Can I wear my Circular Ring in a Sauna?

We do not recommend wearing your Circular Ring 2 in a sauna.

While the ring is designed to handle a wide range of conditions, its maximum working temperature is 60°C (140°F). Most saunas operate at temperatures that exceed this limit, often ranging between 70°C and 100°C (158°F–212°F), which could:

Damage the internal sensors or battery

Affect the ring's long-term durability

Lead to inaccurate biometric readings (especially for features like ECG, which is rated for 0–35°C)

To protect your device and ensure safe, accurate use, it's best to remove your Circular Ring before entering a sauna, steam room or hot tub.

For information:

• Operating Temperature: -10°C; 45°C / 14°F; 113°F
• Charging Temperature: 0°C; 45°C / 3°F2; 113°F
• ECG working temperature: 0°C; 35°C / 32°F; 95°F
• Humidity: up to 93%, noncondensing
• Atmospheric Pressure: 50kPa; 106 kPa
