What Are Night Sweats and How To Stop Them

Posted by Colin Hickey on

What does it mean when you wake up sweating? Sweating at night is an extremely common sleep issue for both women and men that could mean a host of different things - some harmless and some serious. Before you get too worried about why you’re sweating in bed, start by ruling out a few things, then talk to your health care provider.

Is your sleep environment causing excessive sweating at night?

First, take a full inventory of all aspects of your sleep environment. True night sweating - known as sleep hyperhidrosis - occurs independently of environmental factors. It’s persistent, drenches clothing and bedding, and is not caused by anything you’re in contact with while you sleep. Here are some questions to ask about your sleep environment – one or several of these things may be causing you to overheat and sweat while you’re trying to get your Zz’s.

  • What’s your home or bedroom thermostat set to? As recommended by the National Sleep Foundation, the recommended temperature for sleeping is between 60-67 degrees F. Your bedroom should emulate the environment of a cave – cool, quiet and dark.
  • Do you have a foam mattress? Memory foam retains more body heat than other mattress materials – it’s one of the top complaints from memory foam mattress users.
  • Are you using a mattress topper or pad? Mattress toppers, such as popular “egg crate” mattress toppers, memory foam mattress toppers and even “cooling gel mattress pads”might contain materials retain heat and cause hot sleep.
  • Is your sleepwear breathable enough? If your pajamas are flannel or wool, or if you’re wearing too many layers, you could be causing yourself to sleep hot. Consider less or layers and less clothing, and stick to lightweight cotton or bamboo cotton for cooler, comfortable sleep.
  • Do you sleep with a partner whose body heat is affecting your sleep temp? Your partner’s body heat while they’re sleeping is certainly something to consider when looking at your own temperature-related sleep problems. If your partner sleeps hot, you’re likely to be sleeping hotter as a result.
  • Is the underside of your bed breathable? The foundation or base of your bed is often overlooked as a reason for hot sleep. A base that allows great air circulation, such as a frame with slats or an adjustable base, is ideal for air flow.

Many of the above environmental factors - such as changing pajamas or adjusting your home or bedroom thermostat - can be easily changed. The BedJet Climate Comfort System for beds is also a great solution for the bedroom temperature issue as well as the issue of your partner sleeping hot. If you can’t agree with your partner on a comfortable thermostat setting in your bedroom, you can use the BedJet Dual Zone Cloud Sheet to customize cooling/warming temperatures on one partner’s side of the bed without affecting the partner’s other side.

If you’ve ruled out the above environmental factors as the culprit of your temperature-related sleep issues and determined that you’re experiencing true night sweats, below is a list of possible causes. You should absolutely talk to your healthcare provider right away if you feel any of these medical issues might be affecting you.
