How to Improve Memory: 5 Science-Backed Tips for Better Recall and Brain Health

Learning how to improve memory can help you remember information, strengthen concentration and support long-term brain health. Quality sleep, regular exercise, balanced nutrition, effective memory techniques and mental stimulation can all support cognitive function.

Occasionally forgetting a name, misplacing your keys or struggling to recall information is common. However, frequent or worsening forgetfulness should not be ignored. Understanding how memory works and adopting healthy daily habits can help improve recall and maintain cognitive well-being.

How Can You Improve Memory Naturally?

You can improve memory naturally by getting sufficient sleep, exercising regularly, eating a balanced diet, practising active recall and engaging in mentally stimulating activities. These habits support learning, memory retention, concentration and overall brain health.

Let’s explore five practical, science-backed ways to support memory and cognitive function.

Why Do People Experience Memory Problems?

Memory is the brain’s ability to encode, store and retrieve information. It allows us to learn new skills, remember experiences and access previously acquired knowledge.

Memory involves three essential processes:

• Encoding: The brain receives and processes new information.
• Storage: Information is retained for future use.
• Retrieval: Stored information is accessed when needed.

Forgetting can occur when information is not properly encoded, is difficult to retain or cannot be retrieved. Attention, emotional well-being, sleep quality and overall health can influence these processes.

What Are the Common Causes of Memory Problems?

Everyday forgetfulness does not automatically indicate a serious cognitive condition. Several factors can affect memory and concentration, including:

• Stress and anxiety: Persistent stress can interfere with attention and information processing.
• Poor sleep: Insufficient or disrupted sleep can affect learning and memory consolidation.
• Depression: Low mood and reduced concentration may make remembering information difficult.
• Nutritional deficiencies: Vitamin B12 deficiency, for example, can contribute to cognitive symptoms.
• Medication side effects: Certain medications can affect alertness, attention and memory.
• Age-related changes: Some people experience slower information processing and occasional forgetfulness as they age.

Identifying the underlying cause is important because some memory-related difficulties may improve with appropriate treatment.

5 Science-Backed Tips to Improve Memory Naturally

1. Prioritise Quality Sleep to Improve Memory

Sleep plays an essential role in memory consolidation, the process through which newly learned information becomes more stable and easier to retrieve.

During sleep, the brain processes information acquired throughout the day. Insufficient sleep can affect concentration, learning, attention and the ability to remember new information.

How to improve sleep for better memory:

• Aim for seven to nine hours of sleep each night if you are an adult.
• Maintain consistent sleeping and waking times.
• Reduce screen exposure before bedtime.
• Avoid excessive caffeine, particularly late in the day.
• Create a comfortable, quiet sleeping environment.

Consistent, quality sleep supports learning, attention and cognitive health. It is one of the most important lifestyle habits to prioritise when experiencing everyday forgetfulness.

2. Use Visual Associations and Mnemonic Techniques

Memory techniques help organise information and make it easier to retrieve when needed. Connecting new information with familiar images, words or experiences can make learning more effective.

For example, if you need to remember someone’s name, associate it with a familiar object or visual image.

Useful memory techniques include:

• Acronyms: Use the first letters of words to create memorable abbreviations.
• Visualisation: Connect information with clear mental images.
• Chunking: Divide lengthy information into smaller, manageable groups.
• Association: Link new information with something you already understand.

These techniques can improve information organisation, learning and everyday recall.

3. Exercise Regularly to Support Brain Health

Regular physical activity supports cardiovascular health, circulation and overall cognitive well-being.

Research suggests that physical activity can positively influence memory, thinking skills and executive function. Exercise can also support emotional well-being by helping manage stress and symptoms of anxiety and depression.

Activities to include in your routine:

• Walking for approximately 30 minutes most days.
• Swimming or cycling.
• Practising yoga or stretching.
• Dancing or participating in recreational sports.

For adults, general physical activity guidelines recommend at least 150 minutes of moderate-intensity aerobic activity per week, alongside muscle-strengthening activities.

Choose activities that suit your fitness level and medical needs. Consistency is more important than intensity.

4. Eat a Balanced Diet to Support Memory and Cognitive Function

A balanced diet provides essential nutrients that support normal brain function and overall health. Nutritional deficiencies, particularly vitamin B12 deficiency, may contribute to memory-related symptoms.

Include a variety of nutrient-rich foods in your daily meals:

A balanced eating pattern containing fruits, vegetables, whole grains, healthy fats and adequate protein supports general health and brain function.

However, no individual food or supplement can guarantee improved memory or prevent cognitive decline. Consult a healthcare professional before taking supplements, particularly if you suspect a nutritional deficiency.

5. Challenge Your Brain Through Mental Stimulation and Active Recall

Mental stimulation provides opportunities to practise learning, problem-solving and remembering information. Regularly engaging in meaningful activities can help maintain cognitive skills.

Consider incorporating these activities into your daily routine:

• Read books and explore unfamiliar subjects.
• Play chess, puzzles or word games.
• Learn a musical instrument or a new language.
• Participate in meaningful conversations.
• Practise remembering information without looking at your notes.

One particularly useful learning technique is spaced retrieval. It involves recalling information at gradually increasing intervals instead of trying to memorise everything in one session.

For example, review newly learned information after a few hours, the following day and again several days later.

Combining spaced practice with active recall can strengthen learning and make information easier to retrieve over time.

How Does the Brain Store and Retrieve Memories?

Memory depends on communication between several interconnected brain regions.

• Hippocampus: Plays an important role in forming new memories.
• Cerebral cortex: Different areas contribute to storing and processing information.
• Prefrontal cortex: Supports working memory, attention and organisation.

Communication between neurons helps establish and strengthen connections involved in learning. The brain’s ability to adapt and reorganise these connections is called neuroplasticity.

Sleep, physical activity, repeated learning and meaningful mental engagement support cognitive health. However, no single lifestyle habit guarantees protection against memory disorders.

When Should You Worry About Memory Problems?

Occasional forgetfulness is generally normal. However, persistent, progressive memory difficulties that interfere with everyday independence deserve professional attention.

Warning signs may include:

• Frequently asking the same questions.
• Getting lost in familiar places.
• Struggling to follow familiar instructions.
• Repeatedly forgetting important appointments.
• Experiencing increasing confusion about time or familiar people.
• Finding everyday tasks increasingly difficult.

These symptoms do not automatically indicate dementia. Memory problems can have several possible causes, including sleep disturbances, medication effects, nutritional deficiencies and psychological concerns.

When Should You Seek Professional Help for Memory Problems?

Consider seeking professional help if memory difficulties persist, worsen or begin affecting your work, relationships or everyday activities.

A healthcare professional can review your symptoms, medical history, sleep patterns, emotional well-being and medications to identify possible contributing factors.

Depending on your symptoms, an assessment may include:

• Cognitive and memory screening.
• Evaluation of stress, anxiety and depression.
• Reviewing medications and sleep-related concerns.
• Checking for nutritional deficiencies or other medical conditions.
• Referral to an appropriate specialist when necessary.

Early assessment can help identify potentially treatable causes and determine appropriate support.

Important: If memory loss or confusion develops suddenly, particularly alongside weakness, speech difficulties or other neurological symptoms, seek emergency medical attention.

Build Healthy Habits for Better Memory

Improving memory involves more than memorising information. Quality sleep, regular physical activity, balanced nutrition, effective learning techniques and emotional well-being all contribute to healthy cognitive function.

Small, consistent lifestyle changes can support better recall and concentration. However, persistent or worsening memory difficulties should never be ignored.

At Insight Psychology, understanding the connection between psychological well-being and cognitive health is important in supporting individuals experiencing memory and concentration difficulties. Seeking professional guidance can help identify underlying concerns and determine appropriate support.
