Ideal Sleep Temperature = Restful Sleep at Novotel
Creating the ideal sleep temperature when you’re staying in a hotel is an easy and effective micro-habit for boosting energy and mental clarity.
A decent night’s sleep is essential when travelling for business or leisure. An ideal sleep temperature of around 18°C (65°F) is recommended by experts, and Novotel also offers Live N’Dream beds for optimal rest, smart foldable pillows and 100% cotton linens in our spacious, soundproof guest rooms.
It’s often overlooked in favour of more obvious issues – comfortable bed, peace and quiet – but room temperature plays a vital part in the ability to sleep well. A cool – never cold – environment will support your body’s natural circadian rhythm, helping you to get to sleep and stay asleep. When a room is too warm, your body struggles to dissipate heat, leading to restlessness and increased wakefulness. It’s well known that travel exacerbates the disruption of our body clocks, even without the added issue of not sleeping well in an unfamiliar hotel room. Here's what you need to know about ideal sleep temperatures, and how Novotel is improving your sleep experience.
Just what is the ideal sleep temperature?
An ideal sleep temperature of around 18°C (65°F) is recommended by experts because it aligns with your body’s natural internal patterns and the need to drop the temperature of your internal thermostat to initiate a good night’s sleep. There are several reasons for this:
Circadian rhythm regulation: Your body temperature isn’t constant; it follows a natural 24-hour circadian rhythm cycle, which can be disturbed when you’re travelling. Around bed time, your brain starts shedding heat to prepare for rest. A cooler room facilitates this cooling-down process.
- Physical recovery and mental clarity: Blood is sent to your hands and feet to release heat from your core temperature. A room that is warmer than 18°C prevents this from happening, which means your brain and body both stay alert instead of preparing for rest, causing fatigue and mental fog.
- Long-term well-being: The hormone melatonin regulates our sleep-wake cycles, and its production is sensitive to both light and temperature. Cool temperatures encourage our bodies to produce more melatonin, promoting uninterrupted slumber and long-term holistic health.
- Deeper sleep cycles: High room temperatures force the body to sweat to cool down. This causes physical discomfort and can also spike your heart rate, pulling you out of a rejuvenating deep sleep cycle. Sleeping at a constant 18°C – the ideal sleep temperature – will prevent this happening.
- Rapid eye movement sleep: When a room is too warm, your body works harder to regulate its core temperature, often resulting in restlessness and micro-awakenings. The physical effort involved in this interferes with restorative rapid eye movement (REM) sleep – which is highly sensitive to temperature – and means you’re more likely to wake as your body struggles to stay cool.
Good to know: Characterised by increased brain activity, REM sleep is the final stage of sleep, when you dream vividly. It’s often accompanied by muscle and eye movement, disturbed breathing and a fluctuating heart rate, and is vital for increasing brain function, sharpening memory and supporting emotional health.

Mastering the art of hotel sleep: 10 realistic tips for travellers
Whether you’re staying in a city hotel such as Novotel Paris Roissy CDG Convention on business, enjoying a much-needed countryside escape at Novotel Nantes Carquefou or heading to Novotel Antibes Sophia Antipolis for family time in a coastal hideaway, sleeping in a strange bed can be a challenge. The right sleep environment – and optimum temperature – can make all the difference to your personal comfort and energy levels, so start small and use these 10 easy tips to turn your room into a cosy and peaceful sanctuary.
1. Control your environment
Ask for a room on a higher floor, well away from footfall in public spaces. If you’re in a city that lives 24/7, request a room at the back of the hotel and forgo the street views.
2. Test the pillows on arrival
Whether you favour firm support or something softer, the right pillow choice will ensure restful sleep. Most hotels have pillow menus; request any changes on arrival rather than at 11pm when you’re ready for sleep.
3. Set the thermostat
Adjust the room temperature to around 18°C – the proven ideal sleep temperature – when you arrive to help your body’s natural temperature regulation; overheating under the duvet means a restless night.
4. Ditch the nightcap
Tempting as it may be, avoid alcohol before settling down for the night. Drinking a glass of cool water before you go to bed will help you hydrate and lower your internal temperature.
5. Avoid heavy meals
Swap late-night, calorie-laden meals for light, easy-to-digest buffet-style snacks. When your metabolism breaks down stodgy food, it generates heat, causing an increase in core body temperature.
6. Mask any noise
Many hotels have soundproofed guest rooms with double glazing. Occasionally, however, some noise is inevitable. Pack earplugs and noise-cancelling headphones or use a white-noise app to ensure you’re not disturbed by unfamiliar sounds.
7. Personalise the lighting
Exposure to light impacts sleep patterns and destabilises your internal body clock. Most hotels have blackout curtains to block out external light. Switch off bathroom lights and bedside lamps, and if you’re a particularly light sleeper, use a sleep mask to shield your eyes.
8. Switch off devices
Working on laptops or scrolling through Insta grids keeps your mind alert, and the blue light generated by devices suppresses melatonin, the hormone that triggers sleepiness. Switch off your screens an hour before you want to sleep.
9. Surround yourself with familiar things
Always unpack so your belongings are around you. Bringing small comforts like your favourite sleepwear, scent or cuddly soft toy creates a sense of safety, calm and familiarity, so you’re more likely to sleep soundly.
10. Keep to a routine
Stick to a familiar bedtime routine when you’re travelling. Reading, listening to your favourite music or meditating will signal to your body that it’s time to wind down, helping you sleep in hotels.
Good to know: Morning rituals are just as important as night-time ones; to set yourself (and your brain!) up for the day, follow Novotel’s 10-minute morning travel routine.
If you’d like more suggestions for sleeping soundly in hotel rooms, Novotel can walk you through a bedtime routine, help kids sleep soundly and suggest how frequent fliers combat travel exhaustion.
FAQs for the ideal sleep temperature
Does room temperature affect sleep quality?
Ambient room temperatures have a significant impact on sleep quality. The ideal sleep temperature of around 18°C (65°F) helps your body drop its core temperature and prepare for sleep. Being too hot disrupts REM sleep, while excessive cold causes discomfort that will also hinder uninterrupted nights.
Is 18°C too cold for sleeping?
When your bedroom is at the ideal sleeping temperature of around 18°C, melatonin production in your body is initiated, helping you to sleep. It is thought melatonin production can also help with ageing, weight loss and mood.
What is the 3:2:1 rule for sleeping?
The 3:2:1 bedtime rule is a science-backed routine to improve your sleep quality. It helps your body wind down naturally and is particularly useful for business travellers balancing productivity with rest.
- 3 hours before bed: Avoid eating.
- 2 hours before bed: Stop work.
- 1 hour before bed: Switch off screens.
