There are several lifestyle choices, which can contribute to reducing heartburn symptoms.
Reduce stress: Stress can contribute to heartburn.
Exercise regularly: Regular exercise and losing weight can often help and can contribute to you being healthier overall. However be mindful that certain exercises such as stomach crunches can push acid out of the stomach causing heartburn.
Control portions: Reducing portion size and avoiding big meals close to laying down/going to sleep.
Stop smoking: If you smoke, try to cut down or quit as smoking relaxes the valve at the top of your stomach, allowing excess stomach acid to reflux into your oesophagus.
