Misinformation about sleep often harms our habits more than it helps. Let’s bust five common sleep myths that might be keeping you from the rest you need.
| Myth | The Truth (Expert Perspective) |
| 1. You must get 8 hours of sleep. | False. Individual sleep needs vary widely, typically falling between 7 and 9 hours. Focusing on a specific number often causes performance anxiety. Focus instead on feeling rested when you wake up naturally. |
| 2. Older adults need less sleep. | False. Older adults still need about 7–8 hours. However, as we age, sleep becomes lighter and more fragmented, meaning they often get less sleep, which can lead to fatigue. |
| 3. Alcohol helps you sleep. | False. Alcohol acts as a sedative, making you fall asleep quickly, but it severely disrupts the second half of the night, leading to fragmented, poor-quality REM and deep sleep. |
| 4. Snoring is always harmless. | False. As we discussed last week, loud, habitual snoring is the key sign of Obstructive Sleep Apnea (OSA), a serious medical condition. |
| 5. You can ‘catch up’ on sleep over the weekend. | Partially False. While an extra few hours can help restore alertness, chronic sleep deprivation creates a sleep debt that cannot be fully repaid. Relying on weekend catch-up messes with your body’s rhythm (social jetlag) and has long-term health costs. |
