A good night’s sleep is essential for overall health, yet many people struggle with sleep disturbances without realising that their environment plays a significant role.
Factors like air quality, humidity levels, and temperature can directly impact sleep quality, affecting how well you rest and how refreshed you feel in the morning.
By optimising these elements, you can create a comfortable sleep environment that promotes deeper, uninterrupted sleep.
How air quality affects sleep
Indoor air quality is known to have a higher concentration of pollutants and different health risks compared to outdoor air. Poor air quality can lead to nasal congestion, respiratory irritation, and an increased risk of sleep apnea.
Research from Penn Medicine suggests that exposure to indoor air pollution, among other factors like heat and noise, is linked to lower sleep efficiency and increased nighttime disturbances.
Common indoor pollutants that affect sleep
-
Dust and allergens – Accumulate in bedding, carpets, and furniture.
-
Pet dander – Can trigger allergies and worsen asthma symptoms.
-
Volatile organic compounds (VOCs) – Released from paints, furniture, and cleaning products.
-
Mould spores – Thrive in humid environments and can cause breathing difficulties.
How to improve indoor air quality for better sleep
- Increase ventilation – Open windows regularly to allow fresh air to circulate.
- Use an air purifier – A high-quality air purifier, like the Ionmax+ AIRE can remove allergens, pollutants, and airborne particles, making the air cleaner and easier to breathe.
- Keep your bedroom clean – Regularly dust and vacuum to reduce allergens.
- Avoid strong chemicals – Switch to low-VOC cleaning products to limit exposure to toxins.
The best humidity level for sleep
Humidity plays a crucial role in maintaining a comfortable sleep environment. The Sleep Doctor suggests that the ideal indoor humidity level for sleep is between 40% and 60%.
Effects of low humidity on sleep
- Dry air can lead to dry skin, irritated nasal passages, and throat discomfort, making it harder to fall and stay asleep.
- Increased susceptibility to illness – Dry air can weaken the body's natural defenses, making you more prone to colds and respiratory infections.
Effects of high humidity on sleep
- Excess moisture can cause mould growth, dust mites, and increased allergens, leading to congestion and sleep disruption.
- Hot and sticky conditions – Too much humidity makes it harder for the body to cool down, leading to discomfort and restlessness.
How to maintain the ideal humidity level
- Use a humidifier – If the air is too dry, a humidifier can add moisture to the air for better breathing and skin hydration.
- Use a dehumidifier – If humidity is too high, an Ionmax desiccant dehumidifier can help reduce excess moisture, preventing mould and allergens from thriving.
- Monitor humidity levels – A hygrometer can help you track indoor humidity and adjust accordingly.

The best temperature for sleep
Temperature regulation is another key factor for high-quality sleep. The Sleep Foundation suggests that the optimal bedroom temperature for sleep is approximately 18°C or 65°F.
Why temperature affects sleep
🥵 Too hot? A warm room disrupts the body's natural thermoregulation, leading to sweating, tossing, and turning.
🥶 Too cold? A chilly bedroom causes muscle stiffness and difficulty relaxing, making it harder to fall asleep.
How to keep your bedroom at the right temperature
- Adjust thermostat settings – Set your air conditioner or heater to maintain a comfortable range.
- Use breathable bedding – Opt for cotton or linen fabrics to prevent overheating.
- Dress appropriately – Wear light sleepwear in summer and layer up in winter for maximum comfort.
Creating the right environment for ideal sleep
A well-balanced sleep environment is about more than just a comfortable mattress or blackout curtains—air quality, humidity, and temperature all play a vital role in ensuring a restful night’s sleep.
The right combination of these factors can help you wake up feeling refreshed and energised.
- Regulate humidity levels – If your home is too dry, a humidifier can help maintain optimal moisture to prevent dry skin and nasal discomfort. If it’s too humid, a dehumidifier can reduce excess moisture, preventing discomfort and mould growth.
- Improve air quality – An air purifier can remove airborne pollutants like dust, pet dander, and allergens, making it easier to breathe at night.
- Choose the right appliance for your needs – Every home is different, so select a humidifier, dehumidifier, or air purifier based on your specific indoor environment.
By making these small adjustments, you can create a comfortable, restful environment that promotes deep and uninterrupted sleep.
