Many decide to crank up the heat overnight when it starts to get freezing cold but according to new research, it could be hurting your health.
Conducted by Slumberdown, the survey found that 46 percent of people who slept with their heating on felt sick in the morning with 37 percent reporting symptoms including headaches, dry mouth as well as dehydration.

While one in five people reported waking up in the middle of the night sweaty. Slumberdown sleep expert, Professor Jason Ellis shared:
“Our bodies do a great deal of work for us during sleep. As part of that process, our body temperature changes over the course of the night and we tend to cool down towards bedtime and then naturally warm up towards the morning. As such, we may go to bed warm and cosy but as the research shows, wake up hot and bothered. The key is being comfortable when going to bed and staying comfortable throughout the night.”
“The more comfortable you are the less likely you will wake during the night or too early in the morning.”

And if you step outside in the freezing cold, your body may be confused with the drastic change in temperature.
A consultant cardiologist at York Hospital, Dr. Maurice Pye, revealed to The Daily Mail:
“Temperature changes can affect the circulation quite dramatically. If you go from hot to cold, that can increase your blood pressure in a way that can affect blood supply to the heart. It causes a reflex that narrows the arteries, which reduces the blood supply to the heart muscle. This can cause angina, heart attacks or changes in heart rhythm.”
The takeaway? Be sure to invest in a down comforter for all seasons or have a fan running on low.
