[Contents] ・Pillow body only Three reasons why the "Brain Sleep Pillow Neck Conditioning" is chosen: *① Unique structure to cool the brain for deeper sleep: Sleep quality is deeply related to brain temperature. The unique "ultra-breathable material" efficiently lowers the core body temperature of the brain while you sleep, leading to deeper non-REM sleep. You'll feel as if your head is being cooled down, and you'll wake up feeling refreshed. *② Fits the curve of the neck and reduces stress: The ergonomic, special form perfectly fits your neck's S-curve whether you sleep on your back or side. It minimizes the stress on your neck and maintains an ideal sleeping posture. It gently releases the stiffness in your neck caused by long hours of desk work or smartphone use while you sleep. * ③ Improved daytime performance with the feeling of "brain sleep": Deep sleep not only recovers brain fatigue but also improves concentration, judgment, and memory during the day. By getting high-quality sleep with the "Brain Sleep Pillow Neck Conditioning," you'll be able to enjoy both work and private life more actively.
