An insomnia expert has revealed the one tip she swears by to wake up energised even on dark mornings.
Dr Anna Joyce, a chartered psychologist and sleep therapist, says that when early daylight isn’t possible in the winter months, a consistent sleep schedule can help you feel awake – even in the dark.
“The most helpful tip is to keep a consistent wake time, even at weekends, to anchor the circadian rhythm,” explains Dr Joyce, who’s been researching sleep for 20 years.
The expert explains that the circadian rhythm is the “body’s biological clock.”
“It regulates functions throughout the day, including sleepiness and alertness, but also things like body temperature, hunger, physical and cognitive performance, and immune function,” she adds.
“Daylight as early as possible helps to support this anchor but this can be difficult during the winter.”
Dr Joyce – who runs her own insomnia clinic – says that our body clock is regulated by hormones: melatonin for sleep and cortisol for energy.
“By maintaining a consistent schedule, within about a half hour window, our body clock can predict what time to release these hormones to support us to feel alert or sleepy at about the right time each day,” she explains.
“Having a later schedule at weekends (or non-working days) mimics jetlag, making Mondays more difficult.
“There is also research showing that the consistency of sleep timing is even more important than sleep duration for long-term health.”
Aside from going to sleep and waking up at the same time everyday, Dr Joyce says there are some other ways you can survive the dark mornings.
“If people are up before dawn, then putting the lights on and starting the day with movement and something to eat also signal to the body that it is daytime.
“Although daylight is the strongest cue, movement and breakfast also help to anchor the circadian rhythm.
“Movement can be a workout or something more gentle like a walk or stretching.
“It’s also normal to feel groggy for around half an hour after waking up – it’s called sleep inertia.
“But if people are struggling beyond this in the absence of daylight, then it might be worth considering using a daylight lamp or visor to simulate daylight during the darker mornings.”
Lights bright enough to simulate sunlight can be prescribed for people who experience SAD – seasonal affective disorder.
It’s a type of seasonal depression that worsens in the winter due to the lack of sunlight.
“Visors are convenient because you can move around whilst wearing it rather than having to sit in front of a lamp,” Dr Joyce advises.
“Once it is light, then getting outside is still helpful.
“Contrast this by dimming the lights in the evening, as this cues the body to wind down for sleep.”
