Given the high prevalence of infertility as well as vitamin D insufficiency in otherwise healthy young women and men and the possible link between vitamin D and human reproduction, is being researched by scientists. Vitamin D has been well-known for its function in maintaining calcium and phosphorus homeostasis and promoting strong bones and teeth. There is some evidence that in addition to sex steroid hormones, the classic regulators of human reproduction, vitamin D also modulates reproductive processes in women and men.  It is well known that Vitamin D peaks in the summer months and drops in the winter months in the Uk and other northern countries that have fewer hours of day light during the winter months.  In these northern countries the conception rate is decreased during the dark winter months; it peaks during the summer leading to a maximum birth rate in the spring. In women with polycystic ovary syndrome (PCOS), low 25-hydroxyvitamin D (25(OH)D) levels are associated with obesity, metabolic, and endocrine disturbances.   Polycystic ovary syndrome is a common cause of infertility.  Researchers concluded that vitamin D supplementation might improve menstrual frequency and metabolic disturbances in those women. The same researchers suggested vitamin D might influence steroidogenesis of sex hormones (estradiol and progesterone) in healthy women and high 25(OH)D levels might be associated with endometriosis. In men, vitamin D is positively associated with semen quality and androgen status. Moreover, vitamin D supplementation might increase testosterone levels. It should be noted that Vitamin D supplementation can't treat infertility alone, but is a safe and cheap treatment, which has been shown to boost fertility in men and women. In addition there is limited evidence that vitamin D exerts some effects on the outcome of IVF treatment. Finally vitamin D deficiency among pregnant women has been associated with elevated risk for other pregnancy complications such as preeclampsia and bacterial vaginosis.

In my previous post I said that the activity you do to chill out doesn't matter it you just need to enjoy it and it absorbs you. So why not consider paying video games, yes video games.  If you ask any gamer, who enjoys playing them and they will tell you it help them relax or de-stress.  I know this may sound unlikey.  However that is scientific research to support the idea that regularly playing video games can help people unwind an dimprove their ability to handle everyday stress. In 2010 Associate Professor Dr. Christopher J. Ferguson of the Texas A&M Public Research Facility demonstrated that both men and women who play violent video games long-term seem to be able to adopt mental skills to handle stress, become less depressed and get less hostile during stressful tasks.  In 2014 reserarchers from University College London  found that people who played video games after work experienced faster recovery from work related stress. While there are a number of video games on the market which are specifically aimed at helping people unwind and manage stress, it seems that almost any form of game playing will do the trick.  Spending half an hour each day on a video console could be be as effective as going to the gym for helping you “chill out” at the end of a busy day.

Like a trusty guard dog, your smart phone probably rests right next to you (or even under your pillow) every night when you go to sleep. You’re able to answer calls, texts and emails at a moment’s notice – even during the wee hours of the night.  And isn’t that the best part about technology? Always being connected and never truly shutting down or logging off?  Not so fast. You probably don’t even realize how your smart phone habits are affecting your sleep. 1. It keeps your mind psychologically engaged Smart phones were designed to make us more productive and our lives easier. They’re designed to entertain us and provide information. But when it’s time to turn off the lights and go to sleep, the last thing our brain needs is more information and more entertainment. (And that seems fair enough – we give our brains enough to think about during the day!) The smart phone era has forced us to feel like we can never really log off, even when we’re sleeping.   Your mind can stay active and engaged long after you’ve scrolled through Instagram or responded to a few work emails. Going to bed and falling asleep should be a peaceful, happy and relaxing experience. Engaging with your phone too close to bedtime can negatively impact those feelings. 2. The blue light from the screen suppresses melatonin Blue light from screens of laptops, tablets and smartphones supresses melatonin.  Melatonin is a hormone responsible for controlling your sleep-wake cycle. So when your body runs low on it, you can experience insomnia, tiredness during the day and irritability. 3. Alerts delay REM sleep Knowing your smartphone is at hand can mean you are aware of new email alerts or social media alerts.  These alerts or simply waiting for these alerts can delay REM sleep. So if you want to improve the quality of your sleep simply have 1 hour technology free before bed. Reference https://www.physiology.org/doi/full/10.1152/japplphysiol.01413.2009
