent us from entering deep NREM sleep stages necessary for physical restoration and cognitive processing. 

This disruption can result in poor sleep quality, leading to daytime drowsiness, lack of focus, and impaired cognitive functioning.

How To Improve Your Sleep At Night

Getting a good night’s sleep is essential for your overall health. However, many struggle with falling asleep or staying asleep throughout the night. 

If you are tossing and turning, it may be time to make some changes to improve your sleep. 

Here are some simple strategies and techniques that can help you enhance the quality of your sleep and wake up feeling refreshed and rejuvenated.

  • Avoid consuming large meals, caffeine, and alcohol before bedtime, as they can interfere with the quality of your sleep and make it harder for you to fall asleep. 

Instead, opt for lighter meals and non-caffeinated beverages at least three hours before bed in the evening.

  • Consistency is key. Try to establish a regular sleep schedule by going to bed at the same time each night and waking up at the same time each morning, even on weekends. This helps regulate your body’s internal clock and promotes better sleep quality.
  • Physical activity during the day can also contribute to better sleep at night. Engaging in regular exercise can help tire your body out. 

And this will make it easier for you to fall asleep and stay asleep throughout the night. Simple and fun activities like walking, jogging, or even yoga can do the trick.

  • Avoid using your electronic gadgets while in bed, particularly mobile phones. The blue light emitted by these devices can disrupt your sleep patterns by suppressing the production of melatonin, a hormone that plays a crucial role in regulating sleep. 
  • Consider using melatonin supplements. Melatonin is a hormone naturally released in the brain about four hours before we feel sleepy. 

Taking melatonin supplements can help regulate your sleep-wake cycle and promote better sleep. However, consulting with a healthcare professional before using the supplements is important.


Can humans sleep standing up? While it may be possible for humans to briefly doze off while standing up, it is not a natural or sustainable way for humans to get rest. 

The human body is designed to sleep horizontally, allowing for proper blood circulation, muscle relaxation, and the release of growth hormones. Sleeping while standing up can increase the risk of falling and injury.

Therefore, it is safe to say that humans cannot sleep standing up for prolonged periods without experiencing significant discomfort and potential health risks.
