Why your Smart Watch is not your friend when it comes to sleep
Smart watches are so popular at the moment; indeed, you may well have one on your Christmas list this year. Have you ever wondered about the impact of monitoring your sleep though?
Firstly, let’s talk about accuracy. Compared to Polysomnography tests which measure brain waves, heart rate, breathing, blood oxygen levels and body and eye movements during sleep through electrodes attached to the skin smart watches are not that accurate. They tend to be based just on movement or possibly also heart rate and therefore 𝑎𝑡 𝑏𝑒𝑠𝑡 its 70% accurate but can drop to around 35% accurate.
Secondly, let’s talk about the impact on your mood of monitoring your sleep in this way. Participants in a study were randomly given a “sleep score” despite all their sleep being exactly the same quality. Those give a low score showed lower mood, difficulties with daytime thinking and increased sleepiness. Those who got told they had a great night sleep showed exactly the opposite.
So, even if you watch was accurate the impact on your mood of monitoring your sleep in this way could change your emotional state and concentration.
