Like many people, perhaps, it's time for you to decide to spend less time on your phone. It is a good idea because there is scientific evidence to show that spending time on smartphones is destroying sleep, memory, relationships, ability to concentrate, creativity and solving. Your decision and decision.
However, that is not all. Scientists claim that regular use of smartphones can increase cortisol, the hormone that causes stress. The use of phones now threatens health, even shortening the lives of users, the New York Times said.
At the moment, most discussions around smartphones focus on dopamine, a substance produced in the brain that helps people form habits, or in other words, addiction. Just like slot machines, smartphones and applications designed for them are clearly intended to trigger dopamine production, making it difficult for people to put them down.
The effects of dopamine are the reason why many experts voiced warnings about phone addiction. However, dopamine is still just the tip of the iceberg. Demonstrating the phones that increase cortisol hormones can make smartphone use even more alarming.
Cortisol is a hormone that can cause many effects. This hormone release activates physiological changes, such as increased blood pressure, heart rate and blood sugar. In an emergency, cortisol helps the body respond immediately to life-threatening threats.
Cortisol will definitely be useful in case you are in physical danger, such as being attacked by a bull. However, it will be bad if cortisol is produced when you use the phone. Checking email and getting an angry email from your boss also makes you nervous about emotions, just like when your body is at risk.
If only occasionally happens, there is nothing to worry about when your body produces cortisol at the phone. However, an American spends an average of 4 hours a day looking at the smartphone screen and keeping it at hand anytime, anywhere, even when sleeping. The result is smart phones, equipped with a full range of social networking applications, email and news reading, making people obliged to keep working, creating unintended stresses.
David Greenfield, a professor of psychiatry at the University of Connecticut School of Medicine, emphasized: "The level of cortisol increases when your phone is in sight or nearby, when you phone or even think. "It's a stressful and unpleasant reaction, causing the body to resist by checking the phone to help the stress go away."
Thus, checking the phone will make you soften for a second but can make things worse for a long time. Whenever you check your phone, you may see something stressful waiting for you, leading to cortisol fluctuations. That's why you always want to check your phone to reduce anxiety. This cycle will continue to lead to chronic cortisol increase.
Chronic cortisol elevation is the crux of the problem. It causes serious health problems such as depression, obesity, diabetes, blood pressure, heart attack, memory loss and stroke. Dr. Robert Lustig, professor of endocrinology at the University of California, warns: "Every chronic disease we know will be aggravated by stress. The phones contribute to this." .
In addition to the long-term health effects, stress caused by smartphones can affect us in life-threatening ways immediately. Increased levels of cortisol weaken the prefrontal cortex, an important area of the brain responsible for making decisions and rational thinking.
"The forehead cortex is extremely important. It helps us not to do stupid things," Dr. Lustig said.
The decline of the prefrontal cortex reduces the ability to control itself. When the body suffers from excessive stress originating from smartphones, people tend to do something to relieve themselves. Stupid actions, such as texting while driving, can cause users to die just because of immediate stress relief.
The impact of stress can be further amplified if we constantly worry that something bad is about to happen, whether it's a physical attack or an angry commentary on the social network. Sometimes, people even feel the phone vibrates in their pockets despite the fact that it is not in it.
"Everything we do, everything we experience can affect physiology and change the blood vessels in the brain in a way that makes us react to less or more stress," Bruce McEwen, head of the Department. The Rockefeller University neuroscience, said.
Dr. McEwen also stressed that our basic cortisol level will increase if we sleep less than 7 or 8 hours in a 24-hour cycle. Checking the phone before bed makes the body more or less affected by the regulation of cortisol levels, causing long-term health risks.
The good news is that if we can break this anxiety cycle, we can reduce cortisol levels, which help improve health status and minimize risks from long-term stress. Over time, Dr. McEwen said, it can even restrain our brains so that we no longer feel stressed when we don't use the phone.
To realize this, turn off mobile notifications except for things you really want to receive. Next, pay attention to how individual applications make you feel you need to use them. Hide these applications from the main screen or even better delete them in a few days to check your own feelings.
Also, pay attention to how individual applications impact you. Dr Judson Brewer, director of Brown University's Mindfulness Research and Innovation Center, said: "If we can't perceive physical problems, we won't be able to change our behavior. and anxiety often manifested by chest contractions ".
Regular breaks are also an effective way to balance your body's chemistry and regain control. Stopping using the phone for a certain period of time or leaving them away from the dining table can be a step in the right direction.
Also, try not to let your phone cravings be satisfied. Although it's not easy, this is really a long fight for you to feel better every day, though it may take time to realize it. Above all, it can help us live longer, literally.
