AuntieE - yes this is interesting - where we live there are bright lights outside since January on all night for security.
We have blackout blinds, heavy curtains, anti glare film on
the glass, still the light penetrates, birds singing all night.
We have eyemasks too, but still our sleep is disturbed.
Can you provide links to any articles which may provide relief?
Noise too of course, sudden, loud hard noises ie car doors slammed at 2.13 am, or this week we. noticed, heavy planes flying low overnight wake us. We are in an area of airfields.
OH woke startled, ‘are we at war?’
We can become acclimatised to noises its true but screeching screaming! children never, hard wired as we are to sounds of distress and alert, that we are instantly adrenaline fuelled, as in young women in the road late at night, screaming, are they high spirited or in mortal danger.
Screaming without fear should be an offense, it is certainly offensive (to ears)
