1. Drinking Coffee Can Prevent Depression - We hear a lot about the negative effects of caffeine on our health, but it turns out that caffeine has its good points too. Research from the Harvard School of Public Health found that women who drank a minimum of four cups of coffee per day could lower their risk of depression by 20 per cent. Earlier research also found that females who drank two or more cups per day were less likely to commit suicide. 2. Smell An Apple To Prevent Claustrophobia - An apple a day can do more than just keep the doctor away, it can also help with claustrophobia. Apparently smelling a green apple will relieve the stress associated with confined spaces, according to research from the Smell and Taste Treatment and Research Foundation. Sniffing a green apple can also prevent headaches and migraines and some homeowners even use the scent to make their houses seem bigger to potential buyers. 3. Chewing Gum Makes You More Alert - If your suffering from a mid-afternoon slump or can’t seem to concentrate in the morning, then try chewing some gum to make you feel awake. Coventry University researchers found that chewing mint flavoured gum dramatically reduced feelings of tiredness. Another study on the subject found that chewing gum can improve overall test scores and memory by 35 per cent, relieve stress and reduce anxiety levels. 4. If You’re Tired… Exercise - After a long day at work, going to the gym is probably the last thing on your list of priorities but research has found that exercising actually gives you more energy. A study published in Medicine and Science in Sports and Exercise found that levels of fatigue and depression improved after a 30-minute session of moderate intensity exercise. This is because exercise improves your cardiovascular health which means that more blood and oxygen flow around the body, therefore giving you more energy. 5. Handwriting Things Can Help Your Memory - Research from Indiana University found that in order to remember something, you should handwrite notes, rather than type them. Writing is thought to boost your memory as note taking by hand requires different cognitive processes than typing. For example, if in a lecture you are writing notes, you have to listen carefully to what the speaker has said as it is impossible to write down every word. Therefore through this process, you are listening, digesting and summarising the information more effectively than someone who is just typing words into a laptop.
