Is 8-hour straight sleep better than divided sleep?

Experts say that sleeping for 7–8 hours straight is the most natural and restorative.

This helps with memory, immunity, mood, and overall energy.

However, some people naturally follow a biphasic pattern, like 6–7 hours at night and a short nap during the day.

Historically, some cultures followed a pattern of 'first sleep' and 'second sleep,' but today, one consolidated block of sleep fits better with modern routines.

Divided sleep can work for certain groups like shift workers or new parents, but it's usually a temporary solution.

Fragmented sleep can decrease slow-wave sleep, which is important for memory and emotional balance.

It can also make you feel more tired during the day.

If you naturally wake up at night, it's not necessarily unhealthy unless the awakenings last too long or occur too often.

The best sleep routine is the one that makes you feel comfortable and clear.

Quality of sleep matters more than the clock.
