Caffeine is known for its the ability to drive drowsy, but the people who work the night shift, better use other means of ginger itself. Canadian physicians found that use a tonic drink at night can lead to adverse changes in health and well-being.
Therapists University Montreal and the sleep disorders center at the hospital Sacre Coeur conducted laboratory experiment, which was attended by two age groups. The first group They included people from 20 to 30 years, the second - from 45 to 60 years.
Volunteers in both groups We spent two sleepless nights. Coping with sleeping pills helped one group with 200 mg of caffeine, the other - the lactose (to perform the role of placebo). Son received caffeine was not as deep, especially among older participants group who slept for 50% less than usual. In both groups, caffeine reduced efficiency, sleep duration, slow-wave sleep phase and the phase REM sleep. Middle-aged people are particularly vulnerable to the timing signals wakefulness and rest internal circadian rhythms due effects of caffeine.
Thus, experts say, can be considered proven that caffeine prevents the normalization mode sleep and this side-effect worsens with age.

"The older we get, the worse the effect of coffee on our sleep as a whole ", - experts stress.
Middle-aged people are particularly vulnerable to the so-called "synchronization signals awake and resting "internal circadian rhythms of the body is due to the effects of caffeine. Therapists recommended for people older than 40 to reduce consumption of coffee, especially if they They work at night. (READ MORE) Healthy eating
