Many of us wake up intermittently in the middle of the night for no apparent reason and endure a “witching hour” of wakefulness.
The
most likely causes of this are changes in your environment, stress or age.
Going
way back into our evolutionary pasts, we could only sleep well if we felt safe
and secure. And the same applies today - anything that threatens our feelings
of safety and security will disturb our sleep.
Actually,
we all wake very briefly at the end of each of our sleep cycles, but usually are
blissfully unaware. It’s just a case of rolling over and drifting back to sleep most of the time. But
if something is worrying you or your attention is seized by something going on
in the environment around you, you will become more awake at that point.
Changes
to the nervous system and hormones as we get older also mean that as we
progress through adulthood, our sleep becomes progressively lighter and more
fragmented. Which means we wake up more and find it harder to get back to
sleep. Bummer.
Top tip for a great night’s sleep: Try to make your bedroom feel
isolated, comfortable, safe and secure. (And remember to lock the back door /
turn the oven off etc. etc.)
