Weight


Weight, Sleep-Research

There is a strong connection between sleep and weight. Studies have shown that people who get 6 hours of sleep are less likely to be overweight or obese. This is likely due to several factors, including:

  • Hormonal changes: Sleep deprivation can lead to changes in hormone levels, including an increase in the hormone ghrelin, which stimulates appetite, and a decrease in the hormone leptin, which suppresses appetite. These changes can lead to increased food intake and weight gain.
  • Metabolism: Sleep deprivation can also slow down metabolism, which can make it more difficult to lose weight.
  • Physical activity: People who are sleep-deprived are more likely to be inactive, which can lead to weight gain.

The 2018 study “Why 6 hours of sleep is optimal” found that people who got 6 hours of sleep had lower levels of body fat and were less likely to be overweight or obese than those who got less or more sleep. This study adds to the growing body of evidence that suggests that getting 6 hours of sleep is important for maintaining a healthy weight.

If you are trying to lose weight or maintain a healthy weight, getting enough sleep is essential. Aim for 6 hours of sleep per night and make sure to get regular exercise and eat a healthy diet.
