Sleep deprivation leads to weight gain
Good sleep is very important for you. In previous studies we have seen how sleep deprivation can affect your health and increase your risk of developing many diseases. A lack of sleep has also been linked to weight gain and now a new study provides important information about this outcome.
A study from researchers at the University of Arizona Health Sciences found that sleep deprivation can lead to junk food cravings at night, resulting in unhealthy snacking. This behaviour can lead to weight gain.
About 60 per cent of participants reported that they snacked regularly at night and two-thirds reported that a lack of sleep led them to crave more junk food.
In this study, researchers conducted a nationwide, phone-based survey of 3105 adults. Participants were asked if they regularly consumed a snack at night and whether a lack of sleep led them to crave junk food. They also were asked about the quality of their sleep and existing health problems.
About 60 per cent of participants reported that they snacked regularly at night and two-thirds reported that a lack of sleep led them to crave more junk food. The researchers found that junk food cravings were linked to an increase in the likelihood of night-time snacking — which was associated with an increased risk of developing diabetes. They also found that junk food cravings were driven by poor sleep quality, and that these junk food cravings were associated with a greater likelihood of participants reporting obesity, diabetes and other health problems.
This study shows how sleep quality and eating patterns work together to promote good health. While eating a healthy diet is considered a key factor in taking care of your health, getting a good night’s sleep regularly is also as important. If you find that you are craving snacks at night, then make sure you are doing everything you can to restore your sleep quality so that your health is not negatively affected.
