Circadian Rhythm Disruption Can Undermine Focus, Mood And Brain Health

Why Your Brain Needs A Healthy Body Clock: Understanding The Impact Of Circadian Rhythm Disruption · NDTV

Your body has an internal clock that helps control when you feel awake or tired.

It uses clues such as daylight, activity and daily routines.

Waking in the afternoon every day can make your body treat that time as morning.

Exercising late at night can keep your body warm and your brain alert.

This may make it harder to fall asleep at a regular time.

Poorly timed sleep can make it harder to focus and may affect mood.

Getting daylight soon after waking can help move the body clock earlier.

Exercising earlier and relaxing before bed may also help.

Key facts

Main issue: Repeatedly mistimed sleep and activity can push the body clock later.
Body-clock cues: The brain uses light, activity and routine to set its internal clock.
Late exercise effect: Exercise can raise core body temperature and adrenaline, increasing alertness.
Suggested daylight exposure: Getting outside within the first hour or two after waking may help reset the clock.
Suggested workout timing: The article recommends finishing exercise at least three hours before bed where possible.
Evening habits: Dimming lights, reducing scrolling and limiting high-intensity stimulation may support winding down.
When to seek help: Persistent concentration problems, low mood or exhaustion should be discussed with a doctor.
