Self-care does not and should not be limited to a hashtag on Sundays. There are daily habits to help us look after our health mentally, emotionally and physically.
Make your bed.
Use a traditional alarm clock and turn off your electronics at night.
Change your sheets once a week. Nothing like crisp clean sheets to fall into.
Journal daily for 10 minutes.
Get enough rest.
Drink 8 glasses of water or 64 oz a day.
Go for walks and study nature.
Breathing exercises in the morning and evening.
It is said it takes an average of 66 days to form a new habit so why not take one of these ideas and try to be consistent with it. Be patient, Rome wasn't built in a day!
