Researchers Find Outdoor Time Improves Body Image and Short Sleep Leads to Weight Gain

A large international study involving more than 50,000 participants from 58 countries reported that spending time outdoors is linked to greater self‑compassion and a more positive perception of one’s own body. The researchers noted that nature exposure shifts attention from appearance to experience, reduces social comparison, and is associated with higher overall life satisfaction.

A separate investigation published in the Annals of Internal Medicine tracked 95 adults who reduced their nightly sleep by about 78 minutes for six weeks. During the short‑sleep phase participants gained an average of 0.5 kg, saw an increase in waist circumference, and spent 17 minutes more per day in sedentary activities. The effect was strongest among post‑menopausal men and women, suggesting that chronic sleep loss may disrupt energy balance and appetite regulation, contributing to weight gain.
