Inadequate sleep – of either duration or quality – affects many of us and the health costs are significant, says sleep scientist Dr Gemma Paech. Chronically poor sleep weakens the immune system, reduces memory and attention span, and increases the likelihood of conditions such as depression, type 2 diabetes and heart disease.
The good news is better sleep may be one of the simplest wellbeing hacks we have at our disposal. Even better, getting more of it or improving the quality of it rarely requires spending money or doing much more than making some simple adjustments.
