Cortisol from prolonged stress signals the liver to release stored glucose, causing persistent spikes. Daily relaxation practices can help regulate both  stress and sugar levels

Sleep Deprivation

Poor or insufficient sleep can make your body insulin-resistant overnight. Stick to consistent sleep schedules and limit screen exposure before bedtime to improve glucose control

High-Intensity Exercise

Vigorous workouts temporarily raise blood sugar as your body fuels muscle activity. Balance intense training with moderate activities like walking or  yoga for steady control

Mild Illness

Even minor infections make your immune system demand more glucose for energy. Stay hydrated, rest well, and track sugar levels until fully recovered

Hormonal Changes

Menstrual cycles, perimenopause,  and menopause can reduce insulin sensitivity. Tracking symptoms  with  your cycle helps identify patterns and  manage glucose changes more effectively

Dehydration

Low fluid intake thickens blood, concentrating glucose. Drinking  enough water daily supports kidney function and helps flush excess  sugar from your system naturally

Pain or Injury

Physical pain triggers stress hormones that raise blood sugar. Manage pain promptly with medical care, gentle movement, and rest to prevent  prolonged spikes

Cold Weather

Sudden temperature drops can increase blood sugar as your body works harder  to stay warm. Dress appropriately and monitor glucose in colder conditions

Medication Side Effects
