The amount of hours (8-hour versus 12-hour shifts) is also controversial. However, it is common for night shift workers to revert to daytime routines for a day or two during days off, which tends to make the circadian rhythm unstable. It takes about 10 days for the body to adjust to night shift work. Others advocate short rotations of two to three days. Some people advocate prolonged rotation, such as two to three weeks. The frequency of rotation is also controversial. For the most people, rotating forward through day, afternoon and night shift is better than backwards (night, afternoon then day). The best rotating shift pattern is still undecided. It’s difficult to keep the sleep environment dark, free of noise and relatively cool. Night workers can find it difficult sleeping during the day (particularly in Australia). ![]() They often sleep though the day in two split periods, a few hours in the morning and then an hour or so before going to work at night. Shiftworkers get, on average, two to three hours less sleep than other workers. Shiftworkers with diabetes can experience difficulties in controlling their blood sugar levels.Sleep deprivation caused by shiftwork may increase the risk of epilepsy in pre-disposed people.Probable increased risk of cancer, especially breast cancer.Increased likelihood of family problems, including divorce.Higher risk of motor vehicle accidents and work-related accidents.Increased risk of gastrointestinal problems, such as constipation and stomach discomfort.Increased risk of cardiovascular disease.Increased risksĪ person working night shift, which causes disruption to the circadian rhythm, is at greater risk of various disorders, accidents and misfortunes, including: This is one of the reasons why night workers who try to fall asleep at 8am find it very difficult and also find it difficult to remain asleep through the day. As the body temperature rises, it is more difficult to stay asleep. The tendency to fall asleep and stay asleep occurs during the decreasing phase of the temperature circadian rhythm (between midnight and 4am). It reaches the lower level in the early hours of the morning and reaches the maximum level late in the afternoon. This temperature increases through the day. Your metabolism at nightĪn important body function, which follows the circadian rhythm, is the internal body temperature. Research findings are beginning to show that shiftwork can be hazardous to your health. This may put them at risk of health problems. A person who works nights, or starts their working day before 6am, is running counter to their circadian rhythm. This changing rate of activity over each 24-hour period is known as the circadian rhythm. Many other functions of the body – including temperature, digestion, heart rate and blood pressure – fluctuate through the day, tuned by the activity of the circadian clock. This system keeps you synchronised through the day-night cycle. They drop at daybreak and remain low during the day.ĭuring the day, other chemicals (neurotransmitters) – such as noradrenaline and acetylcholine – increase in the body and keep you awake. In the evening, when the light starts to wane, your clock notices and prompts a flood of a brain chemical called melatonin, which gives the body the signal to fall asleep. There is a small part of the brain called the ‘circadian clock’, which monitors the amount of light you see, moment by moment. The sleep-wake cycle appears to have evolved for humans to be awake during the day and to sleep for approximately eight hours at night. ![]()
