What is New Bed Syndrome?
You've finally arrived at your long-awaited vacation destination. Whether you're in paradise, listening to the waves gently crashing on the shore, or on a business trip aiming to impress your coworkers at a major conference, you find yourself in a luxury five-diamond hotel complete with spa treatments. You would expect relaxation and good sleep to come easily in such opulent surroundings. However, what do you do when, despite the comfortable and lavish accommodations, you still struggle to sleep well? It may seem puzzling, but researchers have recently identified a phenomenon known as "New Bed Syndrome" that may be to blame.
If you haven't been sleeping well on your new mattress and are looking to gain insight about this somewhat unfamiliar sleep issue, keep reading the expert info from local sleep specialists to learn more about the 'First-Night Effect' (FNE), and other sleep-related problems, such as New Bed Syndrome. The sleep specialists at Mattress World Northwest will also emphasize potential sleep solutions, like an adjustable bed, so that you can be on your way to achieving the best night’s sleep possible.
New Bed Syndrome Explained
Researchers have long been intrigued by what is informally known as the "New Bed Syndrome" or the ‘First-Night Effect’ (FNE). This phenomenon is characterized by difficulty in feeling rested and achieving adequate sleep quality when sleeping in a new environment or on a different sleep surface. Recent studies say that during New Bed Syndrome, or the First-Night Effect, the brain remains partially awake throughout the night. This partly alert state allows us to be more vigilant, as some parts of the brain stay active while others drift into light sleep. This subconscious behavior likely serves as a protective mechanism against potential dangers, which, in turn, lessens our overall sleep quality.
After discovering this phenomenon, many may wonder how long the 'First-Night Effect' (FNE), or New Bed Syndrome, can last. Additionally, you might be curious about the difference between FNE and New Bed Syndrome.
New Bed Syndrome v. the First-Night Effect
The main distinction between the two concepts is that the term 'First-Night Effect' (FNE) refers to sleep disruption or disturbance in a new or unfamiliar sleeping environment. For example, FNE can occur when you sleep in a hotel, go camping, or stay at a friend's or family member's home, where the atmosphere seems unfamiliar.
On the other hand, New Bed Syndrome is the informal, non-scientific term for the same phenomenon, particularly related to trying to sleep on a new mattress. Both represent the same or similar issues while attempting to get some 'shut-eye': poor sleep quality due to resting in unfamiliar surroundings. This subconscious discomfort from unfamiliarity compels the brain to stay in a state of elevated alertness, preventing our mind from fully turning off and sleeping deeply.
First-Night Effect (FNE)
- Definition: A formal term for a science-based, documented phenomenon where sleep quality is influenced negatively during the initial night(s) in a new environment.
- Symptoms: Trouble falling or staying asleep, poor sleep efficiency, and still feeling tired the next day.
- Reason: An evolutionary survival mechanism whereby one hemisphere of the brain remains more attentive to guard against potential danger in unfamiliar surroundings.
- Perspective: The First-Night Effect involves trouble sleeping in a new environment, such as a hospital or hotel room.
- Scientific Observations: FNE diagnoses are supported by sleep studies, such as polysomnography, which records brain waves, blood oxygen levels, heart rate, breathing rate, and eye and leg movements while asleep. Medical professionals use sleep studies like these to diagnose sleep disorders.
New Bed Syndrome (NBS)
- Definition: New Bed Syndrome is an informal, non-scientific name for the specific experience of sleeping poorly in a new bed, on a new mattress.
- Symptoms: Waking up frequently throughout the night, trouble falling asleep, and feeling groggy the next day.
- Reason: New Bed Syndrome is based upon the exact survival mechanism as the First-Night Effect. Instead of being triggered solely by new surroundings, New Bed Syndrome is activated by discomfort and unfamiliarity with a new mattress support system.
- Perspective: New Bed Syndrome is specifically associated with a new bed or mattress.
- Scientific Observations: New Bed Syndrome is an informal term for the scientifically proven 'First Night Effect,' as documented in polysomnographic sleep studies.

How Does New Bed Syndrome Affect The Brain?
If you’ve been researching sleep issues and trying to figure out the cause of yours, it's no wonder you've encountered the concept of "New Bed Syndrome" (NBS). You have likely experienced symptoms of NBS without realizing it. This phenomenon most often happens when you’re away from home, but it can also occur when you struggle with insomnia or happen to be trying out a new mattress for the first time. In these scenarios, you may notice feelings of restlessness and fatigue, and in fact, the New Bed Syndrome, or the First-Night Effect, could be to blame.
If you regularly travel for work, you may often encounter a common sleep issue: difficulty falling asleep or staying asleep on a new mattress or in a different environment. You might not be aware of the neurological factors that contribute to the ‘First-Night Effect.’
Now, are you curious about how New Bed Syndrome may affect your brain? Consider the following information from local sleep specialists regarding New Bed Syndrome and the First-Night Effect.
Our brains have two hemispheres, the left and the right. Without delving into the complex science of brain biology, our sleep experts will highlight a few apparent distinctions between the left and right sides.
- The Right "Creative Side" - Much science-backed research suggests that the right hemisphere of the brain is responsible for creative or artistic functions. The 'right brain' daydreams and admires creative paintings or architecture. This side of the brain is said to play a role in guiding our imagination, playing upon feelings and emotions. The right hemisphere of the brain encourages abstract thought and non-verbal interpretation.
- The Left "Analytical Side" – Facts, arithmetic, calculated risk, and solution-finding are more typical patterns associated with the left brain. This side is accountable for logical thought processes. The left brain has the dominant ability to find solutions, remaining rational and reasoning with situations impassively. Many mathematical thinkers depend on the left side of the brain for these important functions.
- No Complete Separation – Both the left and right sides of your brain work together; they don't function separately, leaving a connective overlap between the left and right hemispheres. While some refer to one person as 'left-brained,' and another as 'right-brained' to describe their character traits, the truth is that we all utilize both sides of our brains every day.
So, is there a correlation between the left and the right sides of the brain with the First-Night Effect (FNE) or New Bed Syndrome (NBS)? Studies suggest that people who experience FNE or NBS appear to have dominantly active left hemispheres, while the right hemispheres remain asleep for the most part. In the scenario where FNE or NBS correlates with one side of the brain or the other, it seems the logical brain, the left side, often remains vigilant, even as the rest of the mind and body relaxes to settle into a new bed and mattress.

The ‘Dolphin Effect’
Recent findings suggest we have more in common with aquatic mammals than previously thought. Dolphins, known for their intelligence and their ability to communicate in ways similar to humans, may also possess brain structures that make their sleep patterns more comparable to ours than we realized before.
‘The Dolphin Effect’ is another term for the First-Night Effect (FNE). It may seem a bit strange to compare FNE with the way dolphins sleep. Nevertheless, dolphins can sleep while a portion of their brain is actually still awake. This ability is similar to what occurs during FNE and New Bed Syndrome. Still, humans depend on subconscious brain processes, also referred to as the involuntary nervous system.
On the other hand, dolphins don't have the same convenience. Rather, dolphins must keep part of their brain active while they're asleep to make sure they continue breathing. The 'Dolphin Effect,' scientifically known as unihemispheric sleep, is comparable to the First-Night Effect and New Bed Syndrome.
Overcoming New Bed Syndrome: Tips for a Restful Transition
Suppose you’ve found yourself struggling to sleep on your new mattress that you hoped would be a lot more soothing, cozy and comfortable. In this scenario, there are a few ways that you can reduce the odds of experiencing New Bed Syndrome, the First-Night Effect, and other sleep disruptions that sometimes go hand in hand with sleeping on a new mattress.
First off, if you've decided to get a new one, make sure you pick a high-quality mattress that fits your body. You want a mattress that provides ample support, pressure relief, and the ideal support and comfort your body deserves to achieve deep, rejuvenating sleep.
For a more seamless change to a new mattress, keep these tips for a restful transition in mind:
- Change the Mattress, But Keep the Sheets: When getting a new mattress, many people choose to buy new sheets as well. While a fresh set of sheets can enhance your sleep experience, this 'newness' may contribute to what is known as New Bed Syndrome. Using your old sheets with a new mattress can be beneficial because it helps minimize unfamiliar surface textures, making it easier to fall asleep.
- Use Your Old Pillow or Blanket – If you get a new mattress or are traveling for work or play, it can be helpful to bring an item you're familiar with or keep an item that's familiar to you on the bed. If you haven't opted for a new pillow with your new mattress, using your existing pillow is a realistic choice. Keeping a few items you know you like on the bed can help create familiarity in a new sleep environment.
-
Time is of the Essence – We humans are admirably adaptable, so don’t let your trouble with sleep get in your head. For most people, time is of the essence, and in most scenarios, allowing your body a little time to adjust is all you’ll need to sleep through the night. Regardless of New Bed Syndrome or the First-Night Effect, you should anticipate an adjustment period—up to 30 to 90 nights— as your body adjusts to the comfort and support of a new mattress.
