On the night before a big test, make sure your high school student gets at least seven hours worth of sleep.  While that is less than what is currently recommended as adequate rest, a new study finds that 16 to 18 year olds perform better academically just under that amount

It has been estimated that up to 10% of school children suffer from sleep disturbances.  An insufficient amount of sleep leads to poor school performance and lower grades.  There also tends to be behavioral problems in children who don’t get enough sleep.  And teens who drive to school are at greater risk for accidents when they are drowsy.

Eric Eide and Mark Showalter with Brigham Young University analyzed data collected from a sample of just over 1,700 students.  They compared the amount of sleep they got and how they scored on standardized tests.  The optimal amount of sleep for a 10-year-old is 9 to 9.5 hours.  For a 16-year-old in high school, the magic number is 7 hours of sleep.

7 Strong Reasons to Take a Power Nap Today

Winston Churchill in Downing Street giving his...

"A nap in the afternoon gives you two days in one."

While talking to Dan Rather of CBS News in 1993, Bill Clinton said, “If I can take a nap—even fifteen or twenty minutes—in the middle of the day, it is really invigorating to me. On the days when I’m a little short of sleep, I try to work it out so that I can sneak off and just lie down for fifteen minutes, a half hour, and it really makes all the difference in the world.”

Because of our internal circadian rhythm, our alertness and, hence, our performance dips in the afternoon. This nadir is deeper when we are sleep deprived and when we are traveling across multiple time zones. If we can fight this drowsiness with a strategically placed power nap, then we can maximize our  efficiency and avoid fatal mistakes. (Most fatal vehicular accidents occur in the midafternoon and after midnight.)

Studies prove that a fifteen-minute power nap provides benefits lasting up to 150 minutes, including:

  1. Improved alertness, both subjectively and objectively
  2. Reduced fatigue and improved vigor
  3. Enhanced creativity and problem solving
  4. Improved perception
  5. Facilitated learning
  6. Improved declarative and procedural memory
  7. Positive mood and emotions, clearer communication, humor and optimism, and situational awareness

If a fifteen-minute nap gives you 150 minutes of improved executive function, how can you resist such an investment? Click here to learn the technique of PREM power nap.

9 Excuses People Make for Insufficient Sleep

English: A woman working on a call centre

Lack of work-life balance leads to insufficient sleep.

According to National Sleep Foundation, we need 7-8 hours of sleep to function at peak and enjoy our life to the fullest. But, my overworked colleagues, unaware of the above recommendation and the research behind it, continue to argue against sufficient sleep. Here, is a list of arguments made by skeptics of sufficient sleep and my responses:

  1. I don’t need eight hours of sleep. Studies have shown that restricting sleep to four or six hours (compared to eight hours) for fourteen days causes a dose-dependent decline in neurocognitive performance.
  2. I only need five hours of sleep. The short-sleeper gene, a rare mutation, is present in only 3 percent of the population (Ying-Hui Fu, University of California, San Francisco). The majority of working people get less than six hours of sleep, certainly during a major opportunity or catastrophe. Remember, there is a 97% chance that you are not a short-sleeper.
  3. I can fight sleep deprivation with strong motivation. Motivation improves attention but not creativity, flexibility, mood, perception, and information management.
  4. I have achieved a lot by sleeping less. You could achieve even more by sleeping more and working smarter.
  5. I don’t perceive the deficit in my performance. Sleep deprivation adversely affects prefrontal cortex (the executive center), which is essential for successful self-evaluation. This adverse effect makes us unaware of our deficit.
  6. I am highly productive. You have increased your output as a worker/manager, at the expense of your executive output.
  7. The stakes are so high that sleep has to be on the back burner. This is exactly the reason you should be giving sleep a top priority.
  8. I don’t want to sleep away a third of my life. Investment in sleep will enrich your life qualitatively, both at home and at work.
  9. I will sleep when I am dead. Unfortunately, studies have shown increased mortality associated with insufficient sleep. You must sleep eight hours every night if you want a successful career that can span five to six decades.

Sleep is a process of the brain, for the brain, and by the brain.


Sleep Doc’s 6 Tips for Sound Sleep during Menopause

It is possible to sleep well even with hot flashes!

The following tips will help you sleep better even during menopause.

  1. Avoid foods that are spicy or acidic because these may trigger hot flashes. Try foods rich in soy because they might minimize hot flashes.
  2. Avoid nicotine, caffeine, and alcohol, especially before bedtime. These will make your hot flashes worse.
  3. Dress in lightweight clothes to improve sleep efficiency. Avoid heavy, insulating blankets, and consider using a fan or air-conditioner to cool the air and increase circulation. If your spouse is shivering, have a small, portable heater next to his side of the bed.
  4. Reduce stress and worry as much as possible. Try relaxation techniques, massage, and exercise. Talk to a behavioral health professional if you are depressed, anxious, or having problems.
  5. It is vital that you follow sleep hygiene and insomnia instructions discussed in an earlier blog.
  6. Try consolidating your sleep by going to bed thirty minutes later than your usual bedtime. As we age, we spend more time in bed, but we sleep less.

During the transition phase leading to menopause, over several years, a woman’s ovaries gradually decrease production of estrogen and progesterone. One year after menstrual periods have stopped, a woman reaches menopause, usually around the age of fifty. Menopause is a time of major hormonal, physical, and psychological change. Natural changes in sleep also occur, characterized by longer time to sleep onset, frequent awakenings, decreased amount of deep sleep, and poor sleep architecture. From perimenopause to post menopause, women report hot flashes, mood disorders, insomnia, and sleep-disordered breathing. Sleep problems are often accompanied by depression and anxiety, which make insomnia worse. This is the reason post-menopausal women are not satisfied with their sleep. As many as 61 percent report insomnia symptoms. Snoring and sleep apnea have also been found to be more common and more severe in post-menopausal women as their upper airway dilator muscles become flabby with aging.

Changing and decreasing levels of estrogen cause many menopausal symptoms, including hot flashes, which are unexpected feelings of heat all over the body accompanied by sweating. They usually begin around the face and spread to the chest, affecting 75 to 85 percent of women around menopause. On average, hot flashes last three minutes and lead to reduced sleep efficiency. Most women experience these for one year, but about 25 percent have hot flashes for five years. Hot flashes interrupt sleep and reduce the amount of deep sleep, leading to suboptimal alertness and suboptimal leadership the following day.

Talk to your doctor about estrogen (estrogen replacement therapy or ERT) or estrogen and progesterone (hormone replacement therapy or HRT), nutritional products, and medications such as calcium supplements, vitamin D, and bisphosphonates for the prevention or treatment of osteoporosis (thinning and weakening of the bones). Also, talk about estrogen creams and rings for vaginal dryness. Also, discuss alternative treatment for menopausal symptoms such as soy products (tofu, soybeans, and soy milk). They contain phytoestrogen, a plant hormone similar to estrogen. Soy products may lessen hot flashes. Phytoestrogens is also available in over-the-counter nutritional supplements (ginseng, extract of red clover, or black cohosh). The FDA does not regulate these supplements. Their proper doses, safety, and long-term effects and risks are not yet known.

Typically, a leader’s career spans five to six decades. And toward the later part of your career, because of your vast experience, lifelong network of experts, and wisdom that comes only with age, you are worth more than you ever were. This makes it imperative that you take good care of your sleep so that you can continue to contribute to the welfare of the human race.

8 Reasons Why We are Grumpy When Sleepy

English: Managing emotions - Identifying feelings

Image via Wikipedia

The following list summarizes the deleterious effects of poor sleep on emotional intelligence:

  1. When sleep deprived, we are unable to accurately recognize emotions. To make matter worse, negative emotions are more readily recognized than positive ones.
  2. Studies have shown decreased subjective rating of happiness by sleep-deprived people.
  3. Our overactive fear center (Amygdala) exaggerates our fear and anger when sleep deprived.
  4. Sleep deprivation impairs our social interaction and learning because of perception fatigue.
  5. A study from the Neuroscience Lab in Singapore showed that when sleep deprived, we are reactive and not proactive.
  6. Nervousness, irritability, and grumpiness hurt our teamwork.
  7. Impaired self-evaluation resulting from sleep deprivation makes us unaware of our deficits.
  8. Studies have also shown reduced motivation, increased risk taking, and indecisiveness when faced with an ethical dilemma.

Hence, make sure you get 7-8 hours of sound sleep every night. And when you cannot get sound sleep because of unavoidable factors, please beware of these deleterious effects. Smile often, pause before responding, listen more than you talk, and you will be fine.

Sleep Well, Lead Well. God bless you.
