Reset Your Sleep Cycle With These 5 Simple Steps

Reset Your Sleep Cycle With These 5 Simple Steps

Do you ever find yourself tossing and turning all night, desperately seeking that elusive, deep slumber that seems out of reach? If so, you may be struggling with a disrupted sleep cycle. But a healthy sleep schedule is not just a luxury—it's a necessary component of a healthy lifestyle. Just like a balanced diet or regular exercise, maintaining a steady sleep cycle plays a crucial role in our overall well-being. Its importance goes beyond banishing under-eye shadows or boosting energy. The right amount of quality sleep affects everything, from your mood, productivity and cognitive functions, to more hidden processes like healing and repairing your heart and blood vessels. 

Understanding Your Sleep Cycle

First and foremost, what is a sleep cycle? In its simplest form, a sleep cycle refers to the pattern of sleep stages that your brain goes through in approximately 90-minute cycles throughout the night. Following a regular sleep cycle is vital for your overall health and cognitive functioning. However, disruptions like stress, jet lag, or poor sleep habits can throw your sleep cycle off balance. 

Your sleep cycle consists of four different stages of sleep: stage 1, stage 2, deep sleep (stages 3 and 4), and REM (rapid eye movement) sleep. The cycle progresses as follows:

  • Stage 1 Dozing Off (5-10 minutes): This is the transition phase between wakefulness and sleep. It’s a short period of relatively light sleep that lasts for about 5 to 10 minutes. 
  • Stage 2 Light Sleep (10-60 minutes): Your body starts to slow down – your heart rate and breathing ease up, and your muscles relax further. Think of it as getting comfortable before the deep stuff begins.
  • Deep Sleep (Stages 3 & 4 - 20-40 minutes): This is where the magic happens. Your body goes into deep restoration mode, repairing tissues, strengthening your immune system, and refilling your energy tank. If someone were to try and wake you, they'd have a tough time! 
  • REM Sleep (10-60 minutes): Brain activity ramps up during this stage, and that's when you experience those vivid dreams. It's like a cognitive power-up, consolidating memories and learning. 

The circadian rhythm, your internal body clock, plays a crucial role in regulating your sleep-wake cycle by influencing when you feel tired and alert. It follows a 24-hour cycle that relies heavily on external factors such as light and darkness. When it gets dark, your body produces the hormone melatonin, which induces sleep, and when the sun rises, it decreases melatonin production, promoting wakefulness.

The Domino Effect of a Disrupted Sleep Cycle

When your sleep cycle takes a nosedive, the consequences ripple far beyond mere sleepiness. It's a domino effect that can topple your entire well-being.

On the physical front, disrupted sleep can lead to chronic fatigue, making even the simplest tasks feel arduous. You might find yourself hit with waves of exhaustion in the middle of the day or unable to mobilise the energy required for your routine tasks. This is because sleep plays a vital role in our body's recovery process; it's the time our cells regenerate and our bodies recharge. 

Beyond fatigue, imbalances in your rest routine can weaken your immunity. With a compromised immune system, we become more susceptible to infections, with colds, flu, and other illnesses able to take hold more easily. So, if you're noticing an unusual uptick in the frequency of catching colds, it might be due to a disturbed sleep cycle. 

But it's not just our physical health that can suffer. Mental health can also be affected. Anxiety and depression, for instance, are often associated with disrupted sleep. This makes sense when you consider that restful sleep provides the brain with a crucial opportunity to process emotions and maintain psychological balance. Missing out on this essential activity can leave us feeling overwhelmingly low, exceptionally nervous, or strikingly irritable. 

Reset Your Sleep Cycle With These 5 Simple Steps

Step 1: Become a Creature of Habit

Your body craves regularity, and your sleep-wake cycle is no exception. When you go to bed and wake up at the same time every day, your body's internal clock, or circadian rhythm, adjusts to these times. This adjustment makes it easier for you to fall asleep and wake up naturally without relying on an alarm clock. 

But why is a consistent sleep schedule so essential? Well, for starters, it helps regulate your body's natural hormone levels. When you have a regular sleep schedule, your body knows when to release hormones like melatonin, which induces sleep. Another hormone, cortisol, helps you feel awake and alert during the day, and its levels naturally decrease at night when you're ready to sleep. 

In addition to hormone regulation, having a consistent sleep schedule can also improve the quality of your sleep. Your body knows what to expect and when to expect it, so it's better prepared to enter the different stages of sleep, including deep, restorative sleep.

Step 2: Balance Light and Dark 

Light plays a critical role in regulating your body's natural sleep-wake cycle. When it's light outside, your body naturally produces less melatonin, a hormone that helps you fall asleep. In contrast, when it's dark outside, your body naturally produces more melatonin, signalling that it's time for sleep. 

To reset your sleep pattern, try to seek out natural light upon waking and limit your exposure to artificial light, especially close to bedtime. Getting natural light exposure in the morning can help regulate your body's internal clock and make it easier for you to fall asleep at night. If you work in an office or don't have access to natural light in the morning, consider investing in a light therapy lamp. These lamps mimic natural sunlight and can help regulate your body's natural rhythms. 

On the flip side, it's essential to limit your exposure to artificial light, especially in the hours leading up to bedtime. Electronic devices like smartphones, tablets, and computers emit blue light, which can suppress the production of melatonin and make it harder to fall asleep. Try to avoid using electronic devices at least an hour before bed. If you must use them, consider using blue light-blocking glasses or enabling night mode on your devices.

You could even consider investing in a dimmable night light for sleep or using an eye mask to block out external lights. 

Step 3: Optimise Your Sleep Environment 

Making a few simple changes to your bedroom can help you achieve more restful and rejuvenating sleep. 

First and foremost, your sleep environment should be dark, quiet, and cool. Darkness helps your body produce melatonin, a hormone that helps you fall asleep. So, if you have any external light sources, like streetlights or car headlights, invest in blackout curtains or shades to block out the light. Also, try to limit noise as much as possible, which can disrupt your sleep. You can invest in earplugs or a white noise machine to help block out noise. 

In addition to darkness and quietness, the temperature of your sleep environment plays a vital role in the quality of your sleep. A cool room, around 60-67 degrees Fahrenheit, is optimal for sleep. Your body temperature naturally drops at night, and a cool room helps facilitate this process, making it easier for you to fall asleep and stay asleep. Another essential factor in optimising your sleep environment is investing in comfortable bedding. Your mattress, pillows, and sheets should be comfortable and supportive. If your mattress is old or uncomfortable, it may be time to invest in a new one. Similarly, your pillows should provide adequate support for your neck and head. Sheets should be soft and comfortable against your skin. 

Lastly, reserve your bed for sleep and intimacy only. Avoid using your bed as a workspace or a place to watch TV, as this can weaken the association between your bed and sleep. By reserving your bed for sleep and intimacy only, you strengthen the connection between your bed and sleep, making it easier for you to fall asleep at night.

Step 4: Be Mindful of What You Eat and Drink 

Ensuring you get the right nutrients can significantly impact the quality of your sleep. While you may not have considered the effect that your dietary consumption has on your sleep pattern, there's a direct link between what you eat and how well you sleep. 

Start with magnesium, often referred to as the 'sleep mineral'. Magnesium helps your body maintain a steady heart rhythm and healthy blood pressure levels. It plays a crucial role in the function of your nervous system, which directly impacts how well you sleep. Lack of magnesium can lead to insomnia and other sleep disorders, so make sure to include foods rich in magnesium in your diet, like nuts, whole grains, and leafy green vegetables. 

The best magnesium supplement I’ve had
"I’ve tried other brands but this one is just fantastic. My sleep is so much better and it’s really helped with my digestion." - Sophie R.
Our high potency and excellent absorption formula contains 1480mg Magnesium Citrate per serving providing you with 440mg of needed Elemental Magnesium.

Next up is tryptophan, a crucial amino acid that helps your body produce serotonin. Serotonin is a neurotransmitter that can improve your mood and promote healthy sleep. You can find tryptophan in foods like chicken, turkey, cheese, nuts, and seeds. 

Helps me to feel relaxed at bedtime
"Really helped me get sleep. Good quality." - Hazel B. 
Our Natural Night Complex has been formulated with carefully selected botanicals and minerals such as calming Lemon Balm and Chamomile, Magnesium, Vitamin B12 and Biotin. You can get this unique blend of soothing ingredients per daily dose (1 capsule).

Lastly, consider adding Vitamin B6 to your nutrient list. Vitamin B6 helps in the production of melatonin, a sleep hormone regulated by light exposure. Foods high in Vitamin B6 include chickpeas, tuna, and bananas. Remember, a healthy diet can result in improved sleep health and ultimately, a more balanced sleep cycle. 

A great product to give energy boost
"Very good for keeping energy levels high. If you suffer from fatigue then go for these." - Rachael Z.

Step 5: Unwind Before You Wind Down 

Finally, a relaxing routine before bed can signal your body that it's time to wind down and go to sleep. 

There are many different activities that you can incorporate into your bedtime ritual. Reading a book, for example, is a great way to unwind and escape into a different world. Choose a book that isn't too stimulating or exciting, as this can have the opposite effect and keep you awake. 

Meditation is another effective technique for promoting relaxation and reducing stress. There are many different types of meditation, so find one that works for you. You can try guided meditations, breathing exercises, or visualisation techniques. 

Taking a warm bath or shower before bed is another excellent way to relax your body and mind. The warm water can help ease tension and promote relaxation, making it easier for you to fall asleep. 

Finally, visualisation techniques can be extremely effective in creating a relaxing scenario and detaching from the day's stresses. Close your eyes and imagine a peaceful and calming scene, like a beach or a forest. Focus on the sights, sounds, and smells of this scene, allowing yourself to completely immerse in it.
