@Nik Hi, from my experience, I suggest that the degree to which bluetooth can impact us varies according to our energy level, in some cases we may feel nothing, in others it can have a definite perceptible impact, the first common manifestations can be to feel a lesser degree of well being, enthusiasm, fun, and it can also contribute to a feeling of exhaustion and less relaxation at the same time, and in some cases pain
The best thing is to experiment with wifi/bluetooth on/off and see if we perceive any effects
