Head
At the top of the list of diseases caused by the uncontrolled use of technological equipment. especially those with Internet access, are psychological and reach a growing number of people.
"Repeated behaviors are badimilated by the brain as a source of satisfaction: dopamine, called pleasure hormone," explains Cristiano Nabuco de Abreu, psychologist and coordinator of the Institute of Psychiatry's Technology Dependencies Group ( IPq) of the University of São Paulo (USP)
only eight minutes already allow it.The interaction in the virtual world also activates these brain mechanisms. "This is about the same meaning as people who go to casinos and play slots, "he adds.
Those who are constantly looking for social media, e-mails and chat applications can be FoMO Fear Missing, or "Fear of Missing Something",
Cited for the first time in 2000, it generates anxiety, mood swings, swings, Mood, anxiety and even depression, and affects the children and adults. "The person always wants to know what's new, what his friends and family do and, in the case of posting something, see if he's received any" I like "and comments."
The use of technology in a compulsive way can still lead to loneliness and social isolation, even though it facilitates communication between people [19659002] Another important aspect of the excessive use of electronic devices concerns sleep. Nowadays, many people go to bed with their cell phone, tablet or laptop. With that, the brain, instead of preparing the body to sleep, remains alert and stimulated. At the same time, the light emitted by the screens of the device inhibits the production of melatonin, the sleep hormone.
"We need to disconnect and slow down thinking so that brain waves slow down and sleep returns." Andrea Bacelar, neurologist and president of the Brazilian Sleep Association (ABS), who works with the Brazilian Sleep Association ,
According to the doctor, the symptoms are drowsiness, critical judgment difficult, inability to solve problems, decreased reflexes, irritability, mood swings and increased risk of accidents, of the most simple to the most serious. Already, constant sleep deprivation increases the likelihood of infection and promotes low immunity, weight gain and some diseases, such as hypertension.
Bad nights sleep always have an impact on attention, memory and cognitive abilities and are badociated with depression and growth before the age of one year. It is expected that the peak of growth hormone (growth hormone), the growth hormone, will be produced at night, around two in the morning.
To avoid this, all experts recommend, among other actions, develop a healthy relationship with technology, so as not to become dependent on digital devices. It is also advisable to set hours of use of cell phones, tablets and video games, to decrease activities about an hour before bedtime, to sleep and to wake up at the same time. , the human being blinks every five to ten seconds. However, when you spend a lot of time in front of the video terminals, this action is reduced up to ten times – that's because we are very focused or focused on the activity we are doing.
"Our eye was made to blink" said Dr. Wallace Chamon, a member of the Brazilian Council of Ophthalmology (CBO).
In addition, it is important to lubricate it. In addition, some studies have recently suggested that exaggeration in the use of electronic devices increases the risk of myopia.
One of the explanations for this is that, when we are in front of monitors and screens, we have to make a more accommodating effort nearby, which can cause the growth of the eyeball, which poses the problem of refraction.
There is also the issue of lack of exposure to outdoor environments where the field of view is wider and where the sun's rays stimulate the production of dopamine, a substance that prevents the eye becomes elongated and thus deforms the focus of light that enters the eyeball
Keratitis (corneal irritation) and ulcer can also be caused by the continued use of electronic equipment. To get away from these situations, you must remember to blink; leave the appliances apart every hour, moving away at about 10 minutes; exposed to open environments of four to eight hours per week;
More and more people are using headphones, whether listening to music, programs, news or studying. The problem is that excessive use causes severe damage to the ears.
Ricardo Gurgel Testa, otolaryngologist at Paulista Hospital, São Paulo, states that two factors are responsible: the intensity (or volume) and the time of exposure. "All is well," he says, "and sitting for hours is also very harmful." The consequences are a headache, tinnitus and hearing loss. which can be progressive and irreversible. To avoid them, it is essential to choose a quality accessory, certified by the competent authorities, and to use it sparingly, scrupulously respecting the volume and time limits.
Just to get an idea, at 85 dB, the maximum tolerable daily exposure is eight hours. At 94 dB, two hours and 15 minutes; at 106 dB, 25 minutes and at 115 dB, only seven minutes.
Skin
The sun and pollution do not harm the skin.
As explained dermatologist Fernanda Junqueira, a member of the Brazilian Society of Dermatology (SBD), the American Society of Aesthetic Medicine and the Brazilian Society of Dermatology (SBD). As a specialist of the Brazilian Medical Association (AMB), several studies have confirmed that they can cause or aggravate pigment spots (melasms), especially on the face, neck, neck, and hands , which are the most exposed parts.
This happens because the blue light, part of the visible light that has greater energy, penetrates deep into the skin. "In addition, since artificial lights are related to ultraviolet radiation, they would also be responsible for accelerating aging, which causes genetic mutations in the skin due to dysregulation of their natural physiology and have a negative impact on the skin. 39, DNA cells, "says the doctor.
She also points out that the effects may not be felt immediately, but rather by cumulative action, and they are worse in those who already suffer from melasms, tenderness or skin treatments. .
In these cases, the solution is to keep the skin beautiful and healthy and to protect against damage caused by digital. "This is achieved through the use of a sunscreen with chemical and physical coatings, that is to say with a type of pigment, and it must be re-applied several times during the day , as well as clothes with ultraviolet protection ", explains Fernanda.
The overuse of computers, cell phones, tablets and video games also generates a number of orthopedic diseases.
According to Alexandre Stivanin, orthopedic surgeon and member of the Brazilian Society of Orthopedics and Traumatology (SBOT), they can demonstrate that repetitive typing and play movements cause tendonitis and bursitis among several other lesions or dysfunctions joint. affect the hands, arms and shoulders and cause intense pain, as well as a loss of sensation and strength.
In the case of tablets and smartphones in particular, the person sits long to read and respond to messages.
"By maintaining this bad posture for a long time, we changed the line of force of the weight of the column and changed the center of the balance of the neck.This resulted in muscle fatigue., Damage to the discs of the cervical spine, tingling and a lot of pain, "informs the specialist.
And there is more. Anyone who spends a lot of time sitting in front of a computer, a video game, or television can compromise the knee and back, suffer and limit movement.
However, there are ways to deal with these situations. "It is essential to maintain good body posture when using any type of electronic device, including sitting in an ergonomic chair or having a stand for the column. vertebrae, arms and feet, to direct the arms to penetrate and to keep the equipment out .Stivanin advises
Regardless of this, it is essential to take constant breaks during activities and exercise – stretching, pilates and bodybuilding are great for strengthening and lengthening muscles.
Sedentarism
The Role of Technology in Dissemination of information, including health, is undeniable.However, the increase in the amount of data and the ease of access have caused an obsession for perfect health, with the exception of health. use of medicines, formulas, supplements and technics so-called revolutionary and effective drugs that go against scientific evidence.
sedentary life with the use of digital equipment helps to increase the number of cases of obesity, which has the most dramatic consequences of metabolic diseases (diabetes, for example), changes in cholesterol and cardiovascular diseases, such as hypertension,
"One of the main problems is the low physical movement, a very serious factor, because in addition to gaining body mbad, it causes a loss of muscle mbad that will be very serious over the years, "he said. says Pablius Braga, sports doctor at the Sports Medicine Center of Julho Hospital 9 in São Paulo.
The professional warns that a truly healthy person is essential to have reliable sources of information, to find the time to move in the daily routine and to put on a balanced diet.
