How much sleep do I need, and how do I stay healthy during preparation?
Aim for 7–8 hours of sleep — it's when memory consolidates. Add basic exercise, real meals and short breaks. Health isn't the opposite of studying; it powers it.
Sleep is when your brain files away what you learned — cutting it to cram is counter-productive and slows recall. Protect 7–8 hours a night, ideally on a regular schedule. Support your brain with proper meals (not just tea and snacks), plenty of water, and 20–30 minutes of daily movement (a walk, stretching, any sport) to reduce stress and sharpen focus. Take short breaks between study blocks and give your eyes rest from screens. Burnout from ignoring health costs far more time than the health habits ever 'take away'.
Memory tip
Sleep consolidates memory — an all-nighter trades tomorrow's recall for tonight's cramming.

💙 For parents
A child who skips sleep and meals to study is not being more sincere — they're quietly lowering their own scores. Gently enforce sleep and mealtimes, and encourage a little daily physical activity. A healthy routine is one of the best gifts you can give their preparation.
