Collection: Infrared Sleep Socks | Merino Wool | Clinically Proven Sleep Support

Fall Asleep Faster. Sleep Deeper. Wake Up Restored.

Accapi Infrared Sleep Socks combine 72% merino wool with proprietary infrared-emitting fiber technology — creating a clinically studied solution for better sleep that works with your body's natural thermoregulation to help you fall asleep faster, sleep more deeply, and wake feeling more rested.

Clinically Studied — Published in the Journal of Sports Medicine and Physical Fitness (2025)
A peer-reviewed clinical study on Accapi infrared sleep socks found significant improvements in sleep quality after just two weeks of nightly use:

• Insomnia severity scores reduced significantly
• Slow-wave sleep — the most restorative sleep stage — increased significantly
• 60% of participants reported no insomnia after two weeks (vs 26.6% before)
• More than 8 out of 10 participants would recommend the socks for improving sleep

How It Works — The Science of Foot Warmth & Sleep
Restful sleep depends on effective body temperature regulation. As your feet warm up, a signal is sent to the brain triggering vasodilation — the process by which your body dissipates heat and promotes melatonin production, the hormone that governs the sleep-wake cycle. Accapi's infrared fiber enhances this process by maintaining foot warmth throughout the night, helping to sustain the conditions for deeper, less fragmented sleep.

Merino Wool + Infrared Fiber — A Powerful Combination
Merino wool is naturally hygroscopic — managing moisture and regulating temperature throughout the night. Combined with Accapi's infrared-emitting fiber, which enhances peripheral circulation and thermoregulation, the result is a sock that keeps your feet at the optimal temperature from the moment you put them on until you wake up.

No compression. No medication. Just better sleep — naturally.
