The Ultimate Guide to Better Sleep: Tips, Science and Natural Solutions

05.14.2025

Getting quality sleep is one of the most important things we can do for our health and overall sense of wellbeing — yet so many people struggle with it, whether it’s not getting enough hours or just not sleeping well. At Two Islands, we know that a good night’s rest is one of the three core pillars of feeling your best, right alongside nutrition and movement.

This comprehensive guide will explore the science behind sleep, common challenges, and natural solutions to help you achieve the restorative slumber your body craves.

Why Sleep Matters

Sleep isn't just about resting. It's when our body and brain do important work. Research has shown that adequate sleep is essential for cognitive function, emotional regulation, and physical health. Chronic sleep deprivation has been linked to a host of health issues, including increased risk of cardiovascular disease, weakened immune function, and impaired mental health.

Here’s what happens when we sleep:

• Our brain sorts through memories and learns new things
• Our body repairs itself and fights off sickness
• Our emotions reset, helping us feel better the next day

When we don't get enough sleep, it can cause all sorts of problems. Most adults need between 7 to 9 hours of sleep each night to feel their best.

The Effects of Sleep Deprivation

Not getting enough sleep? You’re not alone, and it happens for all kinds of reasons. Maybe you stayed up too late, woke up too early, or just couldn’t fall asleep. Here's what can happen when you don't get enough sleep:

• You might feel grumpy, sad, or worried
• It's harder to think clearly or remember things
• Your body might have trouble fighting off colds and flu
• You could gain weight more easily
• Your risk of health problems like diabetes and heart disease goes up

Even missing a little sleep can start to take a toll, and it adds up faster than you’d think. When you consistently lose just 30 to 60 minutes of sleep over a few days, your body builds up what’s called “sleep debt.” It’s cumulative, meaning those missed minutes stack up — and your body feels it.

Nearly 60% of New Zealanders say they wake up feeling unrested, which is a clear sign that poor sleep is a widespread issue affecting how we feel and function each day.

Common Sleep Challenges

• Stress and worry keeping your mind busy
• Bad sleep habits, like using your phone right before bed
• Noisy or bright bedrooms
• Eating big meals or drinking alcohol close to bedtime
• Irregular sleep schedules
• Health issues like pain or sleep disorders

Natural Sleep Solutions

At Two Islands, we believe in using nature to help you sleep better. Our Nightcap supplement is a natural herbal elixir designed to promote relaxation and restore good-quality sleep. This synergistic blend contains scientifically researched ingredients that help calm a busy mind and relax the body — aiding both in falling asleep and staying asleep.

Key Ingredients in Nightcap:

• Tart Cherry: Rich in melatonin, tart cherry has been shown to improve sleep duration and quality. They also contain small amounts of tryptophan, an amino acid that acts as a precursor to serotonin — an important neurotransmitter that helps regulate mood and sleep.
• Ashwagandha: This adaptogenic herb helps reduce stress and anxiety, promoting more restful sleep. In an 8-week study, participants who took Ashwagandha fell asleep faster, slept longer overall, and spent less time awake during the night.
• Passionflower: Studies indicate that passionflower can improve sleep quality by increasing GABA levels in the brain. GABA is a neurotransmitter that lowers brain activity, which may help your mind and body relax to facilitate a deeper sleep.
• Saffron: By interacting with neurotransmitters involved in mood regulation, saffron has been shown to enhance sleep quality and duration while reducing the severity of insomnia.

These ingredients work together to help you unwind, fall asleep easier, and stay asleep through the night.

Tips for Better Sleep

In addition to natural supplements like Nightcap, incorporating these science-backed strategies can significantly improve your sleep:

• Stick to a sleep schedule: Try to go to bed and wake up at the same time every day, even on weekends. This helps set your body's internal clock.
• Create a bedtime routine: Do calm things like reading or stretching an hour before bed. This signals to your body that it's time to wind down.
• Make your bedroom sleep-friendly: Keep it dark, quiet, and cool. The best temperature for sleep is usually between 15–19°C. Use curtains, earplugs, or a white noise machine if needed.
• Limit screen time: The blue light from phones and computers can make it harder to fall asleep. Try to stop using them an hour before bed. If you must use them, try blue light blocking glasses or apps that reduce blue light.
• Exercise regularly: Being active during the day can help you sleep better at night. Just don't exercise too close to bedtime, as it might make it harder to fall asleep.
• Watch what you eat and drink: Avoid big meals, caffeine, and alcohol close to bedtime. They can mess with your sleep. If you're hungry, a light snack like a banana or a small handful of nuts is okay.
• Manage stress: Try relaxation techniques like deep breathing, meditation, or gentle yoga to calm your mind before bed.
• Get some sunlight: Spending time outside during the day can help keep your body's sleep pattern on track. Try to get at least 30 minutes of natural light each day.
• Don't lie in bed awake: If you can't fall asleep after 20 minutes, get up and do something calming until you feel sleepy.
• Avoid naps late in the day: If you need a nap, keep it short (15–30 minutes) and before 3 PM.

Understanding Your Sleep Cycle

When we sleep, our body moves through different stages. Each one plays a key role in keeping us healthy and balanced:

• Light sleep: The first stop. It’s that drowsy, in-and-out phase where you can still wake up pretty easily.
• Deep sleep: When your body gets to work repairing and restoring itself. It’s the hardest stage to wake up from — and for good reason.
• REM sleep: Where dreaming happens. This stage supports brain function, especially learning, memory, and emotional processing.

A solid night’s sleep includes several cycles through all of these stages, with each full cycle lasting about 90 minutes. The better your body can move through them, the more rested and restored you’ll feel in the morning.

The Link Between Sleep and Mental Health

Sleep and mental health are closely connected. Poor sleep can lead to mental health issues, and mental health problems can make it harder to sleep well. Here's how they're linked:

• Lack of sleep can increase anxiety and depression
• Good sleep can help you manage stress better
• Sleep problems are common in many mental health conditions
• Improving your sleep can often help improve your mental health

When to Seek Help

If you've tried these tips and still have trouble sleeping, it might be time to talk to a doctor. Some signs you might need help include:

• Taking more than 30 minutes to fall asleep most nights
• Waking up often during the night and having trouble getting back to sleep
• Feeling very tired during the day
• Loud snoring or stopping breathing during sleep (which could be sleep apnea)

Remember, good sleep is a key part of a healthy life. It's just as important as eating well and exercising. By understanding how sleep works and making some simple changes, you can improve your sleep and feel better every day.

By understanding the science of sleep, addressing common challenges, and incorporating natural solutions like Two Islands Nightcap, you can take significant steps toward better sleep and improved overall health.
