The trick isn’t new, but viewers were left astonished they hadn’t thought of it yet.
Last summer, TikTok user gained almost a million views for her video, in which she said she puts the water bottle in the freezer all day before placing it in her bed an hour before her bedtime.
She says: “Put it in your pillowcase, or just rest on it – it’s amazing!”
Warnings
However, Sam did have some warnings for those wanting to try the hack.
She wrote: “Three things – 1) Please don’t do this too often as the ice can damage the seal.

“2) Only fill it 2/3s up as it expands!!
“3) Be careful of ice burns.”
Other experts have warned of the risks of the hot water bottle hack because the rubber can be stretched and then burst in the future.
This could be seriously dangerous if there is hot water inside.
Rebecca Challinor, a product specialist at the retailer Terrys explained to : “Whilst freezing your hot water bottle can be an effective way to have a better night’s sleep in hot weather, it’s advisable once you’ve done this to no longer use the same water bottle during the winter.”
