The graph of the Last 7 times is mainly for two purposes:
Display changes of the last 7 times;
Offer comparisons of current data with the previous 7 data and the average of 7 times.
The brainwaves are divided into five kinds of rhythms based on their frequencies. They are α wave, β wave, θ wave, δ wave, and γ wave.
Heart Rate (HR), also known as pulse, is the number of times a person's heartbeats per minute.
What is Pressure? There is a significant correlation between pressure and heart rate variability.  Pressure affects physical health, and continuing exposure to high stress may increase the risk...
What is Relaxation? When you are calm and relaxed, brain waves have unique characteristics, as studies have shown a link between increased alpha wave energy and relaxation.  The...
What is Heart Rate Variability (HRV) ? Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in...
Our brainwave changes according to what we are doing. When you focus your mind, studies have shown that the high-frequency energy of brain waves increases, and the low-frequency energy decreases.
Know about what is breath coherence.
