Understanding Circadian Rhythm and Sleep Hygiene
Consistency in waking up time is crucial to strengthen the circadian rhythm, with minor variations of no more than an hour. Exposure to sunlight, ideally within the first hour after waking, and moderate exercise in the morning actively reinforce the circadian rhythm. Following a consistent schedule and good sleep preparation practices significantly contribute to improved sleep quality.
Dealing with Jet Lag through Circadian Adaptation
Jet lag falls into the category of extrinsic circadian rhythm disorders, where travel disrupts the synchronization between an individual's internal clock and the destination time zone. Strategies to reduce jet lag include partially adapting to the destination time zone before travel and adapting quickly upon arrival by exposing yourself to sunlight, timing meals conventionally, and engaging in circadian-aligned activities.
Effects of Traveling West and East on Circadian Rhythm
Traveling westward tends to be more tolerable as it aligns better with staying awake longer, whereas traveling eastward can be more challenging as it involves attempting to sleep earlier than usual. Strategies for eastward travel include staying awake during the flight and adapting to local time on arrival to facilitate circadian adjustment.
The Significance of Sunlight and Exercise for Circadian Health
Sunlight exposure within the first hour after waking, alongside moderate morning exercise, plays a critical role in strengthening the circadian rhythm and promoting a healthy waking-sleep cycle. Consistent exposure to morning sunlight and physical activity contribute to setting the body's internal clock and improving overall sleep patterns.
Effect of Light Exposure on Sleep Patterns
Exposure to bright lights at nighttime disrupts the circadian rhythm, affecting shift workers and potentially impacting individuals' sleep quality. Research suggests that intense light exposure during the daytime, mimicking sunlight, can have a positive influence on sleep-wake cycles.
Importance of Proper Lighting in Critical Environments
Bright lights, such as those found in intensive care units, can be detrimental to both shift workers and patients, leading to sleep disturbances and potential circadian rhythm disruptions. Utilizing appropriate lighting strategies, such as positioning lights closer to the eyes or using specialized lamps, can help mitigate these negative effects.
Preparation for Sleep: Tips for Wind-Down Routine
Preparing for sleep involves mindful consumption of substances like caffeine and nicotine, as well as establishing a calming wind-down routine. Avoiding stimulating activities such as checking emails before bed and ensuring a stress-free environment can contribute to a more restful night's sleep.
Incorporating Sleep Journaling for Better Sleep
Participating in sleep journaling, where individuals write down their thoughts and worries a few hours before bed, can help compartmentalize concerns and promote better sleep quality. By acknowledging and scheduling dedicated worry time, individuals may find it easier to relax and prevent intrusive thoughts from disrupting their sleep.
I’m always on the search for better sleep. I’ve tried supplements, better pillows, meditations but there always appears to be a day or 2 in my week where I don’t sleep well. And on the one hand, I was pleased to find out that that’s about average and that’s not particularly abnormal, but I still want better sleep.
Today, Dr David Garley is on the podcast, he works as a GP in Bristol and is director of The Better Sleep Clinic. He treats a wide range of sleep disorders, mainly working with insomnia and obstructive sleep apnea and sees first hand the impact that poor sleep can have on physical and mental health. But he also started his medical career in respiratory medicine, that we get into at the start of the podcast.
We talk about:
Warning signs of poor sleep and its detriment to lifespan
The systems that control sleep
How we can manage jet-lag
The effect of light on circadian rhythm
What to do when you can’t sleep
Whether sleep supplements are worth it
And if there is a diet for sleep?
