Many sleep issues can be resolved by simply improving your sleep hygiene and while some disorders may require more specialist intervention and treatment, you can often resolve your own complaints simply by making positive and consistent changes to your pre-bedtime behaviour.

How can you practice good sleep hygiene?

1. Create a sleep routine

Waking up at the same time each morning and then going to sleep at the same time each night will help to keep your circadian rhythm in balance, promoting better, more consistent sleep. But don't just do it during the week. Try and do it at weekends too, even if it is tempting to stay up late and then have a lie in.

"Our internal clock is quite sensitive to changes, and even one or two days of sleeping in late can make it harder to fall asleep the following night," explains Graham. "Try and avoid afternoon naps too, as these can delay bedtime and further confuse your sleep schedule."

What's a sleep recovery room and how can you transform your bedroom into one

  What's a sleep recovery room and how can you transform your bedroom into one Senior Director of Sleep Experience & Technology for Tuft & Needle JD Velilla gets candid about optimizing your bedroom for your best sleep everAs a self-proclaimed sleep nerd and even sleep hacker, Velilla coined the idea of the sleep recovery room to emphasize the importance of prioritizing your space as one that benefits sleep and active recovery.  It's all about identifying and curbing the distractions in your environment that keep you from getting a good night's sleep.

2. Set the right sleep environment

Ensure your bedroom is as dark as possible. If you have curtains or blinds that still allow some light in, try using a blackout eye mask. A cool room, but not a cold one, is the temperature to aim for – somewhere between 15-19 degrees Celsius – and invest in the best duvet for ultimate comfort.

3. Eliminate stress

It's sometimes easier said than done, but tackling those issues that cause stress and anxiety in your life can play a vital part in helping you to sleep better. When you're stressed, your levels of the hormone cortisol increase and that acts to suppress melatonin, the hormone that promotes and moderates your sleep. So it's vital you take steps to de-stress. Whether that's going for a walk, talking with friends and family or getting lost in a book – do something that really takes your mind off other matters.

"Yoga nidra and sleep meditation exercises are also great ways to end your day and ease into sleep," adds Graham.

4. Get active

As well as being one of the most effective things to tackle stress, exercise is imperative if you want to improve your sleep because it encourages the body to shut down and recover properly. Be wary of when you do it, though. "Aim for morning or afternoon exercise, but avoid strenuous exercise within 2-3 hours of bedtime, as this can make it harder to fall asleep," says Graham.

5. Avoid caffeine

That 4pm cup of coffee might be just the ticket for a little pick me up during the day, but it can play havoc with your sleep, especially if you have it later in the day. "It can take 10-12 hours for caffeine to fully leave your system so try and limit your caffeine consumption to the morning only," says Graham.

Similarly, avoid other stimulants like alcohol and nicotine within two hours or bedtime – they can be just as troublesome when you're trying to drift off.

6. Shut down those screens

Electronic devices like mobile phones, tablets and laptops all emit blue light through their screens, which our brain can perceive as being similar to sunlight. As it gets darker, our brains naturally produce melatonin to help promote sleep. Evening exposure to blue light can interfere with melatonin release, tricking our brains into thinking we should still be awake. "So if you need to use a screen after sunset, use a night filter or invest in a pair of blue-blocking glasses," advises Graham.
