ALCOHOL is a poor nightcap and robs sleep of its restorative powers, research shows.
A study of 10 students found late drinking lead to sleeplessness and exhaustion.
Alcohol was found to suppress parasympathetic nerve activity -- the part of the nervous system that slows the heart rate and aids digestion.
The parasympathetic nerve circuit helps maintain and restore energy.
The findings were published today in the journal Alcoholism: Clinical & Experimental Research.
Mum's weight affects asthma
OVERWEIGHT mums could be more likely to have asthmatic children.
Women who are overweight or obese before they become pregnant are between 20pc and 30pc more likely to have teenagers who wheeze or have asthma.
The heaviest women in the study -- who weighed between 62kg and 130kg -- were much more likely to have children with wheezing symptoms, said study author Professor Marjo-Riitta Jarvelin, from Imperial College London.
