Establishing healthy sleep habits, or sleep hygiene, is the key to getting a good night's sleep. This includes limiting caffeine intake close to bedtime, and making sleep a priority by leaving parties early or choosing social engagements carefully.
For most healthy adults, guidelines suggest at least seven hours of sleep per night. However, some people may need less than this, while others may need more. The major reason for individual differences is that we often look at sleep the wrong way.
