"Not enough shut-eye makes you more impulsive and can fuel addiction," the Mail Online reports. The claim was prompted by a review of evidence into the link between sleep and self-control carried out by American psychologists.
The authors looked at previous research, including studies into how poor sleep affects our blood sugar regulation and apparently exhausts our internal resources and willpower. They suggest poor sleep could extend into poor health and how we function at work, and could even fuel addictive behaviours.
