Dr Lucy Donaldson, Chair of The Physiological Society's Policy Committee, said: "The modern world brings with it stresses we would not have imagined 50 years ago, such as social media and smartphones.
"It was striking that for every single event in this study, from money problems to Brexit, women reported greater stress levels than men. This could have a real impact on women's health.
"While many people are aware of the effect of stress on mental wellbeing, it is also important to consider the impact on the body's systems.
“Your brain, nervous and hormonal systems react to stress and it affects your heart, immune system and gastrointestinal system. When stress is prolonged, these effects on the whole body can result in illnesses such as ulcers or increased risk of heart attack."
