Can you wake most mornings w/o an alarm clock when you need to? Can you get through most days w/o feeling drowsy? Can you read the newspaper or sit through a lecture w/o dozing? Can you go through the day w/o being irritable or distracted?
Why is sleep so important and what happens when we don’t get enough. 40% adults that effects their day time activities a few days each month. Most sleep orders are un diagnosed or untreated.
Greatest Number of Accidents occur between 2-6 am and 2-4pm (2 sleepiness peak times in our biological rhythm) Risk of an accident from excessive sleepiness is only tip of the iceberg….what about the effect on our body/our physical and mental health? We will look at this more in a minute, but first let’s talk about what sleep does for us!
Stage 2: Longest phase and phase where many older adults and chronically ill spend most of time.
So if we are not spending enough time in these critical stages, what effect does that have on our health? Let’s look at a couple different systems… Heart: Harvard Nurses Health Study of 70,000 women found women who only slept 6 hours/night had 18% greater risk of MI. Not getting enough growth hormone produced for muscle endurance could weaken heart?? Immune System: Several studies have found a 50% reduction in lymphocytes or WBC after 4 hours of sleep. Think about the times you become sick? Were you lacking sleep few days prior? Depression and other psychological problems: Problems with sleeping can cause problems in dealing with stress, completing projects, and controlling moods (balance of neurotransmitters). Studies have found treating insomnia can decrease depression. Endocrine System: Hormone imbalance caused by sleep deprivation may cause obesity. Less sleep causes low levels of leptin (hormone that suppresses appetite) Less sleep also causes higher levels of ghrelin (stimulates appetite)
The result! So what can we do to make sure we get a good night of sleep? Let’s start with some of the problems…
Inactivity, overeating and indigestion, alcohol, nicotine, caffeine Overstimulation, erratic schedules, Overextension Bedroom mistakes: temperature, light, noise, clutter, pets, bed, space, spouse
If we are lucky, we will spend half of our life sleeping. The other 2/3 of our life are affected by the quality of sleep. Psychologists and Scientists have shown sleep can be directly & indirectly tied to abnormalities in different systems. So what can we do to improve our sleep quality?....
Everyone is different… Myth …the need for sleep doesn’t decline with age but the ability to sleep six to eight hours at one time may be reduced.
