The Complete Health Tracking Guide: What to Track and Why
Health tracking is the practice of writing down a small number of measurements on a regular schedule, so that a change across weeks becomes visible instead of remembered. The post organises what to track by how fast each thing moves: water, medication and mood every day; exercise, weight and sleep every week; body measurements and blood pressure every month. For each it gives a reason, a frequency and a target. The targets are its own. Its most useful advice is at the end and it is about restraint — track one measurement for two weeks, and add a second only once the first has stopped needing thought.
Why Track Your Health?
Health tracking transforms vague goals into measurable progress. Without data, "getting healthier" is an aspiration. With data, it becomes a clear path with milestones and course corrections. People who write down what they actually do are markedly more likely to reach their goals than those who rely on memory and intuition alone.
Essential Metrics to Track
Daily Tracking
Water Intake
- Why: Dehydration affects energy, cognition, and physical performance
- How often: Every glass, throughout the day
- Target: 30-35 ml per kg of body weight
- Tool: LifeWell water tracker with reminders
Medication Adherence
- Why: Missing doses reduces treatment effectiveness
- How often: At each scheduled dose time
- Target: every scheduled dose, with a missed one recorded rather than scored
- Tool: LifeWell medication tracker with push notifications
Mood
- Why: Emotional patterns reveal health insights
- How often: 1-3 times daily
- Target: Awareness and trend identification
- Tool: LifeWell wellness journey mood tracking
Weekly Tracking
Exercise
- Why: Activity patterns predict cardiovascular and mental health
- How often: Log each session
- Target: 150 minutes moderate or 75 minutes vigorous activity per week
- Tool: LifeWell exercise tracker
Weight
- Why: Weight trends indicate nutrition and health status
- How often: Once per week, same conditions
- Target: Stability or gradual change toward goal
- Tool: LifeWell vitals tracker
Sleep Quality
- Why: Sleep affects every other health metric
- How often: Rate each morning
- Target: 7-9 hours with good quality ratings
- Tool: LifeWell wellness tracking
Monthly Tracking
Body Measurements
- Why: More meaningful than weight alone for body composition changes
- How often: Once per month
- Target: Trends in the desired direction
- Tool: LifeWell vitals tracker (waist, hip, chest measurements)
Blood Pressure
- Why: High blood pressure usually has no symptoms, so it is measured rather than felt
- How often: Monthly (or as directed by your doctor)
- Target: Below 120/80 mmHg
- Tool: LifeWell vitals tracker
How to Use Your Data
Look for Trends, Not Daily Numbers
A single day's data means little. Look at weekly and monthly trends to understand what is really happening.
Identify Correlations
Use your combined data to discover relationships:
- How does sleep quality affect next-day mood?
- Does exercise improve sleep?
- Does hydration affect energy levels?
- How do weekends differ from weekdays?
Share With Healthcare Providers
Bring your tracking data to medical appointments. Doctors appreciate objective data over vague descriptions like "I think I have been sleeping okay."
Adjust and Iterate
Tracking is not the goal. Improvement is the goal. Use data to identify what works and do more of it, and what does not work and change it.
Getting Started
If tracking feels overwhelming, start with just one metric for two weeks. Once that habit is established, add a second. Within two months, you will have a comprehensive health tracking system that operates on autopilot.
LifeWell is designed to make tracking as frictionless as possible. Quick-log features, smart reminders, and automated insights ensure that data collection enhances rather than complicates your health journey.

What people use it for
Starting with one thing rather than eleven
The daily check-in holds mood, energy, sleep, water, steps and weight on one screen. Two fields are enough. The post's own advice is one measurement for a fortnight before a second, and nothing in the app asks for more than you offer it.
Adjusting a goal so the page reports against your number
Every metric carries a goal you can change, and clearing yours falls back to the default rather than setting it to zero. Water starts at 2.2 litres and blood pressure at 120 over 80. Both are starting points rather than verdicts, and both are yours to move.
Reading a trend rather than a morning
Charts run across days, and a once-a-day reading is stored one row per day, so a correction overwrites rather than accumulating beside the mistake. The post's central instruction is to read weeks and months instead of a single day's number, which is the scale these charts are drawn at. Weeks, then months.
Taking the record to the appointment
`/health/export` produces everything as JSON, as a zip of CSV files, or as a PDF, and states per format what that format leaves out. The journal is never in the PDF, on the grounds that a PDF is a thing people print, hand over a desk and leave behind.
Knowing what is absent before you plan around it
There is no waist, hip or chest measurement, no body fat figure, no sleep quality rating and no weekly exercise target. There is no wearable, no pedometer reading and no automatic detection of anything either. Every entry in your record is there because you typed it.
Questions
What should I track first?
One thing, for two weeks. The post is explicit that tracking becomes overwhelming when it starts with everything, and suggests adding a second only once the first has stopped needing thought. In LifeWell the cheapest place to start is the daily check-in, where two fields are a complete entry and a skipped day costs you nothing at all.
How often should I weigh myself?
Once a week. The post asks for the same conditions each time — the same morning, the same point in the routine — because the conditions move the number as much as anything you did. It treats stability or a gradual change toward your goal as the reading that matters, and the trend across months as the only scale worth acting on. LifeWell stores one weight per day, so a correction replaces rather than adds.
How do I actually use the data?
Three things, in the post's order. Read weeks and months rather than any single day, because a day on its own means very little. Look for relationships between two things you already log — whether the hours you slept show up in the next day's mood, whether exercise shows up in your sleep, how weekends differ from weekdays. And take the record to an appointment, where a dated log is a better answer than a reconstruction.
What does LifeWell actually track as a number?
Twelve: water, steps, calories, weight, blood pressure as two separate readings, blood sugar, heart rate, cholesterol, sleep, mood and energy. Everything else it holds is a record of a different shape — a meal with a title and a portion, a symptom, a dose taken or missed, an exercise session with a duration and how hard it felt.
Does it track body measurements like waist and hip?
No. There is no waist, hip or chest measurement in LifeWell, and no body fat figure. The waist-to-hip ratio calculator at `/tools/waist-hip-ratio` works out a ratio from two measurements you type in and keeps neither of them, because it is a stateless tool. The personal record and the arithmetic are deliberately separate things.
What reminders does LifeWell send?
Three subjects. Water is not one. A medication, a calendar appointment, and a single nudge if you have not logged by nine in the evening, which arrives switched off. A medication reminder is a local notification scheduled on the device, plus a row written into the app's own inbox so that the reminder exists even if the notification never arrived. Push is reserved for what a server knows and a device cannot, so none of your reminders are sent that way.
Does the app tell me whether a reading is good?
No. It shows the reading, the goal you set, and the shape across days. It does not label a number, colour it, or offer any interpretation you did not ask for. Nothing here is a diagnosis, and a reading that concerns you belongs with a doctor who can see far more of the picture than a chart ever will.
Does anything measure itself — a weekly target, a watch, a fitness app?
None of the three. There is no weekly exercise target, and that refusal is written into the design rather than merely absent: the exercise page states that nobody here knows your health, your job or your joints well enough to set one, and there is no fitness score, training load or fitness age either. There is no wearable integration, no pedometer reading and no connection to another health app. Every entry exists because you put it there.
