In spring, it is quite common to catch a flu. If you catch it, you should stay home and get plenty of rest, as well as drink plenty of fluids to make sure you consume enough water to stay hydrated.
In summer, a rash might come to you anytime. What you should do is to avoid scratching the rash because doing so can make it worse and could lead to infection. Go to the doctor if it does not go away or get worse.
In fall, the wind might cause horrible headaches. Try closing your eyes and rest. Massaging your neck and temples might be just as good as a dose of medicine.
In winter, a cold is so easy to get to you. Worry not, just get enough rest, it will soon go away. Some hot tea with ginger can be your best friend at the time.
Good luck.
