White Noise and Relaxation Machine
Guided Progressive Muscle Relaxation
Use the soothing female or male voiced guided relaxation to release all the tension in your body. Whilst sitting or lying in a comfortable position, you are guided through a sequence from head to toe over 15–20 minutes.
Use at any time of day to de-stress and unwind. At night, it places your body and mind in the perfect state to drift gently into the deep, refreshing sleep you need.
→ Deep physical relaxation — tension released muscle group by muscle group
→ Tense groups of muscles one at a time, then release
→ Appreciate the sensation of relaxation as each group lets go
→ Feel the wave of relaxation wash over you
The technique is Progressive Muscular Relaxation — one of the most well-evidenced approaches in clinical sleep medicine, based on Bernstein and Borkovec's standardised protocol. Dr James Mackin developed the script; he and Heidi recorded it together. The free ebook explains the clinical rationale behind it in full.

Perfect for Children and Infants
The sound menu includes dedicated sounds for babies and young children — a shushing sound, a reassuring heartbeat, and three lullabies. Combined with the adjustable night light and environment monitors, SoundSleeper has everything needed to create a calm, safe sleep environment for little ones as well as adults.
Night Light — Set the Perfect Mood
Adjust the ambiance of the sleep environment with the built-in night light.
• 7 colours •
• 6 brightness levels •
• 2 breathing rhythms (gentle pulse to ease you toward sleep) •
Sleep Environment Monitoring
Temperature and humidity are two of the most underestimated factors in sleep quality. The ideal bedroom sits between 16–18°C with 40–60% relative humidity — SoundSleeper displays both in real time, so you can act on what you see rather than guess.
Clock, Alarm & Timer
Digital clock display
Programmable alarm with snooze function
Auto-off timer: 30, 60, 90 or 120 minutes
Power & Portability
SoundSleeper is USB-C powered — a USB-A to USB-C cable is supplied. You can power it from any standard USB mains adapter (not supplied), a USB port on a laptop, a car USB socket, or a portable powerbank (not supplied).
The internal rechargeable battery provides up to 8–12 hours of use — a full night, untethered. Use it completely wire-free on your bedside table, or take it travelling without needing a socket.
⚠ First charge: please charge for 24 hours before first use to bring the battery to full capacity. Battery life will be significantly reduced if this step is skipped.

eBook
Most sleep advice is recycled. This isn't.
Restore Your Sleep was written by Dr James Mackin — a practising NHS GP with over 20 years in family medicine — after years of frustration with the absence of a genuinely complete, accessible sleep solution for patients.
It doesn't tell you to 'try to relax.' It explains why relaxation techniques work, what the evidence says, and exactly what to do — across 23 action points with full academic references.
The 23 Action Points Cover
→ Recognising underlying medical conditions that disrupt sleep
→ Circadian biology — your body clock, light cues and melatonin timing
→ The Five Frustrations: light, sound, temperature, unsupportive bed, untidy room
→ Self-inflicted disruption: alcohol, caffeine, nicotine, medication, screens and dopamine
→ Food, exercise, sex and scent as sleep tools
→ Melatonin — what the evidence actually says
→ CBT for Insomnia (CBT-I): stimulus control and sleep restriction
→ Mental housekeeping: to-do lists and bedtime rituals
→ The full PMR script — based on Bernstein and Borkovec's standardised technique
Who It's For
Anyone who has tried basic sleep hygiene and found it insufficient
People with anxiety or stress-related insomnia
New parents managing disrupted nights
Shift workers with circadian disruption
Over-55s looking to reduce reliance on sleep medication
Anyone who wants to understand the science, not just follow a list
