8 Activities That Help Improve Sleep Hygiene
There are several activities throughout the day that can positively impact your sleep:
Mental tricks
Some people find that playing mental tricks can make them sleepy.
Try gently counting back from 100.
Or, if you prefer, reflect on the following three points based on the day’s events:
- Three things you enjoyed the most
- Three actions you performed well
- Three things you learned in the last 24 hours
This reflection activity will remind you that the day was valuable and contained positive events and memories.
Adequate sunlight exposure
Many of us work indoors in artificial light (especially in the winter) with limited sunlight exposure. And yet, “daylight is key to regulating daily sleep patterns” (Walker, 2018).
Try to get outside for at least 30 minutes each day to increase your time in natural light.
Smells and sounds
Try calming sounds and smells to see if they help you sleep and leave you feeling more rested in the morning.
When researchers played natural sounds such as a waterfall or gentle waves (known as pink noise) to sleeping participants, their sleep quality and learning improved (Ngo, Martinetz, Born, & Mölle, 2013).
Smells can also stimulate the brain overnight. Participants exposed to lavender while they slept experienced increased slow-wave sleep and reported feeling more invigorated on waking (Goel, Kim, & Lao, 2005).
Treating sleep apnea
Sleep apnea occurs when people have momentary pauses in their breathing during sleep. This can occur throughout the night, and if left untreated, can be linked to high blood pressure, memory loss, and even strokes (National Institute on Aging, 2020).
If you are experiencing tiredness during the day and snoring loudly at night, it is worth seeking help from a specialist.
Seeking help for sleep disorders
It’s useful to be aware of some more unusual behaviors humans exhibit during sleep, as they can affect sleep quality.
If you are experiencing any of the following (or other phenomena not mentioned) and it is damaging your sleep, it may be useful to seek expert advice (Lange, 2016):
- Sleep paralysis
During REM sleep, our body naturally becomes temporarily paralyzed to avoid excessive movement.
However, some individuals find that this paralysis can, terrifyingly, continue for a few moments when they wake, sometimes accompanied by pressure to the chest.
- Hypnagogic jerks
While not fully understood by science, it is not uncommon to twitch or experience a sense of falling as you drift into sleep. This often results in a sudden awakening. If it is only occasional, this is unlikely to need further attention.
- REM sleep disorder
Talking, shouting, or even hitting your partner during sleep can be upsetting and potentially harmful for you both. It can happen during bad dreams when the body has not been fully paralyzed.
- Exploding head syndrome (not as bad as it sounds)
This affects 1 in 10 of us from the age of 50. As we drop off, we hear a loud bang (like a gunshot) waking us up. It may be because of physical changes to the middle ear associated with aging.
Handling nightmares
Recurring nightmares or bad dreams can be very upsetting and are not uncommon. Indeed, 6% of adults describe having monthly nightmares (Centre for Clinical Interventions, 2020).
When woken by a disturbing dream, it’s difficult to return to sleep. If happening over a prolonged period, it can be harmful to your rest.
Pushing away the images is natural but unhelpful.
Imagery rescripting – closing our eyes and working through the images and narrative in our minds – can help us regain a sense of control by rewriting what happens. It could be (possibly with the help of a sleep therapist) that you rescript the end of a car chase into something less spectacular or with a different ending.
Overcoming insomnia
Insomnia is the medical term for persistent problems with sleep that can last for more than a month involving one or more of the following (Centre for Clinical Interventions, 2020):
- Difficulty getting asleep (onset insomnia)
- Waking during the night (middle insomnia)
- Poor sleep quality
While insomnia may begin in response to stress, pain, or other factors, negative thoughts about sleep can perpetuate the problem.
- Assuming the worst
Losing confidence in the ability to sleep
- Blaming everything on sleep
Blaming everything that goes wrong during the day on a lack of sleep
- Unrealistic expectations
Believing everyone has the same sleep pattern
- Unhelpful thinking styles
Catastrophizing, overgeneralizing, and black-and-white thinking can suggest sleep is always either ‘great’ or ‘awful.’
A Thought Diary can be a valuable tool for challenging negative thinking and inaccurate beliefs.
Sleep restriction
Cognitive-behavioral therapy for insomnia was developed to provide patients with a “bespoke set of techniques intended to break bad sleep habits and address anxieties” (Walker, 2018).
One of the surprisingly successful techniques for improving sleep quality is to restrict time spent in bed. By doing so, it encourages the patient to form a stronger connection between their time in it and sleep.
The aim is to limit the number of hours spent in bed to the typical number of hours asleep, known as the sleep window.
When we are sleeping poorly, we often spend too much time in bed, despite not being asleep. Restricting time can resynchronize natural sleep cycles.
Use the Sleep Restriction worksheet to calculate the sleep time needed.
Under increasing sleep pressure, the patient will, over time, gain more psychological confidence in “being able to self-generate and sustain healthy, rapid, and sound sleep, night after night” (Walker, 2018).
As that confidence increases, it will be possible to increase time in bed gradually.
