You’ve probably heard it said that exercise is medicine. Well, it’s not just a saying; it’s the truth. There’s a raft of scientific evidence that proves that regular exercise (150 minutes per week, which is about 30 minutes five times per week)-and running in particular-has health benefits that extend well beyond any pill a doctor could prescribe. Studies have shown that running can help prevent obesity, type 2 diabetes, heart disease, high blood pressure, stroke, some cancers, and a host of other unpleasant conditions. What’s more, scientists have shown that running also vastly improves the quality of your emotional and mental life, and even helps you live longer. Here’s how:
1. Running makes you happier.
If you’ve been working out regularly, you’ve already discovered it: No matter how good or bad you feel at any given moment, exercise will make you feel better. And it goes beyond just the “runner’s high”-that rush of feel-good hormones known as endocannabinoids.
In a 2006 study published in Medicine & Science in Sports & Exercise, researchers found that even a single bout of exercise-30 minutes of walking on a treadmill-could instantly lift the mood of someone suffering from a major depressive order. In a May 2013 study in Medicine & Science in Sports & Exercise in which rats and mice got antidepressant-like effects from running on a wheel, researchers concluded that physical activity was an effective alternative to treating depression.
And even on those days when you have to force yourself out the door, exercise still protects you against anxiety and depression, studies have shown.
Moderate exercise may help people cope with anxiety and stress even after they’re done working out, according to a 2012 study published in Medicine and Science in Sports & Exercise. A 2012 study in the Journal of Adolescent Health proved that just 30 minutes of running during the week for three weeks boosted sleep quality, mood, and concentration during the day.
Ever heard someone call running their “drug”? Well, apparently, it actually is pretty similar. A 2007 study in Physiological Behavior showed that running causes the same kind of neurochemical adaptations in brain reward pathways that also are shared by addictive drugs.
Obesity and leptinThe hormone leptin is produced by fat cells and is secreted into our bloodstream. Leptin reduces a person’s appetite by acting on specific centres of their brain to reduce their urge to eat. It also seems to control how the body manages its store of body fat.Because leptin is produced by fat, leptin levels tend to be higher in people who are obese than in people of normal weight. However, despite having higher levels of this appetite-reducing hormone, people who are obese aren’t as sensitive to the effects of leptin and, as a result, tend not to feel full during and after a meal. Ongoing research is looking at why leptin messages aren’t getting through to the brain in people who are obese.
Obesity and insulinInsulin, a hormone produced by the pancreas, is important for the regulation of carbohydrates and the metabolism of fat. Insulin stimulates glucose (sugar) uptake from the blood in tissues such as muscles, the liver and fat. This is an important process to make sure that energy is available for everyday functioning and to maintain normal levels of circulating glucose.In a person who is obese, insulin signals are sometimes lost and tissues are no longer able to control glucose levels. This can lead to the development of type II diabetes and metabolic syndrome.Read more at:
As the medical field is becoming more concerned with illness that plagues females, more and more information is coming to light about the complex organism that is the female body. Only a little over a hundred years ago, women were accused of having “hysteria” instead of being treated for what was wrong with them. The word “hysteria” comes from the latin word for uterus. It is now much less taboo to talk about female sexuality and we have found that a problem that plagues nearly half of women is called Female Sexual Arousal Disorder.
Once seen as mostly a psychological issue, in recent years female sexual dysfunction (FSD) has been recognized as a wide spread problem with physiological aspects that are treatable. According to reported data, up to 43 percent of women in the United States experience some form of FSD. One of the most commonly reported types of FSD is female sexual arousal disorder (FSAD).Female Sexual Arousal Disorder (FSAD)
- FSAD is the persistent or recurrent inability to attain or maintain the lubrication-swelling response of sexual excitement until completion of sexual activity
- Arousal disorder is characterized by a lack of vaginal lubrication; decreased clitoral and labial sensation; decreased clitoral and labial engorgement; or decreased sexual arousal and excitement
- When these symptoms cause significant personal distress to the women affected, a diagnosis of FSAD is made
- FSAD occurs despite adequate focus, intensity and duration of sexual stimulation
Causes of FSAD
- Surgical procedures such as a hysterectomy may affect changes in blood flow, which can cause a lack of sensitivity and sexual arousal
- A hysterectomy, with or without oophorectomy (removal of ovaries), may also affect how a woman feels about herself sexually
- The decrease in estrogen levels associated with menopause may make the vagina dry and thin, even causing it to shrink
- Certain medications such as oral contraceptives, antihypertensives and antidepressants, may impact sexual function and libido; Women taking these drugs may report a decrease in arousal, increase in vaginal dryness and increase in difficulty reaching orgasm
- Psychological factors such as depression, stress and relationship issues may cause or contribute to FSAD
- Other causes include certain chronic diseases like diabetes, lifestyle choices such as cigarette smoking, and surgical trauma or nerve damage to the pubic area
