Following overnight slow-wave enhancing auditory stimulation had a profound impact on cognitive processes, as measured by memory consolidation. Memory recall is not just a measure of one's ability to retrieve information, but a fundamental marker of brain health. It reflects the efficiency of neural networks and the brain's plasticity. Enhancements in memory recall highlight the potential of targeted auditory stimulation to strengthen these networks, thereby improving cognitive functions crucial for daily activities and overall mental well-being.

Enhancing slow-wave sleep through auditory stimulation led to a 37% reduction in blood cortisol levels during the first hour of sleep, alongside a 40% increase in aldosterone and a 38% increase in prolactin. These changes mark significant shifts in the body’s stress and recovery responses, directly influencing sleep quality and overall health. Reduced cortisol levels facilitate deeper, more restorative sleep, crucial for mental and physical well-being. Concurrent increases in aldosterone and prolactin further indicate a strengthened hormonal balance, enhancing the body's natural recovery processes during sleep. This direct impact on hormonal regulation highlights the effectiveness of auditory stimulation in optimizing sleep for improved well-being.
Acoustic stimulation of slow-wave sleep was shown to enhance heart rate variability, as evidenced by a 14.5% increase in SDNN during N3 sleep. This increase is indicative of improved autonomic control, particularly an enhancement in parasympathetic activity, which plays a crucial role in cardiovascular health. Higher heart rate variability, and specifically a higher SDNN, is associated with better cardiac function, lower stress levels, and a reduced risk of cardiovascular diseases. This finding highlights the broader significance of sleep quality on cardiovascular health, offering a promising, non-invasive method to support cardiac function and potentially reduce the risk of heart-related conditions through the enhancement of deep sleep stages.

How it works
Neurons and Their Function
Neurons are the building blocks of the brain, specialized cells that transmit information through electrical and chemical signals. These signals allow neurons to communicate, facilitating brain functions such as thinking, learning, and experiencing emotions.
Neuronal Firing in Sleep Cycles
During wakefulness, neuronal firing is fast and varied, supporting active thought and sensory processing. As we sleep, this activity slows and becomes more uniform, signalling the brain's shift to rest. Deep sleep features highly synchronized neuronal firing, distinct from the patterns of wakefulness and lighter sleep stages, demonstrating the brain's unique state of restoration.
Synchronized Activity During Deep Sleep
In deep sleep, neurons fire together in a synchronized manner, creating slow-wave patterns visible on an EEG. This synchronization supports critical functions like memory consolidation, hormone regulation, immune system strengthening, and mood and mental health stabilization, highlighting its essential role in comprehensive health and well-being.
Stimulating the Brain for Slow-Wave Enhancement
By introducing brief snips of sound, precisely timed to interact with the peak of a sleep slow-wave, our technology enhances the synchronization of neuronal firing. This targeted stimulation boosts the amplitude and duration of slow-wave activity, thereby increasing the effectiveness of this brain activity without necessitating more time asleep.
FAQs
The sound stimulation is only 50ms or 1/20th of a second. The timing of the sound is vital to elicit the brains response. However, the sound stimulation should only occur while you’re in your deepest phase of sleep, and the volume level is constantly being adjusted to be loud enough to elicit a response, but not so loud that it would interrupt your sleep. The sound itself is unimportant, but essentially sounds like a “click”.
During the night, the bluetooth connection in the headband is completely turned off. Everything needed to monitor and run the stimulation operates solely on the device. The headband does have a bluetooth connection to start a sleep session, and will require a connection to upload the data so you can review details about your sleep, but during the night, the headband is in stand-alone state, without any radio communication in use.
Our auditory stimulation technology has been the subject of extensive research for over a decade, focusing not only on its effectiveness but also on its safety. Each time researchers have investigated specific health safety concerns, the findings have consistently shown that not only is the stimulation safe, but it often yields positive health outcomes as well. For instance, in studies addressing potential impacts on respiratory function, results indicated that the stimulation led to a significant 14.5% improvement in Heart Rate Variability (HRV). This improvement is indicative of enhanced cardiovascular function. Such findings underscore our commitment to providing a product that is not just safe, but beneficial for overall health and well-being.
