Sleep is an important part of a healthy lifestyle. Some studies show that people who get less than 7 hours of sleep are at an increased risk of poor health and functioning. Sleep timing and duration have an effect on the body’s metabolic, neurological and endocrine functions. Lack of sleep can increase the risk of heart disease, high blood pressure, obesity, diabetes and death. During menopause, many women find that their sleep cycles are disrupted. In fact, 61 percent of postmenopausal women experience symptoms of insomnia. Changing estrogen levels during this time frame may result in night sweats and hot flashes that interrupt sleep. So how can you get a better night’s sleep?
