At least for women.
A lot of people nowadays are choosing to work night shifts as these time usually have higher pays. Some likes it for they're just not keen on nine-to-fives; others just want the time during the day to get on top of errands.
However, all these may sound good but graveyard shifts have its consequences...to your health.
A new study of Dr Xuelei Ma, an oncologist from West China Medical Center at Sichuan University found that women who work night shifts are 19 percent more likely to develop cancer.
Together with her team, they did a meta-analysis at 61 articles involving 114,628 cancer cases and 3,909,152 individuals living in North America, Europe, Asia, and Australia to find out if long time night shift work can increase the risk of women getting 11 different types of cancer.
With this, they found that those women who had late-night occupations for a long duration have a 41 percent greater risk of developing skin cancer, 32 percent greater risk of breast cancer, and 18 percent greater risk of gastrointestinal cancer. What's worse? Continuing it increases the likeliness of having breast cancer by 3.3 percent every five years!
This is in line with previous studies showing that exposure to light at night can increase one's risk of having breast cancer. This is especially true for those who lack melatonin production by the pineal gland, consequently increasing the release of estrogen near the ovaries.
A more recent study looked particularly into female nurses alone. Results showed that, indeed, those who have worked night shift for a long period of time had a 58 percent higher risk of breast cancer. Moreover, there's also a 28 percent increase in risk of lung cancer and a 35 percent increase in gastrointestinal cancer!
Ma also noted in a statement: "Nurses that worked the night shift were of a medical background and may have been more likely to undergo screening examinations. Another possible explanation for the increased cancer risk in this population may relate to the job requirements of night shift nursing, such as more intensive shifts."
