The Oura Ring is treated as useful for readiness metrics but not precise for sleep staging because it does not directly measure brain waves. Non-EEG wearables are described as useful but limited for distinguishing exact amounts of deep sleep and REM sleep. Pulsed electromagnetic field devices are presented as variable because some programs may help while others disrupt sleep. EMF shielding is discussed as a possible intervention but not a primary or universally effective one. The article cautions that devices influencing brain waves or electromagnetic signaling can disturb sleep if poorly matched to the individual.
