Australian guidelines say adults between the ages of 18 and 65 should have 7 to 9 hours of sleep each night while those over 65 need 7 to 8 hours.

00:00We all know how it makes us feel. We don't feel particularly happy or sprightly or perhaps
00:07a bit more grumpy, a bit shorter than usual with our loved ones. But yeah, there are lots
00:12of negative health consequences, things like cardiovascular diseases, mental health disorders,
00:19things like we're more at risk of developing things like diabetes, we're more prone to
00:24making mistakes when we're at work, which obviously, you know, if you aren't putting
00:31a number in a spreadsheet, that's not a problem. But if you are driving a vehicle, that may
00:35be a problem. And then things like reproductive health, it affects our immune health, just
00:42about every system in our body is impacted by having insufficient sleep. Sleep regularity,
00:49we know is really important. So getting up at the same time each day, going to bed at
00:52the same time each night. But if you can't do that, then yes, having catch up sleep on
00:57the weekend has been agreed by a group of experts, it's agreed that that is probably
01:04going to be more beneficial than not catching up. The way you want to catch up though, ideally
01:09is still getting up at the same time each day in the morning, but going to bed a little
01:14bit earlier at nighttime rather than doing the sleep in. The problem with the sleep in
01:19is that it then means that you come bedtime that next night, you're less tired. So ideally,
01:27you want to be going to bed a little bit earlier to catch up on that sleep loss.
