To keep cool at night......wear cotton nightwear...have a tepid shower before turning in for the night.......fill a 2 litre drink bottle and put into the fridge, take this to bed and pop your feet on it during the night......if you can cool your feet the rest of you usually will stay cool.
Those are my tips for keeping cool......oh, I also take a moist face cloth with me to bed and moisten my limbs...this mimics perspiring and keeps you cool.

For those of you disturbed by the light......a blackout blind does the trick...or the cheap version is to wear the nightmasks that they give you on laong haul flights.
