Sleep is essential for the brain and body to function optimally. While the amount of sleep required varies from person to person, most healthy adults need seven to nine hours of sleep. However, with busy schedules, some may aim to train their bodies to function on less sleep. While long-term sleep deprivation is detrimental, it may be possible to gradually reduce sleep by improving sleep quality and adopting strategies like napping, sleep banking, and creating bedtime rituals. Additionally, genetics play a role, with some people naturally needing less sleep due to the hDEC2 gene mutation.

What You'll Learn
Set a consistent sleep and wake-up time
Setting a consistent sleep and wake-up time is crucial for training your body to use less sleep effectively. Here are some detailed tips to help you establish a consistent sleep schedule:
Firstly, it is important to understand that everyone's sleep needs vary based on factors like age and genetics. While some people are genetically predisposed to be "short sleepers," requiring only 4 to 6 hours of sleep, others are long sleepers, feeling their best with 9 or more hours of sleep. Most healthy adults should aim for 7 to 9 hours of sleep each night.
To set a consistent sleep schedule, start by choosing a bedtime and wake-up time that aligns with your natural sleep needs. Stick to these times every day, including weekends. Maintaining a consistent wake-up time is particularly important, as it trains your body to develop a regular sleep rhythm. You can gradually adjust your bedtime if needed, but ensuring you wake up at the same time each day is key.
Create a bedtime ritual or routine to signal to your body that it's time to wind down and prepare for sleep. This could include activities such as reading a book, listening to soothing music, or practising relaxation techniques like deep breathing or meditation.
Optimise your bedroom environment to make it sleep-friendly. Ensure your bedroom is comfortable, dark, and quiet. Consider investing in blackout curtains, earplugs, or a white noise machine if necessary. Additionally, maintain a comfortable temperature in your bedroom, neither too hot nor too cold.
Limit your exposure to screens and bright lights before bed. The blue light emitted by smartphones, laptops, and other electronic devices can interfere with your sleep hormones and make it difficult to fall asleep. Instead, opt for relaxing activities that don't involve screens, especially in the hours leading up to your bedtime.
By setting a consistent sleep and wake-up time and creating a supportive sleep environment, you can effectively train your body to function optimally with less sleep. However, it's important to listen to your body and ensure you're getting sufficient rest to maintain your overall health and well-being.

Gradually reduce sleep by 20 minutes each week
While it is not advisable to get less sleep than your body needs, it is possible to train your body to use less sleep. However, it is important to note that long-term sleep deprivation can have adverse effects, including reduced concentration, confusion, and an increased risk of obesity, diabetes, high blood pressure, and cardiovascular disease.
If you are looking to gradually reduce your sleep by 20 minutes each week, here are some detailed instructions to help you achieve that goal:
Set a consistent wake-up time
No matter what day of the week it is, ensure you wake up at the same time every day. This helps to regulate your body's sleep-wake cycle and is a crucial step in establishing a new sleep routine.
Gradually adjust your bedtime
For the first week, go to bed 20 minutes later than your usual bedtime. In the following weeks, continue to adjust your bedtime by 20 minutes increments until you reach your desired sleep duration.
Exercise regularly
Engage in physical exercise 3-4 times a week. This will help improve your strength and stamina, making it easier for your body to handle reduced sleep.
Optimize your sleep environment
Ensure your bedroom is comfortable, dark, and quiet. A high-quality sleep environment will help you make the most of the sleep you get, reducing the negative impacts of a reduced sleep schedule.
Develop a bedtime ritual
Engage in relaxing activities before bed, such as reading a book or doing a crossword puzzle. This signals to your body that it's time to wind down and prepares it for sleep.
Avoid stimulants and blue light before bed
Nicotine, caffeine, and blue light from electronic devices can interfere with your sleep. Avoid these stimulants and bright lights in the hours leading up to your bedtime to improve your sleep quality.
Remember, it is essential to listen to your body and prioritize your health. If you experience negative effects from reducing your sleep, consider consulting a healthcare professional for personalized advice.

Exercise regularly to build stamina
While it is possible to train your body to use less sleep, it is important to note that sleep is vital for the brain and body to function optimally. When you sleep less, your cognitive performance and reaction times may be affected.
Exercising regularly is a great way to build stamina and improve your sleep quality. Working out is beneficial for both your body and mind, and it can help you get a good night's sleep. However, it is important to listen to your body and understand how exercise affects your sleep. For some people, exercising too late in the day can interfere with sleep.
- Moderate-to-vigorous exercise: Engage in moderate-to-vigorous aerobic exercise to increase sleep quality, reduce the time it takes to fall asleep, and decrease the time spent lying awake. Examples include power lifting and active yoga classes, which elevate your heart rate and create beneficial biological processes in the brain and body.
- Timing of exercise: Be mindful of the timing of your workouts. While some people can exercise at any time of day without affecting their sleep, others may need to avoid vigorous physical activity at least one to two hours before bedtime. Listen to your body and adjust the timing of your workouts accordingly.
- Consistency: Consistency is key when it comes to exercise. Aim for at least 30 minutes of moderate aerobic exercise daily to see improvements in your sleep quality. You don't need to train for a marathon; even moderate exercise can have a positive impact on your sleep.
- Exercise preference: Pick an exercise that you enjoy and are likely to stick with. This could be power lifting, yoga, running, swimming, or any activity that elevates your heart rate. The most important thing is to find an exercise routine that you can consistently maintain.
- Stabilize your mood: Exercise can help stabilize your mood and decompress your mind, making it easier to transition to sleep. This is especially beneficial if you experience stress or anxiety that interferes with your sleep.
- Create a bedtime routine: In addition to exercise, establish a relaxing bedtime routine to improve your sleep quality. This can include dimming the lights, turning off electronic devices, and engaging in relaxing activities like reading or listening to soothing music.

Avoid nicotine and other stimulants
While it is possible to train your body to use less sleep, it is important to note that this strategy may not work for everyone. Sleep is essential for cognitive performance and overall health, and chronic sleep deprivation can lead to adverse effects.
Nicotine is a stimulant that can disrupt your sleep. Smoking cigarettes throughout the day can lead to trouble sleeping at night. In addition, tobacco weakens your body and immune system, which may result in requiring more sleep to recover. Quitting smoking can help improve your sleep quality and overall health.
Other stimulants, such as caffeine, can also impact your sleep. Consuming caffeine in the afternoon or evening can stimulate your brain when it should be winding down, making it difficult to fall asleep. It is best to avoid caffeine after lunch if you want to train your body to use less sleep.
Additionally, artificial blue light from smartphones, laptops, and other screens can inhibit the release of melatonin, a crucial hormone for inducing sleep. It is recommended to avoid screens for at least two hours before bedtime to improve your sleep quality.
By avoiding nicotine, caffeine, and excessive screen time before bed, you can improve your sleep habits and train your body to function optimally with less sleep. However, it is important to prioritize sleep and ensure you are getting adequate rest to maintain your overall health and well-being.

Establish a bedtime ritual to relax
Establishing a bedtime ritual to relax is an important step in training your body to use less sleep. A bedtime ritual is a routine performed before going to bed, consisting of one or more relaxing activities that help you prepare for sleep. Here are some tips to create an effective bedtime ritual:
Choose Relaxing Activities
Select activities that help you unwind and relax mentally and physically. This could include deep breathing exercises, progressive muscle relaxation, or simple stretches to release physical tension. Meditation and mindfulness practices can also help manage emotions and reduce stress, improving sleep quality.
Create a Consistent Routine
Consistency is key when establishing a bedtime ritual. Try to perform your chosen activities in the same order every night. This helps train your brain to associate the ritual with sleep. Your ritual can be simple, such as washing your face, brushing your teeth, and changing into pajamas. Or it can be more elaborate, like adding a warm bath, a walk, or drinking herbal tea.
Set a Schedule
Schedule a specific time to begin your bedtime routine each night, ideally 30 minutes to 2 hours before bedtime. Consistency in the timing of your ritual helps align your activities with your natural sleep-wake cycle. Use a reminder alarm if needed to stick to your schedule.
Avoid Screen Time
Avoid watching television, using computers, or browsing social media close to bedtime. The blue light emitted by electronic devices tricks your brain into thinking it is daytime, disrupting your sleep. Instead, opt for reading a book or listening to soothing music or nature sounds to relax and prepare for sleep.
Maintain a Sleep-Conducive Environment
Ensure your bedroom is neat and tidy. A cluttered room can induce a sense of chaos and restlessness. Adjust your bedroom environment to promote relaxation, such as dimming the lights and maintaining a cool temperature of around 65 degrees Fahrenheit.
Remember, the key to a successful bedtime ritual is finding what works best for you. Experiment with different activities and create a personalized ritual that helps you relax and prepare for a restful sleep.
