The Science of Better Sleep

Understand Your Sleep, Restore Your Energy and Protect Your Long-Term Health

Do you struggle to fall asleep, wake repeatedly during the night or feel exhausted despite spending enough time in bed?

Poor sleep can affect far more than your energy. It can influence your memory, concentration, mood, appetite, productivity, relationships and long-term physical health. Yet many people continue to live with disturbed sleep without understanding what is causing it—or what they can realistically do about it.

The Science of Better Sleep is a practical, doctor-led guide that explains the fascinating science of sleep in clear, accessible language.

Written by Dr. Prince D Costa, this book takes you inside the sleeping brain, explains why restorative sleep is essential and shows you how to build healthier habits without relying on misleading quick fixes.

Inside the book, you will discover:

• What happens inside your brain and body while you sleep
• The roles of light sleep, deep sleep and REM sleep
• How much sleep you really need at different stages of life
• Why sleep deprivation affects memory, mood and decision-making
• How poor sleep may contribute to high blood pressure, weight gain, diabetes and weakened immunity
• The relationship between sleep, emotional health and dementia risk
• Why good sleep supports learning, creativity and productivity
• The most common causes of insomnia and unrefreshing sleep
• How stress, anxiety, caffeine, alcohol, smartphones and shift work disrupt sleep
• Warning signs of sleep apnoea, restless legs syndrome and other sleep disorders
• Evidence-based ways to improve sleep naturally
• How Cognitive Behavioural Therapy for Insomnia can help persistent sleep problems
• What you should know about sleeping tablets, melatonin, magnesium and herbal supplements
• The benefits and limitations of sleep apps, trackers and other technology
• How to create a personalised, sustainable sleep plan

Unlike books that promise a miracle cure, The Science of Better Sleep focuses on understanding the cause of poor sleep and making practical changes that can be maintained over time.

The book also includes a Seven-Day Sleep Diary, guidance on when to seek medical help, and a structured Thirty-Day Better Sleep Programme to help you turn knowledge into action.

This book is ideal for people experiencing insomnia, daytime tiredness, poor concentration or irregular sleep—as well as shift workers, busy professionals, students, parents, older adults and anyone interested in protecting their brain and long-term health.

You do not need any medical or scientific background. Complex ideas are explained using relatable examples and straightforward language, allowing you to understand your sleep and begin improving it immediately.

Better sleep is not wasted time. It is an investment in every hour you spend awake.

Start your journey towards deeper rest, greater energy and a healthier life today.
