And if you are not sleeping well you know about it and you invariably know why. For the overwhelming majority, this is expensive and uneccessary. Health services throughout the world are being clogged up with people who present themselves for no genuine reason and this is impacting negatively on the genuinely sick. You do NOT need hardware to tell you your room is too hot, too cold, too noisy, too light, too humid, because commonsense tells you this and has been doing so for hundreds of years. Arguably, the focus on health is going too far.
These assertions are, on their face, among the most farcical and ridiculous I've seen this week, and I just came from the WaPo and NYT websites where I was reading about the latest antics of the current U.S. administration. Beyond temperature and humidity, most people, especially people who sleep alone, have no way of figuring out any sleep quality symptoms or causes. Things like snoring and sleep apnea simply cannot be detected when you are not awake.
I think it's a fair question whether or to what extent devices like Beddit can really help you improve your sleep, but they can certainly help spot symptoms that may require assistance.
