A regular lack of sleep makes us feel exhausted right after waking up. Moreover, it’s one of the main reasons for gaining weight.
12. The wrong air temperature
Although falling asleep in warmth is pleasant, the optimal temperature is 60-75°F (15-23°C).
Solution: Cover up with a light blanket, and change it to a warm one during the night.
11. Physical exercise
A workout stimulates the nervous system, which is why falling asleep after going to the gym can be a problem.
Solution: Exercise no less than 3 hours before going to bed.
