Even though a recent study can’t determine causation, I think that it is important to note the relationship demonstrated between “social jet lag” and BMI (body mass index). Many of us scrimp on sleep and for whatever reason it’s seen as a bit of a badge of honour rather than the unhealthy practice that it truly is. You may eat a healthy diet and exercise regularly but you’re still hurting your health if you’re not getting enough sleep. Everybody has different sleep needs, but the average for an adult is 7-9 hours a night. Sleep is when our bodies have the opportunity to repair themselves and rejuvenate. If you’re not getting enough sleep you’re not going to be at your best both mentally and physically. If you’re concerned about your weight then you should add getting enough sleep to your to-do list. There’s no shame in taking care of yourself.
