Oura Ring Heart Rate Analysis Using R

This page presents an analysis of my Oura Ring heart rate data collected between July 30, 2024 and September 30, 2024, analyzed using R.

Summary Statistics

Over the 63-day period analyzed:

• Average Resting HR: 52.8 bpm
• Range: 47.6 - 68.3 bpm
• Standard Deviation: 3.11 bpm
• Days with HR ≤50 bpm: 5 days
• Days with HR ≤52 bpm: 28 days
• Days with HR ≤55 bpm: 55 days

Time Series Analysis

Daily average resting heart rate over the two-month period, with threshold lines at 50 bpm (red) and 55 bpm (orange).

---

Distribution of Heart Rate Values

Histogram showing the distribution of daily average resting heart rate values. The red dashed line indicates the mean HR.

---

Cumulative Days Below Thresholds

This chart tracks how many days fell below various heart rate thresholds over time.

---

Weekly Trends

Weekly average resting heart rate with the shaded area showing the min/max range for each week.

Heart Rate by Category

Daily heart rate values color-coded by category:

• Very Low (≤50): Green
• Low (50-52): Light green
• Moderate (52-55): Orange
• Elevated (>55): Red

Before vs After Comparison

Comparison of heart rate trends before and after August 26, 2024.

Statistical Comparison:

• Before Aug 26: Mean = 53.4 bpm, SD = 4.16
• After Aug 26: Mean = 52.4 bpm, SD = 1.97

The data shows more stability in the “after” period with lower variability.

---

Trend Analysis

Linear regression analysis showing the overall trend in resting heart rate over time. The regression shows no significant trend (p = 0.788), indicating stable heart rate throughout the period.

---

Methodology

This analysis was performed using R with the following packages:

• tidyverse for data manipulation and visualization
• lubridate for date handling
• ggplot2 for creating visualizations

Data was exported from the Oura Ring app and processed to generate daily, weekly, and cumulative statistics.
