We often talk about working hard, studying late and chasing goals. But to be your best self, you also need to know when to stop. Sleep isn’t just “doing nothing”. It is the fuel that powers your brain, improves your mood and keeps you healthy.
Whether you are building a better bedtime routine or just describing that amazing feeling of sleeping in on the weekend, you need the right vocabulary.
Here are six idioms, adjectives and other phrases to use when you are ready to recharge your batteries.
1. Burn the candle at both ends
This idiom is about going to bed late and waking up early, usually because you are working too hard or trying to do too many things at once. Imagine lighting both ends of a candle. It gives twice as much light, but it burns out twice as fast.
Example: You’ve been burning the candle at both ends studying for exams and practising for the basketball finals.
2. Hit the hay (hit the sack)
This idiom is a casual way to say “go to bed”. Before modern mattresses, people used to sleep on sacks filled with dried grass, also called hay.
Example: I’m going to hit the hay early tonight because I have a chemistry test at 8am tomorrow.
3. Out like a light
This simile describes people who fall asleep quickly and deeply – usually as soon as their head hits the pillow.
Example: He wanted to watch the film, but he was out like a light five minutes after the opening credits.
4. Groggy
This adjective is about the specific feeling of being dizzy or unable to think clearly because you are sleepy, feel sick or have just woken up.
Example: Don’t ask me any maths questions yet. I just woke up, and I’m still groggy.
5. Catch some Z’s
This informal phrase refers to getting sleep. In comic books, when characters sleep, the letter “Z” floating above their heads represents the sound of snoring.
Example: Do you mind if I close the blinds? I’m going to try to catch some Z’s before the plane lands.
6. Sleep on it
This idiom is about waiting until the next day to make a difficult decision, hoping that a night of rest will give you a fresh perspective.
Example: I’m not sure what class to drop, so I’ll sleep on it and decide in the morning.
