How does shift work affect sleep?

Shift work can significantly disrupt sleep and overall health. Andrew Huberman emphasizes the importance of maintaining a consistent schedule when doing shift work. Here are the key points covered by Dr. Huberman:

1. Consistency is Key: Staying on the same shift, ideally for at least two weeks, helps minimize the detrimental effects on the brain and body 1.

2. Avoiding Swing Shifts: Rotating between day and night shifts (swing shifts) can severely impact health, disrupting cortisol levels, learning capacity, and overall well-being 1.

3. Use of Red Light: For those needing to stay awake at unusual hours, using red light can help minimize disruption to the normal cortisol rhythm, thereby aiding in maintaining alertness without major disturbances to sleep-cycle hormones 2.

4. Impact of Light Exposure: Proper management of light exposure is crucial, especially for night shift workers. Viewing the sunset can help signal wakefulness at the start of a night shift, but it's advised to avoid bright light before sleeping to aid in transitioning back to daytime alertness 3.
