Research has proven that sleep is connected with subclinical atherosclerosis, the early stages of hardening and narrowing of the arteries. Those who slept for less than six hours a night were 27 percent more likely to have subclinical atherosclerosis than those who slept for seven or eight hours a night. People who sleep less than seven hours a night also have an increased risk of heart disease, and this is true regardless of other factors that influence heart health like age, weight, smoking and exercise habits. I encourage all my clients to aim for 7-8 hours each night. Sleep is essential for our bodies to heal and recover. Sleep routines, allowing melatonin release and improving circadian rhythms are all part of my 28 day programme to optimum health
