15 surprising things that drain your energy

You’ve probably heard that if you feel hungry, you might actually be thirsty. But did you know that if you feel tired, you might actually be thirsty? Researchers at the University of Connecticut found that even mild dehydration can torpedo energy, especially in women. The reason is unclear, but one theory is that the brain’s primal warning system is letting you know that it needs water to survive. Regardless, it’s important to monitor your water intake – all year round and all day long – because the body often doesn’t realise it’s thirsty until it’s already 1 to 2 per cent dehydrated.
