Understanding the Effects of Daylight Saving Time in Seniors
When you rely on a daily routine to navigate your day, any disruption to that routine can often lead to unnecessary stress. Thus, being aware of what to anticipate when Daylight Saving Time (DST) occurs is the most effective way to minimise potential challenges associated with the time change.
What Is Daylight Saving Time?
Daylight Saving Time (DST) is a seasonal adjustment of the clocks to make better use of daylight during the warmer months. New Zealand first implemented DST in 1927, but the practice has undergone various changes regarding its start and end dates over the years.
It was temporarily discontinued during World War II but reintroduced and standardised in 1975. The current schedule was established in 2007, extending the duration of DST by three weeks.
Effects of Daylight Saving Time in Seniors
The transition into or out of DST can disrupt the body’s natural circadian rhythms, leading to various challenges that are particularly pronounced in older adults.
Sleep disruption
One of the most immediate effects of DST on seniors is the disruption of sleep patterns. Research indicates that older adults are especially sensitive to changes in their sleep routines, which can lead to difficulties falling asleep or staying asleep after the time change. This disruption often results in increased daytime sleepiness, irritability, and a general sense of fatigue, exacerbating existing sleep-related issues such as insomnia or sleep apnoea.
Health risks
Disruptions in sleep patterns can disturb the body’s circadian rhythms, which are crucial for maintaining stable blood pressure levels. Normally, blood pressure dips during sleep, allowing the heart to recover from daily stress. When sleep is interrupted or insufficient, this nocturnal dip may not occur, leading to sustained elevated blood pressure. Over time, this can increase the risk of hypertension and other cardiovascular diseases.
Poor memory and concentration
The alteration in sleep can also affect cognitive functions. One may experience forgetfulness or confusion during the adjustment period, which is particularly concerning for those with cognitive impairments such as Alzheimer’s disease or dementia.
Disruptions in meal and medication schedules
Changes in routine can lead to missed meals or medications, which can adversely affect health. It is recommended to ask for help when it comes to sticking to usual schedules as closely as possible to mitigate these effects.
Coping with the Effects of Daylight Saving Time
The following are some tips to help you cope in the days and weeks when DST begins.
Adjust sleep schedule
Gradually shift your sleep schedule by 10-15 minutes in the days leading up to the time change. This gradual approach can help ease the transition and reduce the shock to their systems.
Keep daily routines consistent
Keeping daily routines consistent is crucial. This includes regular meal times, medication schedules, and social activities. A predictable routine can provide stability and comfort, helping to reduce confusion and anxiety during the transition.
Maximise natural light
Spend time outdoors during daylight hours. Exposure to natural light helps regulate circadian rhythms, which can improve mood and sleep quality.
Avoid caffeine
Caffeine is a central nervous system stimulant that can interfere with the ability to fall asleep and stay asleep. Consuming caffeine, especially in the afternoon or evening, can delay sleep onset and reduce overall sleep duration. As we get older, we may be more sensitive to caffeine’s effects due to age-related changes in metabolism and sleep patterns.
Another way to perform life adjustments brought on by daylight saving time is through professional help. Whether this means seeking a doctor for advice or looking into home care, it is always better not to meet these challenges alone.
