Brains are very susceptible. Steer yours properly. View the sunrise, thank God for another day living and then go get meaningful things …

what it claims

Exposing yourself to sunlight first thing in the morning is essential for orienting your mental state and optimizing your daily productivity.

This advice is based on the principles of chronobiology, specifically the effect of morning light on the circadian rhythm. Research shows that exposure to natural light (ideally 10 to 30 minutes shortly after waking) triggers a release of cortisol and promotes the production of melatonin approximately 14 to 16 hours later, which helps regulate the sleep-wake cycle (meta-analysis, chronobiological studies). The link between this exposure and improvements in mood or cognitive alertness is also supported by observational studies and randomized controlled trials (RCTs). However, asserting that this allows one to 'direct' their brain to accomplish significant things is a motivational interpretation rather than a direct biological mechanism. The 'focus test' aspect when faced with distractions is a behavioral tip related to attention management, which, while consistent with cognitive load theories, does not constitute a strict biological law. There is no evidence that morning light alone negates the impact of social distractions, but it undeniably establishes the physiological foundations for an optimal state of wakefulness.

What the graded evidence says

Evidence: A-

Effect: circadian phase / melatonin timing — morning light advances; evening light delays
Measured on: reviews + expert consensus

Core circadian physiology is very well established; specific lux targets less so.

Intermittent fasting is only effective for weight loss if it results in a reduction of total caloric intake. However, meal timing matters: eating earlier in the day optimizes fat utilization, while avoiding food intake immediately before sleep stimulates growth hormone production and improves sleep efficiency, thereby allowing one to get by on less sleep.

Slight sleep deprivation distinctly disrupts hunger and satiety signals in men and women, promoting weight gain that is explained by both increased hunger and a decrease in daily energy expenditure.

To optimize learning and stimulate brain plasticity, it is appropriate to follow an active process: maintain a state of wakefulness and alertness, focus your attention intensely, and accept the mental agitation caused by your own errors, because these are what signal to the brain that it needs to adapt.

Other advice in the Register that leans on the same research.

To dispel the feeling of being exhausted but overstimulated at bedtime, adopt a regular and relaxing sleep routine (low light, calm sounds, no screens) coupled with a progressive light alarm.

Fix light, timing, temperature, and routine (sleep hygiene) before adding supplements or medication; he also recommends wearing blue-light-blocking glasses in the evening.

The quality of your sleep, the time you fall asleep, and your state upon waking are primarily determined by exposure to sunlight before 10 a.m. over the preceding 2 to 3 days.
