5 Free Sleep Hacks That Actually Work (From an RLT Expert)

I Sell Red Light Therapy Devices For a Living. But The Best Sleep Hacks I Know Are Completely Free.

Red light therapy can be expensive.

But here's something most people in the wellness industry won't tell you: the most powerful sleep optimisation strategies don't cost a penny. After nearly a decade helping thousands of customers improve their sleep with red light therapy at home, I've learned that devices are the cherry on top — not the foundation.

If you're not sleeping well, everything else suffers. Your energy tanks. Your mood crashes. Your body can't repair itself properly. Sleep is when all the good work you do during the day gets processed and implemented. It's when your body does the heavy lifting of healing, repairing, and rebuilding.

The good news? You can dramatically improve your sleep quality before spending anything on supplements or technology.

Here are five science-backed habits that have transformed sleep for our customers — and they're completely free.

1. Kill The Bright Lights After Sunset

This is the single biggest sleep mistake most people make.

Exposing yourself to bright artificial light at night — from your phone, laptop, or overhead house lights — tricks your brain into thinking it's still daytime. This delays melatonin production, which means your REM and deep sleep cycles start much later than they should. You miss crucial healing windows.

The science is clear: it can take up to three hours after bright light exposure for melatonin production to properly begin. If you're scrolling on your phone or watching Netflix until 10 PM, melatonin might not start flowing until well after midnight. That's a disaster for sleep quality.

What to do instead:

Turn off overhead lights after sunset. Switch to warm yellow, orange, or red lamps positioned below eye level. This is the most sustainable and practical option for modern life.

Wear blue light blocking glasses. They stop blue wavelengths from entering your eyes during evening screen time. Many of our customers at Red Light Rising tell us this single change made them feel noticeably sleepier at bedtime.

Use screen filters. Install software that shifts your devices to warmer red tones after dark. It looks strange for a day or two, then you don't notice it.

Embrace red light in the evening. Pure red light is incredibly relaxing for your eyes and nervous system. Unlike blue-rich light, red wavelengths don't disrupt your circadian rhythm. You can still see what you're doing, but everyone in the house will be calmer and more ready for sleep.

2. Go To Sleep Slightly Hungry

This one requires discipline, but the effects on deep sleep make it absolutely worth it.

Sleep isn't a passive state — it's an active process. Your body and brain run through hundreds of different repair and healing processes while you sleep. If you have food in your digestive system, your body has to prioritise digestion over repair work. That means your deep sleep cycles get delayed or shortened, and deep sleep is where most of the real healing happens.

The strategy:

Eat your last meal three or more hours before bedtime. This gives your body time to finish digesting before sleep begins. Not only will you sleep better, but you'll also find intermittent fasting easier if that's part of your routine.

If you get genuinely hungry before sleep, have herbal tea or water. The goal is to go to sleep slightly hungry, not ravenously so. You want your stomach settled, not growling.

3. Wake Up With The Sun

Your circadian rhythm — your body's 24-hour internal clock — starts counting from the moment light first enters your eyes in the morning.

Wake up as close to sunrise as possible and go outside. Get sunlight on your face, chest, and especially into your eyes. It's the bright blue and green wavelengths, combined with near-infrared light in the sunrise spectrum, that signal your body clock to start the day.

This is why artificial indoor lighting doesn't have the same effect in the morning. It's missing the infrared wavelengths your body is looking for. That early morning sunlight helps reset your body clock, making you feel genuinely alert during the day and naturally sleepy at night.

The consistency factor:

Wake up and go to sleep at the same time every day — yes, even on weekends. Your body will learn to expect sleep at that time and optimise all its repair processes accordingly.

Absolutely everything that you can should be done at the same time daily. First meal at the same time. First coffee at the same time. Evening walk at the same time. Consistency is everything when it comes to circadian rhythm health.

4. Cool Down Your Body Temperature

For your body to drop into restorative sleep as quickly as possible, your core temperature needs to decrease by a few degrees.

Here's how to help that process along:

Sleep with your arms and legs outside the covers. Your extremities are key temperature regulation zones. Exposing them helps your core temperature drop faster.

Take a cold shower before bed. Or soak your hands and feet in cold water. Some of our customers swear by a quick ice bath if they have access to one.

Sleep on top of the covers initially. Get into bed when you're slightly cold. It helps you drift off faster. Obviously, if you're too cold you won't sleep either — find your sweet spot.

Go to sleep as early as practical. You need as much sleep as possible before midnight. The sleep you get in the first few hours of the night tends to be the most restorative.

Keep your bedroom cold and dark. Most sleep experts recommend around 16-19°C (60-67°F) for optimal sleep.

5. Turn Your Bedroom Into a Sleep Sanctuary

If your bedroom is used for multiple activities or feels cluttered and busy, your nervous system won't fully switch off when you get into bed.

Create a proper sleep environment:

Use blackout blinds to block all external light. Even small amounts of light can disrupt sleep quality.

Remove devices from your bedroom entirely. No phones, no laptops, no tablets. Charge them in another room.

Switch off sockets and Wi-Fi. Cut all unnecessary electricity going into your bedroom. Cover small LED lights from chargers or devices with tape.

Reduce clutter around your bed. Keep the space calm and minimal. Your bedroom should signal to your brain: this is where we rest.

Reserve your bed for sleep and intimacy only. Don't work from bed. Don't scroll social media in bed. Train your brain to associate your bed with sleep.

Give your sleep the attention it deserves. When you treat your bedroom as a genuine sanctuary, your body responds accordingly.

So Is Red Light Therapy Useless If I Haven't Done All This?

Absolutely not.

Red light therapy can support healthy sleep patterns regardless of where you're starting from. Many of our customers report feeling more relaxed and experiencing better sleep quality when they use red light therapy in the evening as part of their wind-down routine.

But here's the thing: there's so much free benefit to gain from these foundational habits that it would be a shame not to maximise them first. Red light therapy works best when it's the cherry on top of solid sleep hygiene — not a band-aid over poor habits.

The right order of operations:

Master the free fundamentals first. Get your light exposure right. Optimise your eating window. Create a proper sleep environment. Then, if you want to take things to the next level, explore tools like red light therapy that can support your body's natural processes even further.

At Red Light Rising, we've been helping people optimise their wellness routines since 2017. We've seen thousands of customers transform their sleep, energy, and recovery. The ones who get the best results? They're the ones who nail the basics first.

Start Tonight

You don't need to implement all five of these habits at once. Pick one or two that resonate most with you and start there. Maybe it's dimming your lights after sunset. Maybe it's setting a consistent bedtime. Maybe it's finally banishing your phone from the bedroom.

The beauty of these strategies is that they compound. Each one makes the others work better. Your circadian rhythm will thank you. Your energy levels will thank you. Your body's ability to heal and repair will thank you.

Give these free sleep hacks a proper try for two weeks. Track how you feel. Notice the changes. Then, if you're ready to explore how red light therapy at home can support your routine even further, we're here to help.
