Jet lag and blood sugar: How long-haul travel affect glucose levels
Long-haul flights can disrupt the body's internal clock, affecting sleep patterns and meal timing, which may temporarily alter blood sugar levels. Consultant Dietician Kanikka Malhotra explained that this disruption can lead to a short-term dip in insulin sensitivity, causing higher blood sugar spikes after meals. However, chronic circadian disruption from frequent travel could contribute to long-term metabolic issues, including insulin resistance and increased diabetes risk.
