New study finds optimistic people sleep better and longer.

Wednesday, August 14th, 2019

A new study published in the journal Behavioral Medicine concluded that young and middle aged adults who are most optimistic tend to be better sleepers. Over 3,500 subjects age 32 to 51 from 4 major cities in the USA were included in the sample. In the study optimism was measured using a 10-item survey which asked them to rate on a 5 point scale how much they agreed with positive statements such as “I’m always optimistic about my future” and included negatively worded sentences such as “I hardly expect things to go my way.” Scores on the survey questionaire ranged from six (least optimistic) to 30 (most optimistic). Subjects completed the survey two times  five years apart. Questions included overall sleep quality and duration during the past month, symptoms of insomnia, difficulty falling asleep,and the number of hours of actual sleep they obtained. A subset of the study  wore activity monitors for three consecutive nights including two week nights and one weekend night. The monitors were worn two time one year apart.

Researchers reported “Results from the study revealed a significant associations between optimism and various characteristics of self reported sleep  after adjusting for a wide range of variables, including socio-demographic characteristics, health conditions and depressive symptoms.”  They found that with each standard deviation increase regarding optimism scores there was a 78% higher odds of reporting very good sleep quality. In addition, those who had greater levels of optimism were more likely to report they got adequate sleep usually six to nine hours nightly and were also 74% more likely to report no symptoms of insomnia and to report less daytime sleepiness. A 2016 study found that about 1/3 of adults in the USA fail to get adequate sleep increasing their risk of chronic illnesses. Researchers stated “The lack of healthy sleep is a public health concern, as poor sleep quality is associated with multiple problems, including higher risks of obesity, hypertension and all cause mortality.” “Dispositional optimism–the belief that positive things will occur in the future-has emerged as a psychological asset of particular salience for disease-free survival and superior health.” These findings bolster previous findings of the researchers in which they found optimists ages 45 to 84 were twice as likely to have ideal heart health than those will least optimism.

Irregular Sleep Patterns associated with several Metabolic Disorders

Wednesday, June 19th, 2019

A new study in Diabetic Care reported that not following a regular bedtime and wake up schedule and getting different amounts of sleep each night can put people at higher risks for obesity, high cholesterol, hypertension, high blood sugar, and other metabolic disorders. In fact, they found that for every hour of variation in bed time and time asleep, a person can have up to a 27% greater chance of experiencing a metabolic abnormality. Past studies have shown a link between insufficient sleep and metabilic disorders but had not evaluated the factor of irregular sleep and disorders. This research showed that even after considering the amount of sleep a person gets and other lifestyle factors, everyt one hour night to night difference in bed time or the duration of a nights sleep multiplies the adverse metabolic effect.

In this study researchers followed 2003 men and women, ages 45 to 84, participating in the NHLBl-funded Multi-Ethnic Srtudy of Atherosclerosis. Subjects were followed for a median of 6 years to evaluate the relatiopnship between sleep regularity and metabolivc effects. Subjects wore actigraph wrist ewatches to closely tract sleep schedules and to provide objectivity for seven consecutive days.  They also kept a sleep  diary and responded to standard questionaires about sleep habits and other lifestyle and health factors. The actigraphic tracking took place between 2010 and 2013 and subjects were followed to 2016-2017. Results showed the variations in sleep duration and bedtimes preceded the development of metaboliv disorders and provides some evidence supporting a causal link between iurregular sleep and metabolic disfunction.  Other findings include that participants whose sleep varied more than one hour were more likely to be African-American, work non-day shift schedules, smoked, and had shorter sleep duration.  This group also had higher rates of depression symptoms, total caloric intake, and index of sleep apnea.  Researchers said that increasing sleep duration or bedtime variation was strongly associated with multiple metabolic and simultaneous problems such as lower HDL cholesterol. and higher waist circumference, blood pressure,  total triglycerides, and fasting glucose. In summary, maintaining as regular sleep schedule has beneficial metabolic effects.

My Guest, Dr Leigh Erin Connealy. M.D. will discuss her new book: The Cancer Revolution A Groundbreaking Program to Reverse and Prevent Cancer

Every year, over 1.5 million people in the US are diagnosed with cancer. Nearly everyone has been touched by this disease—be it their own diagnosis or that of a family member or friend. When faced with the news they have cancer, people start searching for safe and effective treatments. In The Cancer Revolution: A Groundbreaking Program to Reverse and Prevent Cancer, Dr. Leigh Erin Connealy shares integrative medicine techniques, lifestyle approaches, and wellness plans for cancer patients.

Dr. Connealy suggests that it’s not enough to undergo traditional treatments alone. Drawing upon the homeopathic, nutritional, bioenergetics, regenerative, and antiaging disciplines, The Cancer Revolution offers six “Revolutionary Cancer Strategies” to provide better management of cancer, including:

        Let  Food Be Your Medicine ·       Get Moving to Get Well
        Remove Toxins to Boost Your Health ·       Reduce Stress and Reclaim Your Life
·       Harness the Power of Supplements ·       Strengthen Your Immune System with Sleep

By detoxifying, protecting, and providing nutrients to our bodies, Dr. Connealy suggests that we can all lead longer, higher quality lives—even when faced with this formidable disease. She also highlights how these practices can reduce your risk of getting cancer in the first place.

Leigh Erin Connealy, MD, attended the University of Texas School of Public Health and graduated from the University of Health Sciences Chicago Medical School. Her post-graduate training was completed at the Harbor/UCLA Medical Center in Los Angeles. She is the founder and medical director of the Center for New Medicine and the Cancer Center for Healing in Irvine, California. One of the foremost integrative medical doctors in the country, she has been treating patients for nearly thirty years.

Can Weight and Diet Predict Sleep Quality:

Wednesday, June 15th, 2016

 

Holistic-Health-Show-with-Dr-Carl-O-HelvieA new study presented at the American Professional Sleep Society this week in Denver concluded that an individual’s body composition and caloric intake can influence time spent in specific sleep stages . In the study 36 healthy adults spent two consecutive nights in bed for 10 hours at the hospital at the U of Pennsylvania. Physiological changes that occur during sleep was recorded on the second night on a Polysomnograph. Body composition and resting energy expenditures were assessed in the morning following the first night of sleep and food/drink intake were measured and recorded each day.

Results showed that body mass index (BMI), body fat percentage and resting energy expenditures were not significant predictors of sleep stage duration. However, overweight adults exhibited a higher percentage  of time spent in the rapid-eye movement (REM) stage of sleep than normal-weight adults.  REM sleep stage  is when dreams typically occur and is characterized by a faster heart rate and breathing and less restorative sleeping  than in non-REN stages. They also found that increased protein intake predicted less stage 2 sleep and predicted more REM sleep. Stage 2 sleep is the period when a person’s  heart rate and breathing are relatively normal and his/her body temperature is slightly lower. Researchers said further research is needed to determine whether changing protein intake alters REM sleep duration and to find the biologicval mechanism behind this relationship.

Can Sleep Influence Survival of Breast Cancer Patients?

Friday, May 9th, 2014

logo1267406_mdA recent study reported in the journal  Sleep concluded that sleep efficiency, a ratio of time asleep to time spent in bed can predict survival time for women with advanced breast cancer. Results showed that higher sleep efficiency was significantly associated with lower mortality over the next six years even after adjusting for baseline prognosis factors such as age, estrogen receptor status, and treatment received. The mean survival was 68.9 months for efficient sleepers compared to 33.2 months for those with poor sleep efficiency. In addition, a 10% increase in sleep efficiency reduced the estimated hazard of subsequent mortality by 32 percent. There was no association between sleep duration and survival.

The study included 97 women with breast cancer who had a mean age of 55 years and objective sleep parameters were measured by wrist actigraphy for three consecutive nights . Overall subjects spent about 8 hours in bed but sleep for only about 6.5 hours. Authors said that although the mechanism of the relationship between sleep quality and advanced breast cancer survival is unknown , they suspect that sleep disruptions may lead to diminished immune function or impaired hormonal stress, responses that are more directly responsible for the decreased survival. More research is needed to develop and test intervent0ons adapted to cancer patients and survivors.

Can Mindfulness-based Meditation Help Teens with Cancer?

Wednesday, March 19th, 2014

logo1267406_mdA new study presented at the American Psychosomatic Meeting in San Francisco this month concluded that mindfulness-based meditation could lessen some symptoms associated with cancer for teenagers. Researchers asked  13 teenagers with cancer to complete questionaires covering mood (positive and negative emotions, anxiety and depression), sleep and quality of life. The group was divided into two  and one group the research group was given eight mindfulness-based meditation sessions asnd the other group of five were put on a wait ;ist. The eight sessions were 90 minutes long and took place weekly. After the eight week session both groups filled out the same questionaire a second time . Researchers said “We analyzed differences in mood, sleep and quality of life scores for each participant and then between each group to evaluate if mindfulness sessions had a greater impact than the passage of time only. Findings showed that teens participating in the mindfulness sessions had lower scores on depression after 8 weeks and girls from this group reported sleeping better. Researchers also found that girls developed mindfulness skills better than boys. Researchers concluded that “Our results suggest that mindfulness sessions could be helpful in improving mood and sleep in teenagers with cancer, as previous oncology research suggests with adults.” However, results were not large enough to make definitive conclusions.

Can Sleep Deprivation Increase Risk of Aggressive Breast Cancer?

Friday, September 7th, 2012

A new study published in  Breast Cancer Research and Treatment concluded that lack of sleep is linked to more aggressive breast cancer and the likelihood of recurrence.  Four hundred twelve post-menopausal breast cancer patients were recruited at diagnosis and asked about the average sleep duration over the past two years. Their likelihood of recurrence was measured by the Oncotype Dx test that assigns a tumor recurrence score for the individual based upon the expression level of a combination of 21 genes. Results showed that women who reported six hours or less sleep each night on average before breast cancer diagnosis had higher Oncotype tumor recurrence scores. The researchers said “This is the first study to suggest that women who routinely sleep fewer hours may develop more aggressive breast cancer compared to women who sleep longer hours.” “We found a strong correlation between fewer hours of sleep per night and worse recurrence scores, specifically in post-menopausal breast cancer patients. This suggests that lack of sufficient sleep may cause more aggressive tumors, but more research will need to be done to verify this finding and understand the cause of the association.”

Risk Factor for Colon Cancer Includes Lack of Sleep

Wednesday, February 16th, 2011

Recent research published in the journal, Cancer, concluded that individuals who average less than six hours of sleep a night have a 50 percent greater probability of colorectal adenomas, precursors to cancer, than those who slept seven or more hours nightly. The researchers believe this is the first study to report on sleep duration and colorectal adenomas.

Telephone interviews were conducted with patients scheduled for colonoscopies. Demographic data and responses to questions on the Pittsburg Sleep Quality Index were obtained. The Pittsburg Sleep Quality Index asks questions about trouble sleeping, hours of sleep a night and others to determine the overall quality of sleep.

Three hundred thirty eight of the 1,240 patients interviewed were diagnoses with colorectal adenomas during their colonscopies. This group reported sleeping less than six hours compared to those without adenomas and this association remained even after adjusting for family history, smoking, and obesity using a waist to hip ratio.
