You can become dehydrated very quickly in a centrally air-conditioned office. Depleted fluids levels lead to fatigue, so you should reserve a space on your desk for a bottle of water. Take regular sips throughout the day aiming to drink about eight glasses.
Clear your drawers of junk foods such as sweets and chocolate bars as these are the foods you should avoid if you want to stay in good shape. Buy an air-tight box with a snap-on lid and stock your favourite healthy snacks in it. Try mixed nuts (such as walnuts and almonds), dried fruit, small sesame bars, sunflower and sesame seed or also some muesli to bridge the hunger gap if you forget to have breakfast before leaving for work.
You may also keep supplies of your favourite alternative remedies in your desk. A small bottle of essential oil of lavender helps to reduce tension headaches. Sachets of herbal teas such as chamomile, fennel and mint help with digestive problems and rosehip boosts your vitamin C levels. Herbal teas are low in caffeine and make good alternatives to endless cups of coffee.
Get into the habit of taking fruit to work with you everyday. An orange, apple and banana and a few grapes make great desk snacks.
Make your own sandwiches to bring to work if you have the time. They are a healthy and delicious breakfast meal. Try out various breads such as ciabatta, foccacia or wholemeal roll.
