Workout in the morning
Avoid working out before bed, even if a sweaty workout normally helps you sleep.
By exercising before bed, you raise your core body temperature and will make the heat even harder to deal with.
If you want to work out on a hot day, do it in the morning or at least a good few hours before bedtime.
Watch what you consume
Throughout the day make sure you are drinking lots of water, since dehydration keeps you awake.
You also need to watch your caffeine, alcohol, sugar, and refined carbs intake because these will impact your sleep.
Don’t eat or drink too late in the evening– try to stop eating a few hours before you intend to sleep.
