Reviews: The Importance Of Regular Exercise

Mayo Clinic (April 20, 2023) – Fitness training balances five elements of good health. Your overall exercise plan should include aerobic fitnessstrength trainingcore exercisesbalance training, and flexibility and stretching

  1. Exercise controls weight.
    Exercise can help control your weight, prevent excess weight gain or maintain weight loss. When you take part in physical activity, you burn calories. The more intense the activity, the more calories you burn.
  2. Exercise combats heart conditions and diseases.
    Being active boosts high-density lipoprotein, or HDL or “good,” cholesterol, and it decreases unhealthy triglycerides. This one-two punch keeps your blood flowing smoothly, which decreases your risk of cardiovascular diseases.
  3. Exercise improves mood.
    Physical activity stimulates various brain chemicals that may leave you feeling happier, more relaxed and less anxious. You also may feel better about your appearance when you exercise regularly, which can boost your confidence and improve your self-esteem.
  4. Exercise boosts energy.
    Regular physical activity can improve your muscle strength and boost your endurance. Exercise delivers oxygen and nutrients to your tissues and helps your cardiovascular system work more efficiently. And when your heart and lung health improve, you have more energy to tackle daily chores.
  5. Exercise promotes better sleep.
    Regular physical activity can help you fall asleep faster, get better sleep and deepen your sleep.
  6. Exercise puts the spark back into your sex life.
    Regular physical activity can improve energy levels and increase your confidence about your physical appearance, which may boost your sex life. Regular physical activity may enhance arousal for women, and men who exercise regularly are less likely to have problems with erectile dysfunction than men who don’t exercise.
  7. Exercise can be fun and social.
    Exercise and physical activity can be enjoyable. Exercise gives you a chance to unwind, enjoy the outdoors or simply take part in activities that make you happy. Physical activity also can help you connect with family or friends in a fun social setting.

Studies: 39% Of Americans Suffer Sleep Disorders

This Friday, March 17, is World Sleep Day, an annual event that aims to raise awareness of the importance of getting a good night’s sleep. This year’s campaign tagline is “Sleep is essential for health.” According to a study by the American College of Cardiology, up to 8 percent of deaths from any cause could be attributed to “poor sleep patterns”, while those with healthier sleep habits are less likely to die prematurely.

Data from Statista Consumer Insights shows that in the United States, 39 percent of respondents said they had suffered from a sleep disorder (problems falling asleep or staying asleep, insomnia, etc.) in the 12 months prior to the survey. Italians were among the worst sleepers in the survey at 48 percent reporting a sleep disorder, while India registered a higher share of good sleepers, with only 26 percent suffering from poor sleep.

Sleep & Aging : What Can Be Expected? (Yale Medicine)

Yale Medicine (March 12, 2023) – As we age, are melatonin starts rising at an earlier hour in the night, thus we may tend to go to sleep earlier than when we were younger. We still require the same number of hours of sleep (7-9 hours on average), so we may also rise earlier. Our sleep is more likely to be disturbed by medical conditions, medications, or substance use.

Research: Sleep Disorders Links To Brain Health

Research on sleep disorders and the importance of regular shut-eye has deepened our understanding of the link between sleep and brain health.

February 2023

Overall, there are more than 80 sleep disorders, ranging from the mildly annoying to the potentially deadly. The best known is probably insomnia; about 10 percent of the general population has chronic insomnia, an inability to fall asleep for multiple nights over a period of months.

Addressing sleep disorders “is paramount to not only protecting the brain down the road but also on a day-to-day basis,” says Daniel Barone, MD, associate medical director of the Weill Cornell Center for Sleep Medicine in New York City and co-author of The Story of Sleep: From A to Zzz (Rowman & Littlefied, 2023). “One of the best ways to take care of our brains is by getting quality sleep.”

Intriguing Clues

Research on sleep disorders has led to improvements in treatment for a variety of sleep and neurologic conditions. Case in point: Studies in the late 1990s on the causes of narcolepsy with cataplexy—the condition Connor was initially diagnosed with—led to the development of dual orexin receptor agonists, drugs now commonly prescribed to treat insomnia. The researchers discovered that people with narcolepsy with cataplexy often had low levels of hypocretins (orexins), brain chemicals that sustain alertness and prevent REM from happening at the wrong time.

“Once they found out, ‘If I take away your hypocretin, it makes you sleepy,’ there was a new idea of how to make a sleeping pill,” says Rafael Pelayo, MD, clinical professor of psychiatry and behavioral sciences at Stanford University School of Medicine in California and a sleep specialist at the university’s Sleep Medicine Center.

Supplements: Melatonin For Sleep Is Non-Addictive

Melatonin is a hormone that is naturally made by your brain in response to darkness,” says sleep specialist Marri Horvat, MD. “When someone takes melatonin, they are either trying to increase the amount of this hormone overall or increase the amount they have in their body at a certain time to help them fall asleep.”

While there are some possible setbacks to taking melatonin (depending on how your body reacts), it isn’t addictive. Turns out, even if you depend on melatonin to make you fall asleep, it won’t cause your body to become dependent on it.

“As we age, we have a natural decrease in the amount of melatonin we produce, so supplementation can often be helpful,” Dr. Horvat explains.

Old Age: ‘Hyperexcitable Neurons’ Interrupt Sleep

For many older adults, a good night’s rest is elusive. The implications of chronically poor sleep can be far-reaching and include a decline in cognitive functioning and detrimental effects on health and general well-being. Fortunately, relief may be in sight.

A new study led by investigators at the Stanford University School of Medicine shows that neurons in the lateral hypothalamus, a brain region, play a pivotal role in sleep loss in old mice. More specifically, the arousal-promoting hypocretin neurons become hyperexcitable, driving sleep interruptions.

Dr. C’s Journal: Recent Gains In Cancer Care

Recent medical advances in the treatment of cancer you have been amazing. Many of these advances have taken advantage of our own immune system‘s and fighting the cancer. If you or a loved one have had the recent diagnosis of cancer, there are several general things that you should know.

MVU MHA 2021 Q4 Infographic_ Advances, Breakthroughs, and Innovations in Cancer Treatment

The amazing technological advances in medicine have a come with a price tag, more than just the astronomical cost.

Preventative medicine it is given little attention in the medical profession these days, it wasn’t that great in the past either. The reason? Doctors don’t get paid to prevent disease; they get paid for treating it, and doctors are merely human beings like the rest of us and have a fondness for making money. Besides, the individual patient never knows whether he would’ve gotten the disease, had he not tried to prevent it. It takes a large number of people in a planned study to discern that.

Sleep, diet and exercise have all been casualties.

If you have established cancer, your tendency will be to give up on any exercise that you have been doing. This is an error. Depression is very common in patients with cancer, and inactivity makes it worse. Exercise is the one of the best things you can do for depression, and it may well  benefit cancer itself. To be sure to ask your doctor directly about this.

Diet is also extremely important. Many Cancers produce substances that kill the appetite. Weight loss in cancer is one of the hallmarks of the disease. It becomes very important to maintain a good diet.

Sleep is also very important. Just a day or two with poor sleep can harm the Immune cells, and with immune system damage, cancer can only worsen.

Drug studies improve medical care. They also deliver care free of charge, except for your time in taking part in the study. The usual Cancer study compares the new drug with established treatment. There is minimal worry that you are going to be getting a sham treatment.

Certain medical centers are known to specialize in certain areas of cancer treatment. For instance, in Southern California, the University of San Diego is known to be a Center that treats pancreatic cancer. The city of Hope in Los Angeles is known to be a center specializing in CAR-T cell treatment, A promising if expensive treatment for pancreatic cancer. 

It is very definitely worth your while to check into the availability of specialized care centers and drug studies in your area.

One of my friends developed melanoma and was told by his doctor to get his affairs in order. This absurd statement was made by a cancer doctor in one of the best hospitals in our area. In checking with an oncologist of my acquaintance, I found that a mere 30 miles away was a center specialized in the treatment of Malignant Melanoma. He went to the center for treatment, and was given a drug called a checkpoint inhibitor. He was virtually asymptomatic in a year. Unfortunately, patients can rarely expect such dramatic results.

In the history of the world, it has never been easier to learn about your disease, in this case cancer, and participate in its treatment. Especially in medicine, the best is none too good; it pays to do your homework, or at least find a medical advocate who will pursue your cause.

Mayo Clinic: What Are The Best Sleeping Positions?

Back-sleepers beware. “I know many people find it to be comfortable, because they’re not putting weight on their joints,” says Dr. Lois Krahn, a Mayo Clinic sleep specialist. But Mayo Clinic experts say sleeping on your back is actually the worst sleeping position, especially if you have sleep apnea. “Sleeping on the back means that your tongue and jaw can fall down and crowd your airway. And many people snore more on their back,” says Dr. Krahn. Sleeping on your stomach helps keep the airway open, but it can put a strain on your spine and neck. “There’s a host of evidence overall suggesting that probably sleeping on the side is better,” says Dr. Virend Somers, a cardiologist and director of the sleep facility within Mayo Clinic’s Center for Clinical and Translational Science.

Weight Gain: How Lack Of Sleep Makes You Hungrier
