Important Stages of Sleep and Oxygen in the Blood


It is worth noting that scientists have identified two main phases of sleep: fast and slow.

A person must cycle through these stages in order to feel rested.

The sleeper enters the slow phase immediately after falling asleep, but with a flash of bright light or loud sounds, he will quickly wake up and this will negatively affect his physical condition in the morning.

In the phase of REM sleep, a person is mentally protected and in these moments a complete restoration of thought processes takes place.

Heart Rate Monitor: Which is the Best to Choose?


It is just worth waking up in the fast phase, then the person is full of strength and energy for the whole day. Modern gadgets are great at tracking sleep phases.

Another indicator that helps to get the most detailed information is the level of oxygen in the blood, which is monitored using an SpO2 sensor.

It may sound strange, but oxygen in the blood – or at least a drop in its level during sleep – is associated with a condition called apnea, or, more simply, short-term respiratory arrest for more than 10 seconds.

So, for example, according to the results of the studies of one of the US institutes, more than 22 million people suffer from this syndrome, but often they do not even know about it.

Therefore, the choice of an activity and sleep tracker should be approached responsibly.

Terminology explanation of Sleeping Tracking


Before choosing the best sleep tracker to monitor the body at this time, you need to know exactly what functions it should have.

The technology used in these gadgets is much more advanced than smartphone apps, which use an accelerometer to track movement and, as a result, the data is much more accurate.

The first models of fitness trackers used the movement of the wrist to track sleep, that is, only the accelerometer was involved in monitoring.

But now high-precision optical heart rate sensors have joined the motion sensors.

The pulse rate during sleep allows you to estimate not only the duration, but also the stage of sleep in which you were in a particular period of time.
