Sleep is such an important, yet overlooked and undervalued part of health. Especially for those of us with Type 1 diabetes. I make it a personal priority to get enough sleep – even with medical school and residency and as a T1D, I usually get 7-8 hours a night. It’s part of our collective consciousness in the diabetic community that having diabetes means accepting poor sleep as a reality – while this might be true some of the time, here are some things I do to ensure that I get good quality (and quantity!) of sleep most nights:

Avoid insulin on board at bedtime 

This rule dates back to when I was a pre-teen/teenager. My parents had a rule – no bolusing after 9pm! Now that I’m an adult, I’m a little more lenient with this rule, but the principle is solid. Avoiding food intake and insulin administration in the 2-3 hours before bedtime (even though now I usually am in bed before 10pm) helps decrease the number of variables that can interfere with your flat CGM line overnight (causing highs and rollercoasters), and also helps decrease the risk of overnight lows! This leads me to my next point:

Nail those nighttime basals

We spend approximately a third of our lives sleeping – this means that our overnight numbers are a HUGE contributor to our A1C, our Time-in-Range (TIR), and our overall health outcomes. Having the right basal rate (amount of background insulin to maintain steady BGs) to keep you steady and in range all night is crucial.

Understand what interferes with blood sugars during sleep

This is highly variable between individuals, and even within the same individuals over time. Some of us experience dawn phenomenon that spikes us overnight (which is due to Still, Things like heavy exercise or alcohol consumption Understanding how some of these factors work helps us be better prepared and equipped to address them!

Keep it general

Those are some of my diabetes-specific tips, but the importance of sleep hygiene and healthy sleep habits apply to us, too! And because  , these general habits are just as (if not more!) important for T1Ds than the general population! We do such a great job with bedtime routines and consistent bedtimes during childhood, because we know how important sleep is for health. Why give this up as an adult? Here are some tips I give all my patients, and try to follow myself, too:

  • Keep a consistent sleep schedule – choose when you need to wake up in the morning and commit to going asleep at least 7 hours before that
  • Start performing your bedtime routine about half an hour before bed – train your brain to get sleepy at the right time. Shut off that phone, brush your teeth, do some journaling, make a to-do list for the morning, read a book – whatever helps you wind down.
  • Don’t go to bed unless you are sleepy, and if you’re in bed lying there without falling asleep, get up and do something relaxing until you are sleepy enough to go back to bed.
  • Only use the bedroom for sleep! No TV, no eating.
  • Keep the bedroom cool! Studies show that optimum temperature for quality sleep is around 60-68 degrees Fahrenheit.
  • Avoid consuming caffeine in the afternoon or alcohol before bedtime – these can both interfere with sleep!
  • Exercise regularly for better sleep quality and ease of falling asleep, but
  • If you are concerned or have more questions about your sleep quality, ability to fall and stay asleep, unusual sleep patterns or excessive daytime sleepiness, see your doctor! They can help! 🙂
