Whether you’re struggling with your work-from-home routine or are feeling overwhelmed by the onslaught of day-to-day stress, keeping your mind active can help you to cope. Staying mentally active can also reduce the risk for cognitive decline as you get older.

When it comes to your mental health, keeping your brain busy has become more important than ever. “Staying busy helps us focus on the here and now, and distracts us from our worries,” says Dr. Divyansu Patel, a psychiatry specialist at TeleMed2U.

Want to take steps toward keeping your brain busy? We’ve got apps for you to try.

Apps, which might range from solving puzzles to learning new languages, can make a big difference in your day-to-day life.

For example, Sam Nabil, the lead therapist for Naya Clinics, says some studies highlight that the practice of learning a new language contributes to cognitive plasticity and improves the brain’s ability to absorb new information.

Meanwhile, linked studies from 2018 and 2019 of more than 19,000 participants found that regularly playing puzzles and completing crosswords or word-based games actually improves brain function.

Mindful meditation — as little as 10 minutes per day — can calm the mind and support body health through positive influences on blood pressure and levels of cortisol (the stress hormone).

So, it stands to reason that finding ways to re-engage and use your brain, such as learning a new language, may help counteract pandemic brain fog.

Read on to find out which apps can help your brain stay busy.

To compile this list, we consulted healthcare professionals, including psychologists and psychiatrists, to discuss optimal activities and apps to help keep people’s brains busy.

We read reviews and recommendations from app users to ascertain which apps were popular, and which appeared to have reported results in these areas:

  • Did users find their stress diminished after using the app?
  • Did the app provide a useful routine?
  • Did users learn a new skill?
  • Was the app useful during the pandemic?

Choosing the best app for your brain really comes down to your personal goals.

Here are some things to consider:

  • Are you trying to sharpen your cognitive abilities and learn new, productive habits?
  • Are you looking for an app to help you manage stress and anxiety or help you sleep?
  • Do you prefer to listen to workshops, personal anecdotes, and inspirational stories to help boost your drive and motivation?

The answers to these questions can help you choose the best app for you.

Many people also find it beneficial to engage with more than one brain app regularly, since different apps help sharpen varying skills, and they really complement each other. For instance, for an overall brain boost, you can learn how to meditate via Headspace while also improving your memory and focus with Lumosity.

What is cognitive training?

Cognitive training involves engaging in regular mental activities, like puzzles or memorization, designed to help maintain or increase a person’s brain function.

Does cognitive training work?

Studies show that mental exercise can actually improve neuroplasticity, the brain’s ability to form and reorganize connections between cells in response to new tasks.

Who can benefit from brain training?

Anyone who is looking to reduce stress, improve cognitive function, or experience a mood boost may find cognitive training helpful. Ongoing studies are specifically looking at how it can benefit people diagnosed with ADHD, those with cognitive impairments, and patients recovering from cancer or even COVID-19.

If you’re feeling burned out or disconnected from your community, finding an app to keep your brain busy may make a difference in your daily life.

Whether you’re a fan of games or hope to learn a new skill such as meditation or another language, now is the perfect time to invest in your brain health.
