What You'll Learn

Playing video games, board games, or card games
Video games, for example, have been linked to better cognitive performance in children. A study of almost 2000 children found that those who played video games for three or more hours per day performed better on tests involving impulse control and working memory. The children who played video games also showed higher brain activity in regions associated with attention and memory. These findings suggest that video games can affect cognitive functions in specific ways, such as improving mental flexibility, planning, and visual working memory.
Board games, on the other hand, offer a different set of cognitive benefits. They require social interactions and the training of specific strategies and actions within the game. While research on the cognitive benefits of board games is still limited, they provide an opportunity to exercise your brain and challenge your mind.
Card games have been shown to improve important thinking skills, such as self-control and the ability to switch between tasks. They provide mental stimulation, requiring players to think strategically, analyse situations, and make quick decisions. Card games can also enhance memory, as they require players to remember the cards played by opponents and those left in the deck. Playing card games can also be a social activity, offering psychological and cognitive benefits, such as reduced loneliness and improved well-being.
In conclusion, playing video games, board games, or card games can offer a fun and engaging way to sharpen your brain. Each type of game provides unique cognitive benefits, from improved impulse control and memory to enhanced social interactions and mental flexibility. Incorporating these activities into your routine can help keep your brain active and healthy.

Learning a new skill or hobby
- Choose a challenging hobby: Opt for a hobby that is mentally challenging and engaging. For example, quilting requires measuring and calculating, which can help improve your memory and coordination. Other challenging hobbies could include learning digital photography, Photoshop, or playing bridge.
- Engage multiple senses: Involve as many of your senses as possible in your learning process. Our senses play a crucial role in learning and memory retention. Try activities that stimulate your sense of smell, touch, taste, sight, and hearing simultaneously, such as baking cookies, visiting a farmer's market, or trying new cuisines.
- Practice regularly: Consistency is key when learning a new skill. Allocate dedicated time each week to practice and improve. For instance, you could spend 15 hours a week, as done by participants in a study by Dr. Denise Park, which showed significant gains in memory improvement.
- Teach others: A great way to reinforce your learning is to teach what you've learned to someone else. Explaining concepts and correcting mistakes helps solidify your understanding and sharpens your brain further.
- Get enough sleep: Ensure you get sufficient sleep before and after learning something new. Sleep helps with memory consolidation, enabling you to recall information more effectively. Aim for 7-8 hours of sleep to allow your brain to optimally process and retain new information.
- Break down complex information: When tackling intricate details or a new skill, space out your learning sessions. Instead of cramming, revisit the information after increasingly longer intervals—start with hourly intervals, then move to every few hours, and eventually review daily. This method improves memory retention and is particularly useful for mastering complicated topics.
By incorporating these strategies into your learning journey, you'll be well on your way to sharpening your brain and enhancing your cognitive abilities.

Getting enough sleep
Sleep is an essential part of our daily routine, and getting enough of it is crucial for our health. When it comes to brain health, sleep is vital for cognitive function, mental acuity, and our ability to concentrate and learn new things. Therefore, ensuring that we get enough sleep is a key step in sharpening our brains.
Firstly, it is important to understand how much sleep we need. On average, adults need around 7-8 hours of sleep every night. However, this may vary slightly from person to person, and it's important to listen to your body and adjust your sleep duration accordingly.
If you're struggling with getting enough sleep, there are several strategies you can implement to improve your sleep habits:
- Create a comfortable sleep environment: Make your bedroom as comfortable, quiet, and dark as possible. Use earplugs or white noise machines to block out noise, and consider using blackout curtains or eye masks to block out light.
- Limit screen time before bed: Exposure to the light from television, computer screens, and smartphones can stimulate your brain and make it harder to fall asleep. Try to avoid screens at least an hour before bedtime.
- Avoid stimulants: Caffeine and alcohol can interfere with your sleep. Avoid consuming caffeine after midday, and refrain from alcohol close to bedtime. Alcohol may make you feel sleepy initially, but it can lead to interrupted sleep later in the night.
- Maintain a consistent sleep schedule: Go to bed and wake up at the same time each day. This helps to regulate your body's internal clock and makes it easier to fall asleep and wake up.
- Practice good sleep hygiene: Use your bed only for sleeping and sex. If you can't fall asleep within 20 minutes, get up and try again later. Avoid naps late in the day, as they can interfere with your nighttime sleep.
- Exercise and diet: Exercise earlier in the day, preferably finishing at least three hours before bedtime. Avoid eating late at night, especially foods that can cause heartburn.
By implementing these strategies and prioritizing sleep, you can ensure that you're getting enough rest. This will not only improve your overall health but also sharpen your brain, enhancing your cognitive abilities and mental focus.

Reducing stress through meditation
Meditation is a powerful tool to reduce stress and sharpen your brain. It is a practice that can be done anywhere and at any time, and its benefits can be felt after just one session.
The body's natural response to stress involves preparing you to fight or flee, which can be helpful in extreme danger. However, prolonged stress can cause physical damage to the body. Meditation triggers the body's relaxation response, helping to calm and repair itself. It quiets stress-induced thoughts and provides direct physical relaxation, making it an effective tool for stress management.
There are various meditation techniques, such as \"mindfulness\" and \"mantra\" meditation, that have been shown to reduce emotional symptoms like anxiety, depression, and stress, as well as improve physical symptoms like pain. Meditation programs have been found to have small to moderate effects on reducing stress and improving mental health-related quality of life.
To incorporate meditation into your routine, start by finding a quiet and comfortable space. Set a timer for a few minutes and close your eyes, focusing on your breath and the sensations in your body. If your mind wanders, gently bring your attention back to your breath. Regular meditation practice can help reduce stress and improve overall well-being.
In addition to meditation, there are other brain exercises that can help sharpen your cognitive skills and enhance your mental sharpness:
- Jigsaw puzzles: Working on jigsaw puzzles recruits multiple cognitive abilities and enhances visuospatial cognitive skills.
- Card games: Playing card games can improve thinking skills, self-control, and the ability to switch between tasks.
- Learning a new skill: Learning something new, like a language, an instrument, or drawing, can strengthen brain connections and improve memory and thinking abilities.
- Challenging your senses: Engage in activities that stimulate your senses, such as baking, visiting new places, or trying new cuisines. This activates more of your brain and enhances memory retention.
- Social activities: Interacting with others through volunteering, classes, or social events improves your mental well-being and sharpens your brain.

Physical exercise
Cognition refers to your overall ability to think clearly, learn, and make decisions. Exercise boosts cognition by increasing blood flow to the brain, delivering essential nutrients and oxygen. It also stimulates the production of brain-derived neurotrophic factor (BDNF), a protein that strengthens synapses and supports the growth of new neurons, enhancing our ability to learn and adapt.
Memory, especially short-term memory, is improved through physical activity. Exercise increases the volume of the hippocampus, the brain structure primarily responsible for memory and spatial navigation. A larger hippocampus means improved memory retention and recall abilities. Additionally, exercise reduces stress and anxiety, which can interfere with memory consolidation and retrieval processes.
Executive function encompasses focus, planning, problem-solving, and managing emotions. Physical activity enhances this domain by promoting neuroplasticity, the brain's ability to form new neural connections and adapt to new situations. It also increases the production of neurotransmitters, such as dopamine and norepinephrine, which are essential for attention, motivation, and emotional regulation.
The recommended amount of physical activity to achieve these brain health benefits is at least 150 minutes of moderate-intensity exercise per week. This can include activities such as brisk walking, cycling, yoga, or even active video games like Pokémon GO. More intense workouts, such as running or high-intensity interval training (HIIT), can further boost neuroplasticity and cognitive gains.
Incorporating physical exercise into your routine is a fun and effective way to sharpen your brain. It not only improves your cognitive abilities but also enhances your overall well-being, making it a valuable addition to your daily or weekly schedule.
