Numerous studies have established a connection between a good night's sleep and health. It’s when your body repairs, strengthens defenses, and fights off infections. When you don’t get quality sleep, everything from your energy levels to your immune system takes a hit. Your body produces fewer infection-fighting cells, inflammation increases, and you become more vulnerable to colds, flu, and other illnesses.
Poor sleep can result from many factors – but your mattress is probably the biggest culprit. If your mattress is old, unsupportive, or filled with allergens, it can disrupt your sleep differently. And when it does, it’s a direct hit to your immune system.
The Role of Sleep in Immune Health
Sleep plays a critical role in keeping your immune system functioning correctly. While you sleep, your body produces and releases cytokines—proteins that help regulate immunity and inflammation. These cytokines are essential for responding to infections and reducing inflammation. Without enough sleep, cytokine production drops, making it harder for your body to fight viruses and bacteria.
Your body also produces more white blood cells during sleep. These cells are the backbone of your immune response, identifying and eliminating harmful invaders. When sleep is disrupted, these infection-fighting cells decrease, making you more susceptible to illnesses.
Inflammation also increases when sleep quality declines. Chronic inflammation is linked to a weakened immune response and higher disease susceptibility. Poor sleep can even affect the effectiveness of vaccines, reducing your body’s ability to build immunity.
How Your Mattress Affects Your Immune System
You might not think about your mattress much, but waking up tired, achy, or congested could be messing with your sleep and your immune system. Your body does some of its most crucial repair work while you sleep. It fights off infections, reduces inflammation, and strengthens your defenses against illnesses.
But when your sleep is interrupted, your immune system doesn’t get the time to recharge. And that makes you susceptible to infectious diseases like flu, norovirus, RSV, COVID, and even bird flu. Let’s talk about how your mattress might be working against you—and what you can do to fix it.
Poor Support Throws Off Your Sleep
Ever wake up with a stiff back or sore neck? That’s a sign your mattress isn’t doing its job. If it’s too soft, too firm, or sagging in the middle, your spinal alignment is all over the place. That puts extra pressure on your muscles and joints, making it hard to relax fully.
Your body needs to settle into deep sleep—especially the REM sleep cycle, when your immune system kicks into high gear. But if you’re constantly shifting around to get comfortable, your brain stays too alert. That means less time for your immune system to build up its defenses and produce the white blood cells that fight diseases.
A good mattress should support your spine in a natural position, keeping pressure off your back, neck, and hips. If you wake up sore, it’s a sign your mattress isn’t cutting it.
Dust Mites and Allergens Mess with Your Immune System
If you wake up feeling stuffy, sneezy, or like your nose is blocked, your mattress might be the reason. Over time, dust mites, bacteria, and even mold can build up inside, especially if you live in a humid climate or don’t use a mattress protector.
Breathing in these allergens every night can trigger inflammation, making your immune system work overtime. It also messes with your circadian rhythm, the natural cycle that tells your body when to rest and recover. If your body is constantly dealing with low-level inflammation, it’s harder to fight off bigger threats—like colds and flu.
Switching to a hypoallergenic mattress or using a mattress protector helps reduce allergens. Washing your sheets regularly (at least once a week) and vacuuming your mattress every few months can also make a big difference.
Overheating Interrupts Deep Sleep
Night sweats could be a sign that your mattress is not breathable enough. Some mattresses, especially ones made from dense foam, trap heat and make it harder for your body to stay at the right temperature.
Your body naturally cools down when you sleep, which helps you stay in deeper, more restorative sleep stages. But if your mattress keeps too much heat, you’ll wake up more often—interrupting those crucial immune-boosting cycles.
A breathable mattress material like latex or gel-infused memory foam helps regulate temperature, keeping you cool and comfortable. Look for a mattress designed for airflow, or add cooling sheets and pillows for an extra bit of relief.
Stress and Poor Sleep Weaken Your Defenses
When you don’t sleep well, your body produces more stress hormones. That messes with your nervous system raises your heart rate and increases inflammation—all of which make your immune system less effective. Chronic stress has even been linked to cardiovascular disease and a higher risk of getting sick.
A comfortable, supportive mattress can make a huge difference in stress reduction. When your body feels supported, it relaxes more easily, making it easier to drift into deep, healing sleep. That means better recovery, a stronger immune response, and fewer sleepless nights worrying about why you’re so exhausted.
How to Keep Your Mattress (and Immune System) in Top Shape
Want better sleep and a stronger immune system? Here’s what you can do:
-
Clean your mattress regularly. Dust mites and bacteria love an old, unclean mattress. Vacuum it every few months and use a mattress protector to keep allergens out.
-
Wash your sheets at least once a week. Clean bedding keeps dust and allergens from building up. Hot water is best for killing germs.
-
Check your mattress for signs of wear. If it’s sagging, lumpy, or over 8 years old, it’s time for a new one.
-
Choose breathable, hypoallergenic materials. A hypoallergenic mattress with cooling, breathable mattress materials can help prevent allergens and regulate temperature.
-
Invest in the right support. A mattress that keeps your spine aligned reduces muscle tension, helping you stay in deeper sleep for longer.
