If you sometimes have trouble waking up in the winter, you're not alone. The American Academy of Sleep Medicine suggests that the shorter daylight hours during winter can throw off your body's timings, making you feel more sleepy and sluggish during the day.
If this is seriously affecting your everyday life then you should speak to your doctor about the possibility of seasonal affective disorder (SAD). According to to the NHS, signs of SAD can include persistent low mood, irritability, loss of pleasure or interest in normal activities, and difficulty concentrating. Your doctor will be able to listen to your experiences, and suggest lifestyle changes, therapies, or other treatments that can help.
