How to stay healthy despite working night shifts

Working the Night Shift? How to Cope?


Night shift?? Nightmare!!!!



The mere mention of “Night Shift” conjures up horrific images of a nightmare. Unfortunately, night shifts are a part and parcel of today’s fast life in the working atmosphere - be it Call Centers, BPOs or even software companies, which need people working nights to provide technical expertise/troubleshooting for their clientèle abroad. On the brighter side, people working night shifts take home a heavier pay package.

Night shifts can have a negative impact on a person as they affect sleep patterns, eating habits. In the long run, nightshifts can cause physiological disorders like obesity, gastric problems, diabetes, backache, headache and infertility. Night shifts can also lead to psychological disorders like depression, fatigue, behavioral changes, mood swings, anxiety, frigidity and impotence. Drinking innumerable cups of coffee/tea adds to the problem of sleep irregularities.



The body secretes certain hormones like adrenaline, which it requires, to cope with stressful situations. These hormones are secreted more during the daytime and less during nights, and this is one of the reasons for night shifts taking a toll on a person’s physical and mental well-being. Furthermore, the secretion of an endocrine hormone called melatonin (commonly called “hormone of darkness”) by the pineal gland, which is very vital for the agility and alertness of mind and body, is hampered when one works at night, as darkness is essential for the optimum production of this hormone. The secretion of melatonin is at its highest in the middle of the night and then gradually lessens during the second half of the night. Unfortunately, a night shifter is up and about during these hours and this leads to further hormonal disturbances.



Night shifts basically call for a complete changeover in the biological clock as people working in the nights have to sleep during the daytime - (when their family members and other people are up and about and working) and work at nights (when their family members and the others are cozily snuggled in their warm beds) – a complete opposite in life styles. This necessitates a total change in thinking too, as one has to be alert at night. The job maybe very challenging and stimulating and the person would have to be in top form both physically and mentally to meet the day’s (night’s) challenge.

One needs to condition one’s mind to prepare for and accept the physiological changes that occur both in the body and mind when they accept a night shift job say at a call center.


For a person to be very alert, agile, positive and ready to face the night’s challenge at work, a few basic habits could be ingrained into the daily lifestyle of the person.




These small lifestyle changes could go a long way in making you a productive and friendly employee. Following stress-relieving techniques advocated by Yoga and other disciplines could help you cope better with night shifts.

Happy Night Shifts!


Night shifts can raise risk of heart attacks and strokes by more than 40% Researchers analyzed the results of 34 studies involving two million people

·         Shift work can dramatically increase the risk of heart attacks and strokes, warn researchers.

·         A study of two million people found shift workers are almost 25 per cent more likely to suffer.

·         Night shift workers run the highest risk of 41 per cent, says a study published on the British Medical Journal website bmj.com.

·         People working shifts also have higher levels of unhealthy behaviors such as eating junk food, sleeping badly and not exercising, which are linked to heart problems.


But researchers said they took this into account - and the excess risks remained.

The latest study is the biggest analysis of shift work and likelihood of vascular problems including heart attacks, strokes and angina. Shift work has long been known to disrupt the body clock and be linked to high blood pressure, high cholesterol and diabetes, but the overall impact on cardiovascular health has been unclear. A team of international researchers analyzed the results of 34 studies involving 2,011,935 people to investigate whether shift work was associated with major vascular events.


Shift work was defined as evening shifts, irregular or unspecified shifts, mixed schedules, night shifts and rotating shifts, and the studies also contained day workers or the general population for comparison.


Altogether 17,359 had some kind of coronary event, 6,598 had heart attacks and 1,854 had ischemic strokes caused by lack of blood to the brain.

These events were more common among shift workers than other people. Shift work was associated with a 23 per cent increased risk of heart attack, 24 per cent rise in coronary events and five per cent extra strokes. These risks remained consistent even after adjusting for factors such as study quality, socioeconomic status and unhealthy behaviors in shift workers. Night shifts were linked with the steepest increase in risk of 41 per cent for coronary events. However, shift work was not associated with increased death rates from any cause.


Daniel Hackam, Clinical Pharmacologist, Stroke Prevention & Atherosclerosis Research Centre (SPARC), London, Ontario, Canada, said the relative risks might appear modest, but millions of people do shift work which means the overall risks are high. He said screening programs could help identify and treat risk factors, such as high blood pressure and cholesterol levels. ‘Shift workers should be educated about cardiovascular symptoms in an effort to forestall or avert the earliest clinical manifestations of disease’ he added. There has been mounting evidence that night shift working might boost cancer risk because of the disruption to the body clock and hormone production. Previous research found a link between night shifts and increased risk of breast cancer in women.

At home


Have dinner at least 3 hours before the shift begins.

Reason: In 3-4 hours, the food is almost digested, even a reasonably heavy meal, so there’s less chance of you feeling heavy or drowsy.


After returning from work don’t jump into bed immediately. Sit and relax for a half hour, watch TV or read a book before going to sleep.

Reason: Your body needs some time to get into comfort mode; plus it will also give your body-clock some time to adjust.


Draw the curtains, shut out all light from the room before sleeping.

Reason: Most people’s bodies are programmed to stay awake during daytime; so sleep doesn’t come easily in the mornings.


A slightly audible drone in the room, like that of a whirring fan or the ac, can help induce deeper sleep.


Switch off your mobile phone and tell the family not to disturb you for 6 or 8 straight hours.

Reason: you require at least 3 to 5 hours of uninterrupted sleep to allow the body to be fully refreshed and recharged for another day’s work.


Soon after waking, go out for a brisk walk of about 30 minutes, everyday.

Reason: Brisk walking is known to boost your metabolism, recharge your lungs. Make it your staple dose of daily exercise


At work

Restrict yourself to 2 or maximum 3 meals, none of which should be heavy. Remember these keywords: “High-fiber, Low-sugar, High-protein Low-fat’

Reason: Heavy meals, especially comprising high-fat foods like cheese, egg-yolk, red-meat, foods cooked/fried in fatty oils will tend to make you sluggish. Sugary foods/beverages will unnecessarily pile on the bulge as you get less exercise

 (unless you’re a cop or a nurse on night duty).


Go easy on sugary drinks, like colas, juices – just one should be enough during the whole 7-8 hours shift

Reason: same as previous point.


Use break-time to run up & down a flight of stairs or use the company gym.

Reason: working your lungs and the consequent surge of oxygen will charge you up for another 4-6 hours of work.


Use the gym to also do the yogic ‘shavasana’ in a quiet corner.

Reason: It will relax you completely and prepare you for another 4-6 hours of work.


Leave your seat and walk every hour or so. Do simple stretching exercises if you can. Try this: Stand erect and then bend forward (slowly) as if to tie your shoe laces. Do not bend your legs while doing so.

Reason: It will avoid the stiffening of muscles and limbs.


Limit your tea/coffee intake – in the entire 24 hour cycle, one should have a fixed quantity (or less, but never more) of tea or coffee. During the nightshift, one should never exceed 3 cups. Even 3 is a little too much but in a stressful job such stimulants do keep you alert the whole time.

Reason: Tea and coffee are both addictive and can make you dependant on them.


If available, have green tea immediately after the small meal you take.

Reason: This is a great anti-oxidant and has many other benefits. It also leaves you feeling satisfied after the meal.


Drink 4 to 6 glasses of water (warm water, if possible)

Reason: It is necessary to hydrate oneself during those 6 to 8 hours as the body loses moisture. If you neglect this aspect, the poor supply of water will result in dry, scaly skin, to begin with, which eventually turns to wrinkles. Warm water does wonders to your digestive system and skin.

Opt for forward change in shifts: If you have a choice of shifts, choose a shift that starts later, rather than before your current one. E.g. if you’re doing a night shift, the next shift should be one that starts early morning (if commuting is not an issue) rather than one starting in the afternoon and ending at night. Reason: This makes it easier for the body clock to adjust.



Sweets, chocolates and other confectionary

Fried foods, packed snacks like biscuits, chips, etc.

Smoking, Alcohol, Stressful situations like arguments and fights

REASON: If you wish to remain fit despite the stress of working odd hours, it’s only smart to avoid things that will either slow you down or create unmanageable health issues.
