Everyone who drinks too much knows the unpleasant flip side of a night on the tiles – the dreaded hangover.
That horrible morning-after feeling can range in strength and intensity and vary from person to person, but it usually involves a banging headache, sickness, dizziness, dehydration, mild diarrhoea, tiredness and weakness.
A hangover can also leave you struggling to concentrate, irritable and sensitive to light for a prolonged period after your last drink – not a good combination if you want to enjoy the next day and not spend it suffering in bed.
The principal cause is ethanol – the alcohol in your drinks. It is a toxic chemical that works in the body as a diuretic, causing the headache, dry mouth, dizziness and constant nausea. Your hangover eases as the body turns the ethanol into a less toxic chemical. The other factor that affects a hangover is the type of drink you have been downing. Dark drinks tend to make hangovers worse. So does mixing drinks.
