Full disclosure: I was not always the highly effective sleeper that I proclaim to be
today. In fact, I would often force myself to stay up as late as I could – often
resulting in less than 5 hours of sleep a night. Mornings were usually spent
waking up to an obnoxious alarm clock, rushing around to get ready and finally
get out the door. I always woke up feeling sluggish and had to rely on artificial
energy from coffee and soda just to get me through the day.
Does this sound familiar? If so, I am here to tell you that it is possible to take
control of your sleep schedule and wake up feeling energized and ready to tackle
the day with major go-getter vibes! Implementing good sleep hygiene in my life
has not only been good for my health – it has been life changing. Sleep is really
the linchpin of wellness. It’s important for immune health, hormone health, brain
health, and metabolic health. Even with dietary and lifestyle changes – nothing
will work effectively without proper sleep!
What is sleep?
I always used to think of sleep as some random, dormant, inactive state that
everyone does to some degree or another for reasons unknown. Now I realize
it’s a bit more complex than that – our bodies are actually active during sleep with
many important functions happening. Our bodies progress in and out of 5 stages
in cyclical fashion while we are in an unconscious state. It takes adequate sleep
(without interruption) to perform all five of these functions, which are necessary to
achieve optimal health. This is why quality sleep is just as important as quantity.
How does sleep work?
Our sleep/wake cycle is driven by our circadian rhythm, a 24-hour cycle of
biological processes controlled by our brain. There is a terminology used to
describe our sleep regulation called “sleep pressure” and “wake drive”,
developed by sleep researcher, Dan Pardi, MS. The first, sleep pressure, starts
to build the moment we wake up and accumulates throughout the day. As sleep
pressure builds, we become tired. The second, wake drive, produces our
alertness and wakefulness in contrast to sleep pressure. During the day, our
wake drive increases and keeps our energy levels stable.
What happens while we sleep?
Not only does our body engage in a restorative process of tissue repair and
regeneration while we sleep but our brains literally drain out the toxins we’ve
accumulated throughout the day. The process is called the glymphatic system. You can think of it as sort of a plumbing system for your brain. The space between our brain cells increase during sleep, allowing our brain to flush out toxins that have built up during our waking hours. It’s evident that sleep is crucial for enhancing our memory, mental clarity, improving our energy levels, managing stress, and keeping us happy!
So, what’s the secret to a good night’s sleep? If only it were as simple as
counting sheep. To help make falling – and hopefully staying – asleep a little
smoother, I’ve put together a list of sleep hygiene habits that I personally use
myself or have recommended to clients. Remember, we are all bio-individual so
you will have to explore which ones work best for you!
1. Keep a consistent schedule. Try to go to bed and wake up about the same
time each day. Opt for 7-9 hours (or more) of quality sleep a night.
2. Create bedtime rituals. I like to take a hot bath with some Epson salts before
bed or do some reading. I also like to make lists of things I want to accomplish
the next day. I find that writing things down is a good approach to clear out my
“mental desktop”. This allows me to relax more and not think about all the stuff I
need to get done the next day.
3. Kill the lights. As soon as the sun goes down I like to dim most of the lights in
my house or use candles instead of artificial light. Melatonin kicks in a few hours
before bedtime and I find that dimming lights helps to jumpstart that process.
Keep in mind that light from screens like TV’s, iPad’s, and cell phones is a big
trigger for neurotransmitters to keep you “on” resulting in poor sleep. If I have to
use my phone or laptop at night I wear blue-light blocking glasses. Ideally I like to
eliminate screen time before bed. I recommend getting a pair if you tend to be in
front of screens after dark.
4. Get some exercise. We should be moving our bodies as much as possible
throughout the day. Little movements like taking the stairs instead of the elevator
or parking a good distance from an entrance add up and result in better sleep.
Even a 10-15 minute walk is beneficial for sleep hygiene. Just be sure to avoid
anything too intense like running, cycling or biking a few hours before bed.
5. Avoid alcohol and caffeine. To achieve a sound and restful sleep these things
must be avoided. Alcohol causes dehydration and blood sugar crashes, which
disrupt sleep. Caffeine stimulates cortisol – the “wake up” hormone. At the very
least, try to avoid these things a few hours before bed.
6. Make your bedroom comfortable. Your environment should be cozy and
conducive to sleep. Your bed should be clean with comfortable sheets and
pillows and your room should be very dark and cool. Consider investing in black out shades for your windows. The less light creeping into your bedroom, the deeper you’ll sleep. Ideally you should keep all electronics out of the bedroom.
7. Eat well. This may seem obvious to those reading but eating well really does
impact your sleep – in the best way! Try to avoid greasy food, spicy food and
sugar before bed. Aim to include some starchy carbohydrates like sweet potato
or squash and healthy fats into your diet at dinnertime. Leave a few hours
window between your last meal and bedtime. I also like to stop drinking anything
2-3 hours before bed. Most people sleep best when their stomach is neither too
full nor too empty and their bladder is completely empty!
8. Practice self-care. Wash your face, brush your teeth, and moisturize your skin.
Change into comfortable clothing and prepare your outfit and items for the next
day. Keep a clean and organized home free from clutter.
9. Practice mindfulness. Engage in a “body scan.” To do this start by laying in
your bed and tense and release each part of your body starting with your toes
and ending at your head. Focus on your breath, your environment, and body
sensations in the moments before you drift off to sleep.
