Do you use headphones or earphones to listen to music or watch videos?
Do you know that the use of headphones can change our mental perceptions and decisions?
This was revealed in a medical study conducted in the United States.
Research from the University of California has shown that the use of headphones not only affects the listener’s sense of hearing but also the mind more than ordinary speakers because it sends sounds ‘inside the head’.
Researchers say that headphone speakers transmit sound as if it were inside your head.
As a result, listeners feel closer to the communicator (person who sings or speaks on headphones) physically and socially, and have a more sympathetic attitude towards them, he said.
According to researchers, these findings will have a significant impact on training programs, advertising and home work.
The study involved experiments and surveys involving more than 4,000 people and found that the effect of headphones on listeners’ perceptions, decisions and attitudes is much stronger than that of ordinary speakers.
Institutions can design their own training programs based on this research, he said.
For example, they may encourage employees to listen to safety training on headphones, which could potentially change their behavior for the better.
Researchers say that headphones also help listeners stay engaged and that they can connect with specific critics or bloggers.
The results of this study were soon published in the journal Organizational Behavior and Human Decision Process.
Millions of people around the world experience stress, confusion and fear of the worst at some point in their lives.
Anxiety is a common human feeling. We all experience this when we are going through a difficult or difficult time.
Fear and anxiety can usually be helpful in avoiding dangers, being alert and facing problems. However, if these feelings become intense or last for a long time, they can stop us from doing what we want to do and as a result our life can be painful.
But did you know that it is very easy to avoid panic ? You just have to increase the water consumption?
Yes, federal medical authorities in Australia have recently hinted that the use of water may help reduce anxiety, which has been the subject of skepticism online.
But medical evidence shows that water and hydration play a role in preventing or controlling panic symptoms.
Why water is useful?
We all enjoy cold water in hot weather because our bodies are designed to let us know when we need water.
A few years ago, a group of medical experts focused on the various effects of water on health, and the results stunned them.
They found that dehydration can lead to negative emotions such as anger, irritability, confusion and stress, as well as a feeling of tiredness.
One trial found that even a slight lack of water increased feelings of anxiety and fatigue.
Researchers also found that people who are accustomed to drinking more water on a daily basis become less relaxed and more stressed if their water intake decreases.
In comparison, people who drink more water feel happier, even if they drink as much water as they want on a daily basis.
Another major study found that drinking 5 or more cups of water a day reduced the risk of depression and anxiety, while those who drank less than 2 cups a day doubled their risk.
A link between dehydration and anxiety in children has also been observed, while dehydration also affects our sleep.
Poor sleep can exacerbate anxiety symptoms.
Effect of water on our brain
About 75% of our brains are water-based, and dehydration reduces energy production in the brain and can alter brain structure.
That is, the brain becomes sluggish and cannot perform its functions properly.
If there is a severe shortage of water, the brain cells will not be able to perform their functions and the brain will have to work harder to complete the task.
Our cells recognize dehydration as a threat to survival, which increases the feeling of nervousness.
Serotonin, a chemical that acts as a link between brain cells, works to stabilize mood and emotions, but its formation is affected by dehydration.
In fact, even a slight dehydration can increase the levels of the stress hormone cortisol in the body, which contributes to a number of mental disorders, including anxiety.
When to consult a doctor?
Looking at the evidence available so far, it can be said that lifestyle changes such as increasing water intake, good diet, physical activity and sleep can improve people’s mental health.
Similarly, the evidence suggests that dehydration affects our mood.
But it is important to keep in mind that there are a number of factors that can affect a person’s anxiety rate, and nothing can completely eliminate these emotions.
This is especially true for people who experience a lot of anxiety. For them, drinking more water will not be so helpful but it would be better to consult a doctor.
VPNs encrypt your internet traffic and disguise your online identity. This makes it difficult for third parties to follow your tracks on the Internet and steal data.
A VPN connection veils your data traffic on the Internet and protects it from external access. Unencrypted data can be viewed by anyone who has network access and wants to see it. With a VPN, hackers and cybercriminals can no longer decipher this data. With the help of a VPN, your activities on the Internet are reliably hidden, even on public networks.
Because the demographic location data comes from a server in another country, your actual location cannot be determined. In addition, most VPN services do not keep logs of your activity. Some providers, on the other hand, log your behavior but do not pass this information on to third parties. With VPN location spoofing , you can switch to a server in another country and effectively «change» your location.
These files require a secure connection for security reasons. A VPN connection is often required to gain access to the data. VPN services connect to private servers and use encryption methods to reduce the risk of data leakage.
A new WiFi standard is being tested by the first companies. This should enable twice the download speed compared to its predecessor. We have summarized the most important information about WiFi 7 for you here.
WiFi 7 is in the starting blocks. The first companies are already testing the new technology, as “teltarif” reports . The standard called IEEE 802.11be will enable a gross data throughput of up to 46 GBit/s. However, the net download speed should “only” be 2.88 Gbit/s. That’s still double WiFi 6, though.
The mandatory introduction of the 6 GHz frequency band is also exciting. This was first introduced in 2020 with WiFi 6E. It was the first innovation in this area in more than 20 years. In 1999, the 5 GHz band was established with WiFi 2 (802.11a).
New WLAN standard: WiFi 7 should start in 2024 at the latest
The Institute of Electrical and Electronics Engineers (IEEE) has been working on WiFi 7 for three years. In order to achieve the higher speed, improved components are required. Among other things, the quadrature amplitude modulation was increased from 1024 to 4096. The channel bandwidth jumps from 160 to 320 MHz.
When exactly WiFi 7 will celebrate its market launch is not yet clear. Some companies are hoping for a start in 2023, while the IEEE is assuming March 2024.
“Alex, I want to talk to the doctor.” This simple phrase adds a whole new level of usefulness to Amazon’s virtual assistant through a partnership with Teledoc. When you say Alexa, you will be connected to the Teledoc call center. From there, Teledoc will call you back for a virtual visit right on your Amazon Echo device. Of course, you can always go to a Teledoc application or website and get the same feature, which means you don’t have to own an Alexa-based device.
Using Teledoc via Alexa will not cost you anything extra, so the price will depend on your insurance.
