How do you overcome exhaustion from school. i feel extremely tired and my head is in a fog. when will i get my optimal amount of energy back?

Healthy living: Much of the fatigue/exhaustion students suffer from is related to suboptimal health and/or too much stress. Try to focus on eating well, remaining active, sleeping well(which means both more regular sleeping patterns and sleeping enough), and keeping up good social bonds, in addition to minimizing stress(I know easier said than done). Also try to avoid too much caffeine!

Deprivation: Successful recovery from sleep deprivation can take weeks to months of maintaining a regular bedtime/ wake up schedule, sleeping at least 8 hours per night, avoiding excessive caffeine and alcohol, and getting treatment for any underlying sleep disorder. Unfortunately there is no quick fix and maintaining these habits can be difficult. Try to make it a priority. Best of luck to you

Rest, diet, herbs &: If the exhaustion is actually due to school it is likely related to adrenal fatigue. The best treatments are adequate sleep & rest, stress reduction techniques like meditation & yoga, a healthy low-glycemic diet, good quality multivitamin & herbs like rhodiola & ashwagandha. Homeopathics like Kali phos may help too. See www.adrenalfatigue.org Also see a doctor to rule out other causes of fatigue.
