4. You Probably Weren't Awake All Night
You might be familiar with this: nights that seem endless, where you just can't fall asleep. Every time you check the clock, you feel more frustrated. "I saw every hour on the clock last night," you tell your coworkers the next day. But we have good news: that's not true. You may think you were awake all night, but in reality, you likely spent most of the night in light sleep. During light sleep, you can still hear, think, and smell. Because of this, it can feel like you're awake, but you're actually resting without realizing it.
