Sleep Data Tracking: 10-Week Follow-Up

Sleep Data Tracking: 10-Week Follow-Up Back in January, I kicked off an experiment to track my sleep with my Apple Watch Series 10, hoping to improve my rest and boost my deep sleep - the stage that is supposed to leave you feeling rejuvenated. My first night’s data (6 hours 52 minutes, 24.76% REM, 64.32% core, 8.74% deep, 2.18% awake) set the baseline, and I planned to check my progress after three months. Battery issues cut my tracking short at 10 weeks, but the data still revealed patterns I never would’ve noticed otherwise. Here’s what I learned about my sleep quality, how illness threw a curveball, and what the Apple Watch experience taught me. ...

Sleep Data Tracking

Sleep Data Tracking Analysing My First Night of Sleep with Apple Watch I recently decided to track my sleep using my Apple Watch (Series 10) because I thought it would be interesting. I plan to compare this data to my average sleep health in 3 months to see any progress. Here’s a breakdown of my sleep stages and a comparison to optimal sleep ratios. My Sleep Data: Time Slept: 01:09 AM - 08:01 AM Total Sleep Time: 6 hours 52 minutes Breakdown: REM Sleep: 1 hour 42 minutes (24.76%) Core Sleep (Light Sleep): 4 hours 25 minutes (64.32%) Deep Sleep: 36 minutes (8.74%) Awake: 9 minutes (2.18%) Optimal Sleep Ratios: REM Sleep: 20-25% Core Sleep (Light Sleep): 50-60% Deep Sleep: 15-20% Awake: Less than 10% Observations: REM Sleep: My REM sleep ratio is within the optimal range. REM sleep is when dreaming happens, and it’s important for memory and learning, so that’s a plus. Core Sleep (Light Sleep): My core sleep ratio is a bit on the high side. Light sleep is necessary for body maintenance, but having too much might mean I’m missing out on deeper, more restorative sleep. Deep Sleep: My deep sleep ratio is below the optimal range. Deep sleep is the most restorative phase, crucial for physical restoration. I’d like to get more of this to feel more refreshed. Awake: My awake time is minimal and well within the optimal range, so it seems like my sleep was quite undisturbed, which is good. While last night’s sleep didn’t feel amazing, I think taking averages over the course of three months will give a more accurate picture of my sleep health. Plus, I’ve already started actively making some changes, like actively avoiding YouTube on my phone before bed. Keeping consistent and tracking my sleep will hopefully show some progress and help me get better rest over time. It’s going to be interesting to see the results in a few months’ time. ...
