How Do Old Mattresses Affect Your Health?

health effects of old mattresses

Do you feel drowsy even in the mornings? This may be the effect of low quality sleep. The quality of your sleep depends on your mattress. Even the best mattresses need to be replaced at some time. Though there is no standard life span of a mattress, it is advisable to replace it every 8 years.

Although you can prolong the life by rotating it, it does not solve all the problems as there are still millions of bed bugs that can affect your respiratory health.


An old mattress is not as comfortable and firm as the new one and can affect a lot more than just your sleep. Irregular sleeping patterns or sleep deprivation can lead to many health problems.

1. Increase Stress Levels

Lack of sleep can increase stress levels


Stress can be caused due to many reasons. An old mattress could be one of them.

Sleep is usually affected when the mattress is uncomfortable. Lack of sleep can intensify the degree of stress.1


Inadequate sleep increases your cortisol levels, which is responsible for increasing your stress levels. To keep your stress levels at bay, getting enough sleep is necessary.

2. Trigger Allergies

All mattresses contain dust mites. But old mattresses, in particular, contain a large number of dust mites, bed bugs, and bacteria, that can trigger allergic reactions. Over time, your mattress collects dead skin and body oils and these microscopic creatures feed on the dead cells that your body sheds.

Dust mites also cause skin problems like eczema and also damage your lungs leading to respiratory problems. Dust mites can be especially harmful to people with asthma.


3. Drowsiness

old mattresses disrupt sleep

An old mattress can prevent sufficient sleep which results in you feeling drowsy and tired all the time. If you are unable to get proper rest at night, you may not feel energized the next day.


When the mattress is old, it is no more firm enough to support your body, which in turn affects your sleep.

4. Neck Pain/Back Pain

old mattresses cause back pain or neck pain


Old mattresses can promote back pain or neck pain and prevent a good night’s sleep. For proper body support, your mattress needs to be medium-firm.2

Old mattresses may not provide the required body support as they become saggy over time and your lower back and neck is under continuous strain.

5. Obesity

lack of sleep leads to obesity

An uncomfortable mattress can keep you awake in the night. People who are unable to sleep during the night are at a higher risk of becoming obese.3 Sleep deprivation is linked to overeating and unhealthy eating patterns that eventually lead to weight gain.

People who don’t get enough sleep may take in more calories than those who do, simply because they are awake longer. Lack of sleep also disrupts the balance of key hormones that control appetite, so sleep-deprived people may be hungrier than those who get enough rest each night.4

6. Promotes Snoring

old mattresses cause snoring

Snoring is a common disorder. When you are sleeping on a worn out mattress, your airways may be under tension as your body is not well-supported and this leads to snoring and discomfort.

Dust mites in old mattresses can cause irritation in the airways and increase the risk of snoring, by making breathing difficult.

7. Heart Problems

lack of sleep leads to heart problems

Sleep is essential for a healthy heart. Your cardiac health is affected if you don’t get enough sleep.5 The risk of developing a heart disease increases when you don’t get sufficient sleep.

Insufficient sleep is also associated with high blood pressure, as well as a heightened risk of stroke.

A good night’s sleep is important for your wellbeing. Replace your old mattress for a healthier heart and a sound sleep.
