Ultrahuman Ring AIR

A great night’s sleep rejuvenates the body, boosts brain function, powers the immune system, and regulates hormones, forming the foundation for well-being and longevity.

Sleep deprivation, on the other hand, impairs us. Being awake for 18 or 24 hours is like having a blood alcohol content of 0.05% or 0.1%. If you only do one thing for your health: sleep better.

The Key to Better Sleep? Tracking It.

You can only improve what you measure. Sleep data helps you identify trends, pinpoint disruptions, and refine your habits to optimize rest.

Several tools exist for tracking sleep:

• Smartwatch
• Band
• Ring
• Sleep Journal

But not all devices are created equal. Smartwatches and bands often require daily charging, making overnight tracking inconvenient. The best option? A smart ring.
