Viewing bright light early in the day helps synchronize the cortisol pulse, providing energy and focus for the day.

A natural increase in cortisol occurs early in the day, promoting wakefulness and a healthy immune system, and can be timed by exposure to bright sunlight.

Every person should ideally view bright light, preferably sunlight, within 30 minutes to an hour of waking up to optimize health.

If you don't view light early in the day, the cortisol pulse can shift later, leading to mood issues and sleep problems.

The rise in body temperature after your temperature minimum triggers cortisol release, which helps wake you up and enhances focus.

Getting sunlight in my eyes first thing in the morning is vital for mental and physical health, even on cloudy days, as it stimulates alertness.

Using red light in the hours before needing to be awake can help maintain your normal cortisol rhythm without disrupting sleep.

Engaging in activities like sunlight exposure, physical exercise, and cold exposure in the first phase of the day can enhance your alertness and focus, making it easier to adopt new habits.

Cortisol spikes in the morning are beneficial as they help wake us up and have important health-promoting functions, while a 9 PM cortisol spike is a signature of depression and anxiety, which is problematic and associated with many mental health issues.
