<\/p>\n

Sleep is essential to health. Adults need 7-9 hours of restorative sleep. But it\u2019s not enough to just sleep eight hours. Quality<\/em> of sleep is important as well.<\/p>\n

What sleep does to restore us is based on our response to stress and our autonomic nervous system<\/strong>. This system is about the balance of our sympathetic<\/strong> and parasympathetic<\/strong> systems. Sympathetic<\/strong> provides our fight or flight response. This elevates our heart rate, our blood pressure and the stress hormone cortisol, so we can get out of danger. The parasympathetic<\/strong> is our rest and digest system. This system lowers blood pressure, heart rate and mobilizes our gut. Both systems should be equal and active to keep us in balance.\u00a0 Sleep is our part of our parasympathetic and recharge system. <\/strong><\/p>\n

1 \u2013 <\/strong>Detoxification<\/strong>:<\/p>\n

Our brain detoxifies while we sleep by sweeping up all the toxins from the chemical reactions in our brain. Glutathione is an antioxidant in our body made in the liver. Decreased sleep leads to decreased glutathione, which leads to chronic illness.<\/p>\n

2 –Hormone balance:<\/strong><\/p>\n

Sleep debt results in decreased growth hormone. This hormone grows bones, and helps heal our injuries. Sleep debt affects our body\u2019s ability to grow and heal.<\/p>\n

3 –Glucose control and (4) Control of blood pressure:<\/strong><\/p>\n

Cortisol is our stress hormone. Some stress is actually good for our body. We need some cortisol to get us out of danger — as in fight or flight. However, persistent elevation of cortisol is a problem.\u00a0 When we stress our bodies with poor sleep, our bodies maintain high cortisol levels. Cortisol also serves as our wake up hormone.\u00a0 It peaks in the morning and goes down as the day goes on. When we do not get adequate, quality sleep, cortisol levels go up at night, which actually causes our sleep habits to worsen. Poor sleep leads to more poor sleep, keeping cortisol levels from changing as they should. Sustained, increased levels of cortisol cause elevation in our morning glucose, as well as elevation in our blood pressure, which can increase our cardiovascular risk for heart attacks and strokes.<\/p>\n

5 –Weight management<\/strong>:<\/p>\n

Leptin and ghrelin control our hunger and satiety. Both hormones are disturbed by lack of sleep. This means that we are hungrier<\/strong> with less satiety when we don\u2019t sleep. As a result, we crave foods that are not healthy for us, like high sugar foods. This directly impacts our weight control.<\/p>\n

6 \u2013 Memory:<\/strong><\/p>\n

Neural pathways to our memory center are directly impacted by sleep disturbance, causing poor memory storage. When we are stressed, cortisol levels are higher. Higher cortisol levels lead to trouble sleeping. Poor sleep results in decreased ability to retain memory.<\/p>\n

7 –Risk for certain cancers:<\/strong><\/p>\n

Studies have shown that darkness when we sleep induces the hormone melatonin, which normally peaks at night. Melatonin can protect us from certain cancers. Melatonin is suppressed when we look at our phones or tablets or are working in bright lights.<\/p>\n

8 \u2013Manage Immune System:<\/strong><\/p>\n

Sleep disturbance can lead to a suppression of our immune system, which is why we tend to get colds more quickly when we don\u2019t sleep.<\/p>\n

9\u2014Performance:<\/strong><\/p>\n

Studies have proven that even a decrease in sleep for one night by approximately 1.5 hours can lead to a decrease in alertness and performance the next day. Leave the task and work on it in the morning.<\/p>\n

10 — Improved energy:<\/strong><\/p>\n

Restorative sleep leads to a refreshed state. We charge our battery and reinforce the \u2018rest and digest\u2019 part of the system.<\/p>\n
