When my friend has a headache,I will give him some advice to get him well. First,drink more water. Adult humans should drink 2-3 liters (or roughly eight 8oz glasses) of water per day.That is in addition to things like tea and coffee. Second, eat breakfast.A light, healthy breakfast is sufficient enough to reap the benefits of eating early. If it's comprised of lean protein and whole grains, then it will keep you from gorging at lunch. Third,eat well throughout the day. If half of your plate is vegetables and fruit, you're on the right track. Add in lean protein, low-fat dairy, and whole grains. Forth,go meatless. being vegetarian is a good way to reduce your calorie intake and get loads of vitamins and minerals. Fifth,eat at the right times. A good time for a healthy, easy-to-digest evening meal is between 17:00 and 20:00; it's best to avoid late night snacks because they fill you with unnecessary calories and can disrupt your sleep.
