[header] How to elevate your hand while sleeping [title] Sleep on your back or side.

[header] How to stop eating at night [title] Know the difference between emotional and physical hunger. [step] Sometimes we eat at night because we are genuinely hungry, especially if we deprive ourselves of calories throughout the day. Other times, nighttime eating is due to emotional hunger. <sep> (A) Identifying whether your nighttime eating is physical or emotional is an important step in dealing with the problem. [substeps] Does your hunger come on suddenly or gradually? Emotional hunger is more likely to manifest itself in the form of a sudden craving. (B) For example, when you're caught up on a project, you may think you have to eat too much and constantly think about your dinner plans, and you may let emotional hunger take over.
