As the UK braces for potential temperatures of 28°C this weekend, experts are urging Brits to try an unusual but effective hack: sprinkling baking soda on their beds. This simple trick can help combat the increased sweating that comes with warmer nights.
Why You Sweat More in Summer
According to Mattress Online, sweat loss during sleep rises by 76.9% in summer compared to winter. The average person loses half a litre of fluid overnight during hot weather, which can seep into mattresses and cause bacteria growth and unpleasant odours.
The Baking Soda Solution
Hannah Shore, Head of Sleep Science at Mattress Online, recommends sprinkling a small amount of baking soda on your mattress. The alkaline powder neutralises the acidity of human sweat, acting as a natural deodoriser. It also absorbs moisture trapped deep in mattress fibres, which you can then vacuum away.
For best results, let the baking soda sit for at least an hour—or longer if possible—before vacuuming thoroughly. This process helps keep your mattress smelling clean and fresh throughout the summer.
Additional Mattress Cleaning Tips
- Wash pillows, sheets, and duvets in a hot wash to kill germs and dust mites.
- Vacuum the bare mattress in small sections, focusing on seams and corners.
- Spot clean stains with a mild detergent and warm water solution, using a damp cloth without over-soaking.
- Air the mattress thoroughly before replacing bedding. If double-sided, flip and repeat the process.
By incorporating baking soda into your cleaning routine, you can extend the life of your mattress and enjoy a more comfortable sleep during heatwaves.
