Getting More Sleep Can Reduce Food Cravings

There’s a connection between sleep and hunger. Getting better quality sleep may help with appetite, cravings, and ultimately, weight loss

Have you ever noticed that you feel hungrier or have uncontrollable cravings for certain foods after a poor night’s sleep? It’s not just your imagination—there’s a link between sleep and hunger.

Studies show that even a single night of sleep deprivation changes the levels of our hunger and appetite hormones, leading to increased hunger. It also affects the way your brain’s motivation centers respond to the sight (or even the thought) of food.

They found that when people got more sleep, they were less hungry during the day. Even better, they experienced reduced desire for sweet and salty foods.

Perhaps this is the motivation you need to finally get serious about improving your sleep habits. But how?

The first step involves a set of practices collectively referred to as “sleep hygiene.” If that doesn’t help, there are some more intensive approaches you can try. But let’s start with the basics.
