According to gastroenterologists cited by EatingWell, the morning is often the best time to have a bowel movement.
The body’s natural rhythm, breakfast, and overnight fasting all play a role in digestion and bowel activity.
Morning is often the best time
Experts say that most people find it easiest to have a bowel movement in the morning shortly after waking up.

Digestion follows the body’s natural circadian rhythm, which affects bowel activity throughout the day, according to a study published in Frontiers in Physiology.

The bowel is most active in the morning
The colon is typically most active during the morning hours, which can make it easier to have a bowel movement.
Cortisol may stimulate digestion
The body’s natural cortisol levels rise in the morning and may stimulate the urge to have a bowel movement, according to a study published in the International Journal of Environmental Research and Public Health.
Overnight fasting helps the body
The digestive system works more slowly during sleep, allowing stool to build up in the intestines overnight.
Breakfast activates the bowel
When the stomach is filled with food and drink, the so-called gastrocolic reflex is activated, encouraging the bowel to move.

Fibre plays an important role
A fibre-rich diet can help stool move more easily through the intestines and support regular bowel movements.
Hydration is essential
If the body lacks fluids, stool can become hard and more difficult to pass.
Exercise can support digestion
Regular physical activity can increase bowel activity and make it easier to have a bowel movement.
Travel can affect the stomach
Time zones, changes in eating habits, and reduced activity while travelling can make it harder to maintain regular bowel movements.

Stress can change toilet habits
Stress and anxiety can affect the connection between the brain and the gut, leading to both diarrhoea and constipation.
Certain illnesses can affect bowel movements
Conditions such as irritable bowel syndrome, Crohn’s disease, diabetes, and thyroid disorders can alter bowel habits.
Medication can change digestion
Some types of medication, including opioids and certain antidepressants, can lead to constipation.
Pregnancy can slow digestion
Hormonal changes and pressure from the foetus can make it more difficult to have regular bowel movements during pregnancy.

Age affects digestion
Digestion often slows with age, and the muscles in the intestines and rectum may become weaker.
Good morning routines can help
Experts recommend consistent sleep habits, morning light exposure, water, coffee, and a fibre-rich breakfast to create a stable routine.
The body can be trained to follow regular toilet habits
By sitting on the toilet every morning after coffee and breakfast, the body can adapt to a regular schedule.
Regularity matters more than timing
Experts emphasise that the most important factor is not exactly when you have a bowel movement, but that bowel movements are regular and feel complete.
