The more smartwatches you wear, the worse your anxiety sleep.
Mental health and emotional adjustment are increasingly being valued, and the more smartwatches are worn, the more they deserve to be understood and cared for. Today, the first thing that many people open their eyes in the morning is to look at their smartwatches and look at their last night's sleep scores: how long they slept deeply, how long they slept lightly, if there was a period of rapid eye movement. What is the core principle of smart watch rings to monitor sleep?
Come and listen to the answer of Dr. Zhang Junpo, Deputy Director of Ear, Nose and Throat Surgery at the Beijing Tsinghua Tsinghua Medical Institute, Deputy Director of the Sleep Medical Center. Zhang Junpo: Our current smartwatch does not directly measure whether or not it is sleeping, it is mainly inferred by some other signals.
Today's smartwatches are more complicated than ever before, and it uses some of the more advanced signals, such as our heart rate variability, to predict whether we can sleep by monitoring our heart rate and pulse wave signals, which is certainly more accurate than ever before, but it is generally based on these signals rather than direct monitoring, so there is no guarantee of 100% accuracy. The most accurate monitoring of sleep structure is only about 70 percent, and cannot be said to be entirely accurate with a sleep clock. There are generally two reasons, one being some signals to judge sleep.
The deviation may be mainly due to which stages or aspects today. It may take longer to judge sleep than our actual sleep time. For example, if a normal person is lying in bed and is relatively calm, but not yet asleep, all our signals, including movement signals, heart rate signals, may slowly slow down and be mistaken for sleep.
Specifically, for some people with sleep disorders, the sleep structure may be very disturbed, and for this watch to speculate, it may be less accurate, can not be taken as a measure of sleep depth, do not worry about this. For the judgment of sleep depth, the accuracy should be relatively worse. So we evaluate the quality of sleep, and we generally think that the most important thing is to have a rhythm, the clock can provide a very good benchmark, about how much time to sleep each day, when to sleep, etc.
Because the main function of sleep is actually to restore our state, for example, the day after sleep is difficult, but the score is high, in fact it is not a good sleep. There is also the fact that we must first exclude some very critical sleep disorders, a large number of patients with severe sleep disorders, especially those with particularly severe sleep disorders, who actually fall asleep very quickly, and who do not sleep very well at night, but in the sleep clock monitoring, they may remember their sleep efficiency very high. So the rating cannot be the only criterion to rule out whether there is a sleep disorder.
Zhang Junpo: It is difficult to use it to diagnose a disease today, but it also has a very critical value, which is that although its accuracy is relatively poor, but its data accumulate and the overall accuracy will increase. For the general public, it is especially important to establish a scientifically rational health concept. In addition, a large number of watches can monitor blood oxygen today, which can actually be used as a very critical screening tool, such as monitoring sleep frequent deoxygenation through a watch, which may actually be a problem, and it is recommended to make further diagnoses.
So the watch has a very critical role today is to be a very critical indicator that can be used as a rhythm, because multi-directional sleep monitoring cannot be guaranteed to be done every day. It has been said that the green light sunscreen of the heart rate sensor has covered the skin, some suspected that the clock leak burns, and others believe that body heat causes cold sores. On the one hand, a lot of people have found that the wrist skin that has been wearing smart watches or rings for a long time is noticeably white, dry, rough, sometimes even hard, thick, with similar manifestations.
What is the real cause of the wrist skin bleaching? Chen Shui: The cause of skin aging or some of the causes of skin cancer is actually ultraviolet waves in sunlight, such as UVA, UVB. Do long-term green light exposure to watch heart rate monitoring accelerate skin aging, causing chromosomal abnormalities?
But this wavelength is concentrated in the short-wave blue light range. Recent studies have also found that some waves of visible light have some chromosomal effects under high-dose long-term exposure. Is there a possibility of leakage causing skin damage when smartwatches are normally worn?
There is no direct scientific evidence that the green light waves emitted by the sensors in our smartwatches are a factor in light aging. If we wear watches with some leakage, the wearer will feel local stinging or numbness for the first time, rather than a chronic long process. Chen Shui: Some substances are allergenic, metal allergenic, allergenic or some ingredients in dyes and additives are allergenic.
What happens after wearing a smartwatch? What happens after wearing a smartwatch? How do you wear a smartwatch and ring every day to prevent skin damage from the habit of wearing?
Some patients say that they are normally not allergic or allergic to cyanide, but after a brief period of sudden appearance of red spots and wrinkles in certain areas of the seatbelt, it is also important to consider whether we did not remove the watch while washing our hands, and the remaining cleansers may cause some irritation to the skin in a short period of time. Chen Shei: If only the area of the seatbelt has, it may be sensitive to some of the composition of the seatbelt, if the whole circle has these reactions, including the plate and the area of the seatbelt, but also think about whether we are wearing too tightly; there is no timely dryness or rubbing after sweating. For tables that need to be worn for a long time, observe carefully if there is any change in the surface of the tabletop material.
From an easily induced situation: cleaning in a timely manner when exercising; washing your face and hands in a timely manner when washing your hands every day. In the stationary state or in the air conditioning room, in winter, wear can be adjusted slightly more tightly; at sports venues or in the hot humid outdoor environment in the summer, the pressure of the tabletop should be relaxed a little and inserted into the range of a finger to monitor the heart rate, and the sensory function of the blood is very moderate. With the corrosion of sweat, the wear of the material, the layer of the membrane on the surface may have been worn out, and some sensitive materials inside exposed to skin sensitivity.
