Sleep

One of the most important functions of a human being

Sleep isn't just a passive state—it's a critical biological process. During sleep, your body:

  • Repairs tissues and strengthens your immune system
  • Consolidates memories and processes information
  • Regulates hormones crucial for growth and metabolism

At Nuku, we're passionate about helping you unlock the power of restorative sleep through better breathing. Let's dive into the science behind sleep and how our products can make a difference.

almost 40%

Almost 40% of adults fall asleep accidentally during the day at least once a month.

7.5X

Adults aged 27 and above who sleep less than 6 hours in a day are 7.5 times more likely to have a higher body mass index. 

The Foundations of Health

Sleep is the cornerstone of our physical and mental health. During sleep, our bodies:

  • Repair and regenerate tissues
  • Consolidate memories and process information
  • Regulate hormones crucial for growth and metabolism
  • Strengthen our immune system

 

Chronic sleep deprivation can lead to:

  • Increased risk of cardiovascular diseases
  • Weakened immune function
  • Impaired cognitive performance and decision-making
  • Higher susceptibility to mood disorders like anxiety and depression

Did you know?

About 30% of adults have symptoms of insomnia, with 10% having insomnia that impacts their daily activities.

 

Studies show that consistent, quality sleep can:

  • Reduce your risk of heart disease by 30% (Harvard Medical School, 2019)
  • Improve cognitive performance by up to 50% (National Sleep Foundation, 2020)
  • Lower the risk of obesity by 55% (American Journal of Clinical Nutrition, 2018)

But here's the kicker: 1 in 3 adults don't get enough sleep (CDC, 2020). Are you one of them?

The Science of Breathing

Now, let's talk about breathing. 

 

We do it about 20,000 times a day, often without a second thought.

 

But how you breathe matters—a lot.

 

Nasal breathing is nature's intended way. When you breathe through your nose:

  • Air is filtered, warmed, and humidified before reaching your lungs
  • Nitric oxide production increases, improving oxygen absorption by up to 18%
  • Your parasympathetic nervous system activates, promoting relaxation and better sleep

 

However, 61% of people habitually breathe through their mouth, especially during sleep (Journal of Oral Rehabilitation, 2019). 

 

This can lead to:

  • Increased risk of sleep apnea and snoring
  • Dry mouth and throat irritation
  • Lower oxygen saturation in the blood

 

Breathe Through Your Nose

Our Nuku Nasal Strips work by:

  • Gently widening the nasal passages
  • Reducing airflow resistance
  • Promoting easier, more efficient breathing through the nose

The Science Behind It:


Studies have shown that nasal dilators like our strips can significantly reduce snoring and improve sleep quality. A 2018 study published in the Journal of Clinical Sleep Medicine found that nasal dilators improved oxygen saturation and reduced snoring intensity.

Stop Mouth Breathing

Our mouth tape helps by:

  • Encouraging nasal breathing throughout the night
  • Reducing mouth breathing and its associated problems
  • Promoting more restful, uninterrupted sleep

The Research: 

 

A 2015 study in the journal "Sleep" demonstrated that mouth taping led to improved oxygen saturation and reduced snoring in participants with mild obstructive sleep apnea.

The Core

While our products can significantly improve your sleep, they work best as part of a comprehensive sleep hygiene routine. We recommend:

  • Maintaining a consistent sleep schedule
  • Creating a cool, dark, and quiet sleep environment
  • Limiting screen time before bed
  • Regular exercise (but not too close to bedtime)
  • Managing stress through relaxation techniques

 

At Nuku, we're committed to helping you achieve the restorative sleep you deserve. By understanding the science of sleep and leveraging the power of proper breathing, you can transform your nights and elevate your days. Ready to experience the science of better sleep?

Effect of Oral Breathing on Cognitive Activity Using Functional Brain Imaging

"Oral breathing directly affects behavioral performance and dental health. Various relationships between oral breathing and periodontal disease have been well-described. However, the effect of oral breathing on cognitive performance remains unclear. This study aimed to investigate the effects of oral breathing on cognitive function using functional magnetic resonance imaging (fMRI). "

The Impact of Mouth-Taping in Mouth-Breathers with Mild Obstructive Sleep Apnea

"A total of 20 patients with mild OSA were included. Following the taping of the mouth, a good response was found in 13 patients (65%). The median apnea/hypopnea index (AHI) decreased significantly, from 8.3 to 4.7 event/h (by 47%, p = 0.0002), especially in supine AHI (9.4 vs. 5.5 event/h, p = 0.0001)"

The Impact of Nasal Breathing During Exercise on Cerebral Blood Flow

"Achieving hypercapnic-induced vasodilation while exercising can increase cerebral blood flow (CBF) to a greater extent than during normoxic conditions. Evidence suggests that nasal breathing during a maximal aerobic effort can elicit a hypercapnic condition."

FAQs

Got questions? We’ve got answer...

What are Nuku Nasal Strips & Mouth Tapes, and how do they work?

Nuku Nasal Strips are comfortable, adhesive strips that you place across your nose to gently open up your nasal passages. By improving airflow through your nose, they help reduce snoring and nighttime congestion, allowing you to breathe better and sleep more soundly.

 

Nuku Mouth Tape is a specially designed, gentle adhesive tape that you apply over your lips before bedtime. It encourages you to breathe through your nose instead of your mouth during sleep, which can help reduce snoring, dry mouth, and other issues associated with mouth breathing.

Are Nuku Nasal Strips and Mouth Tapes safe to use?

Yes, both Nuku Nasal Strips and Mouth Tapes are made with safe, hypoallergenic materials and are designed for comfortable, overnight use. However, if you have sensitive skin, pre-existing nasal conditions, or underlying respiratory issues, we recommend consulting with your doctor before trying either product.

Can Nuku Nasal Strips and Mouth Tapes help with sleep apnea?

While Nuku Nasal Strips and Mouth Tapes may help alleviate some symptoms associated with mild sleep apnea, such as snoring and mouth breathing, they are not a substitute for medical treatment. If you suspect you have sleep apnea, please consult with your doctor to discuss the most appropriate course of action.

How often should I use Nuku Nasal Strips and Mouth Tapes?

You can use Nuku Nasal Strips and Mouth Tapes as often as needed to help improve your breathing and sleep quality. Many of our customers use one or both products every night as part of their bedtime routine. However, if you experience any discomfort or irritation, take a break and consult with your healthcare provider if symptoms persist.

Can I use Nuku Nasal Strips and Mouth Tapes together?

Yes of course, you can use Nuku Nasal Strips and Mouth Tapes together for a comprehensive approach to better breathing and sleep. Many of our customers find that using both products offers the most significant improvement in their sleep quality and overall well-being.

What if I'm not satisfied with my Nuku Nasal Strips or Mouth Tapes?

We're confident that you'll love the benefits of Nuku Nasal Strips and Mouth Tapes. However, if for any reason you're not completely satisfied with either product, we offer a 30-day money-back guarantee.
