Shift workers frequently report sleep disruptions and increased levels of sleepiness, which may contribute to impaired performance and work-related accidents. This 23-day residential study examined the effects of the alerting agent modafinil on cognitive, psychomotor, and mood measures during simulated shift work.
The drug stimulates the brain and helps you stay awake and focus. It also relieves symptoms of narcolepsy and obstructive sleep apnea by altering neurotransmitters in the brain.
1. Increased energy
Shift workers typically work at times that conflict with their internal circadian rhythm and must perform at a time when they are at their circadian nadir of alertness. These conditions make them susceptible to performance decrements and may contribute to work-related accidents. Stimulants, such as Modalert 200 Price, have been shown to improve cognitive and psychomotor performance and mood in individuals working shifts. The present double-blind, within-participant study was designed to evaluate the effects of modafinil on behavioural changes associated with shift work in an experimental paradigm.
2. Boosted memory
Modalert works to boost memory by stimulating the brain, ensuring your thoughts are clear and that you can remember things. It also helps to prevent the onset of narcolepsy symptoms such as excessive sleepiness, drowsiness, hallucinations, and cataplexy (partial or total loss of muscle control). This allows people with narcolepsy to wake up earlier, improve their quality of life, and become more productive at work. The upper panels of Figure 1 illustrate that selected cognitive and psychomotor performance measures (e.g., hit latency on the DAT) were altered significantly as a function of shift condition for placebo-treated subjects. The same holds true for subjective ratings of mood and alertness.
3. Reduced stress
Many shift workers experience stress due to erratic sleep cycles, which can lead to problems like fatigue and an inability to focus. Artvigil 150 can help reduce levels of stress, which can enhance productivity and overall well-being. It also helps people with chronic conditions such as narcolepsy, a sleep disorder that causes excessive daytime drowsiness.
Several studies have demonstrated that shift work disrupts cognitive and psychomotor performance, ratings of alertness, and physiological measures of sleep, making workers more susceptible to performance decrements during night shifts. However, little is known about how psychostimulants may interact with these shift-change-related alterations.
This double-blind, within-participant study examined the effects of Modalert on cognitive and psychomotor performance, mood, and measures of sleep during simulated shift work. Volunteers performed computer tasks from 0830–1730 h on three consecutive days under two different shift conditions, day and night, alternating each shift condition three times with an 'off' day between shifts. Participants received placebo or Modalert (200 mg). Mood was assessed using subjective-effect ratings; results showed that Modalert reduced the disruptive effect of night shifts on some ratings of mood but did not affect others, such as 'Alert'.
4. Reduced insomnia
Individuals who work rotating shifts often report sleep disruptions and increased feelings of sleepiness while at work, which may contribute to diminished performance and the occurrence of work-related accidents. The current study was conducted to determine whether the alerting agent Waklert 150 could improve cognitive and psychomotor performance and mood during simulated shift work. Eleven participants completed computerised task batteries in a 23-day residential laboratory setting. They performed computer tasks on three consecutive days under two shift conditions: a day shift from 0830 to 1730 h and a night shift from 0030 to 0930 h, each separated by an 'off' day. Performance decrements associated with shift change, such as reduced learning and visuospatial processing and decreased sustained concentration or vigilance, were observed. Subjective ratings of mood were also disrupted by the shift condition. The upper panels of Figure 2 show selected subjective-effect ratings for "alert" and "sleepy" as a function of shift condition.
The results showed that the administration of a small dose of modafinil significantly attenuated shift-work-induced alterations in performance, ratings of alertness and mood, and physiological measures of sleep. These data are consistent with previous studies demonstrating that the stimulant methamphetamine improves cognitive and psychomotor performance and ratings of alertness during a night shift but not on an off-shift day.
