Are your lights are putting you in a bad mood or making you sick?

That is what the data suggests to the authors of the article Timing of light exposure affects mood and brain circuits published in Translational Psychiatry.

Exposure to artificial light at night is linked to risk of breast cancer, metabolic disorders and psychiatric and behavioral disorders

Circadian disruption by nighttime light perturbs those processes and is associated with increasing incidence of certain cancers, metabolic dysfunction and mood disorders

Sleep disruption is a diagnostic criterion for major depression, bipolar disorder, post-traumatic stress disorder, generalized anxiety and other mood disorders

Artificial light is a relatively new thing in human history. We are still learning about the impacts of artifical light on human health.

Over the past century, the boundaries of day and night have been obscured by the widespread adoption of electric light at night . . . This amount of nighttime light exposure is unprecedented in human history

The main focus is the role of artificial light at night in mood regulation.

Light at night confuses your circadian rhythm because your system thinks it is daytime when really it is nighttime.

Exposure to light at night perturbs the circadian system because light is the major entraining cue used by the body to discriminate day and night

Disrupting your sleep schedule can put you in a bad mood, give you negative emotions, or worse.

circadian disruption alters the function of brain regions involved in emotion and mood regulation

Here are things they say that disrupt your circadian cycle.

• Nighttime indoor light exposure to the eyes
• Nighttime exposure to city lights at night
• Using electronics at nighttime
• Irregular daily light cycle
• Constant light intensity

Easily avoid disrupting your circadian cycle by incorporating daily habits that are predictable and consistent with the daily light cycles of the sunshine.

• Avoid electronics with screens during the 4 h before bedtime
• Get exposure to bright light during the day
• Switch to incandescent bulbs
• Avoid compact fluorescent bulbs
• Avoid light-emitting diodes (LEDs)
• Keep consistent eating schedule
• Keep consistent daily body temperature schedule

Simple daily habits can reinforce the biochemical environment you need to thrive.

temporal organization of physiology is . . . important for health and wellness

Predictable daily cycles of light and dark allow for the synchronization of behavioral and biological processes to the external environment.

It is not just about the direct effect of the light rays hitting your eyes. More is at stake.

Many systems are under circadian control, including sleep–wake behavior, hormone secretion, cellular function and gene expression.
