I have been using my double wool duvet (2-5 tog) for just over a week. I am going through the menopause and was struggling to sleep due to hot sweats at night. I came across Wool room on a search and read that using a wool duvet can help manage your body temperature because it can keep you cool when hot and warm enough when cold. I was not sure if it would make a difference as a lot of claims can be made on products but the proof is in the test.
Not sure if it’s because it is a lower tog but glad to say that it has not let me down and I have been sleeping better.
