Sleep is critical for the brain and cognitive function. The effects of sleep loss on the brain and cognition can range from short-term detriments, such as impaired alertness, vigilance, attention, and concentration abilities, to long-term problems, including a higher risk of cognitive decline and dementia. While the function of sleep is not yet fully understood, it is known that a lack of sleep can affect memory consolidation and emotional processing, and can impair numerous cognitive processes, such as language, reasoning, decision-making, learning, and memory. The good news is that there are ways to improve sleep quality and duration, and consequently, restore cognitive function.

What You'll Learn
Seek medical advice and behavioural therapy
Seeking medical advice and behavioural therapy is a crucial step towards improving cognitive function and sleep quality. Here are some detailed instructions and suggestions to consider:
Consult a Doctor or Sleep Specialist
Consider booking an appointment with your doctor or a sleep specialist. They can help diagnose any underlying causes of your sleep troubles and propose tailored solutions, including behavioural therapy or, if necessary, drug treatments. Sleep specialists are particularly trained to identify and address sleep-related issues, so don't hesitate to seek their expertise.
Cognitive Behavioural Therapy for Insomnia (CBT-I)
Cognitive Behavioural Therapy for Insomnia (CBT-I) is a proven and recommended treatment for insomnia. It typically involves 4 to 8 sessions, depending on individual needs, and can be conducted weekly or bi-weekly. CBT-I focuses on identifying and changing unhelpful thoughts and behaviours that contribute to sleep problems. It also involves learning about sleep and insomnia, including the factors that make insomnia different from other sleep issues. While CBT-I may not yield immediate results, its benefits are long-lasting. It has been shown to improve insomnia symptoms in up to 80% of patients, and many also reduce or stop their reliance on sleep medications. CBT-I is also beneficial for those without insomnia but who experience difficulty sleeping, as well as those with mental health issues such as depression, anxiety, and post-traumatic stress disorder.
Self-Help Guides and Resources
Various organisations, including the NHS, offer self-help guides and resources that can be extremely useful. These guides often incorporate elements of cognitive behavioural therapy and expert advice to help manage sleep problems effectively. They can be especially helpful for individuals with mild-to-moderate mental health issues. Additionally, there are guides tailored to specific concerns, such as anxiety, stress, low mood, and depression. These resources can provide actionable steps and strategies to improve your sleep and overall mental wellbeing.
Create a Consistent Daily Routine
Establishing a consistent daily routine can significantly improve your sleep. This includes maintaining a regular sleep schedule by going to bed and waking up at the same time each day. Exposure to natural light in the morning can help signal to your brain that it's time to wake up. Similarly, reducing exposure to light in the evening can prepare your body for sleep. Creating a calming bedtime routine and optimising your sleep environment by minimising noise and light can also promote better sleep.
Practice Good Sleep Hygiene
Good sleep hygiene involves practices such as using your bed only for sleep and sex, avoiding stimulating activities or devices before bed, and refraining from consuming caffeine or foods that cause heartburn close to bedtime. These simple yet effective measures can improve your sleep quality and, consequently, enhance your cognitive function.

Cut out caffeine and foods that cause heartburn
Sleep is critical for the brain, and a lack of sleep can have a detrimental impact on your cognitive functions. While you may not be able to get a full night's rest, there are ways to improve your sleep quality and recover your cognitive function. One way to do this is by cutting out caffeine and foods that cause heartburn.
Caffeine is known to boost acid in the stomach, which can lead to acid reflux or heartburn. This can cause a burning discomfort in your chest or throat. Caffeine can also affect your sleep, especially if consumed late in the day. It is a stimulant that can keep you awake and interfere with your sleep schedule. Therefore, it is advisable to cut down on caffeine or switch to decaffeinated drinks.
Some common foods and drinks that can cause or worsen heartburn include spicy foods, pepper, hot sauces, garlic, onions, peppermint, chocolate, and fatty foods. These foods can irritate the oesophagus and trigger acid reflux. The amount of food consumed can also play a role in heartburn. Overeating can put pressure on the oesophageal sphincter, causing it to relax and allowing stomach acid to escape. Therefore, it is recommended to eat smaller portions and avoid a stuffed stomach to prevent heartburn.
In addition to portion control, the timing of meals is also important. It is advised to allow sufficient time between dinner and bedtime, ideally at least three hours. This gives your body time to digest the food properly and reduces the risk of heartburn interfering with your sleep.
If you experience frequent heartburn, it is recommended to consult a doctor or a gastroenterologist. They can help identify any underlying causes and suggest lifestyle changes or medications to manage your symptoms effectively.

Exercise earlier in the day
Exercise is a great way to improve cognitive function, especially when done earlier in the day. While the mechanism by which physical activity improves sleep is not fully understood, it is known that it does help you fall asleep more quickly and improves sleep quality. Moderate aerobic exercise, in particular, increases the amount of slow-wave sleep you get, which refers to deep sleep when the brain and body rejuvenate.
Exercising earlier in the day can help improve your sleep and, consequently, your cognitive function. This is because exercise can help stabilize your mood and decompress the mind, which is an important cognitive process for transitioning to sleep. It is suggested that at least 30 minutes of moderate aerobic exercise may improve sleep quality that same night. Some examples of moderate-intensity exercises include brisk walking, swimming, stair climbing, tennis, squash, and dancing. Even household activities such as intense floor mopping or raking leaves can be considered moderate-intensity exercises.
It is important to note that the time of day one chooses to exercise may vary from person to person. While some may prefer exercising earlier in the day, others may find that the time of day does not make a difference to their sleep quality. It is recommended that individuals listen to their bodies and choose a workout time that suits them best.
Additionally, it is suggested that establishing exercise as a habit can help improve cognitive function. It is recommended to aim for a goal of exercising at a moderate intensity for 150 minutes per week. This can be achieved by starting with a few minutes a day and gradually increasing the duration by five to ten minutes each week until the goal is reached. It is important to be patient, as it may take about six months to start seeing the cognitive benefits of exercise.

Improve your sleep hygiene
Sleep is critical for the brain and cognitive function. Lack of sleep can cause short- and long-term cognitive impairment, affecting your thinking, memory, attention, alertness, judgment, decision-making, and overall cognitive abilities.
Maintain a Regular Sleep Schedule
Try to go to bed and wake up at the same time every day, even on weekends and vacations. This strengthens your sleep cycles and helps you fall asleep more easily at night. A consistent sleep schedule also helps to regulate your body's internal clock, making it easier to fall asleep and wake up feeling refreshed.
Create a Relaxing Bedtime Routine
Establish a calming bedtime routine to signal to your body and mind that it's time to wind down. This could include activities such as reading, taking a hot bath, listening to soothing music, or practising relaxation techniques like deep breathing or meditation. Start your bedtime routine 1-3 hours before your desired bedtime to give yourself enough time to relax and prepare for sleep.
Make Your Bedroom a Sleep Sanctuary
Transform your bedroom into a peaceful and technology-free zone. Keep the room dark, cool, and quiet. Use earplugs, white noise, or soundproofing if necessary to minimise noise distractions. Reserve your bed only for sleeping and intimate activities. Avoid watching TV, working, or browsing the internet in bed, as these activities can stimulate your mind and make it harder to fall asleep.
Avoid Substances That Interfere with Sleep
Caffeine and alcohol can disrupt your sleep, even if you feel they don't affect you. Avoid consuming caffeinated beverages in the evening, and limit your alcohol intake before bedtime. While alcohol may help you fall asleep initially, it often leads to fragmented and restless sleep throughout the night.
Exercise Regularly, But Not Too Close to Bedtime
Engaging in regular physical activity can improve your sleep quality, but it's important to time your workouts wisely. Aim to exercise earlier in the day or at least 3-4 hours before bedtime. Exercising too close to bedtime may increase alertness and make it more challenging to fall asleep.
