Sleep hygiene: fixing one evening habit helped me wake up full of energy

A doctor identified a 'higher-stimulus' evening environment—bright lights, screens and scrolling—as suppressing melatonin and keeping sleep light, and the article reports that shifting to lower-stimulus evening cues improved the author's sleep and morning energy.

The author reports waking up full of energy after a doctor identified a 'higher-stimulus' evening environment as the likely cause of lower-quality sleep. The piece explains that stimulation in the hours before bed—bright lights, multiple screens and social media scrolling—can keep the body in an alert, daytime state. Experts quoted in the article link this environment to hormonal effects, noting that bright light can suppress melatonin while mental stimulation can raise cortisol. The article describes a set of lower-stimulus evening cues that the author used and found helpful. What is known: - Higher-stimulus environments are described as those with bright lights, frequent screen use, and mentally engaging activities in the hours before bedtime. - Bright evening light and evening screen exposure are reported to suppress melatonin and can be associated with higher cortisol and lighter, more fragmented sleep. - The article cites research reporting a 59% increase in insomnia risk for each hour spent on screens in bed. - Experts quoted in the article describe lower-intensity evening cues—dimmer warm lighting, reduced screen use, wind-down routines, tidier bedrooms, and warm showers—as linked with improved ability to fall and stay asleep. Summary: The article reports that reducing evening stimulation helped the author fall asleep more easily, remain asleep, and wake earlier with more energy. Experts connect these changes to circadian cues and hormonal responses related to light and routine. Undetermined at this time is how consistently these results apply across different individuals and circumstances.
