Some ideas:
- make sure the bedding is pure cotton rather than polyester cotton
- if you wear pyjamas, same applies
- if you normally sleep naked, try wearing cotton pyjamas or a cotton t-shirt - although it sounds counterintuitive, your body might find it easier to self-regulate with a layer of clothing
- women have been taking sage tablets or evening primrose oil for hot flushes for centuries - it works for some but not all
- acupuncture really helps some men. In our area, men on HT used to be able to get acupuncture for hot flushes on the NHS in the urology department at our hospital but they stopped it before the pandemic
