Erik Scherder highlights sleep importance as breathing technique gains attention

Neuroscientist Erik Scherder explains that a solid night's sleep is vital for brain health, describing the four sleep stages and emphasizing the restorative roles of deep and REM sleep. He advises keeping a regular bedtime, avoiding intense exercise, screens, and alcohol before sleep, and ensuring a calm pre‑sleep routine.

The 4‑7‑8 breathing method, popularized by American physician Andrew Weil, is presented as a simple technique to calm the nervous system and aid insomnia. By inhaling for four seconds, holding for seven, and exhaling for eight, the exercise can lower heart rate and reduce anxiety, especially when combined with good sleep‑environment practices such as a dark, cool room and consistent sleep schedule.
