Altering sleep-wake cycle will have its effect on the body, say experts
Working on night shifts might have become a way of life for many professionals now, but altering the sleep-wake cycle will have its own effect on the body; it could cause a sleep disorder in some. Sleep specialists say that such disorders can be treated by taking simple measures at the workplace and home.
Shift Work Sleep Disorder occurs when the body’s internal biological clock gets altered or confused. While there are many professionals who work at night, it is the employees of the Information Technology sector who are the most affected, mainly due to the regular night shift patterns, say sleep specialists.
IT/BPO sector
“More than 80% of persons suffering from shift work sleep disorder are from the IT and BPO sector. This is because they work in the same shifts, disrupting their sleep pattern,” said N. Ramakrishnan, senior consultant, Sleep Medicine, Apollo Hospitals.
“Most of us go to bed between 9 p.m. and 11 p.m. and wake up between 5 a.m. and 7 a.m. This is the usual sleep-wake up time and socially accepted hours of sleeping. For those with this sleep disorder, the symptoms are like chronic jet lag. Irritability, anxiety and depression are among the symptoms. The hormonal cycle is messed up. We are noticing menstrual irregularities among women and infertility among men,” he explained.
Lifestyle problems
There is the risk of lifestyle-related health problems. High blood pressure, diabetes, obesity, early heart disease and stroke are common, Dr. Ramakrishnan of Chennai said.
Koushik Muthuraja, consultant, pulmonologist and sleep specialist, Sri Ramachandra Medical Centre, said, “We have the circadian rhythm that is considered to be our bodies’ internal biological clock. This clock on a 24-hour basis regulates certain changes in our body, such as hormonal secretions, temperature regulation, sleep timing and other physiological changes. When people work at night continuously, the biological clock gets confused.”
As a result, a majority of night shift workers present themselves with complaints, he said.
Dr. Ramakrishnan said the treatment included a review of the entire cycle.
“A significant amount of counselling is involved. We tell them to ensure appropriate light and dark exposure. They should ensure that their workplace is appropriately lit at night time. When they go back home, they should avoid driving and instead take a car pool. They can use eye shades. They should eat light and make their room conducive. Occasionally, we use melatonin for treatment,” he said.
