Take care of the basics
If you’re feeling low, the first thing you should do is make sure your body’s fundamental needs are being taken care of.
If you’ve gone a long time without eating, you might have a low blood sugar level. Low blood sugar can leave you feeling more anxious or irritated and can make it harder for you to concentrate.
You might also be dehydrated. Even mild levels of dehydration can impair your cognitive function, especially concentration and memory, so make sure you’re drinking 6 –8 glasses of fluid a day. Water is best, but sugar free drinks, tea, coffee and low-fat milk all count towards your daily intake.
To feel your best, you should make sure you’re eating a balanced diet that contains all the food groups, including five portions of fruits or vegetables a day (which can be fresh, canned, dried or frozen).
