How Can an Air Purifier Improve Sleep?
The quality of both sleep and the air around you significantly affect your health. You’re at risk of illness and sleep disruptions if you spend your night inhaling dust, allergens, and harmful chemicals. Harmful air particles create difficulty breathing, inflammation, viruses, and many more symptoms.
An air purifier improves your sleep health by filtering out pollutants in the air, making it difficult to fall asleep and stay well-rested. The HEPA filter traps particles of all sizes to reduce allergens and bacteria, while activated carbon can absorb odors and harmful chemical gases such as wildfire smoke.
To achieve deep sleep, you need to make sure to limit any distractions, so you may want to look an air purifier that has a sleep mode setting which automatically darkens the display light and prompts the device to run at a quieter level. The best air purifiers for sleep offer soothing sounds and alleviate allergy symptoms to help you fall asleep faster and stay asleep longer to achieve the recommended seven of sleep you need each night.
In fact, air purifiers with pink noise — such as the Alen BreatheSmart 45i — help reduce distracting noises that interrupt your sleep, including loud talking or someone snoring. Pink noise instead provides low, relaxing background noise, helping you fall asleep faster and improving the depth of your sleep. Ultimately, this means you’ll get the necessary rest you need to feel rejuvenated and tackle the coming day.
