Hi
I understand your concern.
sleep is very sound if you sleep up to 6 to 7 hours continuously in night.
6 to 7 hours sleep is enough in a day.
6 hours sleep in night is necessary and you have to sleep.
Sleep hygiene is good to maintain by certain routines and lifestyle modification
Fix sleep schedule and stick on it
No day time sleep
Exercise that makes you fatigue
Stress free activities and meditations
Avoid alcohol and smoking
Avoid heavy meal in dinner
Avoid tea coffee soft drink at night
Use bed when you feel sleepy
Read up to when you will sleepy
calm and cool bed room
All of this will help you to restore good sleep.
I hope i have answered your query.
Happy to help you further.
Thank you.
