Want to Prevent Cancer? Make Sure You Sleep Well

 

 

By Dr. Joseph Mercola

Many of us rush through our days and nights without taking the time to get a

good night’s sleep. Would you pay more attention to your sleep habits if they

could help to prevent cancer? Well, they certainly can, so if you feel you need

a good excuse to get some quality sleep, this is it.

 

 

 

How well you sleep can seriously alter the balance of hormones in your body.

This can then disrupt your sleep/wake cycle, also called the circadian rhythm. A

disrupted circadian rhythm may influence cancer progression through shifts in

hormones like melatonin, which the brain makes during sleep.

 

 

 

According to Brain Behavior Immunology October 2003, having a regular circadian

rhythm may be necessary in order for your body to defend against cancer, and

sleep/wake rhythms that are disrupted due to stress or other issues may promote

cancer growth.

 

 

 

Melatonin is an antioxidant that helps to suppress harmful free radicals in the

body and slows the production of estrogen, which can activate cancer. When your

circadian rhythm is disrupted, your body may produce less melatonin and

therefore may have less ability to fight cancer.

 

 

 

Exposure to light during the night can also reduce melatonin levels, which is

why it is important to sleep in total darkness to decrease the risk of cancer.

Another link between cancer and the disrupted circadian rhythm lies with a

hormone called cortisol, which normally reaches peak levels at dawn then

declines throughout the day. Cortisol is one of many hormones that help regulate

immune system activity, including the activity of a group of immune cells called

natural-killer cells that help the body battle cancer.

 

 

 

Yet another mechanism that may be related to the cancer/sleep association is the

hormone insulin. University of Chicago researchers have repeatedly shown that

insufficient sleep will result in an increased rate of diabetes due to increased

insulin resistance, and insulin has been clearly linked to cancer in previous

studies.

 

 

 

We all know that sleep is important. The research is quite clear that

insufficient rest will result in increased rates of cancer and diabetes, while

optimizing your sleep can slow down the aging process. If you need some help

getting a good night’s sleep, you can review the sleep guidelines that seem to

help many of our patients.

 

 

 

I recently attended a conference with Dr. Deepak Chopra and thought that many

could also benefit from the following tips from his Insomnia Protocol:

 

 

 

 

The natural human biorhythm is to sleep between 10 p.m. and 6 a.m. This means

you should be in bed, with the lights out, by 10 p.m. and be up by 6 a.m. If

this is difficult for you, keep in mind that people naturally followed this

pattern before the advent of electricity. When the time switches in two weeks

ideally you should be in bed by 9 PM since this is equal to 10 PM prior to the

time switch.

 

 

Decrease your mental activity after dinner. Journaling may help in this process

by allowing you to put your anxieties on paper and get them out of your mind.

 

 

Make preparations for the next day, such as determining what you’d like to

accomplish, so you don’t have to think about it.

 

 

Take a hot bath for up to an hour with calming fragrances (lavender, vanilla,

sandalwood) 30 minutes before bedtime. Use the bath to let go of your daily

stress, include soothing lights and music and massage your body with oils.

 

 

Use your bed for sleep and sex only. Even reading should be done elsewhere,

unless it has a calming effect, such as spiritual literature.

 

 

Turn all lights off. Lie on your back and focus on they way your body feels

(your mind-body awareness) and on your breathing.

 

 

Try reciting a mantra for five minutes. This could be some sort of favorite

sound or prayer that you recite continuously.

 

 

 

Something warm, like a hot water bottle, may help soothe your anxieties,

especially when placed between the navel and bottom of rib cage.

 

 

If you wake during the night, try repeating some of the techniques above or

massaging your head or feet.

 

 

If you find it difficult to sleep in your bed, pick another area of the house to

sleep in.
