It’s almost that time of year again—time to change the clocks!
The springtime change has a hopeful element to it; the days get longer and you have more daylight to enjoy in the evening hours. It almost feels like you can measure the increased daylight every day! It signals that spring is truly on its way.
There is one big challenge first though. That’s the loss of one hour! For most of us, that means the loss of an hour of sleep.
It would seem as though losing one hour of sleep shouldn’t be that detrimental. Surely we can handle one less hour of sleep. And yet, statistics indicate that losing one hour of sleep does impact us, and not for the better. It’s a well-known fact that there is a higher incident rate of automobile collisions on the Monday following the spring time change. Some studies have indicated an increased risk of heart attack too!
If losing one hour of sleep can cause us to drive poorly and increase our risk of heart attack, what does it do for someone with dementia who may not understand what is happening with the time change?
Adjusting to the time change is essentially like dealing with jet lag. While it is only a one-hour difference, it is enough to throw us out of whack for a few days as we slowly adjust. Our bodies are finely tuned mechanisms that follow a very careful circadian rhythm. When that rhythm is interrupted, it takes us a while to get back on track. If that much adjustment is needed for those of us who can cognitively understand the time change, how much more difficult is it for someone with dementia who cannot tell time?
Someone with advanced dementia may not be able to tell time anymore. Some days, it may seem as if they don’t have much routine if they are waking at odd hours and sleeping during the day. But even if their routine has shifted from what it was years ago, they still have an internal sense of the passing of time. Suddenly missing an hour throws off that internal sense, and it can feel disorienting and confusing.
Sleep is critical for brain functioning in all people, and especially so for those with dementia. The brain needs a chance to recover and it is during sleep that memory is encoded. When someone’s brain is impacted by a disease that impairs memory, they may require extra sleep to encode even minimal memory. Sleep is essential, and losing an hour of sleep can have an enormous impact on how someone functions.
As much as possible, try to adjust bedtime and waking time in advance of the time change to make it a more gradual adjustment rather than a one-hour change overnight. On the eve of the time change and the subsequent nights, ensure that your loved one still receives their usual allotment of sleep, even if it means going to bed a bit earlier or getting up a bit later.
When caring for someone with moderate or advanced dementia, just knowing what to expect can make a difference. Recognize that the time change is just like dealing with jet lag and it will be an adjustment for your loved one. Expect that they may exhibit some unusual behaviour or feel agitated and anxious the week following the time change.
Prepare as much as possible by making the adjustment gradual. And remember, these adjustments will be helpful not only for your loved one but also for you!
