Yes, research suggests that it can run in families. Genetic factors may influence how the brain regulates sleep, increasing one’s risk. However, lifestyle and environmental factors often play a larger role, meaning good sleep habits can still help manage or prevent Insomnia even if it runs in the family.
Can exercise timing affect Insomnia?
Yes, exercising too close to bedtime may overstimulate the body, making it harder to fall asleep. High-intensity workouts are best done at least 3 hours before sleep. However, yoga or stretching in the evening, however, can support relaxation and help improve sleep quality.
Is it safe to use sleep tracking apps for Insomnia?
Sleep tracking apps can provide helpful insights, but they’re not always accurate and may cause sleep-related anxiety (called Orthosomnia). If they cause stress or obsession with sleep data, it’s better to consult a professional rather than rely solely on technology for managing sleep problems.
Can noise pollution cause Insomnia?
