There are plenty of reasons why it might be hard to get those recommended hours.
It could be an early morning work shift or a stressful event that keeps you tossing and turning. Whatever the case, those precious eight hours often feel out of reach.
“If you think that you can survive on only four to five hours of sleep every night, you’re going to have an early death,” he warned.

“Increased mortality all across the board, cardiovascular disease, all types of diseases are associated with sleeping that little.”
Over the years, many studies have found a strong link between sleep deprivation and higher chances of developing neurological disorders, including Alzheimer’s.
People who regularly sleep fewer than six hours a night also face an increased risk of strokes, heart disease, kidney problems, and diabetes.
In a 2022 study, a team of researchers from the US found that those who sleep for less than 4.5 hours or more than 6.5 hours each night are more likely to experience a decline in cognitive abilities over time.
Writing for The Conversation, senior psychology lecturer Greg Elder noted: “The study showed that sleeping longer than 6.5 hours was associated with cognitive decline over time – this is low when we consider that older adults are recommended to get between seven and eight hours of sleep every night.”
Healthline advises that adults between the ages of 18 and 64 should aim for between seven and nine hours of sleep each night, while those who are 65 and older should try to get between seven and eight hours of rest.
