Stanford Neuroscientist Advocates Morning Cortisol Spike
A scientist named Andrew Huberman says that having a big increase in cortisol, a stress hormone, in the morning is good for your health.
Cortisol helps you wake up, gives you energy, and makes you alert.
Huberman suggests getting bright light, like sunlight, in your eyes soon after waking up.
If you can't get sunlight, using bright artificial lights or doing some exercise or movement can also help.
He says it's important to have high cortisol in the morning and low levels at night.
Too much cortisol all the time can be bad for your body, causing inflammation and making your immune system weak.
Stanford neuroscientist Andrew Huberman advocates for a morning cortisol spike to boost health.
Cortisol is essential for alertness, energy, and cognitive readiness, acting as a natural alarm clock.
Huberman recommends getting bright light, ideally sunlight, in your eyes within the first hour of waking.
Exercise or bodily movement in the morning can also help spike cortisol levels.
Chronic high cortisol levels can lead to inflammation and a weakened immune system.
