Understanding the Link Between Humidity and Asthma

Published

on

Ever wondered why your asthma feels worse in Dubai’s hot summers? Blueair’s General Manager for the Middle East and Africa, TR Ganesh explains how the weather plays its part – and offers some tips for asthmatics to survive the summer

Stepping outside for even a few minutes can leave you feeling sticky, while your clothes often seem to be instantly soaked through. But beyond the need for extra hydration and increased laundry bills, the UAE’s legendary humidity brings with it several health concerns.

Those suffering from asthma and frequent allergies are often the worst hit. Hot and humid weather, particularly when the amount of water vapour in the atmosphere crosses 50 percent, has been linked to increased asthma attacks.

Researchers at the University of Kentucky Medical Center have shown how when patients breathed air that was controlled for temperature and humidity levels, asthmatics faced greater airway resistance than non-asthmatics, while hotter and damper air led to a greater frequency of coughing attacks.

In a separate study of more than 25,000 asthma-related clinic visits, analysts at Children’s Hospital of Michigan found that a simple 10% increase in humidity was linked to one extra emergency visit at the clinic, and a 10-degree ascent in temperature brought about two extra asthma visits.

Those findings help explain why asthmatics in the UAE often have such a hard time in the muggy summers. Humidity over the coming weeks is expected to touch 80% in the country’s coastal areas, even as the hazy conditions are set to continue.

Atmospheric moistness levels over 60% offer the perfect breeding ground for mould and dust mites, some of the most typical asthma triggers. Air pollution also increases with a rise in humidity, and ozone molecules, with their detrimental effect on lower lung function, are a particular concern.

However, another major contributor is the temptation to stay indoors at a time the mercury touches its annuals highs. Not only can air-conditioning units harbour up to 1,000 dust mites and 250,000 allergenic dust mite faecal pellets, triggering respiratory allergies, but indoor air is up to five times more polluted than outdoor air, according to the US Environmental Protection Agency. Most people around the world spend 90% of their time indoors and must, therefore, remain alert to the quality of the air they are breathing.

Indoor air pollution is caused by everyday activities such as cooking, use of cleaning and hair products, air fresheners, candles, open fires, and smoking. In addition, outdoor air enters homes and workplaces through ventilation. Exposure to indoor air pollution can lead to a wide range of diseases including acute and chronic respiratory conditions such as chronic obstructive pulmonary disease and pneumonia, lung cancer, ischemic heart disease, stroke, and cataract. Polluted indoor air can also trigger asthma and allergies.

Besides seeking medical advice, a number of precautionary measures can help improve indoor air quality and with it, allow asthmatics to breathe easier. These include:

  1. Open the window – your indoor air is on average five times more polluted than the outside air.
  2. Vacuum frequently and regularly wash beddings and other textiles.
  3. Reduce or remove carpets, which trap unhealthy particles such as dirt, fungi and dust mites.
  4. Avoid unnecessary chemicals – use natural cleaning products instead.
  5. Cut down on the use of perfume and hair spray.
  6. Invest in plants – according to NASA, English ivy and Peace lily best eliminate household pollutants.
  7. Put a certified asthma-approved air purifier in the rooms, where you spend most of your time.

The World Health Association (WHO) considers air pollution to be the single biggest environmental risk to human health with 9 out of 10 people in the world breathing polluted air. However, with a few preventive measures, asthmatics don’t need to be limited by the summer’s extreme temperatures and high humidity.

Top 10 Steps to Securing Your New Computer

Published

on

Written by Phil Muncaster, guest writer at ESET

With Windows 11 making headlines for all the right reasons, it could be a great time to invest in a new PC for the family or the home office. But any new household computing device should come with an attendant safety warning. Hackers will be after your data the minute it’s connected to the internet. And they have numerous ways to get it.

That’s why you need to think about cybersecurity even before plugging your machine in and switching it on. Take time out now to refresh your memory and make cyber-hygiene a number one priority.

What are the main threats to my PC?
As soon as you’re connected to the internet, malicious actors will be looking to steal your data, encrypt and hold your machine ransom, lift financial details, secretly mine for cryptocurrency, and much more. They’ll do so via some tried and true methods, which often rely on cracking, stealing or guessing passwords, or exploiting software vulnerabilities. Top threats include:

Phishing: One of the oldest con tricks in the book. Cybercriminals masquerade as legitimate and trustworthy sources (banks, tech providers, retailers, etc) and try to persuade users into clicking on links and/or open attachments in emails. Doing so will take users to a spoofed site requesting that they fill in personal information (like logins and/or address/financial details) or could trigger a covert malware download.

Drive-by downloads and malicious ads: Sometimes merely visiting an infested website or a site running a malicious ad could trigger a malware download. We may think that well-known sites may be less compromised in this way as they are better resourced and can afford enhanced protection. But there have been plenty of counter-example through the years showing that it’s not always the case. That’s why its essential to invest in security software from a reputable provider and ensure that your browser’s security settings are correct.

Digital skimming: Hackers may also compromise the payment pages of e-commerce sites with malware designed to silently harvest your card data as it is entered. This is difficult to guard against as the issue is with the provider. However, shopping with better-known sites can reduce risk.

Malicious apps and files: Cybercriminals also hide malware inside legitimate-looking applications and downloads. Many of these are posted to online forums, P2P sites, and other third-party platforms. That’s why it makes sense to download only from trusted sources, and to use an effective security software tool to scan for malicious software.

Ten tips to keep your computer safe
Many of the below steps may be taken care of automatically by your PC manufacturer/Microsoft, but it pays to dig a little deeper to make sure all the settings are as secure as you need them to be. Here are our top 10 tips for computer safety:

  1. Apply automatic updates for the OS and any software running on the PC
  2. Remove bloatware that often comes with PCs. Check beforehand if you don’t recognize any software to ensure removing it won’t degrade the performance. The fewer pieces of software on the machine, the less opportunity for attackers to exploit bugs in it
  3. Install multi-layered security software from a reputable third-party vendor and keep it up to date
  4. Configure backups, and ideally back up a copy of data to a remote storage device kept offline
  5. Secure the browser by adjusting privacy and security settings and ensuring it is on the latest version
  6. Switch on and configure your firewall on the OS and home router, ensuring it is protected with a strong password
  7. Download a multi-factor authentication app in order to help protect your accounts from being hijacked via phishing and other attacks
  8. Avoid using USBs that you don’t own, in case they are loaded with malware
  9. Use a password manager to ensure that all your credentials are unique, strong, and hard-to-crack
  10. Only download apps/files from trusted sources and avoid pirated material, which can often be booby-trapped with malware

It goes without saying that, even by following these best practices, you could still be at risk when browsing online. Always proceed with caution, don’t reply to unsolicited emails/online messages, and ensure device encryption is switched on.

Why You Should Use a VPN While Traveling

Published

on

According to a survey conducted by NordVPN, 50% of travellers use public Wi-Fi while on the road. However, only 20% of them use a VPN (a virtual private network) to protect themselves while being connected to a public network. “Travelers connect to public Wi-Fi in airports, cafes, parks, and trains. Some even use public computers to print their visa information or flight tickets. A VPN in those cases is crucial if you want to make sure that your vacation will not be ruined by cyber criminals. Nobody wants to lose access to their device or their bank account during a trip to a foreign country,” says Daniel Markuson, a cybersecurity expert at NordVPN.

As International VPN day (August 19th) is just around the corner, Markuson lists all the benefits offered by the service.

Enhanced online security
The main purpose of a VPN is to keep its user’s online connection secure even when they are away from home. Hackers can set up fake hotspots or access unsecured public routers and this way monitor users’ online activity. Once a user is connected, criminals can intercept their internet traffic, infect the device with malware, and steal their victim’s personal information.

When authenticating themselves on public Wi-Fi, users often need to type in their email address or phone number. However, if a user has accidentally connected to a hacker’s hotspot, they could be exposing themselves to real danger.

A VPN hides users’ IP addresses and encrypts their online activity. That means that, even if a user is using a malicious hotspot, the hacker behind it won’t be able to monitor their activity. Therefore, getting a VPN for travelling abroad is essential if you want to stay secure and private online.

Grab the best deals
Depending on the country in which you’re located, the prices for airline tickets, car reservations, and hotels might vary. That’s because businesses know that people in different countries can and will pay higher amounts for certain products and services. If you use a VPN for travel, you can hop between servers in different countries and find the best deals available.

Make the best of additional VPN features
As the industry is evolving, many VPN providers add new features to make their users’ experience even more wholesome. NordVPN, for example, recently added the Meshnet feature that lets travellers connect to other devices directly no matter where in the world they are. This enables users to form a remote connection with their home or office PC from anywhere in the world to share files or for other uses.

However, having said that, please check local laws and regulations about using VPN services on your devices, before you do.

Social Media Data Leaks Account for 41% of All Records Breached

Published

on

Written by Edward G, Cybersecurity Researcher and Publisher at Atlas VPN

Social media is quickly turning into a primary security weak point. A single data breach within one of the major social media networks can result in millions of records being stolen. Within the past few years, we have seen multiple large-scale data breaches involving companies like Facebook and Twitter. Yet, we rarely see the bigger picture.

Luckily, data presented by Atlas VPN gives insight into the scope of the issue. It turns out that 41% of all compromised records in 2021 originated from social media data leaks, which is a significant upsurge compared to 25% in 2020. The data presented is based on the 2022 ForgeRock Consumer Identity Breach Report, which gathered data from various sources, such as 2021 Identity Theft Resource Center, IBM Ponemon, TechCrunch, Forrester Research, as well as UpGuard, and IdentityForce.

A few other factors make social media a security weak point within the current online landscape. First, criminals can prey on business clients by posing as the company in order to obtain credentials. This is becoming especially prevalent since companies increasingly use social networks to communicate with customers.

Second, fraudsters frequently attempt to infiltrate businesses by leveraging mutual connections, which create a false sense of security. Moreover, people who overshare on social media make it simple for thieves to locate personal information that aids in company breaches.

Besides social networks, another major source of leaked information is the retail sector, which accounted for nearly a quarter of all records breached in 2021. According to the U.S. Department of Commerce Retail Indicator Division, e-commerce sales increased by 50% during the pandemic. Retail data breaches increased in frequency and severity during the same period.

While the average cost of a retail breach was $2.01 million in 2020, it increased by 63% to $3.27 million in 2021. Customer credit card, payment information, and personal data were the principal targets of retail data breaches. E-commerce websites and applications sometimes skip security precautions like two-factor authentication (2-FA) as they seek a simple user experience.

When the enormous volumes of personal data that retail websites collect are not adequately protected, it creates the ideal environment for breaches and subsequent fraud. Finally, the healthcare sector is worth mentioning with only 1% of records, yet, at the same time, the information leaked is usually particularly sensitive.

Data compromised from healthcare institutions tend to include name, address, SSN, date of birth, and, in two-thirds of the breaches, actual medical history information. With this information in hand, cybercriminals can blackmail companies or even particular individuals.

To round up the findings, it’s obvious that retail and social media companies should go the extra mile in securing their customer information. In addition, even though healthcare providers leak only a fraction of the data, they should still safeguard their client data with particular care due to the sensitive nature of the information.

Some services offer data breach monitoring tools. Data breach monitors track any data breaches related to your online accounts. It automatically scans leaked databases and informs you of any past or recent breaches where your personal information was exposed.

As always, we must mention the most effective countermeasure against data leaks. It is advised to enable multi-factor authentication on all of your accounts that offer the functionality. This way, even if your credentials are compromised, threat actors will not be able to access your account unless you lose your phone, and it is also found by ill-meaning individuals, which is less than likely.
