Hot flushes in the middle of the day
Short answer: Wear a thin layer against the skin that absorbs moisture, and an outer layer you can take off in five seconds. Layers are the only thing that works when temperature changes without warning.
Why layers are the answer
A hot flush comes and goes in minutes. A thick garment can neither be removed fast enough nor put back on afterwards. Two or three thin layers can be adjusted on the move without needing somewhere to change.
The layer against the skin
The innermost layer should absorb the moisture before it reaches the outer one. Bamboo viscose does exactly that and releases the moisture to the air afterwards. See bamboo undershirts for women.
Colours and fabric
Marl and mid dark colours hide damp marks best. Avoid light grey, which shows the most. See bamboo t-shirts for women and bamboo tops for women.
Frequently asked questions
Does the material really help
It does not change the flush, but it does mean you are dry again sooner afterwards.
What about underwear
A thin layer that sits close moves moisture best. Loose fabric does less.
Should you talk to a doctor
If it affects your daily life or your sleep, talk to your doctor about causes and options.
