“Sleep is that golden chain that ties health and our bodies together” – Thomas Decker
• One study found that people who routinely got less than seven hours sleep a night were three times more likely to catch the common cold. Those least likely to catch a cold were people who reported good quality sleep most nights.
• Getting enough sleep may help prevent cancer, because the sleep hormone melatonin appears to have cancer fighting and anti-tumour properties.
• A study of 24,000 Greek adults found that those who napped regularly had a lower risk of dying from heart disease.
• The glymphatic system in the brain clears it of a substance called beta amyloid — which is a precursor to Alzheimer’s. This system is 10 times more active when you’re sleeping than when you are awake. If you consistently get 7 – 8 hours’ sleep a night, your chances of contracting Alzheimer’s are reduced.
• Getting a good night’s sleep can reduce premenstrual symptoms, particularly those relating to mood.
• Insulin is the hormone that regulates your blood sugar level. Adequate sleep supports this function, while lack of sleep can lead to high blood sugar creating symptoms of diabetes in otherwise healthy people.
