One of the most important things we can do is sleep well. Sleep is important as it allows the body to re-cooperate and repair itself. The best way to ensure you get the amount of sleep you need (this varies between person to person, however it is usually around 8 hours) is to go to bed and wake up at the same time every day, or at least as much as you can, avoid alcohol and caffeine so to make sure you are not majorly affected by these as they can disrupt sleep, have a relaxing bedtime routine (I personally enjoy having a bath with Epsom salts that detoxifies the body and relaxes your muscles or read a book), don't use electronic devices 30 minutes before bed and make sure your bedroom is slightly cool, quiet and your bed is comfortable.
Eating well ensures that your body gets what it needs to function correctly. I try to make sure I eat a variety of foods and get a variety of different coloured veges and fruit on my plate, I also use the food pyramid as a guide on how much of a certain food group I consume. The best way to eat is to eat more kilojoules during the start of the day and less nearing the end of the day as your metabolism is faster at the start of the day. It is best to eat snacks between meals as this helps to keep your metabolism steady and may help you eating more because you are very hungry when it comes to meal time.
I know that social interaction is difficult with those on the spectrum as I struggle almost daily with interacting with people however it is still just as important for us Aspies to get a daily dose of connecting with other people. Attending an Aspie social group, joining a (or a few) facebook groups and engaging in the discussions and volunteering are all good ways of finding an opportunity to connect with people.
Exercising (my personal favourites are swimming and walking) helps with keeping your weight under control, improves mood (it works wonders to go for a session to make you feel less angry or upset) and assists with sleep. Aim for at-least 30 minutes a day and you will notice a positive difference in yourself if you don't regularly exercise.
I'm sure there are other things that are great for your health. If you have any thing to add that you do yourself please write in the comments below and thanks for reading my blog.
