Sleep tracking:

1.  It is just simple, to measure whether you are having a sound sleep or not. Good sleep is important to keep our immune system healthy and mood balanced. Just imagine a fitness enthusiast not having a proper sleep and working it out in morning. They will never be able to give 100%  and in worst case might get themselves injured.
2. The Different measurement methods can be classified into two different areas. First where different stages of sleep are measured by mapping or measuring brainwaves, heart rate,  movements of eye, limb, chest and stomach, air flow from nose and mouth and blood oxygen level. second where only body movements are tracked.
3. Polysomnography ,Multiple Sleep Latency Test (MSLT) , Electroencephalography (ECG) are used in former case. Whereas Actigraphy and accelerometry  in latter.
4. Wearable devices like Fitness band and smart watch utilize Actigraphy where body movements are tracked to measure adequate or holistic data of our sleep time and efficiency.

Measuring heart rate:

1.  Terms aerobic and anaerobic respiration are profoundly used during workouts.
2. It is an excellent idea to measure your  heart rate so you can get the maximum benefit from your workouts. It is also beneficial to staying in shape, and keep the body out of the danger zone so you can exercise more safely as well.
3. There are several target zones a person typically falls into while exercising. The first zone is considered a healthy heart zone, but can also be easily classified as a warm-up or cool-down zone, or a comfortable zone for a beginner. In this range, a person will use 50 to 60 percent of their maximum heart rate.
4. In the next zone, a fat-burning or target heart rate zone, a person will use 60 to 70 percent of their maximum heart rate. Exercising in this zone is also very healthy for a beginner.
5. In the aerobic zone, a person will use 70 to 80 percent of their maximum heart rate. The aerobic zone is best used for endurance training, fat burning and general fitness, and is optimal for an advanced beginner or intermediate exerciser.
6. An anaerobic zone will use 80 to 90 percent of the maximum heart rate, and one should only exercise in this zone if they are in good health and have advanced knowledge of exercise.
7. With PPG or photoplethysmography, the wrist trackers or fitness bands measures body’s pulse. The process works by shining a light into the blood vessels located in your wrist after that they start to detect the changes in the blood volume which happens every time your heart beats and pushes blood throughout your body. Sensors on the device detect how much light your blood vessels reflect back thus less reflected light means a higher blood volume.

Distance Measurement and calories burnt:

1. Distance measurement or say number of steps, distance walked or covered during jogging or running.
2. As mentioned above acceleromertry is used to track movements and through customized algorithms, distance covered and calories burnt are calculated.

Blood Pressure monitoring:

1. Most fitness trackers take automatic oscillometric readings.
2. This automatic blood pressure readings consist of an electronic pressure sensor that is used to calculate the estimates of systolic and diastolic pressures
3. Where are some fitness bands with BP monitor uses a Photoplethysmogram (PPG), a heart rate sensor that makes use of the pulse oximeter to measure any changes in the light absorption.
