The Evie Ring tracks sleep duration and sleep quality, including your sleep stages – light, deep, and REM. For a deeper analysis of your sleep stages as well as a look at your week, click the “>” and see how your sleep was over the course of the week. Also included are average figures from the previous evening of your Resting Heart Rate, Heart Rate Variability, SpO2 (Blood Oxygen), Skin Temperature Variation, and Respiration Rate. Finally, you can set a sleep goal on the “Today” page if you’re looking to achieve a certain amount of sleep each night.
A healthy sleep pattern involves not only the distribution of sleep stages but also the total duration of sleep. The National Sleep Foundation recommends the following sleep durations for different age groups:
Age Group Recommended Sleep Duration
Adults (18-64) 7-9 hours
Older Adults (65+) 7-8 hours
These are general guidelines, and individual sleep needs will vary. Some people may feel rested and refreshed with slightly less or more sleep than the recommended amount. However, consistently sleeping less than 7 hours per night can lead to sleep deprivation and negatively impact physical and mental health.
Here's a breakdown of a healthy sleep pattern incorporating both duration and stage distribution for an adult:
- Total Sleep Duration: 7-9 hours
- Awake: 4-5% of total sleep time
- Light Sleep: 45-55% of total sleep time
- Deep Sleep: 13-23% of total sleep time
- REM (Dreaming): 20-25% of total sleep time
This distribution can vary depending on age, individual differences, and sleep needs. It's important to note that not everyone experiences the same exact distribution, but the general pattern remains consistent.
To promote a healthy sleep cycle, it's essential to prioritize good sleep hygiene practices, such as maintaining a consistent sleep schedule, creating a relaxing bedtime routine, and avoiding stimulants before sleep.
It's important to prioritize getting enough quality sleep and maintaining a consistent sleep schedule to support overall health and well-being. If you have concerns about your sleep patterns or experience persistent sleep problems, consult a healthcare professional for personalized guidance and treatment.
