Why Does A Hot Tub Make You Tired?

As society as a whole becomes more interested in health and wellbeing, it’s been found that getting a good night’s rest can play a fundamental role in overall wellness. This has led to a veritable industry designed to help people feel tired, fall asleep faster and experience a more uninterrupted slumber. But hot tub owners have long known that soaking in the warm and massaging waters before bedtime can lead to a better night’s sleep. So, why does a hot tub make you tired? To help explain the various processes that make this happen, we’ve put together this article.

Blood Circulation Boost

Soaking in warm water and being massaged by powerful water jets causes an increase in the body’s blood circulation. The heart begins beating faster and harder, oxygen and nutrients are more efficiently distributed, blood vessels and capillaries dilate, and the blood pressure falls. These processes promote tissue repair and the elimination of toxins. This also creates conditions that are conducive to drowsiness, rest and sleep. When blood circulation is restricted due to stress or cold temperatures, the circulatory system constricts, and blood pressure rises. This has been associated with difficulty falling asleep and reduced states of rest and relaxation. Spending time in a hot tub can improve your blood flow and make it easier to fall asleep at night.

Rest and Relaxation

It’s difficult to feel drowsy or tired when you’re unable to relax. Soaking in the warm massaging waters of a hot tub can help relax both your body and mind. Heat and massage can relax muscles by improving blood flow and flushing away toxins. Water buoyancy can reduce pressure on bones and weight-bearing joints while reducing any associated pain. Warm water and massage increase the production of pleasure-causing hormones such as oxytocin and endorphins that reduce both physical and mental strain. The state of relaxation created by spending time in a hot tub allows the body and mind to rest and feel calm.

Thermoregulatory Processes

The body’s internal temperature is controlled by a process known as thermoregulation. It’s been found that thermoregulation plays a role in signaling to the brain that it’s time to feel tired and sleepy. The body’s temperature increases upon awakening and continues to do so throughout the day. In the evening, the body temperature begins to decline which sends signals to the brain that it’s time to prepare for sleep. This can cause the onset of drowsiness. Soaking in a hot tub can simulate this natural body temperature cycle. Getting into the hot tub will temporarily increase the body temperature. Getting out leads to a drop in body temperature which sends signals to the brain that it’s time to prepare for sleep. This brings on feelings of tiredness. If you have problems falling asleep, a hot tub might be a useful tool.

Dehydration Caused by Heat

Spending time in a hot tub can also lead to dehydration which can have the effect of causing tiredness. As the heat of the water causes the body temperature to increase, the process of thermoregulation will attempt to reduce it by producing sweat. This can lead to a state of dehydration and can cause drowsiness to occur. This drowsiness is a signal from the body that more liquids need to be consumed. It’s important to ensure that you’re properly hydrated both before and after using a hot tub.
