What time should you go to bed?
Tell it when you wake up. It gives you a bedtime that leaves room for the sleep your age needs, and the time your last meal should be done by.
For your age the app suggests 8 h.
- Go to bed at
- 23:00
- Last meal
- 20:00–21:00
- Two to three hours before bed — that’s where the fast starts.
Why it’s worth it
Steadier days
A full night is commonly linked to steadier energy, mood and focus the next day. It’s the habit the others lean on.
Fewer cravings
Short nights are commonly linked to more hunger and more snacking the next day, which makes eating well harder than it needs to be.
Same time, every night
Regular bed and wake times count, not just the hours. The app scores how regular your nights are alongside how long they were.
Healthness scores every night for you.
Read from Health, never typed in. A score, the stages behind it, and five plain sentences saying which part of the night cost you what.
Is Healthness medical advice? No. It is an educational tracking tool. Fasting is not right for everyone — if you are pregnant, diabetic, on medication, or have a history of disordered eating, talk to your doctor before changing how you eat.
