Do We Need More Sleep In Winter Or Does It Just Seem That Way ? The Sleep Expert Explains

-


The amount of sleep we need does not depend on the seasons," says Theresa Schnorbach."However, certain factors associated with seasonal changes can contribute to a feeling of fatigue." According to Theresa Schnorbach, these are the main culprits:

1.Temperature Changes

“Temperature is one of the reasons why we sleep more in winter. At night, our body temperature usually drops by 0.5 to 1.5 °C. This makes it easier for us to fall asleep. However, changes in our environment can also cause a drop in our body temperature, as a result of which our body begins to prepare for sleep.

”Our ambient temperature can also make it harder to get out of bed in winter. After all, who wants to leave the comfort of their warm bed when the rest of the house is freezing cold?”

2. Less Light 

“The lack of natural light in winter causes us to produce more melatonin. That is the hormone that gives our body the signal that it is time to sleep. Our need to sleep more in winter is therefore related to the amount of light we are exposed to: a lower light intensity sends a signal to our brains that the body should prepare for sleep by producing melatonin.'

 “In winter, the nights are longer and we get less sunlight during the day. In addition, sunlight has a lower intensity in winter. This limited exposure to light explains why we feel more tired and need more sleep. Our brains don't get the same signal during the day to stay awake and alert as they do in the summer.'

3. The Holiday’s 

The holidays can also affect our sleep patterns and make us feel like we need more sleep. Staying up late to spend time with family, stressing over gifts, and other preparations for festivities can all disrupt your normal routine and make it harder to fall asleep. And that in turn leads to daytime fatigue.
