A to Z Challenge: Z for Zeitgeber

The last letter of the alphabet! This was an interesting and challenging experience, as always, and I am so grateful for all the connections and comments. Thank you all for reading and encouraging me, and other caregivers.

Zeitgeber

I ran across this interesting word as I was studying a book called “The Paleo Approach” by Dr. Suzanne Ballantyne. Zeit means “time” in German and geber means “giver”. A “time giver” is “anything that influences your circadian clock”. Your circadian clock is all about your body’s routine. And routine is one of the most important tools of caregiving.

Examples of zeitgebers are the light and dark cycle, food intake and activity. Regular times for meals, for exercise and for sleep are beneficial to all of us, but especially for the very young, the elderly and for those with dementia. Being able to depend on a routine gives the impression that things are under control, and having any sense of control is comforting.

Routines

Routine is not the easiest thing for me as a caregiver. I am the queen of spontaneity, and will usually go out of my way to break up a routine. But now, I have things I do pretty regularly. One of the most important reasons I’ve developed routines is because they help me not to forget stuff I would otherwise probably forget. Routines also cut down on decision making because we have already decided what and when. And of importance, the routines help my husband know what to expect at various times of the day.

Circadian Rhythms and Sleep

The light/dark cycle is probably the most important zeitgeber, and the one I have the most trouble with. Being outdoors in sunlight during the day, and in the dark at night greatly affects circadian rhythm, which in turn affects the immune system, mental ability, mood, alertness and energy level. Ideally, the husband and I should get as much light exposure as possible during the day. We both should cut down on our screen time at night as well. Blue light from our computers, phones, TVs, and LED fixtures signals our bodies much like daylight does. It suppresses melatonin production. Blue light not only signals through the retina of our eyes, but even our skin has sensitivity to it. In contrast, low light and darkness signal the production of melatonin and bring on relaxation and sleep.

It is dark outside. Due to my circadian rhythms, I am getting sleepy. Take care of yourselves as we go through these strange times. Good night to all.

This evening Dennis, my husband, came out where I was sitting and apologized. Not knowing what he was apologizing for, we talked and I discovered he had read the X post. He was saying that he was sorry for making things hard for me. I was surprised that he had not read other posts this month, even though he was aware that I was writing on the subject of caregiving. He was sweet, and humbly aware of the impact that his illness has had on me and on our relationship. It’s moments like this that make me know that he is more than just my patient. He is still very much my husband.

Forty-seven years and counting…
