Shoulder flexibility exercises

These stretches can either be done as a complete series or individually and most of them can be done at your desk.  Some will ease tension in specific parts of the body whilst others are generally relaxing.  Please remember stretching should always be relaxing and never painful! To get maximum benefit from these stretches you should do them daily and hold each stretch for 15 seconds and repeat twice. Head And Neck

• Head rotation - keeping your head level, slowly turn from side to side.
• Slowly drop your head sideways moving your right ear towards your right shoulder and push down with your left shoulder - repeat on other side.
• Stand with your feet shoulder distance apart; look down towards your right foot (hold for 15 seconds),  dropping left shoulder - repeat the exercise looking towards your left foot.
• Drop the lower jaw and open the mouth wide.

• Shrugging shoulders in a circular movement - forwards and then backwards.
• Raise your shoulders high and let them drap heavily; whilst letting breathing out.
• Clasp hands behind your head, with elbows back - push your chin back.  Hold for 15 seconds.  From this position look down and push your elbows together at the front and hold for a further 15 seconds.
• Clasp you hands and push up towards the ceiling, palms up now look down.
• Sit upright in a chair with a firm seat.  Raise your arms as high as possible and remaining seated drop forward letting your head and arms hang heavily towards the floor.

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.
