Synbul Sleeping Guard: A clinically proven solution for better quality sleep


Our device has undergone rigorous clinical trials, demonstrating its ability to improve sleep quality and alleviate symptoms of sleep apnea and snoring.

Individual patients have experienced real-world benefits with Synbul, reporting improved sleep, increased energy levels, and enhanced overall well-being.

  • Poor Quality Sleep

    Studies have found a significant association between sleep apnoea and reduced physical performance, a weakened immune system, and an increased risk of heart disease by up to 50%. Imagine feeling stronger, healthier, and less susceptible to illness that's the power of good sleep.

  • Compromised Mental Health

    Research shows a strong connection between poor sleep and increased stress, impaired memory and cognitive function (as much as losing 2 nights of sleep!), and even an increased risk of depression. Picture yourself feeling sharper, focused, and more in control of your day – that's what Synbul can help you achieve.

  • Snoring

    Studies reveal a correlation between snoring and decreased daytime alertness, difficulty concentrating (studies show a 20% decrease in reaction time), and a higher risk of accidents. Additionally, snoring can disrupt sleep for your partner, impacting their overall well-being as well. Imagine waking up feeling refreshed and energized, ready to tackle the day, and knowing you're not disrupting your partner's sleep – that's the peace of mind Synbul offers.
