Reset Your Body Clock

It's common to feel unusually tired the week after the clocks change.

That’s not just in your head.

The shift caused by Daylight Saving Time can temporarily disrupt your circadian rhythm - the internal clock that regulates sleep, metabolism, hormone production, and alertness.

One of the simplest ways to help reset that clock?

Step outside and get some morning light.

Even 5–20 minutes of morning sunlight soon after waking can help signal to your brain that it’s time to be alert and active.

Natural daylight is far more powerful than indoor lighting:

• Typical indoor light: 100–500 lux

• Outdoor daylight: often 10,000–100,000 lux

Your body evolved to run on sunlight.

Within the True Iron Will philosophy, many of the most powerful health practices are simple habits that align with human biology.

Morning light is one of them.
