Have been off work this week and hence sitting up pretty late (I usually go to bed around 1-2am as I work the late shift, so 'late' for me is 3-4am).
I'm currently renting whilst looking for a place to buy (moved fairly recently) and have storage heaters, which means I can run out of heat if I don't set them high enough the night before.
Most evenings I've had the built in electric heater on for a bit, often a quick blast every couple hours to 'top up', but without fail I've got the windows wide open after midnight. I thought it was the heat build up from my tv after Netflix binging for several hours, but tonight I've only been on my iPad and once again I've opened the window.
Is it the heat retained in the walls during the day releasing or something, or am I suffering the male menopause?
