From the Guidelines
Working 22 hours straight with only 2 hours of sleep is extremely challenging and potentially dangerous, and I strongly advise against it due to the significant risks of impaired cognitive function, increased error rate, and negative impact on overall health and well-being, as highlighted in the guidelines on human factors in critical situations 2023 1. To minimize the risks associated with sleep deprivation, I recommend the following strategies to help maintain focus and sanity during the working hours:
- Strategic caffeine consumption: 100-200mg (one strong coffee or energy drink) at the beginning of your shift and another dose midway through, but stop 6 hours before your sleep period, as excessive caffeine consumption can exacerbate sleep deprivation effects.
- Stay hydrated with water throughout your shift and consume small, protein-rich meals every 3-4 hours to maintain stable blood sugar levels.
- Take brief 10-15 minute power naps if possible during breaks, as this can help improve cognitive function and reduce sleep debt, although it is essential to note that naps should not replace regular sleep.
- Use bright light exposure during work hours to help regulate your circadian rhythms and consider 200mg of L-theanine to reduce jitteriness from caffeine.
- For your 2-hour sleep window, make it as efficient as possible by sleeping in a dark, cool room without interruptions, and aim to get at least 10-13 hours of quality sleep, which may include a nap, with consistent sleep and wake-up times, as recommended for pediatric health behavior guidelines 1. However, it is crucial to emphasize that this approach is not sustainable or healthy long-term, as severe sleep deprivation impairs cognitive function similar to alcohol intoxication, weakens your immune system, and increases accident risk, as highlighted in the guidelines on human factors in critical situations 2023 1. Your body needs 7-9 hours of sleep for proper functioning, and this extreme schedule should only be used in rare emergency situations.

From the Research
Strategies for Maintaining Focus and Sanity During Prolonged Work Hours
To maintain focus and sanity during 22 hours of straight work with only 2 hours of sleep, consider the following strategies:
- Take breaks to refresh and recharge, as prolonged work hours can lead to decreased productivity and increased fatigue 2
- Use stimulants like caffeine or modafinil to help maintain alertness and performance, but be aware of potential side effects and use them in moderation 3, 4
- Prioritize tasks and focus on the most critical ones to help stay motivated and directed
- Stay hydrated and energized with nutritious food and drinks to support cognitive function
Managing Sleep Deprivation and Fatigue
Sleep deprivation can have significant effects on cognitive performance, mood, and overall well-being:
- Be aware that sleep deprivation can impair cognitive function, judgment, and decision-making abilities 3, 4
- Recognize the risks of fatigue-related errors, accidents, and decreased productivity 2, 5, 6
- Consider the long-term effects of prolonged work hours and sleep deprivation on mental health, including increased symptoms of anxiety and depression 5, 6
Mitigating the Effects of Prolonged Work Hours
To minimize the negative effects of prolonged work hours:
- Establish a consistent sleep schedule and prioritize sleep when possible 2
- Use evidence-based countermeasures to reduce fatigue and fatigue-related risks, such as taking regular breaks and staying hydrated 2
- Be mindful of individual limitations and take steps to manage stress and maintain a healthy work-life balance 5, 6
