Factors that have shown to increase slow-wave sleep in the sleep period that follows them include intense prolonged exercise and body heating, such as immersion in a sauna or hot tub. Studies have shown that slow-wave sleep is facilitated when brain temperature exceeds a certain threshold.

What affects sleeptime?

How long does Slowwave sleep last?

between 70 and 90 minutes
These two sleep stages both present high voltage slow waves in the EEG that belong to the delta band (less than 3 Hz). Slow wave sleep usually lasts between 70 and 90 minutes in normal individuals, and takes place during the first hours of the night, as though our organism was making sure we got this essential sleep.

What happens when you don’t get enough slow-wave sleep?
