Melatonin is a natural hormone produced by the pineal gland in the brain. It is released exclusively at night and plays a crucial role in regulating our sleep-wake cycle. While melatonin itself is not a sleep hormone, it acts as a signal to the brain that it's time to sleep, particularly in day-active animals like humans.

Typically, melatonin is released about 2-3 hours before we go to sleep. However, it can also be obtained in pill form, which contains a synthetic version of the hormone in a higher dose than what our bodies naturally produce. This can be beneficial for individuals who struggle with managing their sleep patterns due to shift work.

Melatonin can help shift workers in two ways. Firstly, it can adjust the timing of the circadian clock, allowing for better adaptation to different work shifts. Secondly, it can aid in promoting sleep during the day when working night shifts. It's important to note that melatonin is not a sleeping pill and should not be relied upon once the body has adapted to a specific shift schedule.

In addition to its direct effects on sleep and the circadian clock, melatonin can indirectly influence the light-dark exposure we experience. By promoting sleep, melatonin reduces the amount of light reaching our retinas, which in turn affects our circadian clock. When used correctly and timed appropriately, melatonin can help reset the circadian clock and improve sleep and alertness management.

What dosage and type of melatonin should I take for shift work?
When considering melatonin for shift work, it's essential to choose the right type and dosage. Fast-release preparations are typically recommended, with doses ranging from 1-3mg. It's important to avoid slow-release formulations, as they may stay in the system for too long and disrupt the circadian clock. However, it's worth noting that the quality and dosage of melatonin products can vary, so it's advisable to purchase from reputable sources and opt for "melatonin-only" products.

When should I take melatonin?
The timing of melatonin administration depends on various factors, including the desired effects, work shifts, and individual preferences. It's crucial to follow personalized advice from reliable sources, such as the Timeshifter app for shift workers. This app provides tailored information on when to take melatonin, along with guidance on light exposure and other factors that can complement its effects.

Is it safe?
While melatonin is generally considered safe for short-term use, it's important to be aware of potential side effects and interactions with other medications. Headaches, sleepiness, vivid dreams, and nausea have been reported as possible side effects. Long-term safety and interactions with other drugs have not been extensively studied, so it's advisable to consult a healthcare professional before using melatonin, especially if you have any underlying medical conditions or are taking other medications.

In conclusion, melatonin can be a helpful tool for managing shift work, particularly when combined with proper light exposure. The Timeshifter app offers valuable guidance for shift workers, providing personalized advice on melatonin usage and optimizing sleep and alertness. It's always important to prioritize safety and consult a healthcare professional before starting any new supplement or medication.
