Sleep experts continue to advocate for structured routines and environmental adjustments to regulate circadian rhythms. Central to these recommendations is the 10-3-2-1-0 rule and the importance of morning habits, such as seeking natural light and eating breakfast within an hour of waking. Neurobiologist Andrew Huberman identifies morning light exposure as a key pillar for health, and a 2023 study by Chinese scientists suggests even brief exposure can help calibrate the brain and improve sleep quality. Conversely, experts warn against scrolling through social media immediately upon waking, as it can lead to a state of ‘functional freeze’ and cause cortisol to spike beyond safe norms, increasing anxiety. ~~To optimize the sleep environment, specialists suggest using natural fibers and positioning beds away from windows, doors,~~ Recent guidance expands on these routines, with cardiologist Sanjay Bhojraj advising against consuming sugary pastries or ~~noisy appliances~~ processed meats like bacon and sausages before 9:00 AM. This precaution aims to ~~minimize temperature~~ prevent rapid blood sugar fluctuations during a period when cortisol levels rise and ~~drafts.

An ideal bedroom temperature is approximately 18 degrees Celsius. Light management~~ utilizing natural daylight to synchronize the internal biological clock. Spatial planning is also critical. While blackout curtains can block sunlight and regulate temperature, users should note that total darkness may disrupt natural waking signals. Regarding hygiene, research indicates that used bedding can host fungi and dust mites; becoming a factor in sleep hygiene. For those integrating home offices into small bedrooms, experts ~~advise leaving bedding unfolded for at least an hour to allow for ventilation~~ suggest creating visual separation between work and ~~washing linens weekly at temperatures~~ rest zones. Recommended workspace dimensions include a desk depth of at least ~~60°C.
