About Sleep Log

⚠️ This feature is currently in beta
We are announcing this as a beta feature due to the following perspectives.

• Daytime sleep is not measured
• There are significant individual differences in sleep measurement accuracy
• If you do not regularly create Totonoi Logs through sauna device Data Sync, sleep data cannot be generated.

Taking a sauna properly relaxes your mind and body, naturally preparing you for an easy sleep.
As a result, sleep becomes deep and sound, and waking up becomes refreshed and light, it is said.

This page explains the items, practical uses, and instructions for the "Sleep Log".

1. What is a Sleep Log?

In Sanokuni, the sleep record created by syncing data from the sauna device is called a "Sleep Log".
You can link and review the sauna session you took just before with the subsequent Sleep Log.

1.1 Sleep Log Overview

1. Sleep Score
   The score is calculated based on the total sleep duration and the ideal ratio of deep sleep to light sleep.
2. Sleep Data Retrieval Date
   Displays the date the sleep was recorded.
3. Tag for Totonoi Log Available
   If there is a sleep record within 12 hours of taking a sauna, the immediately preceding Totonoi Log will be linked.

1.2 Sleep Log Details

1. Sleep Score
2. Sleep Data Retrieval Date and Sleep Duration

3. Sleep Composition Graph
   It breaks down sleep into three components and displays the ratio of each. Please refer to How to Read the Graph for details.

💡 Tips for effective use

Please use this as a hint to find the best sauna style that suits you, taking into account the effects of the sauna on your sleep.

• How does sleep differ between "days you went to the sauna" and "days you didn't"?
• How many Sets did you do on the day you slept deeply?
• Which sauna timing suited you better, evening or night?
• Does the quality of your sleep change depending on how you spend your time after the sauna?

2. How to Use the Sleep Log

2.1 Creating a Sleep Log

1. Sleep wearing the sauna device
   *To create a Sleep Log, at least 30 minutes of sleep data is required.
   *Sleep measurement is available from 20:00 to 10:00 the next morning.

   💡 Tips for successful measurement

   • If the sauna device is strapped too tightly or too loosely, it may not measure accurately.
   • If external light hits the sensor on the back of the sauna device, it will not measure correctly.

2. Open "Sanokuni" after waking up
3. (If sauna device is not connected) Connect to the sauna device within "Sanokuni"

→ Sleep data will sync automatically, and your "Sleep Log" will be displayed

⌚ Data Sync Timing
Sleep data is synced to the app at the following timings.

1. When the sauna device is connected
2. When opening the app while connected to the sauna device
3. When syncing sauna data

*It may take a few seconds for the sleep data to appear on the screen.
