Eat well. If your diet is full of junk food, then your immune system won’t be able to fight against illness and disease as well as it should be able to. Make sure you eat at least 5 portions of fruit or vegetables every day, paying special attention to those containing vitamin C, such as oranges and tangerines.
Spend time in the sunlight. Vitamin D, which our bodies absorb from sunlight, helps our immune system to keep fighting, so you should try to spend some time in the sun whenever you can. Make sure that you wear sunblock though, as not all of the sun’s rays are helpful to us.
Exercise. It has been clinically proven that doing just twenty minutes of exercise three times per week can help to boost our immune system. This is good, as it means that you are getting fitter as well as improving your defences against disease.
Get enough sleep. You would be amazed with the amount of people who get around five hours of sleep per night and think that it is enough. The average adult needs at least eight hours sleep per night in order for their body to repair any cell damage that had been done during the day. If you get less than this, then your body never has the chance to recover back to its full potential.
