People who restrict their sleep or are engaged in shift work where sleep becomes fragmented and disturbed are at risk for cardiovascular disease. This has been shown in nurses who have been engaged in shift work over a long period of time. They show an increased risk for heart attacks. Sleep debt can also contribute to depression, and lost sleep creates dangers at work and on the roads. Sleep deprivation results in impairment in people's capabilities to operate in their usual, expected way, and they would not necessarily know that they are impaired.
Most people require roughly seven to eight hours of sleep a night to stay alert through the day.
Even while getting 7 to 8 hours of sleep, starting with middle age, and worsening from there on, sleep tends to become less and less deep. Deep sleep, known as stage III and IV sleep, is where most of the healing, repair and regeneration takes place. It is also when the body secretes the most growth hormone. Therefore, promoting deep sleep is a key to feeling young in body, mind and spirit. And by using the right combination of lifestyle and products, you can come closer, at least.
