Sleep

Determinants of Health #4 Sleep

Oh sweet sleep! This is such an important part of our mental and physical well-being that it gets a whole day to itself. Sleep needs change as we age, ranging from 12-18 hours when we are very little to 7-9 hours in adulthood. Many of my patients are chronically sleep deprived and they quickly learn that getting consistent, deep, restorative sleep can be life-changing!

Chronic sleep deprivation builds up over time. Studies show that getting less than 7 hours of sleep for 2 weeks leaves people functioning at the same level as if they had not slept for two days straight! And since our focus and alertness decline slowly, we may not even be aware of how poorly we are functioning.

Sleep is where the body heals and repairs itself, it literally washes the waste product out of your brain and is crucial for every system in the body. Mental focus, mood and the immune system are particularly affected by poor sleep (quality or quantity).

Another modern invention that disturbs good sleep is shift work. The WHO (world health organization) recognizes shift work as a known human carcinogen. This means working nights and sleeping during the day increases your risk for cancer. Scientists think this is because daytime sleeping does not result in the same production of melatonin, which acts as a powerful antioxidant in the body. There’s no way around it: humans are meant to sleep when it is dark outside. Disrupting that disturbs our internal clock.

Naturopathic doctors take a comprehensive look at your health. We ask about the many factors that influence health, which we term “The determinants of health.” Taking a patient-centered approach lets us build a comprehensive plan to help patients achieve their health goals.

Increased health risks due to loss of sleep

It's no surprise that we all need to sleep. But how exactly can losing sleep adversely affect our health? 

Here is some great information linking sleep deprivation with cancer, heart disease and Alzheimer's disease from a Guardian article by Rachel Cooke published on 9/24/17.

Chronic sleep deprivation is very common, with 2/3 of adults reporting getting less than the 8 hours a night recommended by the World Health Organization. Losing sleep can increase blood pressure, disrupt your body's metabolism and lead to weight gain. 

Sleep helps our brain unwind, store memories and release the events of the day. Adequate sleep leads to better mood and cognitive function. Far more seriously, sleep deprivation increases one's risk for Alzheimer's disease. 

Adults over 45 who get less than 6 hours of sleep a night face a 200% increased risk of having a stroke or heart attack in their lifetime. 

Sleep profoundly benefits the immune system. Sleep deprivation increases your risk for cold and flu. Also, after only one night of inadequate sleep (4-5 hours), the body's Natural Killer cells drop by up to 70%. Natural Killer cells are part of the body's natural mechanism and find and kill cancer cells. Lack of sleep is linked to breast, bowel and prostate cancer.  Furthermore, the World Health Organization considers any form of nighttime work to be possibly carcinogenic (meaning it can directly cause cancer).
