Dementia has become a growing issue globally. Dr Dean Sherzai And Dr Ayesha Sherzai, authors of a new book The Alzheimer’s Solution, explain sleep can be your best defence against the disease and how not enough of rest could lead to it, in a report by the Daily Mail.

Seven to eight hours of sleep is a must to get rid of the toxins as well has unhealthy thoughts and memories. When you’re asleep, "the brain undergoes its routine repairs, and the regeneration of neurons and their supporting cells can occur". Chemicals released during this state also help boost one's immunity and calm inflammation. A well-rested person is also less prone to the flu and has lower risk of cancer.
Poor quality sleep
Less sleep leads to "brain atrophy and shrinkage" and destroys healthy neurons. Experts also warn the experience of "brain fog" after a bad night's sleep is the same in Alzheimer’s disease. Not enough sleep also affects your ability to function, focus and retain memory when you are awake. Sleep deprivation can also make it difficult to perform simple actions and cause you to make poor decisions. For older people, poor sleep quality can affect hand-eye co-ordination, increase the likelihood of falls and car accidents.
Sleep and food

Studies have also shown a link between poor sleep and the body's ability to process insulin. These factors can contribute to developing type 2 diabetes, which has been linked to dementia.
