Why tumble drying bedding on high heat does more harm than good

January 13, 2026

When it comes to laundry, the convenience of tumble drying is unquestionable, yet many overlook the significant impact of using high heat settings, particularly for bedding. While tossing sheets and pillowcases into the dryer on a high heat cycle may seem efficient, it can lead to various issues with fabric longevity and overall comfort. High temperatures, typically ranging from 140°F to 150°F, can cause substantial wear and tear on fibres, resulting in premature deterioration of sheets and bedding. In the quest for softness and cleanliness, many homeowners fail to recognise the detrimental effects high heat can have, including shrinkage and color fading. This article explores why opting for lower heat settings may be the wiser choice for maintaining the quality of bedding while promoting energy efficiency.

The Risks of High Heat Tumble Drying Bedding

Tumble drying on high heat can introduce several risks that compromise the integrity of bedding materials. Most notably, high temperatures can lead to fabric damage that manifests as thinning or weakening of fibres. This not only shortens the lifespan of sheets but can also result in rough textures that detract from the overall sleeping experience. For those who appreciate the benefits of a comfortable and safe sleeping environment, understanding how high heat affects bedding is crucial.

Why Avoiding High Heat Is a Smart Move

Choosing to skip the high heat setting can yield numerous benefits. Firstly, lower temperatures—generally around 120°F to 125°F—allow bedding to dry evenly without exposing it to extreme conditions. This gradual drying process is particularly essential for delicate fabrics, such as linens and blends, which are especially vulnerable to damage. When bedding is subjected to excessive heat, the risk of shrinkage increases, leading to ill-fitting sheets and a disrupted sleep experience. Moreover, many high-performance materials, designed for improved breathability or moisture-wicking, may be rendered ineffective through harsh drying methods.

Energy Efficiency and Cost Savings

Utilising lower heat settings not only protects bedding but also aids in energy consumption strategies that are increasingly important in today’s environmentally-savvy climate. Lower temperatures consume less energy over time, contributing to reduced utility bills. While it may take slightly longer for items to dry, the safety and durability of the bedding make the extra time worthwhile. In 2026, households striving for sustainability can benefit from adjusting their tumble drying habits to maximise efficiency and minimise their carbon footprint.

The Right Choices for Tumble Drying Bedding

For those seeking the best results when tumble drying bedding, it’s crucial to understand when to adjust settings. Many modern dryers offer specific cycles tailored for different materials, allowing users to select options like “delicate” or “permanent press,” which are gentler on fabrics. Integrating a wool dryer ball into the load can also enhance drying efficiency by promoting better airflow and reducing drying time without compromising fabric integrity. It’s essential to check care labels before throwing items into the dryer: materials such as bamboo and silk require careful treatment to avoid heat damage.
