Wellness: Prioritize Sleep

(Nutrition, Exercise, Community)

No/Poor Sleep…

• …is a problem.

• The standard advice is to get more.

• But our culture doesn’t actually prioritize it.

Kirk Parsley, MD (TEDx)

• We pride ourselves on sleep deprivation

• We think we are immune

• We know performance suffers

Less Sleep & Health

1. Higher rates of heart disease, hypertension, dementia

2. Higher rates of sexual dysfunction

3. Higher rates of infection, allergy & asthma

4. Higher rates of depression, anxiety, anger, irritability, suicide

Less Sleep & Health

Virtually every body system or function is improved by sleep and detrimentally

affected by lack of sleep.

Evolution and Sleep

• Sleep would not appear to beneficial

• Necessities: food, water, avoiding predators and procreation

• The fact that sleep exists is a testament to how crucial it is

• It is only recently we have tried to ignore it

Sleep & Dementia

• Poor sleep may actually cause Alzheimer's Disease

• Glymphatic cells shrink during sleep and allow CSF to flush metabolic debris

• Purges the tau and beta amyloid proteins from the brain

Sleep & Heart Disease

• Poor sleep tips the sympathetic/parasympathetic balance to fight/flight

• More cortisol & adrenaline

• Less growth hormone

• Heart attacks and day light savings

• Increased in the spring (less sleep)

• Decreased in the fall (more sleep)

Sleep & Mental Illness

• Sleep is emotional first aid

• Lack of REM sleep contributes to mental illness

• Lack of REM sleep in adolescents is strongly associated with suicide

Dark Times

Death by Suicide-The EMS Profession Compared to the General PublicPrehosp Emerg Care. 2019 May-Jun;23(3): 340-32435.

CONCLUSION:In this statewide analysis, we found that EMTs had a significantly higher Mortality Odds Ratio due to suicide compared to non-EMTs. (5.2% vs 2.2%) (p = 0.0001)

Dark Times

• Police Executive Research Forum publication Oct 2019

• 9 suicides at NYPD in 2019

• 2 suicides in the Metro Nov 2019

Sleep & Diabetes

• Small studies restricting sleep:

• 4,5,6, hours/night for 1 week

• Insulin & blood sugar at pre-diabetic & diabetic levels

Sleep & Weight Loss

• No/poor sleep inhibits weight loss

• Muscle is preferentially lost instead of fat

Hunger Hormones

• Ghrelin- promotes hunger

• Increased with lack of sleep

• Leptin- inhibits hunger

• Reduced with lack of sleep

Growth Hormone (GH)

• The Repair hormone

• Released in response to:

• Deep sleep (slow wave sleep)

• High intensity exercise

• Fasting

Pilots have work hour restrictions.

Truckers have work hour restrictions.

ATCs have work hour restrictions.

Medical residents have work hour restrictions.

Public Safety has work hour restrictions.

Sleep Deprivation

• 18 hrs awake = performance at 0.05 BAL

• 24 hrs awake = performance at 0.08-0.1 BAL

Sleepy Driving• NTSB

• 100,000 highway crashes per year

• 71,000 injuries, 1500 deaths

• 20% of drivers report falling asleep behind the wheel

• NHTSA

• 1.2 million crashes per year

• 8000 deaths

Microsleep & Driving

• Falling asleep for seconds

• Drowsy driving causes more accidents than impaired driving

• Accidents are more lethal

Why do we Sleep?

Sleep Pressure & Circadian Rhythm

\

Sleep Cycles

• 5 stages

• 1,2,3,4

• REM- Rapid Eye Movement

• Repeating pattern in 90 min cycles

• 1,2,3,4,2,REM,2,3,4,2,REM,2,3,4,2,REM…

EEG Waves

Sleep Cycles

• Stage 1: occurs only once, a transition time

• Stage 2: >50% of sleep time, lighter sleep

• Stages 3 & 4: SWS, deeper sleep

• REM: 20% of sleep time

Stage 1

• Lasts 2-5 mins

• Least understood

• Quasi-REM

• “Hypnagogic state”

• Enlightening and inspirational

• Conscious and unconscious meld

Stage 2

• HR slows, body temp drops, unconsciousness

• Lighter sleep

• Important to prep your mind for learning

• Awaken relatively easily

Stages 3 & 4

• Slow Wave Sleep (SWS)

• Important to save memories

• Cortisol turns off, GH turns on

• Physical repairs

• Harder to wake up

REM

• Irregular, faster breathing, HR & BP rise

• Vivid dreams with paralysis

• Important for memory

• Mastering complex things

• Creativity

Caffeine Effects

• Blocks adenosine receptors in the brain

• Adenosine is usually inhibitory (downer)

• Fatigue/sleep pressure builds due to adenosine

Caffeine = Tool

• Good: Proven performance enhancer but effects are negated by tolerance.

• Bad: Long half life impairs sleep

• Make it a reliable tool

• Changing shifts

Energy Drinks

• The Up Sides…

Energy Drinks

• The Down Sides:

• Unknown ingredients

• Sugar

• Artificial sweeteners

• Caffeine tolerance

Use the Light

• Most powerful environmental/circadian cue

• Use light to your advantage

• Bright light early in your wake cycle

• Non-blue light before bed

• f.lux, Dark Mode, orange glasses

• Dashboard lights/work lighting

Sleep Hygiene• Consistent routine

• Sleep alarm

• Dark

• Sleep mask

• Cold

• 65 +/- degrees optimal

• Quiet

• Ear plugs or white noise

Sex & Snoring

• Your bed is for sleep or sex

• Program your body to happily anticipate going to bed

• Change your environment- sleep divorce?

• Get a sleep study if you snore

Emotional Commotion

• Guard your relationships

• Don’t check email before bed

• Prep your morning

• Keep a note pad by the bed

The Night Cap

• To relax…

• Messes with body cooling, HR, HRV

• Diuretic (waking up to pee)

Less Emotional Commotion

• Gratitude

• Practice awe

• Meditation/mindfulness

• Routines

• Tetris

Internal and External Wind Down

• External- cool down

• Decreased light

• Clock = Anxiety

• Eat & Exercise- >2-3 hrs before bed

Internal and External Wind Down

• Internal- meditation

• Journal “dump” with gratitude

• 50% less time to sleep

• Social Media & Email = Anxiety

• “Wired & Tired”

Anxiety disrupts Sleep

• Ephesians 4:26:

• “In your anger do not sin: Do not let the sun go down while you are still angry.”

• Maybe this is to protect your awake time, your relationships…

• …AND your sleep time.

Measure It

• When you don’t sleep well, figure out why

• Pay attention to your habits and activities

• Eating, sleep environment working out, alcohol, caffeine, screen time, etc.

Sleep Drugs

• All sleep drugs disrupt sleep architecture

• The best treatments for insomnia are behavioral

Insomnia is more often a Priority problem than a Physiologic problem

Treatment Priorities

1. Hygiene

2. Cognitive Behavioral Therapy for Insomnia (CBT-I)

Melatonin

• Questions:

• Timing

• Dose

• Dependence

• My take away: a reasonable option

To Nap or Not To Nap?

• Evolutionary evidence supports biphasic sleeping

• A longer period at night, shorter period 12 hrs later

• Lost with the invention of the clock and the industrial revolution

The 20 min Power Nap

• Stage 1: 2-5 mins

• Stage 2: the first Stage 2 takes 17 mins at minimum

• Increases alertness

• Avoids SWS and sleep inertia

Naps & Nocturnal Sleep

• Naps do not adversely effect nocturnal sleep if:

1. You have normal sleep

2. Shorter than 3 hours (max 2 sleep cycles)

3. Wake up >3 hours before bedtime

Sleep Inertia

• Waking from SWS

• You are not “more tired” than before

• Proven solutions:

1. Physical activity

2. Sensory stimulation

3. Caffeine
