1. Links Between Stress Shift Work And Serotonin Levels
The 21st Century is best characterized by the advent of ultra-modern technology, global
commercial and business, and the unstoppable desire to get and stay ahead. Because of
these factors, business corporations compete in a world where the economy is active 24
hours a day, seven days a week. This phenomenon created a demand for employees that
would work even during the night upto the wee hours of the morning. This work schedule
reversed employee lifestyle, making the day their time to for sleeping. Shifts may disrupt the
normal body functions, hamper sleep cycles, and reduce the body’s serotonin levels.
Serotonin is a neurotransmitter that is found in the central nervous system and impacts
multiple functions like mood, sleep, sexuality, and appetite. This neurotransmitter may also
promote cell regeneration.

Studies show that non-day shift workers tend to have lower levels of “feel-good” hormones
called serotonin. Researchers at the University of Buenos Aires led by Dr. Carlos J, Pirola
studied 683 men and compared 437 day workers to 246 shift workers. The results, the shift
workers’ serotonin levels, measured through blood tests were significantly lower than those
on regular day schedules. In addition to reduced serotonin levels, shift workers were also
found to have higher cholesterol, hip-to-waist ratios, increased blood pressure, and higher
triglyceride levels.

Because serotonin levels administer sleep patterns and other body functions, the University
of Buenos Aires study suggested that shift work may also lead to a so-called Shift Work
Sleep Disorder. People with this disorder tend to remain awake when they should be
sleeping. These individuals can be very tired during waking hours. This disorder takes place
because of a work schedule that takes place during the normal sleep period. Because of
this, people who have difficulty getting sleep because their bodies are still programmed to be
awake. The time of being asleep and being awake is different from what the body’s internal
clock expects.
Other studies also found out that non-standard and night shift work may affect the
cardiovascular and metabolic systems. These studies suggest that there is a possibility that
shift work is directly responsible for high blood pressure and increased body fat, according
the researchers of the Buenos Aires study. In addition to the disruption of sleep patterns,
reduced levels of serotonin are also linked to other conditions like stress, anxiety, and
depression.

Lifestyle changes can lead to improved serotonin levels. To make serotonin levels
consistent, sleep patterns should be consistent and food regimens should include necessary
2. vitamins and minerals to control the serotonin levels. Certain drugs and substances like
caffeine, nicotine, alcohol, and antidepressants should be avoided because they may
deplete serotonin production.

Individuals who want to improve their serotonin levels can use medication to aid them in their
goal. The amino acid 5-HTP can be taken as a supplement and improve the body’s ability to
manufacture serotonin. Another amino acid called L-tryptophan is used by the body to
produce serotonin. However, before taking these supplements, patients are advised to seek
the approval of doctors and other health professionals. Individuals who choose to work in the
night should maintain adequate rest to lessen ill-effects that may develop. Healthy lifestyles
and nutritious food regimens may improve serotonin levels and improve one’s quality of life.
