Sleep is very important for your Brain Health. Adequate and quality sleep is needed for body repair and consolidation of learning and memory, as well as psychological functioning such as reduced feelings of stress and increase of positive moods.1 Getting the right amount of sleep also boosts your immune system, lowers your blood pressure and helps you stay at a healthy weight.
It is recommended that healthy adults need between 7 to 9 hours of sleep per night to function at their best. A chronic lack of sleep would not only negatively impact on cognitive and memory functioning but would also have many implications on health and wellbeing later in life. As you sleep your brain is hard at work processing all the memories of the day, while you sleep you blood pressure reduces, giving your heart and blood vessels a bit of rest. During deep sleep, the amount of glucose in your blood drops, reducing the likelihood of getting type 2 diabetes. Being sleep-deprived messes with the hormones in your brain -- leptin and ghrelin -- that control appetite.
The lack of sleep is big risk factor for many diseases such as cardiovascular diseases and dementia.2 Cognitively healthy adults whose sleep quality declined in middle age are more likely in late life to accumulate Alzheimer’s disease-related proteins in the brain than those whose sleep quality improved or did not change.
Sleep apnea is harmful to your brain’s health and may be the reason for interrupted sleep.3 Talk with your Doctor if you or a family member suspects you have sleep apnea.
