<p>I thought it was a myth too, until I tried the SHEEX cooling pillowcases. There’s a fabric with heat dissipation technology, and – amazingly – it works! Before that, I didn’t know how to always have a cold pillow . Now I put the pillow the same way all night and it stays cool. Even my son has noticed it – now he’s asking for one just like it. A small change, and how much it improves the quality of sleep.</p>
