Kusha Karvandi, PES, CES, is the founder of Muzzle Sleep and a performance coach dedicated to helping people breathe better and sleep deeper. With over 15 years of experience in exercise science, Kusha has worked at the intersection of fitness, recovery, and wellness, always focused on unlocking human potential.
His journey with mouth taping started on two fronts: personally, after years of battling mouth breathing and restless nights, and at home, when his wife was referred by their holistic dentist to a myofunctional therapist for their children’s oral and airway development. When his kids began taping at night, the results were astonishing—his son’s front teeth shifted from a 45° forward angle to completely upright in just five months, without braces or orthodontics.
Drawing on his background in performance science, Kusha set out to design the first mouth tape people actually want to wear—soft, breathable, gentle on skin and beards, and safe enough for kids. That became Muzzle Sleep, a patented, rigorously tested solution trusted by doctors, myofunctional therapists, and families nationwide.
Today, Muzzle helps thousands reduce snoring, improve recovery, and wake up energized. More than just a product, it represents Kusha’s mission: to create science-backed, minimalist solutions that make quality rest effortless—for adults striving to perform at their best, and for children growing into healthier, stronger versions of themselves.
