A Duke University research revealed that men tolerate sleep deprivation better than women. When women don’t get enough sleep, they suffer mentally and physically. They are at high risk of developing heart disease, depression, or blood clots, while men suffer fewer consequences.
Heavy sleepers have more brain activity going on while they sleep – the activity drowns out the noises that would wake up most people.
A “lychnobite” is someone who sleeps all day and works at night.
More than one-third of married couples in Canada sleep in separate bedrooms. Sleeping together may actually be bad for your health. Evidence has proved that couples suffer 50 per cent more sleep disturbances if they share a bed.

When you can’t sleep on your first night in a new place, your brain is trying to protect you. Many animals sleep with only half their brain, while the other half stays alert to possible dangers. It’s called the ’first night effect’ in humans, because our bodies put us in a strange, half-asleep/half-awake state the first time we sleep in an unfamiliar environment.
