Health Smart Watches
How Does Smartwatch Monitor Body Health Indicators?
In this article we will briefly talk about and introduce some of the major health monitoring techs that are equipped on advanced health smartwatches. These methods of non-invasive heart rate measurement have been commercially used by wearable devices or have the potential to be commercially available: photoelectric volume (PPG), electrocardiogram (ECG). PPG is a technical term for shining light into the skin and measuring the amount of light that is scattered by blood flow. Essentially, PPG works as follows: The sensor first emits a certain wavelength of light (typically green light to measure heart rate), and then the intensity of the reflected or transmitted light is measured by a photodiode. Skin, bones, meat, fat, etc. are fixed in the human body, and so is the volume of capillaries and veins. This is why the intensity of the reflected light is relatively fixed. Only the vascular volume A fluctuates and changes with the pulse, and the reflection of the blood from this part to the light fluctuates as well. We're primarily interested in this fluctuation as it is a measure of our pulse, which is the same as our heart rate. At present, the photoelectric volume (PPG) method is the most widely adopted. One of the biggest advantages of PPG method is that there is very low contact required between the sensor and the skin, even if the sensor and the skin are so loose that there is no direct contact, and as a result, there is an air gap between the sensor and the skin, the sensor still gets a signal-to-noise ratio which is relatively ideal. Wearable devices that can be worn loosely are very popular to users, since sensor that are put too much pressure on skin will cause discomfort to people. When determining the heart rate, electrocardiogram (ECG) is an accurate method to use. It is the top choice when determining heart rate measurements. It is primarily used in some heart rate measurement products used during strenuous activity, such as a heart rate belt. To pump blood to the trunk, the sinoatrial node of the heart contracts and relaxes rhythmically. A control signal is an electrical signal that spreads gradually to the surface of the body and can be measured with electrodes on the skin (human nerve signals are all expressed as electrical signals on nerves). A heart beat is represented by this rhythm. In addition, the ECG signal can also provide a lot of reference information for the doctor's diagnosis. In the past, it was mainly used in professional medical fields. It can be used to help diagnose various heart diseases, such as myocardial ischemia, myocardial infarction, etc., or the pacing conditions of patients with artificial heart disease. , To help doctors better understand the patient’s heart health, so as to make accurate and effective treatments in a timely manner. From a professional point of view, smart wearable devices are very important for detecting arrhythmias and monitoring the electrical activity of the heart. However, for the diagnosis of symptoms, professional testing equipment and professional medical personnel are still needed. At present, most of the wearable ECG monitoring devices purchased by ordinary people are single-lead ECGs, which are susceptible to interference from various external signals, such as poor skin contact and surrounding electronics. Equipment interference, etc., cause the accuracy of diagnosis to decrease. Therefore, from a professional perspective, the diagnosis of abnormal cardiac electrical activity requires more professional equipment and medical personnel. For example, for atrial fibrillation screening, European cardiology recommends wearable ECG Equipment, but the diagnosis of atrial fibrillation requires a standard 12-lead ECG or a non-interference single-lead ECG with a recording time of more than 30 seconds." However, smartwatch monitoring device can obtain user's own ECG data to assess whether the heart is healthy. Or there may be symptoms or risk factors of heart discomfort, so this device is needed for monitoring and data collection. The second situation is to use this type of equipment for follow-up and monitoring of disease treatment effects. Some people need to use this type of equipment to monitor the effectiveness of treatment and whether the disease has recurred after receiving drugs or surgery for cardiovascular disease. Wearable smart ECG devices are an important method for the early diagnosis of heart disease in the future. It is the future direction of medical development to reduce the disability and fatality rate of cardiovascular diseases. It is still necessary to communicate with professionals in a timely and effective manner to ensure the correct interpretation of recorded data and avoid misdiagnosis or missed diagnosis.

Is There a Smartwatch that Monitors Blood Sugar
With the continuous intake of high-sugar foods, the number of diabetic patients is increasing. As a wearable device with health monitoring functions, smart watches are becoming more and more popular. Is there a smartwatch that monitors blood sugar? The answer is yes. Many smart watches on the market now have specific functions of monitoring blood sugar. This article will tell how smart watches monitor blood sugar. Normal blood glucose In the human body, blood glucose levels are tightly controlled and are usually maintained at around 90 milligrams per deciliter (5mmol/L). The normal range is 4-7 mmol/L, that is, the constancy of blood glucose. The normal amount of glucose in the circulating blood is 3.3-7.05 grams (assuming a human blood volume of 5 liters, equivalent to the average man's). Blood sugar levels rise one to two hours after eating and fall to their lowest levels after sleep. Harm of abnormal blood glucose Maladjustment of blood glucose levels can lead to a variety of diseases. Such as hyperglycemia with persistent blood sugar concentrations that are too high and hypoglycemia that are too low. Persistent high blood glucose from a variety of causes leads to diabetes, which is the most significant disease related to blood glucose levels; Lowblood glucose can cause symptoms such as dizziness, inability to concentrate and even shock.In addition to glucose, the blood actually contains certain amounts of fructose and galactose, but only the glucose concentration level can be used as a signal for metabolic regulation (regulated by insulin and glucagon). How to maintain normal blood glucose If you're a foodie, I'm sure you'll start preparing three meals a day on a regular basis for good health. You should limit your daily sugar intake and try to include a mix of starches, fruits and vegetables, proteins and fats at each meal. Pay attention to the type of carbohydrate you choose.Exercise can make people strong, exercise can drive away disease. Check blood sugar levels before, during, and after exercise, especially if insulin or hypoglycemic medications are used. Exercise may even lower blood glucose levels a day later, especially if you try new activities or increase the intensity of your exercise. Be aware of the warning signs of low blood glucose, such as feeling shaky, weak, tired, hungry, top-heavy, irritable, anxious, or confused.If you're health-conscious, you might want to buy a device to monitor your blood glucose. But some devices need to collect your blood to monitor blood glucose, which can be very unpleasant. You could use a smartwatch to monitor your blood glucose levels. The watch monitors your blood glucose around the clock and automatically measures it every 5-10 minutes. This will prevent you from forgetting to measure your blood glucose and avoid the pain of inserting a needle. The data monitored by the smartwatch is uploaded to the APP. You can check the data at any time and keep track of the changes in blood glucose.

How Can You Make Sure Your Blood Sugar Test Is Accurate?
Normal blood glucose value refers to the blood glucose value of 3.9 ~ 6.1 mmol/L during fasting, which has guiding significance for the treatment and observation of diseases. Fasting plasma glucose of more than 7.0 mmol/L is likely to be diabetic. Factors affecting blood sugar value There are many factors that affect blood sugar, and the following are the most common ones in life:1.Improper diet; Excessive intake of staple food, excessive intake of oil and other factors caused postprandial blood sugar;2. insufficient exercise; Not having the time to exercise, not wanting to exercise or having a chronic illness that interferes with exercise can affect blood sugar;3. bad mood; Tension, anxiety, anger, and over excitement can cause blood sugar to rise;4. improper drug use; Insufficient or excessive medication, intermittent medication, incorrect use of drugs, etc., can affect the rise of blood sugar;5. stress factors: cold fever, severe infection, trauma, surgery, acute myocardial infarction or stroke caused blood sugar fluctuations;6. climate change: cold stimulation can make hyperglycemic hormone secretion, cause blood sugar rise; The weather is hot, metabolism is accelerated, blood sugar is lower than usual, but hot day is easy to sweat, sweat more blood is easy to sticky resulting in blood sugar rise;7. glucotropic hormones: islet glucagon, glucocorticoid, adrenaline, etc., can cause blood sugar rise. How to monitor blood sugar is accurate When testing blood sugar, if you want accurate blood sugar value, you should avoid the factors that affect blood sugar listed above. You need to turn on the smartwatch automatic all-weather monitoring function and check the data in the APP. The APP calculates an average blood sugar level for a day. To improve accuracy, you can also use the calibration feature. In the private mode of APP blood sugar function, record data 7 times a day. The following is the recommended time point: Test blood sugar after waking up in the morning Test blood sugar after breakfast Test your blood sugar before lunch Blood sugar after lunch Test your blood sugar before dinner Test your blood sugar after dinner Test your blood sugar before bed The average value is obtained after the calibration value is entered. By comparing the data, you can see how your blood sugar fluctuates. You can effectively control your daily diet, activity and other habits to improve blood sugar.If you want more accurate numbers, you'll need to wear the smart watch for more than three days while you spend time analyzing the data. The longer the record, the closer the blood sugar is to the exact value. Non-invasive blood glucose techniques Non-invasive blood glucose monitoring technology is a combination of electrophysiological technology, PPG green light monitoring and AI technology.

Are Smartwatches Accurate for Heart Rate?
Smart wearable technology use has become increasingly prevalent over the past decade. For example, smartwatches are frequently being used to measure and monitor people’s heart rate. A person who has been using a smartwatch to monitor their heart rate can give that data to their doctor, who can potentially use it to make diagnoses. But are smartwatches really accurate for heart rate? In this blog, I will explain the principle of monitoring heart rate in smartwatches, thus aiding in better understanding the issue of smartwatch heart rate accuracy. How does a smartwatch monitor your heart rate? Smartwatch usually uses a optical heart sensor to measure your heart rate, which is also called photoplethysmography (PPG) technology. It typically works by shining light onto the skin and using photodiodes to detect the amount of blood flowing through your wrist. Blood is red because it reflects red light and absorbs green light. When your heart beats, the blood flow in your wrist will reflect red light and which can be absorbed by the flashing green light on smart watches. Then smart algorithm uses changes in light reflection caused by blood flow through the the wrist to calculate the heart rate. In this manner, it is usually possible to accurately monitor heart rate. Are chest straps more accurate than smartwatch heart rate monitors? Before smartwatches, only way to monitor heart rate was a chest strap. The chest straps are widely recognized as the best heart rate monitor device, with 99.6% accuracy when worn correctly. Unlike the smartwatch, a chest strap heart monitor uses electrocardiography to record the electrical activity of your heart. It is done by two diodes located on the chest strap, which picks up the electric signal and then sends an electromagnetic signal containing heart rate data. The chest strap is very accurate because it directly measures the electrical activity of the heart, while optical heart sensor used by smartwatches measures the secondary occurrence – flowing blood. How is the smart watch heart rate accuracy? In fact, chest strap heart rate monitor is really more accurate than smart watch heart monitor. However, since they require a moisture-water pad to pick up an electric signal, which makes it more challenging to use than smartwatch. From a scientific point of view, the PPG technology used in smartwatches can also accurately detect heart rate in principle. Since the optics takes measurements from a wrist, it is may affected by vibrations, shocks, so it cannot be relied on in some conditions. But if you tighten the sensor well on your wrist, it can be said that it should be as accurate as a chest strap. Can smart watch detect irregular heart beat? One of the most common irregular rhythms detected by personal devices is atrial fibrillation (AFib). And whether performed in a doctor's office or via a portable device worn at home, we've used electrocardiogram (ECG) to help detect AFib. Many smartwatches have a built-in ECG sensor, which uses LEDs flashed against your skin to detect blood flow and measure your heart rate. Sensors collect this information and algorithms process it to make sense of your heart's rhythm. Your smartwatch takes these measurements day and night, if an irregular rhythm is detected, it sends you an alert. Conclusion With the further development and maturation of PPG technology, the monitoring of heart rate by smartwatches will become increasingly accurate. Compared to traditional heart rate monitoring devices, smartwatches are more convenient to use, allowing for on-the-go monitoring anytime, anywhere. They can also provide urgent notifications for irregular heart rates, which represents a significant advancement in health monitoring. Credor has been dedicated to heart rate sensing technology for decades, committed to offering cost-effective ECG smartwatches that accurately monitor heart rates, along with various best smartwatch for health monitoring, to accompany and safeguard your well-being.
