New Delhi, Nov 20 (ANI): A new study has found that women who go to sleep and woke up at same time every day had lower body fat. Brigham Young University exercise science professor Bruce Bailey studied more than 300 women from two major Western U.S. universities over the course of several weeks and found that those with the best sleeping habits had healthier weight. The study found that getting less than 6.5 or more than 8.5 hours of sleep per night is associated with higher body fat and that quality of sleep is important for body composition. Bailey related consistent sleep patterns to having good sleep hygiene. When sleep hygiene is altered, it can influence physical activity patterns, and affect some of the hormones related to food consumption contributing to excess body fat.
