My body temp is higher than normal at night during sleep, one time in the 100s. I'm a healthy 30 y.O., no smoking or drinking and my BP is fine. Why?

My body temp is higher than normal at night during sleep, one time in the 100s.  I'm a healthy 30 y.O., no smoking or drinking and my BP is fine. Why?

Diurnal variation: Human body sets it's temperature levels so the lowest (normal) temperature is in am, & highest (normal) temperature is at night. Normals vary among individuals, but in a given individual the temperature setting is rather constant. So your normal is 100 at night and perhaps 98 in am. Someone else maybe 96 in am & 98 at bedtime.

Set a time you want to wake up every morning, and get up at that time regardless of what time you sleep. Dont take naps during the day. ...Read more

When it's recommended that people get eight hours of sleep, is that supposed to be uninterrupted sleep? I wake two or three times a night. Thx.

When it's recommended that people get eight hours of sleep,  is that supposed to be uninterrupted sleep?  I wake two or three times a night.  Thx.

No: Most people don't sleep a full eight hours without interruption, especially after age 50. Waking to urinate is very common, especially in men due to prostate enlargement; but it is also common in women. Some awakenings are caused by pain, if this is the case, a dose of Acetaminophen at bedtime may make this less likely. If you fall asleep quickly after you wake, no problem. ...Read more
