1. Tracking physical activity: not just steps

The main purpose of any fitness bracelet is to motivate you to move. Xiaomi Mi Band does this "excellently": it automatically recognizes walking, running, cycling, swimming (even in the pool!), as well as activities such as an elliptical trainer, rope or yoga, without having to manually start the workout, just put on the bracelet and start moving.

But there are nuances:

• 📊 The pedometer's accuracy depends on the correct position on the arm. If you wear the bracelet too loose, it can "lose" up to 15% of the steps. The optimal is to fasten the strap so that 1 finger passes between the body and the skin.
• 🏃 Recognition of sports works better in Mi Band 6 and newer models, for example, Mi Band 5 does not always distinguish running from fast walking, and Mi Band 8 even defines strength training by pulse and movement.
• 🏊 Waterproofness (5 ATM) allows you to swim with a bracelet, but in salt water or sauna it is better to remove - salt and steam reduce the battery life on the body. 20-30%.

For example, 30 minutes of running will give you more points. PAI», than 2 hours of slow walking.

2 Sleep monitoring: why it's more important than it seems

One of the most underrated features of the Mi Band is its sleep analysis, which not only shows how much sleep you've had, but also breaks down sleep into phases: deep, light, and light. REM (REM sleep, when we dream. Why is it important?

First, deep sleep is responsible for restoring your body, and if it is less than 15% of your total sleep time, you will wake up broken even if you slept for 8 hours. The Mi Band will show you this problem and tell you how to fix it (for example, go to bed earlier or reduce caffeine after 14:00).

Second, the bracelet tracks daytime naps (if you take 20 minutes naps) and nighttime wake-ups, which helps identify the causes of insomnia — for example, if you wake up every 3 a.m., it may be the noise from the street or low blood sugar.

⚠️ Note: If you sleep with a bracelet for less than 4 hours in a row, the data on the phases of sleep will be inaccurate.

3.Measuring pulse and oxygen in the blood: when it saves health

All models of the Mi Band, starting with the 5th version, are able to measure the pulse (HR) and oxygen saturation of the blood (SpO₂). But few people know how to use this data properly.

The pulse bracelet measures every time. 5-30 (configured in the Mi Fitness app) helps:

• 💓 Identify arrhythmia - if the pulse jumps from 60 to 100 beats without load, this is an occasion to consult a cardiologist.
• 🏋️ Control the intensity of your workouts, the optimal fat burning area — 60-70% maximum pulse rate (calculated as 220 — age).
• 😴 Track recovery from the disease, if the heart rate is above 80 after SARS, the body has not yet numbed.

SpO₂ (Oxygen in the blood - an indicator that drops sharply with COVID-19, asthma or sleep apnea. Normal — 95-100%. If the bracelet shows less 92% At night, it is a sign of night apnea (stop breathing) that increases the risk of stroke in the body. 3 once.

To improve the accuracy of measurement SpO₂, Drink a glass of water before bed and lie down on your back. Measure your score 10 minutes after you've gone to bed.

Important: Mi Band does not replace medical equipment, but can be the “first bell”: for example, a user from Moscow told how the bracelet helped detect tachycardia - the resting heart rate jumped to 120, although there were no symptoms, the doctor confirmed the diagnosis and prescribed treatment.

• 📱 Frequent notifications (especially if they are vibrational).
• 🌡️ Measurement SpO₂ At night (unplug if you don’t need to).
• 🔦 Screen lighting at maximum.
