Battling Insomnia: Awake But Longing For Sleep

Feeling tired but unable to sleep is a common problem with a variety of causes. These include lifestyle habits, medications, or physical or mental health conditions. For example, daytime napping, anxiety, and the use of electronic devices before bed can all contribute to difficulty falling asleep. Additionally, factors such as chronic pain, jet lag, and certain medications can also play a role. Addressing these underlying causes and practicing good sleep hygiene can help improve sleep quality. This includes maintaining a consistent sleep schedule, optimizing the bedroom environment, and reducing caffeine and alcohol consumption close to bedtime.

Avoid caffeine, especially close to bedtime

Caffeine is a stimulant that can significantly impact your sleep, even if consumed several hours before bedtime. Caffeine blocks adenosine, a chemical that gradually accumulates in the brain as you stay awake, making you feel sleepier. This effect can last up to six hours, reducing sleepiness and contributing to difficulty falling or staying asleep.

To avoid the negative impact of caffeine on your sleep, it is recommended to stop consuming caffeinated beverages at least four to six hours before bedtime. This includes coffee, soda, tea, energy drinks, and even chocolate. Some people who are especially sensitive to caffeine may need to stop consuming it earlier in the day or avoid it altogether. If you're struggling to fall asleep, gradually move your last caffeinated drink earlier in the day and observe how it affects your sleep.

It's important to note that individual factors, such as your adenosine levels, ability to clear caffeine, and tendency towards insomnia, can influence how caffeine affects your sleep. Additionally, the effects of caffeine on sleep may vary depending on the time of day it is consumed and individual differences in caffeine sensitivity, absorption, and metabolism.

If you find that reducing your caffeine intake doesn't improve your sleep, consider consulting a sleep specialist to explore other factors that may be contributing to your sleep difficulties.

Limit screen time before bed

Screen time before bed can have a detrimental effect on the quality of your sleep. Here are four reasons why you should limit screen time before bed:

Screen Light Disrupts Circadian Rhythm

The circadian rhythm is your body's natural clock. Light exposure dictates when you are awake and alert. During the day, when it is light, your body suppresses the production of melatonin, the hormone that helps you fall asleep and stay asleep. At night, when it is dark, your body produces more melatonin, with levels peaking between 2 and 4 am. However, the blue light emitted by phones, laptops, and TV screens imitates daylight, tricking your brain into producing less melatonin. As a result, you will remain awake and alert at night, and your body's natural sleep cycle will be disrupted.

Radiation Exposure

Cell phones emit low levels of radiation, which can cause sleep delays and reduce sleep quality. Radiation exposure from phones can also cause headaches and confusion. Furthermore, the blue light emitted by screens can cause damage to the retina, as studies on animals have shown.

Emotional Stimulation

Social media and other online content can evoke strong emotions, which can make it difficult to fall asleep. Lack of sleep can then lead to decreased mental function and irritability, leaving you feeling groggy and tired the next morning.

Lack of Wind-Down Time

Screen time before bed does not allow your mind and body to rest and prepare for sleep. It is important to create a bedtime routine that is completely screen-free, giving yourself at least 30 minutes away from the distractions and stimulation of technology.

• Use Nighttime mode or dim the brightness of your phone
• Make your bedroom a screen-free zone
• Keep the lighting dim a couple of hours before bed
• Create a bedtime routine that does not involve screens
• Read a book before bed instead

Try breathing exercises

Breathing exercises can help you relax and sleep better. Here are some techniques to try:

4-7-8 breathing technique

• Part your lips gently.
• Exhale completely, making a breathy whooshing sound.
• Press your lips together and silently inhale through your nose for a count of 4 seconds.
• Hold your breath for a count of 7 seconds.
• Exhale again for a full 8 seconds, making a whooshing sound.
• Repeat the cycle 4 times when you first start. Gradually work up to 8 repetitions.

Bhramari pranayama breathing exercise

• Close your eyes and breathe deeply in and out.
• Cover your ears with your hands.
• Place each index finger above your eyebrows and the rest of your fingers over your eyes.
• Put gentle pressure on the sides of your nose and focus on your brow area.
• Keep your mouth closed and breathe out slowly through your nose, making a humming "Om" sound.
• Repeat the process 5 times.

Three-part breathing exercise

• Take a long, deep inhale.
• Exhale fully while focusing intently on your body and how it feels.
• After doing this a few times, slow down your exhale so that it's twice as long as your inhale.

Diaphragmatic breathing exercise

• Lie on your back with your knees bent over a pillow or sit in a chair.
• Place one hand flat against your chest and the other on your stomach.
• Take slow, deep breaths through your nose, keeping the hand on your chest still as the hand on your stomach rises and falls with your breaths.
• Breathe slowly through pursed lips.
• Eventually, aim to breathe in and out without your chest moving.

Alternate nasal breathing exercise

• Sit with your legs crossed.
• Place your left hand on your knee and your right thumb against your nose.
• Exhale fully and then close your right nostril.
• Inhale through your left nostril.
• Open your right nostril and exhale through it while closing your left.
• Continue this rotation for 5 minutes, finishing by exhaling through your left nostril.

Buteyko breathing

• Sit in bed with your mouth gently closed and breathe through your nose at a natural pace for about 30 seconds.
• Breathe a bit more intentionally in and out through your nose once.
• Gently pinch your nose closed with your thumb and forefinger, keeping your mouth closed, until you feel that you need to take a breath again.
• With your mouth still closed, take a deep breath in and out through your nose again.

The Papworth method

• Sit up straight, perhaps in bed, if using this to fall asleep.
• Take deep, methodical breaths in and out, counting to 4 with each inhale and exhale. Inhale through your mouth or nose, and exhale through your nose.
• Focus on your abdomen rising and falling, and listen for your breath sounds to come from your stomach.

Box breathing

• Sit with your back straight, breathe in, and then try to push all the air out of your lungs as you exhale.
• Inhale slowly through your nose and count to 4 in your head, filling your lungs with more air with each number.
• Hold your breath and count to 4 in your head.
• Slowly exhale through your mouth, focusing on getting all the oxygen out of your lungs.

Make a to-do list

If you're tired but can't sleep, it might be a good idea to make a to-do list. Research has shown that writing out a long, detailed to-do list of future tasks can help people fall asleep faster than those who wrote about tasks they had already accomplished that day.

• Write down all your pending tasks, no matter how big or small. Be as detailed as possible, including deadlines, subtasks, and reminders.
• Prioritize the tasks based on their urgency and importance. You can use a simple numbering or bullet system to indicate their priority.
• Keep the list easily accessible, preferably on paper by your bedside. This way, you can add tasks as they come to mind without having to get out of bed and turn on a device.
• Update the list regularly, crossing out completed tasks and adding new ones. This will help you stay organized and ensure that your to-do list doesn't become overwhelming.
• If you prefer digital tools, there are many apps and software programs that can help you create and manage your to-do lists. These often offer features such as reminders, categorizations, and even collaboration if you need to share tasks with others.
• Consider setting aside a specific time each day to review and update your to-do list. This can help you stay organized and ensure that you don't forget any important tasks.
• If you find that your to-do list is causing you more stress or anxiety, try adjusting the format or the level of detail. For example, you could try breaking down large tasks into smaller, more manageable steps.

Remember, the goal of making a to-do list is to help calm your mind and reduce any stress or anxiety related to your pending tasks. By writing down your tasks and organizing them, you can free up mental space and hopefully drift off to sleep more easily.

Avoid heavy meals close to bedtime

If you're struggling to fall asleep, it's best to avoid eating heavy meals close to bedtime. Eating late at night goes against your body's circadian rhythm and can negatively impact your sleep. Here are some reasons why you should avoid heavy meals before bed:

Impact on Circadian Rhythm

Your body's circadian rhythm is an internal timekeeper that regulates various functions, including metabolism, body temperature, and hormone production, over a 24-hour period. Eating late at night disrupts this rhythm, particularly affecting your insulin sensitivity. Your body is more insulin-sensitive in the morning to help fuel your daily activities. However, insulin resistance increases at night, leading to the storage of extra calories as fat while you sleep instead of being burned throughout the day. This disruption can impact your weight and overall health.

Difficult Digestion

Heavy meals consumed close to bedtime can also lead to indigestion and discomfort. Fatty, cheesy, and fried foods are difficult to digest and may keep you up at night. Opting for lighter, healthier options can improve your sleep quality.

Unhealthy Choices

Late-night eating often involves making less healthy food choices. We tend to crave and consume unhealthy snacks, such as chips, cookies, and ice cream, as part of our nighttime relaxation routine. These choices can be high in fat, sugar, and calories, contributing to weight gain and disrupting sleep.

Acid Reflux

Eating close to bedtime can also trigger acid reflux, especially if you lie down soon after eating. This occurs when stomach acid splashes back into your throat, causing symptoms like heartburn, difficulty swallowing, and a lump in the throat. Avoiding late-night meals and trigger foods can help prevent these symptoms and improve your sleep quality.

Weight Gain

Research suggests a link between bedtime snacking and weight gain. Eating before bed can be an extra meal, adding more calories to your daily intake. Additionally, the evening is when some people feel hungriest, and stress can increase the hunger hormone, leading to overeating. Creating a cycle of overeating and weight gain, it's best to eat balanced meals during the day and avoid excessive snacking at night.

In summary, avoiding heavy meals close to bedtime is essential for maintaining a healthy sleep schedule and overall well-being. It helps to respect your body's circadian rhythm, aids digestion, and prevents unhealthy eating habits that can disrupt sleep and contribute to weight gain.
