Sleep is key for both learning and memory, and people who lack sleep often experience impairments in these abilities. Sleep deprivation can cause problems with memory and learning, particularly in people who are trying to learn new information. Sleep is also important for health and well-being, and research shows that it helps to restore and enhance memory and learning ability.

• 00:05:00 Sleep is essential for both the brain and body. Sleep loss has negative consequences for health, including increased heart rates and car accidents. Sleep deprivation also affects the immune system, leading to increased rates of infection. Sleep is important for memory and learning, and recent research suggests that it may be one factor in the decline in cognitive function in aging and Alzheimer's disease. Direct current brain stimulation, which is minimally invasive and can improve memory function, is being developed as a method for restoring sleep in older adults and those with dementia.
• 00:10:00 Short sleep duration is associated with a number of health problems, including cancer. In this study, healthy adults were limited to four hours of sleep a night for one night and their gene activity was measured. There were two major findings: 1) a sizable and significant 711 genes were distorted in their activity, caused by a lack of sleep, and 2) about half of those genes were actually increased in their activity. Regularity and keeping it cool were also found to be helpful in improving sleep quality.
• 00:15:00 Matt Walker explains that, while we can't catch up on sleep, sleep is still a necessity, and that, to stay asleep, it's important to aim for a bedroom temperature of around 18 degrees Celsius (65 degrees Fahrenheit). He also advises avoiding sleep deprivation by prioritizing and breaking the association between bed and wakefulness.
