Back Sleeping: What It Does To Your Body

what happens when you sleep on your back

Sleeping on your back, also known as supine sleeping, may be a solution to a host of ailments, from sleep issues to health woes. It can help with spinal alignment, prevent wrinkles, and relieve symptoms of allergies, asthma, and shoulder pain. However, it may not be suitable for everyone, as it can worsen heartburn, snoring, and sleep apnea. Additionally, pregnant women should consult their doctors before adopting this sleeping position. Strategic placement of pillows can enhance comfort and support for back sleepers.

It can help prevent wrinkles and fine lines

Sleeping on your back can help prevent wrinkles and fine lines in several ways. Firstly, it keeps your skin care products on your face and off your pillowcase, ensuring that the active ingredients in your skincare products are absorbed by your skin rather than being transferred to your pillowcase. Secondly, back sleeping helps to keep your face off the pillow, preventing face-to-pillow contact and the friction that comes with it. This friction, also known as "wrinkle-inducing friction", can cause the collagen and elastic tissue in your face to break down over time, leading to the development of wrinkles and fine lines.

Sleeping on your back also helps to prevent the premature development or deepening of wrinkles and lines by keeping your neck straight. When you sleep on your side or stomach, your face is pressed against the pillow, and the pressure and friction can lead to wrinkles and fine lines. Additionally, when you lie on your back, you avoid face-to-pillow contact, which can cause your skin to fold" into the pillow, creating pressure on your face that contributes to wrinkle formation.

To enhance the wrinkle-preventing benefits of back sleeping, it is recommended to elevate your head slightly. This helps to control fluid buildup, which can cause puffiness and swelling in the face, contributing to the formation of wrinkles. Elevating your head can also help relieve congestion and prevent the clogging of nasal passages, reducing the risk of sinus issues that can contribute to wrinkle formation.

While back sleeping can be an effective way to prevent wrinkles and fine lines, it may not be comfortable or feasible for everyone. Some people may find that it increases discomfort in their lower back or exacerbates conditions such as sleep apnea. Strategic pillow placement, such as using a pillow under the knees or lower back, can help make back sleeping more comfortable. However, it is important to listen to your body and choose a sleep position that works best for you.

It may reduce spinal pain

Sleeping on your back may reduce spinal pain, depending on the mattress and pillow you use. When you lie down, your body weight is more evenly distributed, alleviating the strain on your spine from daily activities. A firm or medium-firm mattress provides support for the spine, distributing body pressure more evenly, which reduces pain when lying down or after getting up.

However, if you lie flat on your back on a soft mattress, your lumbar spine might bend forward, compressing the discs and worsening disc pain. To prevent this, you can place a pillow or two underneath your knees to align your spine better and reduce lower back pain. This position helps with low back pressure and supports the gap in your lower back.

Additionally, when you sleep, your body undergoes tissue repair and regeneration, aiding the repair of damaged spinal tissues and maintaining spine health. Sleep also allows the muscles around the spine to relax fully, promoting deep relaxation and reducing the likelihood of muscle imbalances or strains that contribute to back pain.

While sleeping on your back may help reduce spinal pain, it is not a suitable position for everyone. If you cannot sleep on your back, try sleeping on your side with your legs elongated to maintain a neutral spine.

It can relieve congestion

Sleeping on your back can help relieve congestion by aiding mucus drainage from the sinuses. When lying flat on your back, gravity causes blood to pool in your sinuses, increasing pressure and discomfort, and making it harder to breathe through your nose. Elevating your head with extra pillows can help to alleviate these symptoms by allowing your sinuses to drain more effectively, reducing congestion and improving breathing.

The position of your head can affect how congested you feel. Lying down can increase blood flow to your head, causing swelling in the nasal blood vessels. This can lead to a stuffy nose, which is often worse at night due to your horizontal sleep position. By sleeping on your back with your head and shoulders elevated, you can help your sinuses drain and relieve congestion.

A wedge pillow can be used to elevate your upper body and keep you in the correct position, as it provides a gradual incline that is more comfortable and effective than stacking regular pillows. Sleeping with your head propped up on a pillow may also help relieve decongestion. Nasal congestion may prevent you from breathing fully, which could impact your sleep.

In addition to sleeping on your back, there are other ways to relieve congestion. Warm drinks such as herbal or decaffeinated teas can help soothe inflammation in the nose and throat. A hot shower before bed can help loosen mucus, and a humidifier can add moisture to the air, preventing your nose from drying out. Nasal sprays and neti pots can also help your sinuses drain overnight.

It may worsen sleep apnea

Sleeping on your back may worsen sleep apnea. Sleep apnea is a condition that causes interruptions in breathing during sleep. These interruptions can range from shallow breaths to complete cessations of breathing, and they can occur multiple times throughout the night. Sleep apnea can lead to serious health complications, including high blood pressure, stroke, and heart disease.

When sleeping on the back, the tongue and jaw can relax and narrow the airway, potentially blocking it. This blockage can cause snoring, which is a common symptom of sleep apnea. Snoring occurs when the airway is partially blocked, causing the tissues of the throat to vibrate. Back sleeping may also worsen existing snoring, as it can increase the likelihood of the tongue and jaw blocking the airway.

Additionally, sleeping on your back may contribute to acid reflux, which has been linked to sleep apnea. Acid reflux occurs when stomach acid flows back up into the oesophagus, causing heartburn and irritation. Sleeping on the back can worsen acid reflux by allowing stomach acid to flow more easily into the oesophagus. This can irritate the throat and airways, further narrowing the airway and exacerbating sleep apnea.

It is important to note that while sleeping on your back may worsen sleep apnea, it is not the only factor contributing to the condition. Other factors, such as weight, age, and family history, also play a role in the development and severity of sleep apnea. Therefore, it is always advisable to consult a doctor or sleep specialist for personalized advice and treatment options.

It can help with allergies

Allergies can significantly impact sleep quality. Allergic rhinitis, for instance, affects up to 40% of Americans, causing symptoms such as sneezing, an itchy or runny nose, and watery eyes. Allergies can also lead to insomnia, with sufferers experiencing twice the likelihood of insomnia compared to non-allergic individuals.

One way to potentially alleviate allergy symptoms and improve sleep is to sleep on your back. Sleeping on your back can reduce congestion and post-nasal drip, as it keeps your head elevated above your body, aiding in the drainage of secretions. This position can be more comfortable than sleeping on your stomach, which may trigger allergies due to increased contact with potential allergens in the pillow.

Additionally, there are other strategies to manage allergies and improve sleep:

  • Medication: Antihistamines and decongestants can provide relief from congestion and post-nasal drip. Inhaled nasal steroids and intranasal antihistamines are also effective in addressing all four allergy symptoms: sneezing, itching, runny nose, and mucus formation, as well as nasal congestion and swelling. It is important to consult a doctor before changing your medication routine.
  • Bedroom environment: Keeping windows closed can minimize pollen from entering the bedroom. Using air purifiers or air conditioners with HEPA filters can also improve indoor air quality by reducing common household allergens like mold, dust mites, pet dander, and pollen.
  • Bedding and mattress: Allergy-causing dust mites thrive in pillows, bedding, and mattresses. Washing your bedding regularly with warm water and soap can help eliminate dust mites. Using dust mite covers for mattresses and pillows can also reduce exposure, but these covers may prevent airflow, so a lightweight blanket is recommended.
  • Personal hygiene: Showering before bed helps remove pollen and other allergens from your skin and hair. Changing out of outdoor clothes and putting on clean pyjamas can also reduce allergen exposure.
  • Pet ownership: Pet hair and dander are common allergens. Sleeping in a separate room from your pet and washing your hands after contact can help alleviate allergies.
