Daily Health Metrics — São Paulo (Brazil)

Personal physiological time-series dataset of a single individual living in São Paulo, Brazil (America/Sao_Paulo, UTC−3). It is collected daily from a smart band (heart rate, SpO₂, steps, sleep stage, skin temperature) and a home blood-pressure monitor, and is used for long-term personal health trend analysis and anomaly detection.

⚠️ Purpose & privacy: This dataset is intended exclusively for personal medical-health data analysis (self-monitoring, trend review, anomaly screening). It contains sensitive physiological information for one individual. Do not distribute, republish, or use it for any purpose other than personal analytics without explicit consent.

Data source

• Smart band / wearable — continuous heart rate (bpm), blood-oxygen saturation (SpO₂ %), step count, sleep-stage classification, and body-surface temperature (°C).
• Home blood-pressure monitor — systolic/diastolic blood pressure (mmHg), recorded at scheduled daily checks (morning, midday, evening, before bed).
• Files are exported from the device companion app and archived locally as one CSV per day.

Repository layout

Daily uploads are organised by date so the history stays clean and version-controllable:

data/
└── 2026-08-13/
    └── health_metrics_20260813.csv   # ~5000 records

Update frequency

• Daily. A new CSV is appended/uploaded every day under data/YYYY-MM-DD/health_metrics_YYYYMMDD.csv.
• Data volume: 1000–10,000 records per day (this snapshot: 5000).

Field description

Column	Type	Unit	Meaning
timestamp	string	ISO-8601	Local timestamp YYYY-MM-DDTHH:MM:SS-0300 (America/Sao_Paulo)
heart_rate_bpm	float	bpm	Instantaneous heart rate from the wearable
spo2_percent	float	%	Blood-oxygen saturation
steps	int	steps	Steps accumulated in the interval
systolic_bp_mmhg	float	mmHg	Systolic blood pressure (empty when not measured)
diastolic_bp_mmhg	float	mmHg	Diastolic blood pressure (empty when not measured)
sleep_stage	string	—	awake, light, deep, rem
body_temp_c	float	°C	Body-surface (skin) temperature

Blood-pressure columns are only populated at the few scheduled cuff measurements during the day; other rows are left blank.

Snapshot summary (2026-08-13)

• Records: 5000 (≈1 sample every 17 s across 24 h)
• Heart rate: 45 – 190 bpm (resting to exercise), mean ≈ 66 bpm
• SpO₂: 93 – 100 %, mean ≈ 97.5 %
• Steps: ~45,000 total (morning run + evening workout + daily walks)
• Sleep stages: awake 3333 / light 816 / rem 430 / deep 421
• Body-surface temperature: ≈ 33.1 – 35.5 °C (circadian rhythm)
• Blood pressure: 4 readings, e.g. 118/76 (07:10), 114/73 (12:30), 121/78 (18:30), 116/74 (21:45)

Typical use cases

• Long-term trend analysis of resting heart rate, sleep quality, and activity.
• Anomaly detection (e.g., SpO₂ dips, HR outliers, BP deviations).
• Correlation between daily activity, sleep stages, and next-day metrics.
• Personal health dashboards and periodicity analysis (weekly/monthly).
