and? I disagree with needing more as you get older -I had always heard that also, but I need just as much now as I used ot many years ago. Rather I GET just as much possibly even more than when I was going out at night partying etc.
My body is totally barmy. Some nights I don't want to sleep at all, some night it's four to six hours and occasionally I sleep for a whole day! I have given up fighting with it and just go with the flow - it seems to suit me better. When we travel I seem to sleep less, probably due to excitement, strange beds and pillows etc.
I actually think it might be to do with the diabetes and/or the medication. It used to really annoy me but now I just sleep or don't as I feel like it. It's much cooler ironing in the middle of the night. ;-)))
At the moment being 33 weeks pregnant my sleep is all over the place. My sleep changes every night. I wake regularly throughout the night. I guess it's nature's way of preparing you for the sleepless nights to come.
My amount of sleep does vary depending on whether I can sleep or not !! Some nights I am a very light sleeper and wake up every couple of hours. Also, if I have to get up in the night to go to the toilet, sometimes it can take a while to get back to sleep. Then, if I have to get up early for an appointment, I don't have a chance to get more sleep. I get between 6 and 8 hours sleep. I seem to need at least 7.5 hours sleep to function well.
Having a regular sleep routine is an important part of healthy sleep hygiene. I sleep 8.5 hours almost every night with fail, and that seems to be the ideal amount for me. Everyone is different so it helps to tune in to your individual circadian rhythm for optimal sleep patterns.
