Avoid breast cancer. Sleep in the dark…:
Repeated studies have shown that night-shift workers — such as nurses or air stewardesses — are up to 60 per cent more likely to get the disease. Another found that women who stayed up late two or three times a week were similarly susceptible. Conversely totally blind women are half as likely to succumb to it.
A recent study implies that a good night’s sleep fights cancer:
In the new study, scientists grafted human breast cancer tumours on to rats and infused them with blood taken from women during the day, in the early hours of the morning, and after being exposed to light at night. The blood taken in darkness slowed the growth of the cancers by 80 per cent, but the blood taken after exposure to light accelerated it.
