The Bedroom Environment

Temperature

Some people run hot in bed while others sleep somewhat cool. However, any healthy adult will experience a drop in body temperature Trusted Source National Institute of Neurological Disorders and Stroke (NINDS) NINDS aims to seek fundamental knowledge about the brain and nervous system and to use that knowledge to reduce the burden of neurological disease.

This naturally occurs during the initial stages of your sleep cycle because a lower core temperature Trusted Source National Center for Biotechnology Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information. View Source makes you feel sleepy, whereas a higher temperature helps you stay alert during the day.

Whether you only use a top sheet or sleep beneath a thick comforter, many experts agree the ideal bedroom temperature for sleeping is 65 degrees Fahrenheit (18.3 degrees Celsius). This might sound a bit chilly for some, but a cooler thermostat setting helps you maintain a lower core temperature while you sleep.

That said, 65 degrees may not be the best temperature for everyone. A range of 60 to 71.6 degrees Fahrenheit (15.6 to 22.0 degrees Celsius) should be suitable for most sleepers. If you still find these settings too cold, try adding a layer or two to your bedding. If you’re too warm or the weather is particularly hot or humid, consider removing a layer or wearing lighter bedclothes in order to stay cool in bed.

Noise

It should come as no surprise that a quieter bedroom is better for sleep than a louder one. Loud noise disturbances Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information. View Source can cause severe sleep fragmentation and disruption, which in turn can have negative impacts on your physical and mental health. Research even suggests that noise at low levels can cause you to shift to a lighter sleep stage or wake up momentarily.

You should strive to keep your bedroom as quiet as possible by blocking outside noises. The whir of a fan or a soothing white noise machine can effectively mask other sounds and help you fall asleep. Some people also enjoy listening to music when they go to bed.

Light

The circadian rhythms that guide your sleep-wake cycle are heavily influenced by natural light and darkness. During the day, your eyes perceive sunlight and signal the brain to produce cortisol, a hormone that helps you stay alert and energized. At night when darkness falls, your brain then produces another hormone, melatonin, to induce feelings of sleepiness and relaxation.

Exposure to artificial light in the evening can delay circadian rhythms and prolong sleep onset Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.

Studies have found that exposure to light sources with a lux of 10 or higher later in the day can lead to more nocturnal awakenings and less slow-wave sleep, a portion of your sleep cycle that is vital to cell repair and bodily restoration.

Keep your bedroom light levels as low as possible if you like to read in bed before sleep. Dimmer lights will help you fall asleep more easily. Another good rule-of-thumb is to avoid using screen devices – including televisions – in your bedroom.

Mattress and Bedding

Depending on your sleep preferences, you may enjoy the close body contour of memory foam, the gentle support of latex, or the springy feel of a mattress with coils. Some studies have found that a newer mattress Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information.

However, the best mattress for you likely depends on individual factors like body weight, normal sleep position, and whether you prefer lying on a soft or firm surface.

You should also choose your bedding items based on personal criteria. Important considerations for selecting the best pillow include firmness, loft (thickness), and durability. For sheets, the best option for you may come down to whether you prefer a crisp or silky hand-feel and how hot you sleep at night.

A sanitary bedroom is also important for promoting healthy sleep.

Additional Tips for a Relaxing Bedroom

To ensure your bedroom is a relaxing environment that promotes healthy sleep, you should take steps to improve your surroundings.

Many experts agree you should wash your sheets at least once every two weeks. If you sweat excessively in your sleep or share your bed with a pet, you may want to consider weekly cleanings. Routine washings not only prevent dust mites and body oils from building up but can also promote better sleep.

Certain scents can help you feel more relaxed.
