Ali Cullen, nutritional therapist at A.Vogel, says: “Food plays an important role in helping you feel better and lighten your mood. If you’re eating more sweet foods, your blood sugar levels are constantly rising and falling which may leave you feeling irritated and low on energy.
“Avoid refined sugar and increase the amount of wholefoods you eat to reduce mood swings and maintain a healthy blood sugar level.
“Nuts, seeds and wholegrains contain magnesium which is good for your nervous system, as are green leafy vegetables which are packed with B vitamins.
“Try and get out into the fresh air as much as you can to ward off the low moods. Taking a walk on your lunch break is a good way to get a healthy dose of natural light.
“Cardiovascular exercise releases feel-good hormones and gets you outside so the more exercise you do, the better you feel. Be careful to take it one step at a time, don’t overdo it.”
