However, before this is calculated, first each person needs to know the optimum amount of sleep they need.
For example, teenagers (14-17) need at least eight to 10 hours per day while adults (aged 18-64) require seven to nine hours.
On sleep amounts Osmun says it “can vary depending on your age, and usually you will require fewer hours of sleep as you get older.

After the amount of sleep required has been calculated, Osmun said the next step is to “work your way backwards from the time you need to wake up in the morning”.
“So, say you need to be awake at six o’clock and you’re aiming for the recommended seven hours sleep, your bedtime should be eleven o’clock at the latest.”
Osmun continued: “So, say you need to be awake at six o’clock and you’re aiming for the recommended seven hours sleep, your bedtime should be eleven o’clock at the latest.”
“It takes around 90 minutes to complete the four stages and a typical night’s sleep of between seven and nine hours has approximately four or five sleep cycles.”
DON’T MISS
In some cases, if these methods fail, some may turn to sleep remedies.
However, the NHS cautions, warning “these are no substitute for addressing the problems that cause poor sleep”.
It is considered far healthier to attempt to improve sleep through non-medicinal remedies.
A lack of sleep can also be detrimental to overall health, increasing the risk of conditions such as heart disease, diabetes, and poor mental health.
