Are fitness bracelets harmful to health? Radiation harm

Are the functions of fitness bracelets harmful or are these gadgets completely safe for human health? an issue that is the subject of discussion among athletes and doctors of different profile specialties. Electronic devices of this type equipped with multifunctional programs that analyze the vital signs of the body.

Fitness trackers are compact and easy to use on a daily basis.

What are fitness bracelets and why are they needed?

A fitness bracelet is an electronic device that fastens on the surface of the wrist and looks like a wristwatch. Under the body of this gadget, there are many ultrasensitive sensors that monitor the physiological state of the body. Any changes in the work of the heart and blood vessels, activation of the functions of the musculoskeletal system are recorded by the programs of the fitness bracelet.

The purpose of this device is to monitor the health status of adults and children of all age groups, or tracking the level of performance of the heart and blood vessels during peak loads. Most doctors, professional athletes and trainers believe that this type of gadget is not harmful to health.

The table below describes the basic functions of fitness bracelets, which help to effectively monitor the vital signs of the body.

Purpose of fitness bracelets	Feature characteristics
Control of heart rate and blood pressure	Fitness bracelets are equipped with heart rate monitors that record the heart rate. The electronic device monitors changes in blood pressure during moments of physical calm, as well as during training in the gym.
Counting steps	The built-in accelerometer allows you to use your fitness band as a device to measure your total steps taken throughout the day. This function is especially useful for people who try to lead an active lifestyle, pay attention to the prevention of cardiovascular diseases, and fight overweight.
Sleep monitoring	Sensitive sensors of the fitness bracelet monitor the duration and quality of a person's sleep at different times of the day. With this option, you can adjust the rest periods so that the body gets a full recovery.
Track your physical activity level	Running long, medium and short distances, hiking, swimming in the pool and open water, riding cycling - these are different types of physical activity that are identified and then analyzed by programs fitness bracelets. The electronic device has the function of comparing current sports loads with the performance indicators of the user's heart and blood vessels.
Collecting calorie expenditure data	Wearers of fitness bracelets no longer need to keep a diary of calorie consumption and expenditure. This gadget independently determines the amount of energy that was spent during the day.
Sending sports notifications	An important function of monitoring general health is the synchronization of an electronic device with a mobile phone, as well as sending sports notifications. For example, a gadget can send a message to its owner when it is necessary to start strength training of muscles, or take a break to restore the body.

Fitness bracelets are most popular among men and women in the 20-40 age group. Most of the users of these gadgets are young and energetic people leading an active lifestyle who combine work in an office with regular sports activities, monitor their health and prevent excess weight gain body.

The impact of fitness bracelets on health

Whether fitness bracelets are harmful to health, or completely safe for all parts of the body - this is a question that requires additional study with the involvement of doctors and technical specialists.

For a healthy person

For a completely healthy person who does not have diseases of the cardiovascular, respiratory system, does not suffer from neuropsychiatric disorders, as well as pathologies of the musculoskeletal system, a fitness tracker is just an assistant in daily life.

This device is not intended to be a one-stop-shop for weight loss, endurance, or muscle gain. A fitness bracelet only collects and organizes information about a person's lifestyle, level of physical activity and vital signs of the body.

In healthy people who have internal psychological complexes, they are too dependent on information, coming from a fitness tracker, the following disorders can develop:

• chronic fatigue syndrome, when the wearer of the bracelet sets a goal to exceed the physical the load that was reached the day before (for example, do not 7000, but 8000 steps, run much more distance);
• eating disorders due to too close control over calorie expenditure;
• critical weight loss;
• the development of cardiovascular diseases caused by chronic overwork of the body;
• nervousness and increased irritability;
• the formation of a complex of low self-esteem (similar psychological problems arise in weak individuals who, due to individual physical data, are not able to maintain a high rhythm of physical activity).

A healthy motivation for sports, an active lifestyle and the use of a fitness bracelet allows you to maintain stable operation of internal organs and life support systems of the body without the risk of developing neuropsychiatric disorders.

For pregnant

Whether fitness bracelets are harmful to the health of expectant mothers, or whether they are completely safe is a question that has been studied by technicians, specialists in the field of pediatrics, obstetrics and gynecology. These devices are not dangerous for women who are pregnant or breastfeeding a newborn baby.

An electronic gadget records the vital signs of the female body without scanning the body. Fitness trackers are not a source of ionizing radiation, and they also do not generate waves that are hazardous to health. These gadgets are made of high quality silicone and hypoallergenic rubber, which eliminates the risk of toxic substances and the development of an allergic reaction.

For people with pacemakers

The heart rate monitor of the fitness bracelet records the heart rate, but does not affect its electrical impulses. The counting of heartbeats is carried out using LEDs and special photocells. These sensors scan the top layer of the skin, and then determine the contractile activity of blood vessels.

Based on the data obtained, the objective heart rate is calculated. The fitness tracker does not come into contact with the chest surface of the wearer with a pacemaker. Therefore, this gadget is not only completely safe for people with the most severe heart diseases and blood vessels, but also useful as an additional means of effective control over the condition health.

For a person with health problems

Are fitness bracelets harmful to health, or are they completely safe - this is the question that worries men and women with acquired diseases of the heart, respiratory system, digestion, circulatory vessels.

Fitness bracelet software records the vital signs of healthy people, as well as users who have acute or chronic diseases of the body. Subject to correct operation of the tracker and an adequate assessment of the information coming from its display, this device is not capable of causing a deterioration in well-being.

For people with health problems, fitness bracelets are useful for the following functions:

• motivate the user to lead an active and healthy lifestyle;
• control the work of the heart, and also display blood pressure indicators in real time;
• help control weight, warning the user about a low level of physical activity, insufficient consumption of calories;
• contribute to an increase in previously achieved sports results (for example, if a person has chronic diseases of the body, in which moderate physical activity is not contraindicated);
• by tracking the phases of sleep, they allow you to adjust the mode of rest and wakefulness.

Users with chronic diseases of the heart, blood vessels, respiratory, digestive and nervous systems should not follow all directions from the fitness tracker. This device does not take into account the possible presence of pathologies of internal organs, previously suffered injuries.

Therefore, each user must adapt the current notifications of the gadget to the realities of their health and general well-being. Before using the fitness bracelet, it is recommended to visit your doctor, consult with a specialist for the possible use of physical activity, as well as undergo an unscheduled examination organism.

Is the radiation from Bluetooth harmful?

Bluetooth technology is ubiquitous in almost all electronic devices. This function is also at the heart of the work of fitness bracelets.

This method of transmitting digital information is completely safe for the body of healthy people, users with various medical conditions, women who are pregnant, and nursing a baby breasts. The absolute harmlessness of Bluetooth technology has been proven by the results of laboratory tests, which have confirmed the neutrality of this type of waves.

Is it possible to be in the bracelet all the time

From a medical point of view, there are no contraindications to wearing a fitness bracelet around the clock. Despite this, most experts recommend periodically removing this device in order to so that the skin around the wrist receives enough sunlight, ventilated with air masses.

Do I need to take off my gadget at night?

During sleep, the volumetric models of fitness trackers can be uncomfortable. Therefore, these gadgets are recommended to be removed before going to bed. If there is no need to record the phases of sleep, to determine the quality of rest in the dark, then the use of an electronic device at night is impractical.

How does a smartwatch detect sleep phase?

Human sleep consists of 2 main phases. This is a fast and slow sleep. The last state of the human body is classified into the stage of falling asleep, superficial and deep sleep. These phases alternately change in different periods of the night or daytime rest. Towards the morning, REM sleep becomes more and more superficial, and then goes into wakefulness. To determine the phases of sleep, fitness trackers have 2 electronic sensors. This is a heart rate monitor and an accelerometer.

In this case, sleep quality monitoring is carried out according to the following algorithm:

1. After falling asleep, the person enters a state of deep sleep.
2. The pulsation of the radial artery at the wrist becomes monotonous, and also slows down 1.5 times.
3. The centers of the brain go into a recovery mode and proper rest.
4. The heart rate monitor reads this information, determining the phase of deep sleep, and also records its duration.

In the second half of the night, the human body gradually enters the REM sleep phase. The functional activity of the central nervous system increases, the mobility of the eyeballs is observed, a reflex contraction of the muscles of the musculoskeletal system is possible.

At this stage, the frequency of rhythmic heart beats increases. The heart rate monitor of the fitness bracelet detects changes in the functional activity of the cardiovascular system, and the accelerometer records body mobility. This information is identified as the onset of rapid or superficial sleep.

Why is my fitness tracker showing erroneous sleep data?

The display of non-objective data by the fitness tracker regarding the user's sleep indicates the presence of software errors in the electronic device. The second version of receiving erroneous information about the phases, quality and duration of sleep is a malfunction of the main sensors of the gadget in the form of a heart rate monitor or accelerometer. Users who regularly receive incorrect data on the physiological parameters of the body are advised to conduct a technical check of their fitness bracelet.

Guidelines for the safe use of fitness bracelets

Owners of fitness trackers of various modifications must observe the following rules for their safe use:

• always make sure that the gadget has a sufficient battery level;
• the software of the electronic device must be synchronized with the user's smartphone;
• you cannot swim in the pool, lake or bathtub with the tracker worn on your wrist (except for models with a waterproof function);
• charging the battery of the gadget should be carried out only with the use of original equipment designed for this purpose;
• under conditions of daily use, the bracelet should not be tightly tightened on the wrist, as this can lead to a violation of local blood circulation.

The strap of the fitness tracker is made of hypoallergenic materials. If signs of redness, swelling, skin irritation appear under the bracelet, then you must immediately remove the gadget from your hand, and then seek help from an allergist or therapist.

Fitness bracelets are mobile electronic devices that are not harmful to human health. These gadgets are equally safe for children, the elderly, or patients with chronic diseases of the heart, blood vessels, respiratory system and central nervous system. The principle of the tracker is to read information about the vital signs of the body.

The heart rate monitor measures the heart rate. The accelerometer counts the number of steps, body speed while running, swimming in the pool, cycling. A fitness bracelet helps maintain a stable level of physical activity, prevents the development of obesity and diseases of the cardiovascular system.
