Today is Monday and I am feeling particularly sleep deprived. On that note, here are some recent studies relating sleep, health and longevity.
Nighttime light linked to cancer
" The findings of the study, which combined satellite images with local breast cancer statistics, support the theory that too much light at night raises the risk of breast cancer by interfering with the production of melatonin, The Washington Post reported Wednesday.
The researchers found the breast cancer rate in areas with average night lighting to be 37 percent higher than in communities with the lowest amount of light. "
Daytime Dozing Stroke Warning
"These included while watching TV, sitting and talking to someone, sitting quietly after a lunch without alcohol and stopping briefly in traffic while driving.
The risk of stroke over the next two years was 2.6 times greater for people who reported "some dozing" compared to those with no dozing.
Among those who reported "significant dozing" the risk was 4.5 times higher.
Previous research has shown that people who suffer from sleep apnoea - short periods when breathing stops during sleep - have an increased stroke risk.
It could be that daytime sleepiness is a sign of sleeping poorly at night because of sleep apnoea.
Every year around 150,000 people in the UK have a stroke. "
Sleepers blood pressure at risk from jet noise
"Volunteers' blood pressure increased after exposure to a noise louder than 35 decibels - whether it came from overhead aircraft, or snoring."
"Aircraft noise caused an average increase in systolic blood pressure of 6.2 mmHg and an average increase in diastolic blood pressure of 7.4 mmHg."
"The researchers have calculated that for every extra 10 decibels of aircraft noise the risk of hypertension is increased by 14%."
There is no such thing as a good night's sleep
"Those who changed their sleep habits by cutting the time in bed from 7 to 5 or less hours were 1.7 times more likely to die, and twice as likely to die from cardiovascular problems."
Early rising no good for the heart: study says
"You can use those weekends to get some recovery sleep," she said. "It does seem to be, that certainly for your cognition and memory and reaction time, all those things can recover quite quickly, but you have to give yourself that good opportunity for sleep."
