Extra Hour of Sleep Ahead: How Daylight Saving Time Affects Mental Health
As the weekend approaches, many will relish the chance to snuggle into their warm beds for an additional hour of sleep thanks to the transition back into standard time. On Sunday, October 27, at 2 a.m., clocks will fall back one hour, marking the end of Daylight Saving Time. However, while most may celebrate an extra hour of slumber, experts warn that this time shift can greatly affect our daily rhythms, mood, and overall mental health.
The Science Behind the Time Change
The adjustment to standard time disrupts our circadian rhythms—our body’s internal clock regulated by light exposure. According to Theresa Schnorbach, a sleep scientist at Emma, the suprachiasmatic nucleus (SCN) plays a crucial role in this process. “This means that any change to our light exposure can disrupt our sleep-wake cycle, which can physically affect us by impacting the regulation of our core body temperature and blood pressure.”
The onset of fewer daylight hours can exacerbate mental health issues too. Antonio Kalentzis, a psychologist and British Psychological Society committee member, emphasizes that decreased sunlight can worsen symptoms of Seasonal Affective Disorder (SAD). Those susceptible to mood disorders may experience heightened anxiety and depressive symptoms during this transition.
Cognitive and Physical Impacts
The transition doesn’t only impact mood—it can also challenge cognitive functions. Kalentzis points out that disturbances in sleep can impair attention, memory, and problem-solving abilities. “Sleep deprivation from the time change can lead to increased accidents and decreased performance in various daily activities,” he explains.
Preparing for the Time Change
To mitigate the adverse effects of the time change, experts recommend several strategies to help individuals prepare their minds and bodies:
-
Gradually Adjust Your Sleep Schedule: Start by shifting your bedtime by 15-30 minutes earlier each night leading up to the time change. If your typical bedtime is 11 p.m., try going to bed at 10:45 p.m. for a few nights, then 10:30 p.m.
-
Avoid Napping: Avoid naps when possible, especially close to bedtime. Schnorbach states, “Taking naps throughout the day reduces the levels of adenosine, a key chemical that makes you feel sleepy at night.”
-
Adjust Your Meal Times: According to Dr. Lindsay Browning, a psychologist and sleep expert, moving meals slightly later in the day can also help your internal clock acclimatize.
-
Change Your Light Bulbs: To improve sleep quality, Schnorbach suggests using warmer-colored or red light bulbs in the hours before bedtime, as these can positively influence melatonin levels.
-
Limit Afternoon Caffeine: “Avoid caffeine after about 2 p.m.,” Browning advises, as caffeine can linger in the system and disrupt sleep.
-
Maximize Exposure to Natural Light: Especially in the morning, light exposure is crucial for regulating circadian rhythms and improving mood and cognitive function.
-
Avoid Bright Lights in the Evening: Engaging in good sleep hygiene means limiting screen time in the hours leading up to bed to prevent disruptions in melatonin production.
-
Stay Social: Engaging in social activities can help combat feelings of isolation as daylight decreases, notes Kalentzis, emphasizing the importance of a supportive network for mental wellbeing.
- Incorporate Relaxation Techniques: Mindfulness practices such as meditation and yoga can enhance emotional regulation and reduce anxiety.
The Bigger Picture
While the extra hour of sleep might seem enticing, the implications of the time change extend beyond just feeling sleepy. It is essential to recognize the potential mental health challenges that arise during this transition. As people adjust to the shifting light conditions, proactively engaging in strategies to bolster mental wellness can make all the difference.
